[Superselective angiography as a therapy control of femur head necrosis treated with a vascular pedicled pelvic bone graft].

This is a report of special operative therapy of idiopathic necrosis of the femoral head. This is based on the idea, that the necrosis of the femoral head is caused by an occlusion of the arteries of the femoral head, especially the arteria circumflexa femoris medialis. The necrotic area of the femoral head is filled up with a pedicle bone graft, which is apart from the spina iliaca and supplied from the art, circumflexa ilium profunda. From a total of 28 superselective angiographies of the arteria circumflexa femoris medialis, which where conducted preoperatively, a pathological finding was shown in 21 cases. Furthermore it is possible, to determine different courses of the art. circumflexa ilium profunda. A superselective angiography of the reset art. circumflexa ilium profunda was conducted in seven patients following the bone graft operation. These findings will be discussed. The angiographies were processed by electronic subtraction to better illustrate the state of the smallest vessels.
