Interventional treatment of visceral aneurysms:an investigation of therapeutic technique / 介入放射学杂志

ABSTRACT

Objective To evaluate interventional techniques for the treatment of visceral aneurysms. Methods A total of 11 aneurysms were found in 9 patients with visceral aneurysms who received interventional treatment. Of the 9 patients, single aneurysm at both superior mesenteric artery (SMA) and right colonic artery was seen in one, 2 aneurysms at same splenic artery in one, one aneurysm at splenic artery in 5, aneurysm at right gastric artery in one and pseudoaneurysm at hepatic artery in one. In 9 patients the transcatheter endovascular coil embolization was successfully carried out for 10 aneurysms, including splenic (n = 7), right colonic artery (n = 1), right gastric artery (n = 1) and hepatic pseudoaneurysm (n = 1). One stent-graft was used for the SMA aneurysm. Results Technical success was achieved in all cases without any serious complications. Conclusion Interventional embolization with coils can successfully occlude most visceral aneurysms, while stent-graft should be used when the aneurysm is difficult to be occluded with coil.
