Abstract:
A 60-year male patient presented with a thoracoabdominal aortic aneurysm rupture, which was treated emergently with a modified off-the-shelf t-Branch stent-graft (COOK Medical Inc). The sole renal branch occluded 1 month after TEVAR due to branch compression, and the patient became anuric and temporarily dialysis-dependent. Despite the prolonged renal ischemia time, the occluded renal branch was successfully opened with thrombolysis and reinforced with a bare-metal stent. The patient recovered his renal function and came off dialysis.
