Core Tip	This cohort evaluates postoperative venous geometry in relation to portomesenteric patency after pancreaticoduodenectomy with venous reconstruction. Follow-up began at baseline computed tomography acquisition, with recurrence-related vascular events and death treated as competing events. A wider splenic vein-portal vein angle remained associated with lower subsequent failure incidence after adjustment for the corresponding preoperative angle. Paired measurements showed individual anatomical changes in both directions. These findings support prospective evaluation of postoperative geometry for imaging-based risk assessment.
