Figure 1From: Complete and safe resection of challenging retroperitoneal tumors: anticipation of multi-organ and major vascular resection and use of adjunct proceduresRetroperitoneal Tumor Involvement of the Inferior Vena Cava (IVC). Preoperative computed tomography scan demonstrates IVC involvement without obvious venous collateralization (a). The tumor was resected en bloc with a portion of the IVC (b) and reconstructed using synthetic polytetrafluoroethylene (PTFE) tube graft (c). Follow-up imaging was done postoperatively (d).Back to article page
