Here, we describe the case of a 73\u2010year\u2010old woman with DIVC, who underwent robot\u2010assisted surgery (RS) for rectal cancer. In this case, 3D CT angiography showed DIVC with an interiliac vein from the left common iliac vein and a tortuous aorta. Intraoperatively, we identified the presence of the left IVC in addition to the inferior mesenteric vein, gonadal vein, and ureter, which require meticulous attention during vascular processing. By optimizing the port placement, we were able to ensure mobility of the robotic arm and sufficient field of view to safely perform a robot\u2010assisted anterior resection with lymph node dissection. Careful preoperative assessment and development of a strategy for port placement using CT imaging are essential in avoiding iatrogenic injury and performing safe RS.<\/jats:p>","DOI":"10.1111\/ases.13080","type":"journal-article","created":{"date-parts":[[2022,6,29]],"date-time":"2022-06-29T04:49:01Z","timestamp":1656478141000},"page":"832-835","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Robot\u2010assisted
