Hemodialysis catheters are commonly placed in the major central vein for the purpose of dialysis. Coiling or looping of guidewire is a rare but reported complication of a central vascular catheter insertion. We report a case in which we encountered a rare complication of looping of the guidewire used for dialysis catheter placement and how we correctly diagnosed and repositioned it under ultrasound guidance. A 68-yearold man diagnosed with Carcinoma of Pyriform Fossa admitted in our ICU had Acute Renal Failure. An attempt to insertion of hemodialysis catheter in left internal jugular vein was made. Following successful puncture, the guide wire was threaded through needle. After five centimeter length of guide wire was threaded, resistance was felt and a loop of guidewire was visualized which was abutting the posterior wall of vein in out-of-plane view, creating a dual-point echogenicity. Under ultrasound guidance, we slowly pulled out the guidewire till the loop disappeared.The catheter was then inserted without repeat puncture of the vessel, thus preventing chance of thrombosis by repeated attempts. Real time USG guidance not only improves the success rates but also decreases the number of attempts and complications related to hemodialysis catheterization. Moreover, it benefits the patients by reducing the risks and discomforts of the procedure by reducing the duration of cannulation. The intelligent use of real-time ultrasound guidance in each step of the central venous catheterization is absolutely the need of the hour to prevent catastrophic yet preventable complications.
血液透析导管通常放置在主要的中心静脉中用于透析。导丝盘绕或成环是中心血管导管插入术一种罕见但有报道的并发症。我们报告了一例在透析导管放置过程中遇到导丝成环这一罕见并发症的病例,以及我们如何在超声引导下正确诊断并重新定位它。一名68岁诊断为梨状窝癌的男性入住我们的重症监护病房,并发急性肾衰竭。尝试在左颈内静脉插入血液透析导管。成功穿刺后,将导丝穿过针头。在穿入5厘米长的导丝后,感觉到阻力,并且在平面外视图中可见一个导丝环,它紧靠静脉后壁,产生双点回声。在超声引导下,我们缓慢拔出导丝直到环消失。然后在不重复穿刺血管的情况下插入导管,从而避免了因反复尝试而导致血栓形成的可能性。实时超声引导不仅提高了成功率,还减少了尝试次数以及与血液透析导管插入相关的并发症。此外,它通过缩短置管时间降低了手术风险和不适,从而使患者受益。在中心静脉导管插入术的每一步中明智地使用实时超声引导绝对是当下防止灾难性但可预防并发症的迫切需要。
