Pancreas transplantation with isolated splenic artery blood supply - Single center experience

The blood supply of the native pancreas by three arterial lines from the celiac trunk system (splenic artery and common hepatic artery) and the superior mesenteric artery forces surgeons to perform vascular reconstruction to provide sufficient intra-organ blood flow into the graft. The purpose of our study was to assess the possibility of pancreas transplantation with an isolated splenic artery blood supply.

From January 2012 to July 2018, simultaneous pancreas-kidney transplantation (SPKT) was performed in 21 patients. Gender: male - 11 (52,4%), female 10 (47,6%). Recipients aged 26 to 54, the median age was 38 [34; 42] years. In 6 (28,6%) recipients, the organ perfusion was carried out through the splenic artery alone; in the rest, it was performed through the splenic and inferior pancreaticoduodenal artery exiting from the superior mesenteric artery of the graft. The transplant function, the quality of carbohydrate metabolism compensation, the objective characteristics of intra-organ blood flow was assessed.

There were no statistically significant differences in the volume blood flow characteristics revealed by CT-perfusion and laboratory data in the study groups.

Based on the assessment of the function and quality of blood supply to the transplant, the possibility of performing pancreas transplantation with an isolated splenic artery blood supply had been proved.
