Abstract

Purpose: To assess the conformational changes of the common femoral artery (CFA) during hip joint flexion in patients without atherosclerosis.

Methods: Patients who underwent digital subtraction angiography for suspicion of arterial endofibrosis between 2007 and 2011 were retrospectively searched. Angiographic images were analyzed by two independent readers. The CFA was divided into four segments of equal length, and the segment containing the folding point was noted. Segments 1 and 2 were located in the proximal half of the CFA and segments 3 and 4 in the distal half. Readers assessed the CFA angulation, located the arterial folding point, and classified the CFA curvature as harmonious, or as a moderate or severe plication.

Results: Forty patients were included. The Lin concordance correlation coefficients, used to evaluate inter-observer variability, were 0.90 (95% CI [0.83; 0.96]), 0.96 (95% CI [0.93; 0.98]) and 0.96 (95% CI [0.94; 0.98]) for the measures of the CFA angle during flexion, of the length between the superficial circumflex iliac artery and the folding point, and of the length between the folding point and the femoral bifurcation, respectively. The CFA curvature was described as harmonious in 12 patients, moderate plication in 14 patients, and severe plication in 14 patients. The CFA folding point was located on segment 1, 2 and 3 in 6, 26 and 8 patients, respectively; no folding point was located on segment 4.

Conclusion: In these patients with non-atheromatous disease, hip flexion yielded most frequently a harmonious curvature or a moderate plication of the CFA.
