A 30-year-old male presented with an abdominal lump and was diagnosed with nonseminomatous germ cell tumor (International Germ Cell Cancer Collaborative Group [IGCCCG] poor risk). The serum tumor markers at presentation were serum alpha fetoprotein (SAFP): 209.8 ng/mL, serum beta-human chorionic gonadotropin (Sβ-hCG): 830009 mIU/mL, and serum lactate dehydrogenase (SLDH): 2051 U/L. The patient had a high pulmonary burden of disease and dyspnea, and hence four cycles of VIP (ifosfamide/etoposide/cisplatin) chemotherapy were administered. The administration of bleomycin was avoided. On re-evaluation of the contrast-enhanced computed tomography scan, our patient had multiple large residual retroperitoneal nodes with inferior vena cava (IVC) infiltration ([Fig. 1]). The tumor markers had dropped to normal limits, SAFP: 6 ng/mL, Sβ-hCG: 3.1 mIU/mL, and SLDH: 210 U/L. He underwent retroperitoneal lymph node dissection with IVC resection and reconstruction using expanded polytetrafluoroethylene (PTFE) graft. Intraoperatively, the infrarenal IVC was involved by the tumor for a length of 5 cm, just proximal to the bifurcation, with no collateral formation. The tumor mass was dissected off from the abdominal aorta and the retroperitoneum, till it was attached only to IVC ([Fig. 2A] and [B] ). After gaining vascular control of bilateral renal veins and proximal and distal IVC, 5000 IU of heparin was given and a vascular resection was performed. The lumbar venous tributaries were ligated and divided. The vein was reconstructed using expanded PTFE graft and anastomosis performed using 3–0 polypropylene sutures ([Fig. 2C] and [D]). The total IVC clamping time was 20 minutes. End-tidal CO2 was monitored intraoperatively to rule out any pulmonary thromboembolic event. As the IVC was clamped infrarenally, there was no fall in blood pressure noted during the entire procedure. Postoperative course was uneventful and patient was started on anticoagulants. The patency of graft was confirmed using Doppler study. The histopathology was suggestive of presence of viable tumor with IVC wall infiltration.

Postchemotherapy retroperitoneal lymph node dissection forms an integral part of management of testicular tumors. IVC involvement by residual tumor mandating surgical resection is reported in 7 to 11% cases.[1] The proposed pathways leading to IVC involvement include direct vascular spread through right gonadal vein or lymphatic metastasis leading to external compression/infiltration.[2] Donohue et al reported the largest series of 75 patients citing the following reasons for IVC resection: inability to remove tumor thrombus by cavotomy alone (33%), tumor adherent to or invading the cava (58%), and IVC occlusion by scar tissue (8%).[3] The presence of teratoma/viable tumor in 80% of such surgically resected specimen highlights the oncological significance of complete tumor clearance at the expense of vascular resection. Furthermore, 77% concordance was seen between the pathology of retroperitoneal node and tumor thrombus.[4] This underlines the need for an aggressive approach for the management of residual disease. A mathematical model to predict the need for IVC intervention based on the residual tumor size and IGCCCG classification has been proposed; however, it needs validation.[5] The need for IVC reconstruction is based on the presence of collateral vessels. In the presence of collaterals, resection of infrarenal IVC requires no reconstruction. In the absence of collaterals, expanded PTFE graft appears to be the conduit of choice as compared with the vein grafts.[6] The complications reported specific to IVC resection include lower limb edema, ascites, chylothorax, deep venous thrombosis, pulmonary embolism, and renal insufficiency; however, these all generally resolve with time.[3]
