Modified Blalock-Taussig shunts are usually clamped during the successive corrective or palliative surgical procedures carried out to treat underlying congenital heart disease, though at times they may be left permeable for a number of reasons. Subsequently, when this is no longer considered necessary and closure is indicated, the method of choice is percutaneous embolization using various coils or other devices. We report on a series of patients in whom this type of shunt was closed successfully via an arterial approach using a new device: the Amplatzer Vascular Plug. In addition to employing a controlled-release system, this type of plug has the advantage that it can be implanted using low-profile catheters. The patients were 1, 4 and 23 years old, respectively, and no complications were reported. The fluoroscopy time was 10, 11 and 9 minutes, respectively, and patients were followed up for 42 months.
改良的 Blalock-Taussig 分流术通常在为治疗潜在先天性心脏病而进行的连续矫正或姑息性手术过程中被夹闭，但有时出于多种原因，它们可能会保持通畅。随后，当不再需要时，且需要关闭分流术时，首选的方法是使用各种线圈或其他设备进行经皮栓塞。我们报告了一系列患者，他们通过动脉入路成功地使用一种新型装置：即 Amplatzer 血管塞来关闭这种类型的分流术。除了采用控制释放系统外，这种类型的塞子还有一个优点，即可以使用小口径导管进行植入。这 3 名患者的年龄分别为 1 岁、4 岁和 23 岁，均未发生并发症。透视时间分别为 10 分钟、11 分钟和 9 分钟，随访时间为 42 个月。
