Abstract:
320 sides of origin of the obturator artery and the blood vessels related to the fe-moral ring of Chinese adults were studied. There were 309 instances with a single ob-turator artery (254 arose from the internal iliac artery and 55 from the external iliacartery) and 11 cases with double obturator arteries.The internal iliac origin of the obturator artery bore no relation to the branchingtypes of internal iliac artery.The anomalous obturator artery which originated from the external iliac artery ap-peared in 20% of the total specimens. This frequency corresponds with that of theJapanese, but lower than that of the Europeans and Americans. Sex and side failed toshow any difference.The courses of the anomalous obturator arteries and their relation to the femoralring were analyzed. The artery which passed through the medial side of the femoral ring and behind the lacunare ligament, is of clinical importance and was found in 5% of the specimens observed. The percentage is higher than that reported in the literature.Besides, there were comparatively larger veins which ran medially to the femoral ring and opened into the external iliac vein (found in 42.5%).
