[Complications in pancreatic duct occlusion: passage of the occlusant into the venous system]

In two cases, occlusion of the residual pancreas remaining after a Whipple's procedure was associated with a "spillover" of the occlusant into the venous system of the pancreas, resulting in one of the cases in embolisation of intrahepatic branches of the portal vein. In both cases, the parenchyma of the residual pancreas was well preserved. The cause of the spillover into the venous system was the injection of a too large volume into the ductal system, with subsequent rupture of small side branches. To avoid this rare complication, the filling of the ductal system should be carried out under intraoperative radiological control.
