Interventional therapy of pseudoaneurysm in extremities or kidneys / 介入放射学杂志

ABSTRACT

Objective To evaluate the value of covered metallic stent and arterial embolization in the management of pseudoaneurysm of extremities or kidneys.Methods Endovascular covered stent graft was inserted for isolation of peripheral extremity pseudoaneurysm in 3 patients and intraarterial embolization was performed with gelfoam in 2 patients for pseudoaneurysm in kidney.Results All 5 pseudoaneurysms kept occluded after the treatment.Distal arterial pulse was normal in 2 patients treated with stent graft;new thrombosis formed within the stent during the procedure but disappeared after thrombolytic therapy through catheter in 1 case;and still another new pseudoaneurysm presented at puncture site in 1 other case due to other factors.Conclusions Pseudoaneurysms in extremities or kidneys can be effectively treated with interventional techniques of covered stent graft and percutaneous arterial embolization.The long-term investigation is needed.
