The purpose of this communication is to describe our preliminary experience with the Amplatzer Vascular Plug 4 (AVP 4) in peripheral vascular embolization. The AVP 4 was used for peripheral vascular embolization in five patients with renal pseudoaneurysm (n = 2), postsurgical peritoneal bleeding (n = 1), posttraumatic gluteal hemorrhage (n = 1), and intercostal pseudoaneurysm (n = 1). Occlusion time was recorded. Patients were followed up clinically and by imaging for 1 month after the procedure. All treated vessels or vascular abnormalities were successfully occluded within 3 min for low-flow circulation and over 8 min for high-flow circulation. At 1-month follow-up, all patients were symptom-free. All deployed devices remained in the original locations and desirable configurations. In conclusion, the AVP 4 seems to be safe and effective for occluding peripheral vessels and vascular abnormalities. Because of its compatibility with 0.038-in. catheters, it can be deployed through a diagnostic catheter following angiography without exchanging a sheath or guiding catheter. Compared with the previous generation of vascular plugs, the AVP 4 allows for faster procedure times and decreased exposure to radiation.
本交流旨在描述我们在周围血管栓塞中使用 Amplatzer 血管塞 4 （AVP 4）的初步经验。AVP 4 用于治疗 5 例患者的肾假性动脉瘤（n = 2）、手术后腹膜出血（n = 1）、创伤性臀肌出血（n = 1）和肋间假性动脉瘤（n = 1）。记录闭塞时间。在手术后 1 个月，对患者进行临床和影像学随访。所有治疗的血管或血管异常在低流量循环中 3 分钟内、高流量循环中 8 分钟内成功闭塞。在 1 个月的随访中，所有患者均无症状。所有部署的器械均保持在原始位置和理想状态。总之，AVP 4 似乎是安全有效的，可用于闭塞周围血管和血管异常。由于其与 0.038 英寸导管兼容，因此可以在血管造影后通过诊断导管进行部署，而无需更换护套或引导导管。与前一代血管塞相比，AVP 4 可以缩短手术时间，减少辐射暴露。
