The iliolumbar artery is the first branch of the posterior trunk of the internal iliac artery. [1] It turns upward behind the obturator nerve and the external iliac artery and vein, to the medial border of the psoas major muscle, behind which it divides into: Lumbar branch of iliolumbar artery; Iliac branch of iliolumbar artery
An online survey conducted by the Cleveland Clinic of 1,174 men 18 years or older, found that 72% of men would rather do household tasks, such as cleaning the bathroom or mowing the lawn, than see ...
The iliolumbar vein is the vena comitans of the iliolumbar artery. The obturator nerve crosses superficial to it. [1] A single vein is found more commonly than a double vein. [2] It drains vertebral segments four and five. [3] It is closely related to the ascending lumbar vein. [3]
The iliac branch of the iliolumbar artery (ramus iliacus) descends to supply the iliacus muscle; some offsets, running between the muscle and the bone, anastomose with the iliac branches of the obturator artery; one of these enters an oblique canal to supply the bone, while others run along the crest of the ilium, distributing branches to the gluteal and abdominal muscles, and anastomosing in ...
Typically, the artery divides into an anterior division and a posterior division, with the posterior division giving rise to the superior gluteal, iliolumbar, and lateral sacral arteries. The rest usually arise from the anterior division. Because it is variable, an artery may not be a direct branch, but instead might arise off a direct branch.
Intermittent claudication most commonly manifests in men older than 50 years. [citation needed] One in five of the middle-aged (65–75 years) population of the United Kingdom have evidence of peripheral arterial disease on clinical examination, although only a quarter of them have symptoms.
Because of its similarities to deep vein thrombosis (DVT), May–Thurner syndrome is rarely diagnosed amongst the general population. In this condition, the right iliac artery sequesters and compresses the left common iliac vein against the lumbar section of the spine, [5] resulting in swelling of the legs and ankles, pain, tingling, and/or numbness in the legs and feet.

A. Pelvic and lower extremity radiograph shows extensive calcification of the femoral arteries. B. Translumbar aortography shows near-total obstruction of the femoral arteries. Mönckeberg's arteriosclerosis, or Mönckeberg's sclerosis, is a non-inflammatory form of arteriosclerosis (artery hardening), which differs from atherosclerosis ...
