Renal allograft implantation in respect of atypical vascular procedures

In minority of renal transplants it is unevitable to perform atypical vascular procedures of renal allograft implantation, which increases the risk of vascular complications, graft loss and lethality. In the presenting study, we retrospectively evaluated kinds of atypical vascular procedures in renal allograft implantation by donor type and the transplants outcome related to these procedures. From 1980 to 1998, a total of 463 patients (mean age 36.2+/-10.3), underwent renal transplantation (319 from living donor and 144 from cadaveric donor) at the Institute of Urology & Nephrology in Belgrade. Atypical vascular procedures of renal allograft implantation were representative for the some of the following cohorts: bypass grafting, endarterectomy, end to side both arterial and venous anastomotic site. A total of 45 patients (9.72%) underwent some of atypical vascular procedures (41 from living donor and 4 from cadaveric donor) (p<0.01). Among analyzed procedures, bypass grafting was performed in majority of cases (n=38). A total of 101 patients underwent endarterectomy. End to side both arterial and venous anastomotic site was done in two patients. Severe direct postoperative vascular complications following by lethal outcome appeared in 2 patients. Related to standardized, atypical vascular procedures had been of increased risk for appearance of severe vascular complication.
