title: Vascular injury and repair associated with retroperitoneal lymphadenectomy for nonseminomatous germinal cell tumours of the testis.
abstract: Metastatic disease adjacent to major vascular structures in the retroperitoneum sometimes necessitates planned removal of portions of these vessels, or the vessels may inadvertently be injured when retroperitoneal lymphadenectomy is performed. In 78 patients who underwent retroperitoneal lymphadenectomy, 17 (22%) required vascular repair intraoperatively. The vena cava was most frequently involved (eight cases) followed by inadvertent injury to the renal arteries (five cases) or the infrarenal aorta (three cases). Resection of the infrarenal aorta was planned in two cases without postoperative complication. In six cases a resection of either the whole inferior vena cava or a portion of it was needed to remove all of the tumour. There were nine cases of inadvertent injury to the aorta, vena cava or a renal artery. The outcome after arterial repair was satisfactory with the exception of the inadvertent renal artery injuries, which required nephrectomy in three cases. Leg swelling was not a long-term sequela of either caval repair or resection.
