Abstract
When renal artery occlusion occurs secondary to blunt trauma, the recovery rate of renal function after open revascularization is varied and far from satisfactory. Although the optimal treatment for this type of injury has not been established, percutaneous revascularization by endovascular stenting has recently been advocated for patients with unilateral renal artery occlusion. We herein report a case of blunt renal artery occlusion treated with an endovascular stent. After the placement of the stent, renal arteriography showed multiple nonflow-limiting contrast defects in the distal renal arteries, suggesting peripheral thrombosis. Although the duration of warm renal ischemia appears to be the crucial determinant of renal function, multiple thrombi in the distal renal arteries, which would be undetectable during open surgery, could also affect the functional outcome. The presence of these thrombi may explain the limited success of surgical revascularization in such cases.
