Abstract:
In 34 patients femoro-distal reconstructions with umbilical vein grafts were assessed by means of pulsed Duplex sonography. Dilatations of the grafts and aneurysms were diagnosed easily by means of DS, likewise thrombotic plaques and perivascular pathologies. Haemodynamically significant stenoses can be quantified due to the increased velocity measured by pulsed Doppler. It can be concluded that DS is the method of choice for the postoperative follow-up of umbilical vein grafts of the femoro-distal vascular system.
