“…As demonstrated by Iliopoulos et al [10], the superior mesenteric artery provides the dominant collateral supply to the IMA bed. In the acute setting, the contribution via branches of the IIAs is insignificant in patients with AAA or aortoiliac stenotic disease.…”

“…At the inferior mesenteric artery level, contradictory results are found from the literature with regard to the participation of this artery to the pelvic circulation (9,18,21). The median sacral artery is reported as a cause of endoleak after endovascular repair of aortic aneurysms (12) or as a collateral route to the occlusion of the common iliac artery (24).…”

The aim of the study was to estimate the functional contribution of the arterial inflow pathways to the pelvic circulation during walking in patients with stage 2 lower extremity arterial disease. Transcutaneous oxygen pressure (Ptc(O(2))) changes during exercise can be used to estimate the severity of regional blood flow impairment while walking. Seventy patients with stable lower limb claudication were studied using a multivariate linear regression model. The relationship between exercise-induced buttock Ptc(O(2)) changes, the ipsilateral calf Ptc(O(2)) changes, and the arterial diameters of the pelvic arteriographic pathways were analyzed. The ipsilateral hypogastric and lumbar pathway, as well as the ipsilateral calf Ptc(O(2)) changes, were the only variables significantly related to buttock Ptc(O(2)) changes (r = 0.47; P < 0.001). Their normalized respective contribution to the regressive model was 39%, 19%, and 18%. None of the contralateral hypogastric, mesenteric, and sacral pathways or pathways stemming from the external iliac artery showed significant correlation to buttock Ptc(O(2)) changes. The ipsilateral hypogastric and ipsilateral lumbar pathways are the major pathways responsible for the functional buttock blood flow supply during walking. The role of contralateral hypogastric, inferior mesenteric, and median sacral pathways and arteries distal to the internal iliac trunk is negligible in the normal or compensatory blood flow supply. Distal Ptc(O(2)) decrease at exercise aggravates proximal Ptc(O(2)) decrease, possibly through the occurrence of a "steal phenomenon" of distal over proximal circulation during walking.

“…If not enough collateral circulation exists, ischemia can occur in the colonic mucosa. 15 Most of the existing literature regarding endovascular repair of iliac vessels is in the setting of atherosclerotic disease. Emergency stenting cases are rare and limited to isolated case reports.…”

Traumatic iliac vessel injuries, especially secondary to penetrating wounds, are often associated with a very high mortality rate. The patients usually present to the trauma bay in profound hemorrhagic shock, which, in turn, triggers the vicious cycle of hypothermia, coagulopathy, and acidosis. Iliac artery injuries should be managed promptly because of the high incidence of late complications of pseudoaneurysm and arteriovenous fistulae and risks of subsequent arterial thrombosis and distal ischemia.We report a case of a 17-year-old female who was brought in following a stab wound in the right lower quadrant (RLQ). A postlaparotomy computed tomography (CT) scan performed revealed a pseudoaneurysm on the right common iliac. A pelvic angiography was performed, which was followed by an endovascular placement of a covered stent on the right common iliac artery.We discuss an interesting case along with discussion of relevant literature.
