Vascular complications of allograft nephrectomy.
OBJECTIVE
To identify risk factors that predisposes patients to vascular complications from allograft nephrectomy and to determine the safe management of this group of patients.


METHODS
This is a retrospective review of 1543 renal transplants performed in our institution between January 1990 and January 2002.


METHODS
During this period, 161 (10.4%) transplant nephrectomies were performed, of which we identified nine patients (5.6%) who sustained significant vascular complications.


RESULTS
Seven patients required ligation of external iliac artery for control of haemorrhage. Immediate vascular reconstructions (femoral-femoral cross-over bypass in two cases and one vein patch to an external iliac artery defect) were performed in three patients. Two patients had endovascular stenting of their external iliac artery pseudoaneurysm. No patient suffered limb loss. However, three patients died-two died from overwhelming sepsis and one patient died of an intra-cerebral haemorrhage.


CONCLUSIONS
While vascular complications associated with transplant nephrectomy are relatively rare, they are associated with a significantly poor outcome. Immediate attempts to reconstruct the vascular supply to the lower limb are associated with a high complication rate. We advocate that where possible, vascular reconstruction should be deferred and that external iliac artery ligation can be performed safely with surprisingly low limb ischaemia rate.
