It is widely accepted to be a very safe and viable approach, with significantlyless incidence of major access-related complications compared to the transfemoral approach. Most interventional cardiol-ogists prefer performing the procedure at the right side of the patient.since the right radial access is more convenient for manipulating catheters and devices. In some cases, catheters can become entrapped looped/kinked during transradial catheterization in the brachial artery. Regular maneuvers and manipulations to disengage the catheter might be unsuccessful due tothe narrowdiameterof the artery. Wepresent two cases of coronary angiography complicated by right coronary catheter knotting and present a simple approach for their reduction in the brachial artery using the Amplatz GooseNeck Snare. Informed consents were obtained from both patients. The first case was a 50-year-old woman with serious aortic valve stenosis who was transferred to the catheter lab for coronary angiography priortothe valvereplacement. Afterconsiderabletorquing of the Judkins right coronary catheter (JR3.5) (Cordis Europa, Roden, Holland), the right coronary artery was engaged and standard views were acquired. Upon withdrawal of the JR3.5 catheter, resistance was encountered and a knot was noted in the brachial artery. The second case was a 71-year-old woman who was admitted for percutaneous coronary intervention due to exertional chest pain. Her subclavian and aorta vessels were noted to be very tortuous while the doctors were performing coronary artery angiography. On attempting intubation of the right coronary artery a knot was tied in the right brachial artery. In the above cases the same technique was used when standard attempts failed to resolve the knot. On fluoroscopy, the catheter was found entrapped and kinked on itself in the brachial segment (Figs. 1A and 2A). The guidewire couldn't be able to pass through the knot, and applying clockwise or anticlockwise rotation or gentle.  Fig.1. A. Kinked and looped 6-Fr JR3.5 catheter in the right brachial artery. B.

Thus, the catheter could not withdraw from the brachial artery using the regular maneuvers. The patients would undergo surgery if no effective method could solve the problem. However, we successfully retrieved the catheters by using the goose neck snare and the process was as follows. After right femoral artery puncture, a 6 French JR3.5 guiding catheter was used. Through the guiding catheter an Amplatz GooseNeck Snare (Microvena, St. Paul, MN) was passed and grasped the kinked catheter tip in the aorta arch. The entrapped catheter was then pulled simultaneously from the two ends under the help of the snare, and the looped catheter was straightened (Figs.1B and 2B). After releasing the snare (Figs. 1C and 2C), the kinked catheter was unraveled with a 0.35 inch guidewire and was successfully removed from the radial artery. In Case 1, no stenosis was found in the coronary artery after angiography examination. Aortic valve replacement and ascending aortic valvuloplasty were performed successfully one week later. In Case 2, after removal of the catheter, angiography was completed by the right femoral approach and results showed occlusion of the left anterior descending artery (LAD) and severe stenosis in both the left circumflex artery (LCX) and right coronary artery (RCA) (Fig. 2D and 2E). Percutaneous coronary interventions of the LAD and LCX were successfully performed using 4 drug eluting stents (Fig. 2F). Four days later, RCA intervention was successfully performed by the radial approach (Fig. 2G). The patient was discharged 2 days later. Minor looping of the coronary catheter is common during left heart catheterization and is usually the result of excessive torquing of the catheter, especially in a tortuous subclavian artery. It usually can be managed with gentle rotation in the opposite direction, and thus goes unnoticed without complications. Sometimes a guidewire can be advanced to the knot and with gentle traction of the catheter the wire may pass through and open the knot. However, more complex knots may rotate in the direction of torque adding further problems. This looped/kinked cathetercan getentrapped and may require surgery for retrieval. Furthermore, perforating the catheter is of risk if excessive force is used. A single case report has suggested that a second catheter through the contralateral femoral artery can facilitate manipulation of a kinked catheter [5]. The second catheter is passed alongside the knotted catheterand directedthrough the loop of the knot. The knot is then pulled back to the bifurcation of the aorta and moved gently to and fro enabling knot reduction. A further technique with W grabber device has also been described [6]. However, the above-mentioned techniques have their limitations in the form of dependence on significant knot laxity and would therefore not be successful in the case of tighter knots. There is a great advantage of the technique that we have described. In the two cases we used the Amplatz GooseNeck Snare, which has the advantage of being open and can fixate the catheter from the side easily. Closed snares would require passing the device over the free end of the catheter. To the best of our knowledge, there is only one similar case described previously [7], where the authors used an Amplatz GooseNeck Snare to remove an entrapped catheter in the radial artery. In the case of tight catheter knots that do not respondtostandard maneuvers,wewould recommendthe useof this safe and easily applied technique, saving the patient from unplanned surgical intervention. 这是我发表在INT J CARDIOL的一篇文章，导管打折的一种处理办法，供参考。 周聪（南方医科大附属小榄医院） 用到除了外科的最后一招，逆向套取，绝对行！看到孙主任说取出来了，像孙主任说的'最后把鞘管外导管剪断，穿刺股动脉，抓捕器拉至升主动脉，在大空间范围内，把折打开，从股动脉鞘管拉出。'既然套上拉到宽阔地方捋顺了，为啥不再送泥鳅导丝从原路返回？ 徐浩（上海市一） 看导管近心端位置，如果在升主或者锁骨下，穿刺股动脉抓捕器固定近心端，慢慢打开后拉直。有一次打折，近心端在锁骨下，穿刺股动脉抓捕器到锁骨下，解开了，慢慢来，不能急 林海龙（大连市中心医院） 手压往往压不住，不知导管远端是否在主动脉弓里，如不在怎么转也没用，看能否将管再送到主动脉弓，再转。管在主动脉弓才能固定住远端。实在不行，只好下套圈了 田恒松（平煤神马医疗集团总医院） 手机没电了，穿刺左挠动脉，已成功退出，谢谢各位专家，回头视频发过去，谢谢大家！ 王海昌（唐都医院）      张涛（泊头市医院） 多见于锁骨下及头臂干扭曲的病人。力臂变了，再者术者没有看压力曲线 一般打折前压力曲线就有表现了。反方向转直，拉出。 田恒松（平煤神马集团总医院）  刚才穿刺左挠动脉用抓扑器的过程，患者冠脉造影无异常，谢谢王主任和各位专家！ 2017 鸡 年 大 吉 HAPPY NEW YEAR Drking 新春大礼包 震撼你的小心脏 俱乐部专场会议提要 王海昌介入并发症俱乐部 请根据手机系统扫描下列二维码，下载安装DrKing 苹果IOS系统 安卓系统 |
