A 69-year-old male presented with hematemesis. a contrast-enhanced computed tomography demonstrated pseudoaneurysm in the gallbladder (circle); b angiography from the replaced right hepatic artery revealed two cystic arteries (black arrow and arrowhead); c the selection of the right-sided cystic artery (black arrow) was difficult, and a 1.3-Fr microcatheter (DeFrictor Nano; Medico's Hirata, Osaka, Japan) was used. Superselective angiography through the cystic artery showed a pseudoaneurysm (circle); d and e advancing just the coil section of the 0.010-inch Target Nano coil (Stryker, Fremont, CA, USA), which measures 1 mm in diameter and 3 cm in length, into the microcatheter and ensuring that the detachment point is slightly within the catheter hub (white arrowhead), allows for successful detachment; f two 0.010-inch coils were placed (white arrow) using the intentional early detachment technique. The left-sided cystic artery was easily selected with a 1.6-Fr catheter (Carnelian MARVEL S; Tokai Medical Products, Aichi, Japan) and embolized with three detachable coils using the standard method; g angiography after embolization revealed the complete embolization of the pseudoaneurysm
