经外周静脉置入中心静脉导管后相关性深静脉血栓形成研究进展

Research progress of deep venous thrombosis after peripherally inserted central venous catheter

系统研究关于经外周静脉置入中心静脉导管相关深静脉血栓(peripherally inserted central catheter-related deep vein thrombosis,PICC-DVT)的文献,对其危险因素、临床体征、诊断、治疗、预防加以总结。PICC-DVT的形成受患者、导管、操作者相关危险因素的影响。超声检查是其诊断的最常用的方法,静脉造影是对超声不能确诊的补充。低分子量肝素作为其治疗方法至少需要使用3个月。但目前关于PICC-DVT的预防仍不成熟,需待完善。总结后发现PICC-DVT在临床上是常见的,现有的研究可以为其诊断、治疗、预防提供指导。

A systematic review of the literature on peripherally inserted central catheter-related deep vein thrombosis (PICC-DVT) through peripheral venous catheterization,summarized its risk factors,clinical signs,diagnosis,treatment,and prevention.Studies have found that the formation of PICC-DVT is affected by patient-,catheter-,and operator-related risk factors.Ultrasound is the most commonly used method for diagnosis,and venography is a supplement to the inconclusive diagnosis of ultrasound.Low-molecular-weight heparin needs to be used as a treatment for at least 3 months.However,the prevention of PICC-DVT is still immature and needs to be improved.After summary,we found that PICC-DVT is common in the clinic,and existing research can provide guidance for its diagnosis,treatment,and prevention.
