Abstract

Purpose: To analyze the results from using endovascular techniques to place long-term chemotherapy catheters when advancing the catheter using the external jugular vein is difficult due to obstructions or kinking.

Methods: Between July 1997 and August 2000, 320 long-term chemotherapy catheters were placed, and in 220 cases the external jugular vein was used as the primary venous approach. In 18 of these patients, correct positioning was not achieved and several endovascular techniques were then utilized to overcome these obstacles, including manipulation of a J-wire with a moveable core, venography, and the exchange wire technique.

Results: In 94.5% of the patients with difficulties in obtaining the correct positioning, we were able to advance the long-term catheter to the desired position with the assistance of endovascular techniques.

Conclusions: Venography and endovascular guidance techniques are useful for the placement of long-term catheters in the external jugular vein.

放置长期化疗导管的血管内技术。

目的:分析经颈外静脉推进导管因阻塞或扭结困难时，应用血管内技术放置长期化疗导管的效果。方法:1997年7月至2000年8月，对320例患者进行长期化疗置管，其中220例以颈外静脉为主要静脉入路。在其中18例患者中，没有实现正确的定位，随后使用了几种血管内技术来克服这些障碍，包括操作带有可移动核心的j型钢丝、静脉造影术和交换钢丝技术。结果:在94.5%难以获得正确定位的患者中，我们能够在血管内技术的帮助下将长期导管推进到所需的位置。结论:静脉造影和血管内引导技术对颈外静脉长期置管是有用的。
