It is generally accepted that the medial circumflex femoral artery nourishes about two-thirds to four-fifths of the femoral head. In order to study the arteries in the idiopathic ischemic necrosis of the femoral head in adults, selective medial circumflex femoral arteriography was performed on 24 affected hips and 14 normal hips. This method enabled the better visualization of the medial circumflex femoral arterial system than the conventional femoral or internal iliac arteriography. The affected hips showed similar vascular patterns compared to normal hips. Anastomoses between the ascending branch or the medial circumflex femoral artery and the gluteal arteries, however, were rarely found in the affected hips. In the affected hips, various pathologic changes were demonstrated angiographically mainly in the portion of the ascending branch and the retinacular arteries. The existence of some degree of vascular insufficiency of the femoral head was assumed. However, complete occlusion of the medial circumflex femoral artery and its main branches that might cause head necrosis was seldom observed.
一般认为，旋股内侧动脉滋养股骨头约三分之二至五分之四的区域。为研究成人特发性股骨头缺血性坏死的动脉情况，对24个患髋和14个正常髋进行了选择性旋股内侧动脉造影。与传统的股动脉或髂内动脉造影相比，该方法能更好地显示旋股内侧动脉系统。患髋与正常髋显示出相似的血管模式。然而，在患髋中很少发现旋股内侧动脉升支与臀动脉之间的吻合。在患髋中，血管造影显示主要在升支和支持带动脉部分出现各种病理变化。推测股骨头存在一定程度的血管供血不足。然而，很少观察到旋股内侧动脉及其主要分支完全闭塞，而这可能导致股骨头坏死。
