Although the use of central venous silicone catheters is widespread, little is known about the incidence of catheter rupture and embolization. Over a three-year period, 3916 silicone catheters were inserted in 3672 patients in the authors' hospital. Catheter or catheter fragments embolism occurred in 4 patients (1.2 embolizations per 1000 patients treated). Inappropriate mechanical deobstruction attempts resulted in 2 embolizations, and hence, these should be avoided. Chest roentgenography failed to detect the small fragments within the heart silhouette in 2 cases. Two-dimensional echocardiography showed the separated catheter fragment in all 4 cases. All four catheter fragments were subsequently removed from the right-heart chambers.
尽管中心静脉硅胶导管的使用很广泛，但对于导管破裂和栓塞的发生率却知之甚少。在三年时间里，作者所在医院的3672例患者中插入了3916根硅胶导管。4例患者发生了导管或导管碎片栓塞（每1000例接受治疗的患者中有1.2例栓塞）。不恰当的机械疏通尝试导致了2例栓塞，因此应避免此类操作。胸部X线检查未能在2例患者中检测到心脏轮廓内的小碎片。二维超声心动图在所有4例中均显示出分离的导管碎片。随后，所有4个导管碎片均从右心腔中取出。
