Resumo: Introduction: The retroperitoneum can present several pathologies that have a certain complexity and a poor prognosis due to their proximity to large vessels, the involvement of which complicates surgical approaches. Surgery is the therapeutic option associated with the longest survival. The objective of this study was to demonstrate that renal function can be preserved after ligation or resection of the left renal vein, without vascular reconstruction, if the collateral circulation remains functional. Case reports: We report two cases of patients with retroperitoneal tumors with local vascular invasion, the complete resection of which required division and ligation of the left renal vein. Postoperatively, both patients showed preserved renal function, because of collateral venous drainage, and vascular reconstruction was not necessary in either case. We also present a review of the literature on such cases. Conclusion: Division and ligation of the left  renal vein proved to be safe in both of the patients undergoing retroperitoneal tumor resection, and reconstruction of the vein is not mandatory when the collateral circulation is preserved.

La cirugía es la opción terapéutica asociada a la supervivencia prolongada. El estudio tiene por objetivo demostrar que es posible la preservación de la función renal, por las colaterales, después de la ligadura o resección de la vena renal izquierda sin reconstrucción vascular. Relato de los casos: Dos casos de pacientes con tumores retroperitoneales con invasión vascular local donde, para su completa resección, se hizo necesaria la sección y ligadura de la vena renal izquierda. Evolucionaron con preservación de la función renal debido al drenaje venoso por las colaterales, no siendo necesaria la reconstrucción vascular. Además, se realizó, para una mejor discusión de los casos, revisión bibliográfica. Conclusión: La sección y ligadura de la vena renal izquierda se mostró segura en los dos pacientes tratados con  resección de tumores retroperitoneales, no siendo su reconstrucción obligatoria cuando se preservaron las colaterales para drenaje venoso.Introdução: O retroperitônio pode apresentar diversas patologias e possui certa complexidade e mau prognóstico em virtude do íntimo contato e envolvimento de grandes vasos nas abordagens cirúrgicas.
