Central venous catheters or "venous access devices" include totally implantable venous access devices or "ports," peripherally inserted central catheters, and tunneled lines. Venous access devices are now the standard of care in patients requiring long-term intravenous drug administration. Arm venous access device placement is a valuable option for vascular access yet often complicated or rendered practically impossible by the condition and size of peripheral veins. We describe a modification of the arm venous access device implantation technique that we use in our department in order to offer this option to our patients, regardless of their peripheral veins condition.
After ultrasound guided venous access of a suitable neck vein, we create a port pouch-in case of a totally implantable vascular access device-or a skin nick-in case of a venous access device-in the inner aspect of the mid-arm. Using a straight metal tunneler, we tunnel the line from the neck to the arm in two stages, externalizing and re-inserting the line into a skin nick made on the deltopectoral groove. We call this technique "Arm-to-Chest Tunneling" and use it to place venous access devices in the arm using a neck venous access.
The Arm-to-Chest Tunneling technique allows us to use larger arm venous access device catheters irrespective of the arm veins condition. Thus, this technique has the advantages of arm venous access device placement, with the added benefit of saving the arm veins.
The "Arm-to-Chest Tunneling" method offers the alternative to place a venous access device in a more discreet site in the arm, even in cases in which arm veins are inadequate.
中心静脉导管或“静脉通路装置”包括完全植入式静脉通路装置或“端口”、外周静脉穿刺中心静脉导管和隧道式导管。对于需要长期静脉给药的患者,静脉通路装置现已成为标准治疗手段。手臂静脉通路装置置入对于血管通路而言是一种有价值的选择,但外周静脉的状况和尺寸常常使其变得复杂或几乎无法实施。我们描述了一种手臂静脉通路装置植入技术的改良方法,我们科室采用该方法以便为患者提供这一选择,而不论其外周静脉状况如何。
在超声引导下经合适的颈部静脉建立通路后,我们在手臂中部内侧制作一个端口袋(用于完全植入式血管通路装置的情况)或一个皮肤切口(用于静脉通路装置的情况)。使用直的金属隧道器,分两个阶段将导管从颈部穿入手臂,先将导管引出,再重新插入三角肌胸大肌沟处的皮肤切口中。我们将此技术称为“臂至胸隧道技术”,并使用它通过颈部静脉通路在手臂置入静脉通路装置。
臂至胸隧道技术使我们能够使用更大的手臂静脉通路装置导管,而不论手臂静脉状况如何。因此,该技术具有手臂静脉通路装置置入的优点,还额外具有保护手臂静脉的益处。
“臂至胸隧道技术”提供了一种选择,即使在手臂静脉条件不佳的情况下,也能将静脉通路装置放置在手臂更隐蔽的部位。
