Standard Gianturco and "mini" coils cannot be used with some of the present microcatheter systems. However, occasions arise in which metallic coils would be an ideal embolic agent in vascular structure accessible only to a tracker (2.2-French) catheter system. We performed nine embolization procedures in eight patients with arteriovenous fistulas using platinum coils as an embolic agent. Fistulas were completely occluded in six of the nine cases. In several cases, platinum wire embolization was augmented with other agents. Complications occurred in two cases, neither resulting in permanent neurologic deficits. Advantages of using platinum coils included availability, radioopacity, thrombogenicity, biocompatibility, and delivery through microcatheters, specifically the tracker catheter system.
标准的 Gianturco 线圈和“微型”线圈不能与目前的一些微导管系统配合使用。然而，在某些情况下，金属线圈对于仅能通过追踪型（2.2 法国规格）导管系统进入的血管结构来说，将是一种理想的栓塞剂。我们对 8 例患有动静脉瘘的患者进行了 9 次栓塞手术，使用铂线圈作为栓塞剂。9 例中有 6 例瘘管完全闭塞。在几例病例中，铂丝栓塞与其他药物联合使用。发生了 2 例并发症，但均未导致永久性神经功能缺损。使用铂线圈的优点包括可用性、不透射线、致血栓性、生物相容性以及可通过微导管输送，特别是追踪型导管系统。
