Inferior vena cava resection without reconstruction for retroperitoneal malignancies.

Inferior vena cava (IVC) involvement in retroperitoneal malignancies is a rare occurrence and radical surgery with major vascular resection represents the only potential curative treatment. IVC replacement after resection is still controversial and only small series and few prospective data are available. We report a series of three patients affected by retroperitoneal masses involving IVC treated with vena cava resection without replacement. All patients were treated by a radical R0 surgical procedure associated with infrarenal IVC resection and no reconstruction. Based on preoperative radiologic imaging and intraoperative findings, one patient also underwent right nephrectomy, while another patient underwent left renal vein ligation without nephrectomy. Neither early nor late severe post-operative complications related to the absence of IVC outflow were observed. Resection without replacement of the infrarenal IVC results in acceptable morbidity, thus specific risks related to the use of prosthetic grafts can be avoided.
