Between July 1980 and July 1983, we occluded 30 pulmonary arteriovenous fistulas (PAVFs) in four patients by percutaneous placement of coil springs. All patients had significant right-to-left shunts and hypoxemia. One presented with recurrent cerebral abscesses following bilateral thoracotomy and lobectomy. The technique requires advancement of the catheter superselectively into the feeding artery just proximal to the fistula. Occlusion at this site preserves the maximum amount of functioning pulmonary parenchyma. Frequently more than one coil spring is required for occlusion. In our experience, the coil spring is a safe, effective, economical vaso-occlusive device for management of PAVFs.
1980年7月至1983年7月期间，我们通过经皮放置弹簧圈封堵了4例患者的30处肺动静脉瘘（PAVF）。所有患者均有明显的右向左分流和低氧血症。其中1例患者在双侧开胸手术和肺叶切除术后出现复发性脑脓肿。该技术需要将导管超选择性推进到瘘口近端的供血动脉中。在此部位封堵可保留最大量的有功能的肺实质。封堵通常需要不止一个弹簧圈。根据我们的经验，弹簧圈是一种安全、有效且经济的血管闭塞装置，用于治疗肺动静脉瘘。
