Endovascular treatment of hepatic artery aneurysm by multilayer stents: two cases and one-year follow-up.

We wished to analyze our initial experience with the Cardiatis Multilayer Stent for visceral artery aneurysms. Two males with a hepatic artery aneurysm (34 mm and 48 mm in diameter, respectively) were treated, via a percutaneous femoral approach, with multilayer stents. We deployed the stent in front of the aneurysm neck, covering the hepatic artery branches. At 12 months, a computed tomography scan showed thrombosis of the aneurysmal sac and patency of all the branches of the hepatic artery. The Multilayer Stent appears to be a viable alternative for the treatment of visceral artery aneurysms in patients at high surgical risk, but long-term follow-up is needed.
