Management of aneurysms involving branches of the celiac and superior mesenteric arteries: A comparison of surgical and endovascular therapy

A, Computed tomography angiography (CTA) demonstrates a 2.6 cm splenic artery aneurysm. B, Angiogram of splenic artery aneurysm before stent deployment. C, Angiogram of splenic artery aneurysm after stent-graft deployment. D, Postoperative CTA demonstrating aneurysm exclusion by stent-graft (arrow). Heterogeneity of splenic tissue represents differences in flow dynamics between arterial supply and venous sinusoids.

A, Angiogram of splenic artery aneurysm before coil embolization. B, Angiogram of splenic artery aneurysm after coil embolization.

Before (A) and after (B) stent-graft deployment for a proper hepatic artery pseudoaneurysm originating distal to the gastroduodenal artery. The brachial artery was used for the approach.
