This study was performed to evaluate the safety and efficacy of endovascular stenting and embolization for the management of radiation-induced peripheral arterial pseudoaneurysms.
Twelve consecutive patients with radiation-induced peripheral arterial pseudoaneurysms (diameter of 10-30 mm and mean size of 20.42 mm) were admitted to our hospital from 1 January 2015 to 31 October 2019. The patients' baseline characteristics, perioperative parameters, device characteristics, and curative effects were systematically recorded and analyzed.
The 12 patients comprised 3 men and 9 women with a mean age of 62.90 ± 13.97 years. The iliac artery was the most commonly involved artery, followed by the subclavian artery. In all patients, the pseudoaneurysms were detected by enhanced computed tomography. Twelve covered stents were deployed (7 or 8 mm in diameter and 50 mm in length). Additional coil embolization was performed in three patients (Patients 8, 9, and 10). The primary and secondary technical success rate was 91.7% and 100%, respectively. Apart from one death caused by rebleeding, no patients developed rebleeding during follow-up.
Endovascular stenting and coil embolization are feasible and effective for the management of radiation-induced peripheral arterial pseudoaneurysms in highly selected patients.
本研究旨在评估血管内支架置入和栓塞治疗放射性外周动脉假性动脉瘤的安全性和疗效。
2015 年 1 月 1 日至 2019 年 10 月 31 日，我院收治了 12 例放射性外周动脉假性动脉瘤患者（直径 10-30mm，平均直径 20.42mm）。系统记录并分析了患者的基线特征、围手术期参数、器械特征和疗效。
12 例患者中，男 3 例，女 9 例，平均年龄 62.90±13.97 岁。最常受累的动脉是髂动脉，其次是锁骨下动脉。所有患者均通过增强 CT 检测到假性动脉瘤。共植入 12 枚覆膜支架（直径 7 或 8mm，长度 50mm）。3 例患者（患者 8、9 和 10）进行了额外的线圈栓塞。主要和次要技术成功率分别为 91.7%和 100%。除 1 例因再出血死亡外，无患者在随访期间发生再出血。
对于高度选择的患者，血管内支架置入和线圈栓塞治疗放射性外周动脉假性动脉瘤是可行且有效的。
