External Iliac Arterial Obstruction Caused by Satinsky Atrauma Forceps in Renal Transplantation.

External iliac arterial obstruction is relatively rare in renal transplantation, and may cause surgical failure and ipsilateral leg ischaemia. Prompt diagnosis and management of this kind of complication is essential to rescue the patient and allograft. Four patients with external iliac arterial obstruction caused by Satinsky atrauma forceps in renal transplantation were analysed and summarized. In case one, the obstruction of the external iliac artery distal to the renal allograft caused ipsilateral leg ischaemia. After surgical fixation of the endarterium, the patient recovered from the lower limb ischaemia. In case two, the obstruction of the external iliac artery was located proximal to the renal allograft. Since the endarterial rupture was not found and fixed in time, the renal allograft was lost. The third case was similar to the second. Based on the previous experience, we fixed the endarterium promptly and transplanted the kidney back successfully. In case four, there was endarterial rupture with atherosclerosis located around the anastomosis stoma. After taking out the atherosclerotic plaque and fixing the endarterium, the blood supply of kidney and lower limb was good. External iliac arterial rupture and obstruction caused by Satinsky atrauma forceps in renal transplantation is rare, but may cause severe and depressing outcome. The critical step is to find and fix the impaired endarterium as early as possible.
