Common iliac artery aneurysm: Expansion rate and results of open surgical and endovascular repair

Abstract

The expansion rate of CIAAs is 0.29 cm/y, and hypertension predicts faster expansion. Because no rupture of a CIAA <3.8 cm was observed, elective repair of asymptomatic patients with CIAA >or=3.5 cm seems justified. Although buttock claudication after EVAR remains a concern, results at 3 years support EVAR as a first-line treatment for most anatomically suitable patients who require CIAA repair. Patients with compressive symptoms or those with AVF should preferentially be treated with OR.

Isolated iliac artery aneurysms: a comparison of surgical method and endovascular approaches

“…[25] ise olaya farklı bir açıdan bakarak, 1986 ile 1995 yılları arasında 438 hastadaki 715 ana iliyak arter anevrizmasını inceledikleri çalışmalarında hastaları üç gruba ayırmışlardır. Birinci grup abdominal aort anevrizmaları ile birlikte bulunan ana İAA'lı hastalardan, 2. grup internal İAA'ları ile birlikte ana İAA'sı olan hastalardan, 3. grup ise izole İAA'lı hastalardan oluşmuştur.…”

Surgical Repair of Arteriovenous Fistula Associated with Iinfrarenal Aorto-iliac Aneurysm: Report of Two Contrasting Cases

“…[1][2][3] Aneurysmal erosion into the venous system is the most common etiology for communication between the two systems. [1][2][3] The erosion results from spontaneous rupture of an atherosclerotic aneurysm directly into the adjacent vein. The current theory behind the development of these fistulas is that pressure and tension from large aneurysms produce necrosis of the aortic wall.…”

“…[1][2][3] This relatively high mortality rate is attributed to other co-morbidities as age, coronary artery disease and congestive heart failure.…”

“…They can occur secondary to erosion of either an abdominal aortic aneurysm (AAA) or common iliac artery aneurysms (CIAAs) into the adjacent vena cava. [1][2][3] The reported incidence is 0.3%-1.5% of all patients undergoing surgical treatment for aorto-iliac aneuryms [1][2][3] and 6.4%-8.8% among those operated on for ruptured aneurysms. 1,2,4) Classic teaching describes AVF presenting with the triad of symptoms: congestive heart failure, a continuous abdominal bruit, and a pulsating abdominal mass.…”

“…However, the clinical presentation can be subtle and varied leading to a lack of a preoperative diagnosis. 2,5) Consequently, massive bleeding can ensue intra-operatively. Therefore, an astute preoperative diagnosis can help in identifying optimal operative approaches and minimize intra-op blood loss.…”
