床旁彩色多普勒超声在ICU患者小腿肌间深静脉血栓诊疗中的应用

Diagnostic value of hand-carried color doppler ultrasound in calf muscular venous thrombosis in ICU

目的探讨床旁彩色多普勒超声诊断ICU患者小腿肌间静脉丛血栓的临床价值。方法应用床旁彩色多普勒超声技术观察106例ICU患者小腿肌间深静脉丛管腔、血流、血栓形成及治疗后血栓再通情况。结果 ICU住院超过7d的无症状和/或局部轻度症状的危重患者小腿肌间静脉血栓检出率达10.38%,长期卧床、急性创伤及外科手术的ICU患者小腿肌间深静脉血栓发生率依次递减,抗凝治疗有效率达93.93%,治疗性诊断与床旁彩色多普勒超声诊断率接近。结论对无临床症状和/或局部轻度症状ICU高危患者,可常规进行床旁彩色多普勒超声检查。

Objective To explore the clinical applicated value in diagnosis of calf muscular venous thrombosis with hand-carried Color Doppler Ultrasound（ CDU）in Intensive Care Unit（ICU）. Methods Application of hand-carried CDU of deep venous plexus lumen, blood flow, thrombosis and reeanalization of thrombus after treatment of the calf muscle of 106 ICU patients was observed. Results Of ICU hospitalized for more than 7d without symptoms and / or with mild local symptoms, calf muscle venous thrombosis detection rate was 10. 38%. In prolonged bed rest, acute trauma and surgical ICU patients, calf muscular ve- nous thrombosis rates were decreasing, the effective rate of 93.93% after anticoagulant therapy, treatment diagnosis rate was close to CDU. Conclusion ICU patients without clinical symptoms and / or with mild local symptoms may be routine bedside hand-carried CDU.
