[Superselective electronic subtraction angiography. Experience in 6 surgically treated hips using the double cup prosthesis].
Six hips in five patients with Wagner double cup surface replacement prostheses were examined by superselective angiography of the medial femoral circumflex artery to determine a possible relationship between a lesion of the artery and loosening of one or other components of the prosthesis. Electronic subtraction of the angiographic images allowed a precise appreciation to be made of the condition of the vessels. No relationship was found. Lesions of the medial femoral circumflex artery were found, even when the prosthesis was firmly in place. This finding is contrary to that of authors who consider that an extra-osseous vascular lesion always leads to bone necrosis and loosening in double cup surface replacement prostheses.
