- Abstract
In conclusion, at the L2-L3 levels, the lumbar veins are not paired, and in most cases, only the right side of L2 and the left side of L3 as a common trunk flow into the IVC, although preoperative CT often failed to visualize the lumbar veins. Abbreviations & Acronyms CT computed tomography IVC inferior vena cava L2-LLV L2 left lumbar vein L2-RLV L2 right lumbar vein L3-CT common trunk of the L3 lumbar vein L3-LLV L3 left lumbar vein L3-RLV L3 right lumbar vein RPLND retroperitoneal lymph node dissection UTUC upper tract urothelial carcinoma During IVC dissection, such as right RPLND or thrombectomy for tumors with IVC thrombus, the branching of the IVC is important.1,2 The lumbar veins were thought to flow into the IVC in pairs on the left and right sides, but the details remain to be elucidated.3-5 We have reported a retroperitoneoscopic RPLND for UTUC in the lateral decubitus position; this approach has the advantage of easy observation of the dorsal surface of the IVC and the entrance of the lumbar veins.6 In the present study, we investigated the number and course of the L2-L3 lumbar veins with specific emphasis on entry into the IVC on preoperative CT and on surgery of the retroperitoneoscopic right RPLND. The steps during en bloc dissection of the right-sided retroperitoneal lymph nodes dissection and the intraoperative findings in L2 right lumbar vein and the common trunk of L3 lumbar vein are demonstrated.
