摘要

本研究描述了在标准长度冠状动脉导丝上交换过线(OTW)血管成形术导管的替代方法。使用特殊设计的导管剥离器Jaws (Microvena, White Bear Lake, MN)进行交换。Jaws是一种一次性器械,类似于电工的剥线器,其切割刀片在切割导管轴之前自动将导线居中。93例患者进行了170例导管更换。拔管成功率为99%,再插入成功率为98%。将导管拔出至金属丝近端,在止血阀附近横切导管轴。所有的导管均通过2 - 3个切口拔出。导管移除后,另一个OTW、滑轨、定向动脉粥样硬化切除术、Cook或J&J支架可以在标准的175厘米钢丝上引入。在那些无法预见导管重复使用的情况下,Jaws交换为操作者提供了全范围的导管选择,使用标准长度的血管成形术导丝既方便又经济。

Jaws catheter exchange: an alternative method of exchanging coronary interventional devices.

This study describes an alternative method of exchanging over-the-wire (OTW) angioplasty catheters over standard length coronary guide wires. Exchange was facilitated with a specially designed catheter stripper, Jaws (Microvena, White Bear Lake, MN). Jaws is a disposable instrument similar to an electrician's wire stripper whose cutting blades automatically center the wire before cutting the catheter shaft. One hundred seventy catheter exchanges were performed in 93 patients. Catheter extraction success was 99% and reinsertion success was 98%. Catheters were extracted by withdrawing the catheter to the proximal end of the wire and transecting the catheter shaft near the hemostatic valve. All catheters were extracted with two to three cuts. After catheters removal, another OTW, sliding rail, directional atherectomy, Cook, or J&J stent could be introduced over the standard 175 cm wire. In those situations where catheter reuse is unanticipated, Jaws exchange affords the operator a full range of catheter choices with the convenience and economy of using a standard length angioplasty guide wire.
