[Vascular pedicled iliac bone graft in therapy of femur head necrosis in the adult. Clinical and angiographic results].

23 hip joints with hip head necrosis in 22 patients were provided with a pedicle bone-graft perfused by the art. circumflexa ilium profunda. I two cases it was necessary to remove the bone-graft contralaterally because bone had already been removed from the side with the necrosis at an earlier date. In these cases the arterio-venous bundle of vessels of the autologous heterotope transplant was connected through microanastomosis with the arteria and vena circumflexa femoris lateralis. In addition to the usual clinical follow-up the method of superselective angiography was also applied to make possible direct perfusion control of the implanted bone-graft in the operated patients. In 18 of the 23 pedicle autologous heterotope transplants unimpeded perfusion could be shown. By introducing regional stress angiography in 7 cases it became possible to make further well-founded statements about the physiotherapeutical follow-up treatment. Electronic subtraction provides a more accurate assessment of even the minutest arteries possible.
