Sciatic nerve compression by an aneurysm of the internal iliac artery. 1985

J A Geelen, and R de Graaff, and R G Biemans, and R L Prevo, and P W Koch

A 73-year-old female with severe sciatica suffered from an aneurysm of the left internal iliac artery. At first minimal caudographic abnormalities suggested intervertebral disc herniation and lumbar root compression but at exploratory surgery the diagnosis had to be rejected. Once the correct diagnosis was established by echography, CT-scanning and angiography surgical treatment of the aneurysm resulted in complete recovery. Because sciatic nerve lesions due to aneurysms in the pelvic region very seldom occur and may be the cause of diagnostic confusion, symptoms and treatment of these aneurysms are discussed.

UI	MeSH Term	Description	Entries
D007083	Iliac Artery	Either of two large arteries originating from the abdominal aorta; they supply blood to the pelvis, abdominal wall and legs.	Deep Circumflex Iliac Artery,Arteries, Iliac,Artery, Iliac,Iliac Arteries
D009408	Nerve Compression Syndromes	Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.

D000783	Aneurysm	Pathological outpouching or sac-like dilatation in the wall of any blood vessel (ARTERIES or VEINS) or the heart (HEART ANEURYSM). It indicates a thin and weakened area in the wall which may later rupture. Aneurysms are classified by location, etiology, or other characteristics.

D012584	Sciatic Nerve	A nerve which originates in the lumbar and sacral spinal cord (L4 to S3) and supplies motor and sensory innervation to the lower extremity. The sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. It has two major branches, the TIBIAL NERVE and the PERONEAL NERVE.
