Abstract
Angiographic findings are described in a patient with enlarged persistent sciatic arteries and a ruptured sciatic artery aneurysm. The left persistent sciatic artery was patent and dilated to a width of 10 cm throughout its length. It had ruptured in the lower thigh. The common iliac, internal iliac, and both sciatic arteries were dilated and tortuous, with generally smooth outlines. Some patchy calcification in the arterial wall was noted. Arterial flow was extremely slow in the dilated arteries, requiring very delayed films to show the right sciatic artery as far as its bifurcation at the knee.
