摘要
目的探讨高频彩色多普勒超声(彩超)对中心静脉置管(PICC)术后静脉血栓形成的诊断价值,并对血栓形成的相关因素进行分析。方法连续收集广州市第一人民医院超声科2016年6月至12月PICC术后拟诊静脉血栓形成而接受高频彩超检查的83例患者。使用美国GE Vivid E9超声诊断仪高频探头对PICC置管部位及其相邻的近远段血管进行探查,对血栓检出情况及患者的相关资料(性别、年龄、基础疾病、置管时长、置管途径)进行回顾性分析。结果 50例(60.2%)患者PICC置管部位或邻近静脉高频彩超检查发现血栓。置管后2周内血栓检出率(64.0%)高于2周以上(36.0%),但差异无统计学意义(χ~2=0.74,P>0.05)。50岁以上脑血管意外和恶性肿瘤患者的血栓检出率(64.0%)高于其他患者(36.0%),差异有统计学意义(χ~2=5.97,P<0.05)。结论高频彩超对诊断PICC相关静脉血栓形成有重要价值;PICC术后2周内可能是静脉血栓形成的高发期,50岁以上的脑血管意外和恶性肿瘤患者是PICC术后血栓发生的高危人群,建议对此类患者及时进行高频彩超检查,以利早期诊断、治疗。
Objective To investigate the diagnostic value of high frequency color Doppler ultrasonography in venous thrombosis associated with peripherally inserted central catheters （PICC）, and to analyze the risk factors related to thrombosis.Methods A total of 83 patients were consecutively collected, who were suspected to be afflicted with venous thrombosis following PICC and underwent the examinaiton of color Doppler uhrasonography between June and December 2016, in Guangzhou First Municipal People＇s Hospital.All the PICC-related veins were observed using GE Vivid E9 ultrasonic diagnostic equipment with high frequency probe.Clinical data of all cases （sex,age,underlying disease,duration and site of catheterization） and the detection of thrombus were retrospectively analysed. Results Thrombus was detected by high frequency color Doppler uhrasonography in PICC-related veins in 50 （60.2%） cases.The rate of thrombus detection （ 64.0% ） within 2 weeks of venous catheterization was higher than that over 2 weeks （ 36.0% ）, but the difference was not statistically significant （ X2 = 0.74, P 〉 0.05 ）. Thrombus was found more often in patients over 50 years old with cerebrovascular accident and malignant tumor （64.0%） , compared with that in other patients （36.0%, X2= 5.97, P 〈0.05）.Conclusions High frequency color Doppler ultrasonography has important diagnostic value for PICC-related venous thrombosis. The thrombosis may occur more often within 2 weeks of PICC catheterization.Patients over 50 years old with cerebrovascular accident and malignant tumor are at higher risk of venous thrombosis following PICC, and are suggested to receive color Doppler uhrasonography timely with the aim of early diagnosis and treatment.
