To present the early clinical experience of a new mechanically controlled-release embolization device--the interlocking detachable coil (IDC)--in complex embolization outside the head.
IDCs were used only when conventional embolization techniques were considered too risky or unsafe. The coils consist of unfibered coiled platinum (0.012 inch), mechanically connected to a pusher wire and deployed through a Tracker 18 catheter. IDCs come in a range of diameters (2-8 mm) and lengths (1-30 cm).
A total of 87 IDCs were used for 27 procedures in 25 patients (mean 14.5 years) to occlude 31 arteries or vascular lesions. Control of the coil and its release were satisfactory and all coils ere fully retrievable up to the point of deployment. Two IDC coils embolized inadvertently but were retrieved; there were no other complications. The IDC coils could not be satisfactorily placed one high-flow arteriovenous (AV) fistula, and in another case there was a small residual fistula. Occlusion was produced in 29 of 31 lesions. Ancillary techniques were needed in 5 patients: temporary balloon occlusion in 2 and 0.038-inch coils in 3.
The IDC coil is an effective device that allows controlled embolization to be performed, especially in aneurysms and in high-flow AV fistulas in children.
介绍一种新型机械控制释放栓塞装置——可锁定分离线圈（IDC）在头部以外复杂栓塞中的早期临床经验。
仅在认为传统栓塞技术风险过高或不安全时才使用IDC。这些线圈由未纤维化的盘绕铂丝（0.012英寸）组成，通过机械方式连接到推送导丝，并通过Tracker 18导管进行释放。IDC有多种直径（2 - 8毫米）和长度（1 - 30厘米）可供选择。
共对25例患者（平均年龄14.5岁）进行了27次操作，使用了87个IDC来闭塞31条动脉或血管病变。线圈的控制及其释放效果令人满意，并且在释放前所有线圈均可完全回收。有两个IDC线圈意外栓塞，但已被回收；未出现其他并发症。在一处高流量动静脉（AV）瘘中，IDC线圈无法令人满意地放置，在另一例中存在小的残余瘘。31处病变中有29处实现了闭塞。5例患者需要辅助技术：2例采用临时球囊闭塞，3例采用0.038英寸的线圈。
IDC线圈是一种有效的装置，可实现可控栓塞，尤其适用于儿童的动脉瘤和高流量AV瘘。
