Inferior Vena Cava (IVC) Resection Without Reconstruction for a Large IVC Leiomyosarcoma.

Retroperitoneal tumours arising from the inferior vena cava (IVC) are rare tumours often requiring large vessel resection for complete surgical excision. Limited exposure to such tumours often discourages surgeons from offering surgical resection to these patients, depriving them of the only potentially curative modality. We present here the surgical technique for resection of a large IVC sarcoma without IVC reconstruction. A 53-year-old lady presented with a large retroperitoneal sarcoma encasing the infra-hepatic IVC with tumour thrombus extension into the hepatic cloaca as well as the left renal vein. Surgical resection was planned as the disease remained stable after 2 cycles of neoadjuvant chemotherapy with adriamycin and ifosfamide. Complete surgical excision of the tumour was achieved by performing a resection of the entire length of infra-hepatic IVC and right kidney, without IVC reconstruction. Left renal vein was divided after careful preservation of a draining collateral. Tumour thrombus was extracted from the hepatic cloaca, and proximal IVC stump closure was achieved with preservation of right hepatic vein insertion. Total blood loss during the procedure was 2300 mL, and the patient recovered without compromise of renal function or development of lower limb oedema. IVC resection without reconstruction can be safely performed for large retroperitoneal sarcomas involving major vascular structures. Familiarity with the retroperitoneal, retro-hepatic and supra-hepatic anatomy is paramount to achieving good surgical outcomes. © 2022. The Society for Surgery of the Alimentary Tract.
