Ischemic lumbosacral plexopathy after embolization of type 2 endoleak: Progress and functional outcome

Abstract

Peripheral nerve injuries, including plexopathy, are an important cause of disability with the neurological sequelae affecting activities of daily living and quality of life. Lumbosacral plexopathy represents a distinct entity of peripheral nerve disorders due to its relative rarity.The lumbosacral plexus represents the nerve supply to the lower back, pelvis, and legs and is derived from the ventral rami of the L1-S4 nerve roots. 1 Common etiologies for lumbosacral plexopathy including diabetes, neoplastic invasion, radiation, trauma, infection, inflammatory, infiltrative, and vascular causes like ischemia, hemorrhage, and direct compression by aortoiliac aneurysm. 1 The lumbosacral plexus has a very rich vascular supply from the five lumbar arteries that originate from the abdominal aorta, the deep circumflex iliac artery that branches from the external iliac artery, and the iliolumbar and gluteal branches of the internal iliac artery. 2 Due
