Objectives• After studying this chapter, you will be able

to:– Recognize the relevant anatomy and

physiology of the neurological system– Summarize the pathology that prompts

surgical intervention of the neurological system and the related terminology

– Determine any special preoperative neurological diagnostic procedures/tests

Objectives (cont’d.)– Indicate the names and uses of neurosurgical

instruments, supplies, and drugs– Indicate the names and uses of special

equipment related to neurosurgery– Determine the intraoperative preparation of

the patient undergoing a neurosurgical procedure

Objectives (cont’d.)– Interpret the purpose and expected outcomes

of the neurosurgical procedures– Recognize the immediate postoperative care

and possible complications of the neurosurgical procedures

– Assess any specific variations related to the preoperative, intraoperative, and postoperative care of the neurosurgical patient

Introduction to Neurological Surgery   

• Characteristics of neurological surgery– One of the most sophisticated surgical

specialties – Encompasses advanced surgical and imaging

technology– Surgery involves the brain, spinal cord,

peripheral nerves, and protective structures– Common indications include congenital

defects, traumatic injury, degeneration, and cancer

Cranial Procedures• There are several options available for a

variety of cranial procedures– There are also a number of commonalities for

these procedures• Refer to text

Spinal Procedures• Performed by either a neurosurgeon or an

orthopedic surgeon– Neurosurgeons are almost always involved in

cervical procedures, but both intervene in lumbar procedures

• There are a number of commonalities for these procedures– Refer to text

Spinal Procedures (cont’d.)• Include:

– Lumbar laminectomy for diskectomy with spinal fixation

– Microdecompression endoscopic spinal diskectomy

– Anterior cervical diskectomy and fusion (ACDF): Cloward technique

Peripheral Nerve Procedures• Nervous system of the human body is

divided into two systems– Central nervous system (CNS): brain and

spinal cord– Peripheral nervous system (PNS): nerves that

link the various parts of the body to the CNS• Includes cranial and spinal nerves• Trauma and various compression syndromes that

affect the PNS often lead to surgery
