高频彩超对肿瘤化疗患者PICC插管后血栓形成的诊断价值

Diagnostic Value of Color Doppler Ultrasound For Venous Thrombosis After PICC Catheter in Tumor Patients with Chemotherapy

目的研究高频彩超检查对于肿瘤化疗患者经外周静脉置入中心静脉导管(PICC)插管后静脉血栓形成的诊断价值。方法选取32例肿瘤化疗行PICC后形成静脉血栓患者作为研究对象,回顾分析其彩超诊断情况和治疗后超声图像表现。结果 32例患者中,26例静脉附壁血栓,6例完全型静脉血栓;彩超图像可见静脉内径增宽,导管周围存在低回声,CDFI显示血流束稀少、狭窄甚至无血流信号。结论高频彩超检查对于肿瘤化疗患者PICC插管后静脉血栓形成的诊断具有敏感性高、无创伤及可重复等优点,对于静脉血栓的预防、快速诊断及治疗具有重要指导意义。

Objective To study the diagnostic value of color doppler ultrasound for venous thrombosis after PICC catheter in tumor patients with chemotherapy. Methods 32 cases of tumor patients with chemotherapy,whose venous thrombosis were taken after PICC catheter were collected as the subject investigated, the ultra- sound diagnostic and performance ultrasound images after treatment were analyzed retrospectively. Results In the 32 patients, 26 cases with venous thrombus, 6 cases with complete venous thrombosis; endoscopic ultrasound image visible vein widened, there was a low echo around the catheter, CDFI showed that blood flow beam rare, narrow or no blood flow. Conclusion The color doppler ultrasound has the several advantages such as high sen- sitivity, non - invasive and can be repeated, etc., for the diagnosis of venous thrombosis after PICC catheter in tumor patients with chemotherapy, it has important guiding significance for the prevention, rapid diagnosis and treatment of venous thrombosis.
