[Isolated iliac aneurysms. Sixty-seven cases in forty-eight patients]

77 pure iliac aneurysms where detected in a group of 48 patients along a period of 21 years, and represented 12.3% of all patients having aortic, iliac, or aorto-iliac aneurysms. The study group comprised 42 men and 6 women, 48-86 years old (mean 67.8 years). The aneurysm was located on the right side in 51.9%, on left side in 48.1%. The affection of the common iliac arteries (70.1%) was more frequent than it was on the internal iliac arteries (18.2%), or in the external iliac arteries (11.7%). The diameter was from 2 to 10 cms. 44 patients out of 48 (91.6%) where symptomatic, and 15 presented a rupture syndrome (31.3%). 10 patients (20.8%) had a pulsating mass. The etiology was unknown in 8 cases (16.7%); 2 patients had a mycotic aneurysm (4.2%). The remaining 38 patients (79.1%) had an aneurysm of atheromatous origin. 5 arteritic patients (10.4%) did not have any cure for their aneurysm, because it was considered threatening for 4 of them. The fifth patient was not treated because the artery was so calcified that it could not be clamped. A lumbar sympathectomy on the same side of the lesion was realised, in addition to the peripheral surgical act for arteritis. One patient had an endoaneurysmorrhaphy, another had an exclusion by ligature section of the aneurysm. For the remaining 41 patients (83.1%) the aneurysms where flattened, and vascular continuity was re-established by a prosthesis. 7 patients (12%) decreased post-operatively.(ABSTRACT TRUNCATED AT 250 WORDS)
