Key result
En-block vena cava and right kidney resection yields no postoperative intercurrence at 14 months.
Case Report (n=1)
En-block resection with wide margins and prosthetic reconstruction of the inferior vena cava is a viable surgical treatment for primary leiomyosarcoma to prevent relapses.
Single-case report suggests feasibility of en bloc resection for middle IVC leiomyosarcoma; leaves open optimal reconstruction and long-term outcomes.
Retroperitoneal sarcomas are responsible for 10-15% of all sarcomas in soft tissue. Leiomyosarcoma of the inferior vena cava has a slow growth rate, and the initial symptoms are related to the affected segment of the vein. A 56-year-old woman with leiomyosarcoma of the middle segment of the inferior vena cava underwent en-block resection of the affected segment of the vena cava and the right kidney. The inferior segment of the vena cava was tied, and the superior segment was anastomosed to the left renal vein using a polyester prosthesis. The patient was followed for 14 months and did not present any postoperative intercurrence. In conclusion, the leiomyosarcoma is a rare tumor that should be surgically treated with wide margin resections in order to prevent relapses.

Reges et al. (2008) conducted a case report in Leiomyosarcoma of the inferior vena cava (n=1). En-block resection of the affected segment of the vena cava and the right kidney with prosthetic reconstruction was evaluated on Postoperative intercurrence. En-block resection of the affected segment of the vena cava and right kidney with prosthetic reconstruction resulted in no postoperative intercurrence at 14 months.
