- Abstract
Introduction: Transcatheter arterial embolization is the first-line treatment for visceral artery pseudoaneurysms (VAPAs); however, the intraprocedural rupture of pseudoaneurysms is an important complication. The present study was performed to evaluate the safety of embolization for VAPAs, including the incidence of intraprocedural rupture. Methods: Among 56 consecutive patients with 57 VAPAs who underwent treatment between April 2009 and October 2020, 46 patients with 47 VAPAs underwent embolization. Complications related to embolization including intraprocedural rupture, the technical success rate, and clinical outcomes were evaluated. Complications that required extended hospitalization, an advanced level of care, or resulted in permanent adverse sequelae or death were classified as major complications, while the remainder were considered to be minor. Technical success was defined as the completion of embolization. Results: The intraprocedural rupture of pseudoaneurysms occurred in 3 out of 47 VAPAs treated with embolization (6%) and resulted in minor complications. One liver abscess requiring drainage was regarded as a major complication (2%). Focal infarction after embolization was observed as a minor complication in 20 cases. Complications occurred in 24 out of 47 cases (51%), comprising one major complication (2%) and 23 minor complications (48%). The technical success rate was 100% (47/47). Fifty-three out of 56 patients (95%) were alive in a median follow-up period of 18 months (range: 2 days-137 months). Conclusions: Embolization is safe and useful for the treatment of VAPAs; however, the intraprocedural rupture of pseudoaneurysms may occur, and, thus, care is needed during this procedure.
