Comparison of patency rates and clinical impact of different reconstruction methods following portal/superior mesenteric vein resection during pancreatectomy

Primary repair following PVR/SMVR is preferred and can be achieved in most situations. Stenosis should be noted when with risk factors (long segmental and tension), but it produced little clinical impact. Synthetic grafting was associated with a higher thrombosis rate. Acute thrombosis is associated with increased mortality and decreased survival.
