Chest Wall Resection/Reconstruction

• Multidisciplinary approach – Individualize patient

– Thoracic skeleton

– Soft tissue

– Critical care

• Etiological factors – Tumor

• Primary

• Metastasis

• Recurrent

– Radiation

– Trauma

– Infection


1. Pleural cavity

2. Skeletal support

3. Soft tissue coverage

4. Postoperative critical care


• Pleural cavity

– Pleural drainage

• air tight

– Muscle flap transposition

– Omentum transfer

– Pneumoperitoneum

– Thoracoplasty

– Eloesser flap

– Diaphragm reconstruction


• Skeletal support – Fascia lata

– Bone (Rib graft)

– Teflon

– Silicone

– Mesh • PTFE

• Prolene

• Marlex

• Vicryl

– Methyl methacrylate sandwich

– Struts – PLA and titanium

– Bovine pericardium (Veritas)

– Alloderm


Thoracic Skeleton

• Defects four contiguous ribs or greater

than 5 centimeters (The Rule)

– Chest wall stabilization (paradoxical motion)

– Protect vital organs

• May not need to reconstruct larger defects

if previous radiation therapy (Exception)

• Posterior defects are well tolerated

– Posterior ribs 1 – 3 (4) – Hinge point

– Scapula protection (Exception)

Osteogenic Sarcoma of Chest Wall

Polypropylene vs PTFE Mesh

• Operator dependent

• Polypropylene more

difficult to stretch

without wrinkles

• PTFE is watertight,

easier to handle

• Mayo Clinic

experience showed

little difference *

Methyl Methacrylate / Mesh Sandwich

• Prevention of

paradoxical

respiration

• Improved chest

contour

• Treatment of choice

for large skeletal

defects in many

institutions

Multiple Reconstruction Products PTFE and Methyl Methacrylate Sandwich


Methyl Methacrylate / Mesh Sandwich

• Non-randomized study comparing methyl

methacrylate and PTFE

Methyl

methacrylate PTFE

Morbidity 5.2% (2/38) 24% (5/21)

Paradoxical

respiration 2.6% (1/38) 24% (5/21)

Journal Invest Surg 2006

Bovine Pericardium

Acellular Dermal Matrix


• Potential use in contaminated fields

• Experimental data shows greater implant-

defect interface strength than PTFE at 4

weeks *

• Little long term clinical data

– Tensile strength

– Lung herniation

– Paradoxical chest wall motion

Flail Chest

• Thoracic Trauma is seen in 20% of all trauma

• TT is cause of death in 25% of trauma cases

• Over 50% of the TT is rib fractures

• 1/13 pts (8%) have a flail chest

• Definition: More than 2 continuous rib fractures

at two separate sites

– Pulmonary Contusion

– Hemopneumthorax

– Associated injuries

Flail Chest

• Paradoxical motion (External)

• Pulmonary contusion

• Severe pleurtic pain

• Decreased tidal volume

• Alveoli collapse

• Arteriovenous shunting

• Hypoxemia

• Respiratory insufficiency

Flail Chest

Treatment

• Pain control – Narcotics, NSAIDs, Intercostal blocks, Epidural

catheter

• Aggressive physiotherapy (FOB)

• Careful fluid administration

• Pulmonary support (Internal stabilization)

– Intubation

– BIPAP

Flail Chest

Treatment

• Chest wall stability

• External stability (historical)

• Rib fixation (Limited size 8 – 12 mm, Thin

cortex, Continued movement)

– K wires (intramedullary)

– Anterior metal plating

– Locking systems (metal)

– Absorbable plates

Flail Chest Indications

• Flail chest

– Failure to wean

– Paradoxical motion weaning

– No pulmonary contusion

• Reduction of pain and disability

– Painful movable rib

– Failure of narcotics/epidural

– Fracture movement worsens pain

– Minimal associated injuries (ISS)

• Chest wall deformity

– Loss of chest wall integrity (crush injury)

• Non-Union rib fracture (> 2 months)

• Other thoracic surgery required

Sternal Plating

Primary Sternal Plating

• Rigid plate fixation in 45 high risk patients

• Matched control group of 207 patients

• Mediastinal infection

– Control group 14.8%

– Rigid fixation group 0%

Eur J of Card Thor Surgery 2004

CW Reconstruction and Rib Fixation

• Thoracic skeleton reconstruction

– Small defects no reconstruction or mesh

– Large defects MMS, PTFE or TT struts

• Soft tissue reconstruction

– Small defects: latissimus dorsi or pectoralis

– Large defects: rectus abdominis, possible free flap

• Location and etiology is most important

• New chest wall product stabilization are

promising

Summary

• Keys to success in these complex cases:

– Total resection of the disease process

– Reconstruction of chest wall integrity

– Soft tissue coverage

• Team of physicians well versed in:

– Chest wall resection and reconstruction

• Prosthetic materials

– Free or pedicle flaps

– Critical care of the patient

Conclusions

• Chest wall reconstruction and rib fixation is

both safe and effective

• Each patient should be individualized

– Review old operative reports

– Review previous treatments regiments

– Life expectancy

– Quality of life

• Earlier treatment in warranted

• Team approach is mandatory
