Renal vascular injuries.
Fifteen patients with injuries to the renal arteries and/or veins have been treated in the past ten years. Nine injuries were the result of gunshot wounds, and six were from blunt trauma. Twelve patients presented to the emergency department in shock; two of these did not have a palpable blood pressure. Time from admission to time of operation averaged 6.4 hr for patients with blunt trauma and 1.25 hr for patients with penetrating trauma. Seven patients had ten associated abdominal vascular injuries, and two patients had injuries to both the right renal artery and left renal vein. Associated nonvascular abdominal injuries were found in all 15 patients. Efforts were made to repair renal vascular injuries with suture or grafting of the injured vessel in eight cases (53%). These efforts were successful in four patients, but in four the repair failed and a nephrectomy could not be avoided. Two patients died in the operating room or immediately postop in spite of successful repair of their renovascular injury. One injured left renal vein was ligated and nephrectomy was not necessary. In five patients, ligation of the injured renal artery and nephrectomy were necessary. There were five deaths (33%). Three of the deaths occurred in the operating room and two were postoperative deaths. Only one of the patients who died had a renal vessel injury without other major vessels involved. He did, however, have serious liver and kidney injuries. Multiple associated vascular, nonvascular, and head injuries were present in all four of the other deaths. We have continued to take an aggressive approach to exploration, isolation of the injury, and repair of the vessel whenever possible if a renal vessel injury is suspected.(ABSTRACT TRUNCATED AT 250 WORDS)
