Venous occlusion is not uncommon and total venous obstruction with more proximal patency may occur in as many as 10% of previous implants. Many techniques are available to obtain ipsilateral access; however, most require special equipment or skills. We describe a technique of infraclavicular cannulation of the brachiocephalic vein ipsilateral to the occlusion that is safe and feasible for most implanters.
Fourteen patients with subclavian/axillary occlusions ipsilateral to the implanted device and requiring revision or upgrade of their system or venous occlusion with contraindication to implant on the contralateral side underwent lead addition/placement via a brachiocephalic approach. Following venography, an 18-gauge needle was used to gain brachiocephalic access. The needle was initially positioned in a lateral infraclavicular location. The needle was then advanced under the clavicle in a horizontal plane and advanced toward the sternal notch under fluoroscopic guidance.
Fourteen patients underwent an attempt at brachiocephalic access. Cannulation of the brachiocephalic was possible in all 14 and lead(s) were successfully implanted in all. There were no complications with the procedure, specifically no pneumothoraces. In follow-up (mean 36 months, range 1-86 months), all implanted leads function well, with no evidence of lead failure or impedance changes.
A lateral infraclavicular approach is a safe and effective technique for obtaining brachiocephalic access when the subclavian/axillary vein is occluded. This technique is easy to learn and may be useful for implanters without the equipment or skills needed for lead extraction or microdissection or in cases where patients refuse these procedures.
静脉闭塞并不罕见,在既往植入物中,多达10%的患者可能出现更近端通畅的完全静脉阻塞。有多种技术可用于获得同侧通路;然而,大多数技术需要特殊设备或技能。我们描述了一种对大多数植入者来说安全可行的、用于闭塞同侧头臂静脉的锁骨下插管技术。
14例植入装置同侧锁骨下/腋静脉闭塞且需要对其系统进行翻修或升级,或因对侧植入有禁忌证而存在静脉闭塞的患者,通过头臂途径进行导线添加/放置。静脉造影后,使用18号针头获得头臂通路。针头最初置于锁骨下外侧位置。然后在锁骨下水平推进针头,并在透视引导下向胸骨切迹推进。
14例患者尝试进行头臂通路建立。14例患者均成功进行了头臂静脉插管,且所有患者均成功植入了导线。该操作无并发症,尤其是无气胸发生。在随访(平均36个月,范围1 - 86个月)中,所有植入的导线功能良好,无导线故障或阻抗变化的迹象。
当锁骨下/腋静脉闭塞时,锁骨下外侧入路是一种安全有效的获得头臂通路的技术。该技术易于学习,对于没有导线拔除或显微解剖所需设备或技能的植入者,或在患者拒绝这些操作的情况下可能有用。
