Although arterial pseudoaneurysm is one of the most serious complications after pancreatic surgery, the best practice with maximum efficacy and minimum adverse effects to overcome such a serious situation has not yet been elucidated. We performed endovascular micro-arterial stenting (EMAS) to manage this serious situation while preserving a sufficient hepatic arterial flow, and herein report the technical details and challenges of the procedure. Dilation of the stent using a balloon catheter to adhere to the parent artery, and embolization of the surrounding artery to prevent type I and type II endo-leaks are the most important points for ensuring a successful procedure. We applied this technique to 6 cases of hepatic arterial pseudoaneurysm, with a mean size of 6.5 ± 1.3 mm. The mean time of the procedure was 81 ± 22 min, without adverse events, including hepatic necrosis or arterial bleeding. EMAS may be the ideal procedure for treating pseudoaneurysm after pancreatic surgery while preserving the hepatic arterial inflow.
