title: Type I aneurysmosis: complementary index for diagnosis.
abstract: The aim of this study was to investigate the diameters of the superficial femoral artery (SFA) and the popliteal artery (PA) in patients with type I aneurysmosis (diffuse aneurysm in the aortoiliac-common femoral segments combined with arteriomegaly of the femoropopliteal segments). The ratio between these diameters (SFA/PA index) was calculated. A retrospective study was carried out on 76 limbs of 38 patients with type I aneurysmosis. The SFA/PA index calculated on these patients was compared with the index of a control group: 76 limbs of 38 patients with abdominal aortic aneurysm. The SFA/PA index proved to be <1.00 in the limbs of patients with type I aneurysmosis, whereas it was > or =1.00 in all patients with an abdominal aortic aneurysm. There was a statistically significant difference between the type I aneurysmosis group and the control group (p < .001). This finding can be considered a complementary sign in the diagnosis of type I aneurysmosis.
