Background:
Unintentional renal artery occlusion after endovascular aortic aneurysm repair (EVAR) is an uncommon phenomenon. The sequelae from this specific complication are severe; consequently, the topic of renal artery coverage is a pertinent issue. We present a case series of patients undergoing EVAR with unintentional renal artery coverage, review the treatment options available, and suggest a treatment algorithm for this scenario based on the evidence.
Methods And Results:
We report four patients who were found to have renal artery occlusion after EVAR detected up to 5 weeks postoperatively. Renal revascularization was achieved using endovascular renal artery stenting in two patients, and open hepato-spleno-renal bypass in the remaining two cases. Treatment strategies used led to symptom resolution and recovery of renal function in all cases.
Conclusions:
Both open and endovascular techniques may be used as procedures to treat this condition-the choice of procedure is primarily determined by accessibility of the renal orifice.
