The diagnosis of the avascular necrosis of the femoral head (AVN) had advanced. RI scan intrasseous pressure monitoring interamedullary venography CT, MRI, and selective femoral angiography are used in diagnosis. Among these methods selective or superselective angiography is necessary to study the change of the vessels of the hip because the vascular insufficiency could be a major etiology of AVN, Selective femoral angiography was performed for 23 hips of 22 patients who were suspected as AVN by simple radiographs and RI scans in order to estimate the change of vascularity of the femoral head. The results were as follow. 1, The alteration of vasculature appeared in 21 cases among all 23 cases (91%) which included 100% in the traumatic group (4/4 cases) and 90% in nontraumatic group (17/19cases.) 2. The affected vessles in nontraumatic group were the proximal portion of the posterior branch of the medical circumflex artery in 2 cases the midportion of posterior branch in 2 cases the distal portion of the posterior branch in 11 cases and superior capsular branch in 2 cases. 3. The affected vessels in traumatic group were proximal portion in 1 cases midportion in 1 cases and superior capsular artrey in 2 cases. 4. The obstruction of inferior casular artery was noted in 6 cases of nontraumatic group. 5. the retrograde filling of the posterior branch of medial circumflex artery were noted in 1 cases from superior gluteal artery in 1 cases from inferior gluteal artery in 1 cases from superior and inferior gluteal artery and regrograde filling of inferior gluteal artery from medial circumflex artery was in 6 cases.
