Clinical Usefulness of the Triaxial System in Emergency Transarterial Embolization with N-butyl-2-cyanoacrylate: A Report of Two Cases

抄録

We report two cases of acute arterial hemorrhage successfully treated by transarterial embolization, using the triaxial system and n-butyl-2-cyanoacrylate (NBCA). Case 1 is a 78-year-old man with a large hematoma in the rectus abdominis muscle. Case 2 is a 63-year-old man with massive jejunal bleeding and shock. In both cases, severe coagulopathy was present, and safe embolization with NBCA was necessary. In the triaxial system, which consists of a 1.9-French (F) microcatheter, a 2.7-F high-flow microcatheter, and a 4-F catheter, the high-flow microcatheter introduced through the 4-F catheter usually acts as supporting catheter to advance the 1.9-F microcatheter distally. In our cases, the high-flow microcatheter was also useful for the prevention of NBCA reflux into an untargeted artery, and thus, safe embolization could be performed.
