BACKGROUND: Vascular failures are serious complications in pancreas transplantation. Open surgery is a reliable and quick intervention method, but it carries a risk of infection and bleeding. Endovascular procedures are rare among patients after a SPK, but are becoming more frequently used. One of the main risks of the endovascular approach is that the renal function impairment caused by contrast agent.

MATERIAL AND METHODS: We performed a retrospective analysis of 200 transplanted pancreases at our center over the last 14 years. The analyses included those patients after pancreas transplantation who required the most challenging vascular interventions and ones that were non-standard for the procedure.

RESULTS: Severe vascular conditions requiring endovascular intervention were observed in 3% of SPKs. In one retransplanted patient, there was an acute ischemia of the lower extremity due to the narrowing of the common iliac artery following a previous transplantectomy, above the new pancreas graft anastomoses. In another patient, local inflammation led to the disruption of the external iliac artery on the level of transplantectomy, caused severe bleeding, and we had to implement a stent-graft to reconstruct the iliac artery wall. A third patient had a pseudoaneurysm demanding further treatment with a stent-graft implemented into the femoral artery due to a pseudoaneurysm of the right external iliac artery.

CONCLUSIONS: Intravenous interventions in patients with a transplanted or retransplanted pancreas are safe and feasible. It is a technically demanding procedure, but the risk of kidney graft function deterioration, as well as of bleeding due to the high dose of heparin used, is lower than with open vascular surgery.
