Percutaneous Direct Embolization for Pseudoaneurysm at the Gallbladder Fossa after Cholecystectomy.

Postoperative pseudoaneurysm at the gallbladder fossa is a rare complication of cholecystectomy. The typical clinical presentations of this condition are intraparenchymal or intraperitoneal hemorrhage or rupture into the gastrointestinal tract, and this may be life-threatening. For the treatment of pseudoaneurysms, percutaneous transarterial embolization is considered first-line. We present a case of pseudoaneurysm at the gallbladder following cholecystectomy, which was successfully treated with echo-guided percutaneous transhepatic direct embolization using N-butyl cyanoacrylate, after the failure of transarterial embolization.
