Aim. The aim of this study was to review published litera-ture concerning the use of compression treatments in themanagement of venous and lymphatic diseases and esta-blish where reliable evidence exists to justify the use ofmedical compression and where further research is requi-red to address areas of uncertainty.Methods. The authors searched medical literature databa-ses and reviewed their own collections of papers, mono-graphs and books for papers providing information aboutthe effects of compression and randomized clinical trialsof compression devices. Papers were classified in accor-dance with the recommendations of the GRADE group tocategorize their scientific reliability. Further classificationwas made according to the particular clinical problem thatwas addressed in the papers. The review included paperson compression stockings, bandages and intermittent pneu-matic compression devices.Results. The International Compression Club met once inVienna and corresponded by email in order to reach anagreement of how the data should be interpreted. A widerange of compression levels was reported to be effective.Low levels of compression 10-30 mmHg applied by stockingsare effective in the management of telangiectases after scle-rotherapy, varicose veins in pregnancy, the prevention ofedema and deep vein thrombosis (DVT). High levels of com-pression produced by bandaging and strong compressionstockings (30-40 mmHg) are effective at healing leg ulcersand preventing progression of post-thrombotic syndromeas well as in the management of lymphedema. In some areas
no reliable evidence was available to permit recommenda-tions of level of compression or duration of treatment. Theseincluded: management of varicose veins to prevent pro-gression, following surgical treatment or sclerotherapy forvaricose veins, and the level of compression required totreat acute DVT.Conclusion. This review shows that whilst good evidencefor the use of compression is available in some clinical indi-cations, there is much still to be discovered. Little is knowabout dosimetry in compression, for how long and at whatlevel compression should be applied. The differing effectsof elastic and short-stretch compression are also little under-stood.[Int Angiol 2008;27:193-219]

Compression therapy is recognized as an effec-tive treatment in the management of venous andlymphatic disease since thousands of years . Untilrecently evidence of efficacy was based on empi-rical study and little objective research had beenperformed. More detailed information has nowbeen obtained from published clinical series andrandomized controlled trials. These have beensummarized in books and monographs.1-8 Natio-nal and international guidelines on compressiontreatment have been published by a number ofdifferent societies.9-15 Many of the publishedrecommendations which suggest particular levels

of compression to be used in specific indicationsare based on the experience of the authors ratherthan on evidence from clinical trials.16, 17
The main aim of this document is to give anoverview of existing knowledge, identifying areasof knowledge where good scientific evidence isavailable from clinical trials and areas for whichlittle or no evidence is available and which shouldbecome the subject of future research.
Materials and methods
The International Compression Club (ICC) isan ad hoc group of experts which includes clini-cians involved in the management of patients withvenous disease as well as technical specialists fromcompanies manufacturing compression devicesfor clinical use. This group was to review and tocomment critically on published literature on com-pression therapy concentrating on two issues:
1. experimental findings concerning clinicallyrelevant effects of compression therapy;
2. randomized clinical trials (RCTs) addressingthe use of compression for particular clinical indi-cations.
The ICC searched medical literature databasesas well as their own collections of papers in orderto find relevant medical literature.
The findings were presented by several mem-
bers of the group and discussed at a meeting ofthe ICC, held in May 2007 in Vienna, Austria. Theassessment of the strength of the recommenda-tions from randomized trials was based on thescoring criteria from the international GRADEgroup.18 Thereafter, the data were summarized intables that were circulated among the membersof the ICC by e-mail. The corrected version of thesetables was agreed by a majority of the active par-ticipants at a follow-up ICC meeting, held inNovember 2007 in Paris.
Results
The outcome of this initiative is summarized inTables I and II; details are given in the Appendix(Tables IA and IIA) .The tables are structured inalignment with the clinical stages of the CEAPclassification 171 supplemented by the indicationsof deep vein thrombosis (DVT), post-thromboticsyndrome and lymphedema.
A number of different methods of classifyingcompression garments is used and varies fromcountry to country. The tables are constructedusing the interface pressure of medical compres-sion stockings (MCS) given in millimeters of mer-cury (mmHg) ranges to avoid any confusion. Byinternational agreement, compression applied tothe limb by a stocking is calculated from an analy-

sis of the mechanical properties of the stockingsby manufacturers and not by direct interface pres-sure measurement. The pressure ranges corre-spond to the values that are assumed to be exer-ted on the ankle region based on in vitro measu-rements by the manufacturers for a certain rangeof leg circumferences.172, 173 These pressure ran-ges may not always be exactly the same as thosegiven in the individual publications due to diffe-rent national classification systems.
Intermittent pneumatic compression (IPC) isincluded since it offers an interesting model tostudy physiological effects of compression the-rapy.
Experimental data
Table I presents the summary of experimentaldata describing effects of compression therapy ondifferent physiological parameters. Table IA in theAppendix gives more detailed information. Themain focus of the outcome was put on vascularproblems of the extremities, to some extent sup-plemented by outcomes and findings from resear-
ch into trauma. However, effects of compressionon burns, scar formation or on the general circu-lation were not reviewed.
Several experimental studies demonstrated thatcompression stockings from all three pressureranges considered here are able to prevent and toreduce leg edema.19-29 External pressure increa-ses the tissue pressure.123 Interestingly a low pres-sure around 10 mmHg is enough to impede legswelling in a prolonged upright position.19-21 Dra-matic decrease of edema was also demonstratedafter IPC.30-34
Reduction of venous diameter and increase ofvenous flow velocity depend on the relative valuesof intravenous pressure and compression pres-sure. In the supine position, light antithromboticstockings are able to decrease venous diameterand to increase venous flow velocity.35-37, 49 Somestudies were unable to detect an increase of venousflow velocity by duplex ultrasonography.124-126
There are a number of factors which limits theaccuracy of duplex ultrasound in this application,but it should be noted that peak flow velocity mea-

sured in this way is a rather poor parameter tocharacterize the mean flow velocity under a com-pression stocking. IPC produced clearly detecta-ble flow acceleration in several experimental stu-dies.38-48 In the upright position, much higherexternal pressures are necessary in order to redu-ce the diameter of leg veins.49-51, 127 This explainsthe fact that reduction of venous reflux measuredin the upright position could only be demonstra-ted under high compression pressure exerted bystrong stockings, bandages or a Velcro-band devi-ce.52-55
Several plethysmographic studies performed inpatients with chronic venous insufficiency showedan improvement of the venous pump was produ-ced by the application of MCS, bandages 56-62 andby a Velcro band device.53
Conflicting results have been reported whenvenous function was assessed by measurement ofambulatory venous hypertension in patients withchronic venous insufficiency. Two studies assessedthe effect of application of strong stockings 64 andby strong short stretch bandages 63 and found areduction of the peak pressure values during walking.Other reports, which measured the reduction invenous pressure during walking were unable to finda significant improvement of ambulatory venoushypertension.59, 124 This example shows that an agree-ment concerning the interpretation of venous pres-sure measurements is still lacking.
The influence of external compression on thearterial flow is a critical issue. In a number of stu-dies performed especially on supine or recliningvolunteers, it was found that a sustained externalpressure >60 mmHg will diminish local bloodflow.128-131 Bandages and elastic wraps exerting apressure of around 30 mmHg do not reduce sub-bandage flow, but diminish toe perfusion.132 Innormal extremities, inelastic bandages with a pres-sure of 38 mmHg increase blood perfusion,66
13-23 mmHg arm-sleeves increase blood flow.65
An impressive series of experiments shows une-quivocally that IPC increases arterial inflow.67-76
Special devices producing short phases of pres-sure waves up to 180 mmHg have been shown toincrease arterial flow, even in patients with arte-rial occlusive disease and in severe stages of ische-mia.69-71, 73-76
Effects of compression on different microcir-culatory parameters have been reported. LaserDoppler flux in the skin increases up to a pressu-re of 20 mmHg in the supine position, and up to60 mmHg in the sitting position.77 MCS are ableto reduce capillary filtration and pericapillaryedema,78-82 to tighten paracellular junctions 83 andto increase capillary density,79, 80 thereby impro-ving tissue oxygenation.81, 82, 84 One study was una-ble to demonstrate a profibrinolytic effect of ela-stic bandages.133
Data from investigation of the microcirculationand release of biomarkers come from studies whereIPC was applied to the extremities.84-90, 134-140 Seve-ral studies describe an increase of capillary per-fusion and of tissue oxygenation,77, 84-87 which isin accordance with the observation of an increa-sed release of nitric oxide,88, 89 with an up regula-tion of the fibrinolytic potential of endothelialcells 88, 136, 137 and with a suppression of procoa-gulant activation.140 Some reports did not find anincrease of fibrinolytic activity after IPC.138, 139 Theincrease of bone mineral density after IPC 134, 135
shows that IPC is able to influence other tissuesof the limbs, and is not limited to effects on theskin microcirculation.
Experimental data concerning the effect of con-ventional compression therapy on lymphedemaare sparse.91-96 IPC is able to reduce the water con-tent of a lymphedematous extremity withoutimproving the lymphatic drainage to an adequa-te amount.95, 96 This leads to an increase of theoncotic tissue pressure 96 necessitating a conti-nuation of compression therapy by bandages andstockings.
Randomized clinical trials
In those areas in which reviews and meta-analy-ses already exist, only papers published after thesereviews were included in Table II.
For the assessment of the RCTs, the recentlyproposed GRADE system to score the recom-mendation-level of each study was used.18 Recom-mendations defined as strong (grade 1) or weak(grade 2) refer to the text in the outcome-column(Table II and Table IIA in the Appendix). The qua-lity of evidence is classified as high (grade A) ormoderate (grade B) according to the study desi-

gn and the consistency of the results. Observa-tional studies or case series corresponding to therecommendation grade C were not taken intoaccount. The ratings were based on the votes ofthe majority of the active participants at the ICCmeetings.
Several RCTs have proved the clinical efficacyof light compression stockings with a pressure<20 mmHg in the following indications:
— improvement of symptoms of venous disea-se, such as heaviness in patients with CEAP C0s-C1s 98, 99 and in varicose veins of pregnancy 101
(Grade 1B);— prevention of leg swelling related to pro-
longed sitting and standing (“occupational legedema”) (recommendation level Grade 1B);21
— prevention of venous thromboembolism inbed-ridden patients, especially after general sur-gery (Grade 1A).110-112, 168
Some trials revealed that low pressure stockingshave no, or only doubtful, benefits following vari-cose vein surgery (Grade 2B).147-149, 151
MCS with a pressure range of 20-30 mmHg pro-duce beneficial clinical effects (Grade 1B recom-mendations):
— after sclerotherapy of small teleangiecta-sias;100
— concerning an improvement of subjectivesymptoms in varicose veins of pregnancy;101
— for the treatment of acute DVT.113, 114
The recommendations for using compressionstockings with a pressure range of 20-30 mmHgin patients with asymptomatic or symptomaticvaricose veins,143, 144 for the prevention of varico-se veins after surgery 146 or of venous edema 24
and for treating venous ulcers 163 are weak (allGrades 2B).
For MCS with a pressure range between 30 and40 mmHg randomized controlled trials could befound allowing strong recommendations:
— better outcome after sclerotherapy compa-red to light bandages;108
— such stockings are able to reduce lipoder-matosclerotic areas on the leg (CEAP C4b) 102 andto heal venous ulcers 104-106 (all Grade 1B);
— MCS reduce the recurrence rate of venousulcers after healing, higher pressure ranges seemto be superior 103, 152 (Grade 1A);
— two studies were able to demonstrate thatthe rate of post-thrombotic syndrome after proxi-mal DVT can be reduced by wearing compressionstockings with 30-40 mmHg for the following years117, 118 (Grade 1A). One three-part study performedin a restricted number of patients failed to showa beneficial effect of stockings 1 year after DVT169 (Grade 2B).
Up to now no convincing data are available sup-porting the use of compression stockings inpatients with post-thrombotic syndrome 119 (Grade2B).
For the use of compression bandages strongrecommendations can be given:
— in patients with venous ulcers (CEAP C6) 107
(Grade 1A);— for the management of acute DVT 113, 115, 116
and lymphoedemaedema 120, 121 (both Grade 1B);— high pressure bandages reduce bleeding
after venous surgery,109 but lose pressure morethan MCS.150 For patient comfort stockings maybe better tolerated than bandages 108, 145 (all Grade1 B).
The classical model to assess the efficacy of com-pression therapy is the venous leg ulcer. In thisindication an extensive Cochrane review showedthat:
— compression is better than no compressionand higher pressure exerted by multilayer ban-dages provides better results than low pressure107, 164 (Grade 1A-C);
— four-layer bandages were shown to be moreeffective than three-155 or two-layer-bandages,156
than the “usual system of care” 157, 164 and thansingle layers of short stretch bandages 158, 161 (Grade1B);
— a Velcro-band device achieved faster ulcer-healing than four layer bandages 162 (Grade 1B);
— several trials did not show significant diffe-rences of ulcer healing rates between four layerand short stretch systems 153, 154, 159, 160, 164 (Grade1B).
For IPC the present level of evidence in ulcerhealing is weak.165-167 Strong levels of evidencesupport the use of IPC:
— in the area of thrombosis prevention aftersurgery 111, 112 (Grade 1A);
198 INTERNATIONAL ANGIOLOGY June 2008
— in the treatment of post-thrombotic syn-drome;119
— in lymphedema 122 (both Grade 1B).
Discussion and conclusions
Our analysis focuses on the following three mainpoints which have considerable practical impor-tance:
1. What is the effective range of compressionpressure?
2. Are there differences concerning the modeof action depending on different compressionmaterial?
3. Which are the main points to be investiga-ted in future research?
These points are discussed on the basis of thepresented data, both concerning experimental andrandomized clinical studies.
Compression pressure
The levels of compression which have beenshown to be effective in different experiments arein the range between 5-10 mmHg and >120 mmHg.It is crucial to differentiate between sustained andintermittent pressure. Data from studies of theskin microcirculation show that ischemic skindamage may result from high levels of compres-sion applied for a long period of time. Dependingon the body position and the particular anatomi-cal location of the compressed skin, a sustainedpressure of 60-70 mmHg may be considered as amaximum upper limit, especially over bony pro-minences in patients with normal arterial circu-lation.128-130
In contrast, experiments with intermittent pneu-matic pumps have demonstrated an increase ofarterial blood flow using short-duration pressurepeaks >120 mmHg followed by intervals of lowpressure. These findings have been obtained involunteers with normal arterial circulation as wellas in patients with arterial occlusive disease.67-76
It was found that the relative increase of arterialflow was more pronounced in the upright (sitting)position than in the supine position.67
Light stockings (10-15 mmHg) have been repor-ted to provide beneficial effects through reduc-
tion of edema formation after prolonged sittingand standing, and an increase of venous bloodflow velocity in the supine position.19-21, 35 Theycan also be used as a “liner” to keep local ulcerdressings in place. A second stocking applied overthis liner has been introduced by some compa-nies as a special kit for treating venous ulcers.
In the upright position, higher pressures weremore effective with regard to narrowing of legveins, the decrease of venous reflux and the enhan-cement of venous pump function in patients withchronic venous insufficiency.51, 53-55 Some experi-ments were able to demonstrate a dose-responserelationship between the interface pressure andan experimental effect. High pressure, but not lowpressure, is able to reduce ambulatory venoushypertension.63
Intermittent compression not only improvesarterial inflow and microcirculation, but also hasprofound effects on the release of anti-inflam-matory, vasoactive and anticoagulatory mediatorsand substances.88-90, 136, 137, 140
Compression material
The elastic properties of the compression devi-ce play a crucial role in the relationship betweensustained (resting) pressure and the pressureduring standing and walking (working pressu-re).
A sustained pressure that is maintained day andnight is achieved by material containing elasticfibers (MCS, long-stretch, elastic bandages) whilestiff and short stretch material exerts a lowerresting pressure and high pressure peaks duringwalking, comparable to the action of intermittentpressure pumps which produce peaks by inflationof inelastic cuffs. MCS that exert a pressure of 40mmHg and more are not only difficult to apply,but in most cases also not well tolerated duringrest. If a pressure of >40 mmHg is required, it maybe preferable to achieve this with material withhigh stiffness, such as inelastic, short-stretch ban-dages, multilayer bandages or adhesive or cohe-sive bandages.
Some experiments have shown that in spite ofexerting the same resting pressure, inelastic ban-dage systems or Velcro-band devices achievemore-pronounced hemodynamic effects than ela-

stic material.53, 54 This can be explained by thehigher pressure peaks (working pressure) underthe inelastic material. With inelastic bandages,pressure peaks of 80 mmHg and more can bemeasured during walking. When the patients liedown the pressure will decline to a resting pres-sure of about 40 mmHg which is tolerable.174 Themost impressive demonstration of hemodyna-mic effects comes from experiments with inter-mittent pneumatic pumps, which can be consi-dered as models for walking with completely ine-lastic devices.
Comparisons between different compressionmaterials have been done principally in studiesinvolving patients with venous leg ulcers. It mustbe kept in mind that the application techniqueand the pressure exerted vary enormously depen-ding on the skill and the experience of the ban-dager. This is an important consideration whenevaluating studies comparing different kinds ofcompression bandages. Another important pointto be considered is possible misleading reportingin some trials, for instance when the use of a localulcer dressing together with one padding layerand one bandage layer is declared as a “three-layerbandage”. The best healing rates of venous ulcersreported to date were obtained by multilayer ban-dages expected to exert pressures of ≥40 mmHg(Grade 1A).107 In recent years, several RCTs havebeen published demonstrating better healing rateswith specially designed double-layer compressionstockings in comparison to different compressionbandages (Grade 1B).104-106, 163
Randomized controlled trials proving the cli-nical efficacy of IPC exist especially for the indi-cation of mechanical prevention of venous throm-boembolism (Grade 1A) 110-112 and for lymphede-ma (Grade 1B).122 Specially designed IPC systemshave shown promising results in patients witharterial occlusive disease.69-71, 73-76
Areas of poor knowledge (future studies needed)
EXPERIMENTAL DATA DEFICITS
Some areas in which future experiments shouldclarify open questions or endorse sparse existingobservations are summarized below:
— relationship between pressure/material/time(=dose) and volume reduction (=response) in thetreatment of edema, initial phase and mainte-nance phase of therapy, level and duration ofsustained and intermittent pressure;
— mechanism of action of different kinds ofpressure applications, effects on the physical andbiochemical properties of different tissue com-partments and on lymph-drainage;
— dose-response relationship for different pres-sures and materials on venous reflux, venous pumpand ambulatory venous hypertension;
— influence of MCS and bandages on the arte-rial circulation;
— influence of MCS and bandages on themicrocirculation, on endothelial cells, cytokines,and mediators (some data are available after IPC);
— rationale for pressure gradient in differentbody positions;
— local increase of pressure by positive eccen-tric compression: what is the experimental prooffor the efficacy of local pressure pads?
— loss of interface pressure over time with dif-ferent compression materials, correlated withchange of efficacy.
NEED FOR RANDOMIZED CLINICAL TRIALS
In general, the pressure of the compression devi-ces tested for different indications is only vaguelydescribed in the existing RCTs. In the case of MCSa compression class or a pressure range indica-ted by the manufacturers is usually given, but thepressure exerted on the individual leg remainsunclear. This is even more of a problem with com-pression bandages. There are hints coming fromexperimental and from clinical trials that the cli-nical effect of a compression product will chan-ge with the exerted pressure, which thereforeshould be measured in future trials.174
Indications in which the efficacy of compres-sion therapy is not yet well documented by RCTscorrespond to the white areas in Table II and arelisted below:
— symptomatic and asymptomatic varicoseveins (CEAP C1, C2, a,s): is compression therapyable to prevent progression and complications?
— what is the role of compression in the mana-gement of venous edema (C3)?
— sclerotherapy and interventional procedu-res of varicose veins: the quality of the compres-sion products in the reported trials is often que-stionable and the outcome parameters are weak.Up to now, no single trial compared compressionversus no compression following removal of vari-cose veins (C2) or refluxing veins (C3-C6) by sur-gery or endovenous procedures;
— optimal compression therapy for the ambu-lant management of acute DVT, adjusted to thelevel and extent of DVT and to the mobility of thepatient;
— superficial phlebitis: no single RCT demon-strates the effect of compression;
— role of compression therapy in the mana-gement of post-thrombotic syndrome;
— lymphedema: most existing RCTs comparecompression as one element of complex physicaldecongestion therapy with the same basic treat-ment in addition to another modality;
— correlation between pressure (measured invitro and in vivo) and clinical effects (reductionof edema, improvement of lipodermatosclerosis,healing rate of venous ulcers, recurrence rate afterulcer healing, improvement of pain and swellingin acute DVT);
— efficacy of newly-developed devices, e.g. supe-rimposed MCS, new pumps.
