The aim of this study was to evaluate the effectiveness of the new Amplatzer vascular plug (AVP) for the occlusion of vascular abnormalities and peripheral vessels, especially those with a large diameter.
The new device was used for the occlusion of five internal iliac arteries to prevent retrograde endoleak following endograft repair, three left subclavian arteries for the treatment of type II endoleaks after positioning thoracic aorta stent-grafts, one pulmonary arteriovenous malformation, one haemodialysis fistula in a patient with forearm oedema and one large gastric varix in a patient who had undergone transjugular intrahepatic portosystemic shunt (TIPS) for haemorrhage.
The five internal iliac arteries and the three left subclavian arteries were successfully occluded within 8 and 5 min, respectively. The pulmonary arteriovenous fistula was closed within 3 min and percutaneous oxygen saturation rose from 73% to 93%. The haemodialysis fistula was closed with one device within 4 min. The gastric varix was embolised with two AVPs and two coils within 12 min.
The AVP is an effective device for occluding large diameter vascular abnormalities and peripheral vessels. It is inexpensive and enables safe and low-risk embolisation, with saving of time and requiring only low X-ray dose.
本研究旨在评估新型Amplatzer血管封堵器（AVP）封堵血管异常和外周血管，尤其是大直径血管的有效性。
使用该新型装置封堵5条髂内动脉以预防腔内修复术后逆行性内漏，封堵3条左锁骨下动脉以治疗胸主动脉覆膜支架置入术后的Ⅱ型内漏，封堵1例肺动静脉畸形，封堵1例因前臂水肿而行血液透析造瘘术患者的动静脉内瘘，以及封堵1例因出血而行经颈静脉肝内门体分流术（TIPS）患者的巨大胃静脉曲张。
5条髂内动脉和3条左锁骨下动脉分别在8分钟和5分钟内成功封堵。肺动静脉瘘在3分钟内闭合，经皮血氧饱和度从73%升至93%。血液透析动静脉内瘘用1个装置在4分钟内闭合。胃静脉曲张用2个AVP和2个弹簧圈在12分钟内栓塞。
AVP是封堵大直径血管异常和外周血管的有效装置。它价格低廉，能实现安全、低风险的栓塞，节省时间且仅需低剂量X线照射。
