Portal Vein Stent Placement in Five Patients with Chronic Portal Vein Thrombosis Prior to Pancreatic Surgery

J Vasc Interv Radiol. 2016 Jun;27(6):889-94. doi: 10.1016/j.jvir.2015.11.057. Epub 2016 Jun 3.

Abstract

Five patients with pancreatic tumors and chronic portal vein (PV) thrombosis underwent PV stent placement before surgery. The patients either had resectable tumors or locally advanced tumors with stable, partial, or complete response to neoadjuvant therapy. PV stent placement removed periportal collaterals in all cases, with no complications, in a mean time of 150 minutes. Patients received a daily dose of subcutaneous low-molecular-weight heparin until 12 hours before surgery, and low-molecular-weight heparin was resumed for 30 days after surgery. Surgery was performed 1 day to 3 months after PV stent placement, with no complications related to periportal collaterals.
