摘要
目的探讨彩超检查在肿瘤患者PICC术后上肢静脉血栓的诊断价值。方法回顾性分析102例肿瘤患者中PICC术后发生上肢静脉血栓的超声表现及治疗后的超声表现。结果 102例中75例可清晰显示导管沿静脉走行方向呈平行管状回声,血流充盈良好,血流频谱未见异常;27例可见不同部位静脉内径增宽,管腔内导管周围可见低回声充填,血流束窄或稀少,甚至无血流显示。结论恶性肿瘤患者PICC管置入术后血栓形成是其主要的并发症,彩超检查具有高准确性、高敏感性、无创伤性、无禁忌症、可重复性及费用相对低廉等优点,对恶性肿瘤患者化疗期间PICC置入术后血栓的诊断及治疗效果的评估有一定价值,值得临床广泛使用。
Objective To evaluate the value of color Doppler ultrasound in the diagnosis of upper extremity venous thrombosis in patients with tumors after operation of PICC. Methods Data of ultrasonic images and clinical diagnosis were retrospectively analyzed on102 patients with tumors, whose upper veins were taken operation of PICC and then developed into thrombosis. Results Among 102 cases,75 cases clearly showed that the catheter along veins direction presented parallel tubular echo, blood flowed good, blood flow spectrum did not show abnormity; 27 cases showed that the inner diameter of different parts of vein was widened, lumen catheter surrounded by hypoecho,bloodstream was narrow or rare, even without blood flow display. Conclusions Upper extremity venous thrombosis is the main complication of malignant tumor patients after operation of PICC, color Doppler ultrasound examination has high accuracy, high sensibility,noninvasion, no contraindication, repeatability and low cost. It also has a certain value in evaluating the diagnosis and treatment effect of thrombosis after implantation of the PICC during chemotherapy in patients with malignant tumors, which deserves promotion in clinic.
