Visceral artery pseudoaneurysms (VAPAs) are uncommon in clinical practice but may have serious clinical outcomes up to death. Endovascular management is a safe effective alternative option to traditional surgical procedures. This study assesses the outcome of different embolic materials and techniques used in the endovascular management of VAPAs. This is a two-center retrospective analysis of endovascular embolisation of 46 VAPAs, with a mean pseudoaneurysm size of 13 ± 11.35 mm, that were urgently managed between July 2018 and March 2020. Patients’ presentations were GIT hemorrhage, intrabdominal hemorrhage, hematuria, and abdominal pain in 34.78%, 30.43%, 23.91%, and 10.87% respectively. Management using coils only was done in 28/46 patients (60.87%), NBCA glue only in 16/46 patients (34.78%), combined coils and NBCA glue in 1/46 patient (2.17%), and Amplatzer plugs only in 1 patient (2.17%). The management techniques were sac packing in 9/46 patients (19.57%), inflow occlusion in 28/46 patients (60.87%) and trapping in 9/46 patients (19.57%). All patients were followed-up for 1 year after the procedure. The overall clinical success and periprocedural complication rates were 93.48%, and 15.22% respectively, and 30-day mortality was zero. Clinical success was 92.86% in the coil subgroup (n = 28), and 93.75% in the NBCA glue subgroup (n = 16). The technical success rate was 100%. Effectiveness of the procedures during the follow-up was 97.83%. Target lesion re-intervention rate was 2.17%. Transarterial embolisation can provide high technical and clinical success rates with low periprocedural complication and re-intervention rates, as well as satisfactory procedure effectiveness in the management of VAPAs.

血管内栓塞结果分析：46例内脏动脉假性动脉瘤的横断面双中心研究

内脏动脉假性动脉瘤 (VAPA) 在临床实践中并不常见，但可能会导致严重的临床结果直至死亡。血管内治疗是传统外科手术的一种安全有效的替代选择。本研究评估了用于 VAPA 血管内治疗的不同栓塞材料和技术的结果。这是对 2018 年 7 月至 2020 年 3 月期间紧急处理的 46 例 VAPA 血管内栓塞术的双中心回顾性分析，平均假性动脉瘤大小为 13 ± 11.35 mm。患者的表现是 GIT 出血、腹腔内出血、血尿和腹痛分别占 34.78%、30.43%、23.91% 和 10.87%。28/46 患者（60.87%）仅使用线圈进行管理，16/46 患者（34.78%）仅使用 NBCA 胶，1/46 患者（2.17%）仅使用线圈和 NBCA 胶，和 Amplatzer 仅在 1 名患者中插入 (2.17%)。管理技术为 9/46 例患者（19.57%）的囊填充，28/46 例患者（60.87%）的流入阻塞和 9/46 例患者（19.57%）的截留术。所有患者术后均随访1年。总体临床成功率和围手术期并发症率分别为 93.48% 和 15.22%，30 天死亡率为零。线圈亚组 (n = 28) 的临床成功率为 92.86%，NBCA 胶水亚组 (n = 16) 的临床成功率为 93.75%。技术成功率为100%。随访期间手术有效率为97.83%。目标病灶再干预率为2.17%。经动脉栓塞术可以提供高技术和临床成功率，围手术期并发症和再干预率低，
