摘要
目的探讨床旁彩色多普勒超声在诊断小腿肌间深静脉丛血栓中的应用。方法 2010年1月～2012年6月,选择住ICU的患者120例为研究对象,采用床旁彩色多普勒观察患者小腿肌间深静脉丛血管管腔、血流情况,根据是否存在血栓形成分为病例组和对照组,再根据长期卧床、急性创伤和外科手术每组分为三个亚组,比较不同亚族血栓患病率及小腿肌间深静脉丛最大管径。结果 12例患者查出小腿肌间深静脉丛血栓形成为病例组,107例患者未见异常为对照组。12例患者均为急性血栓,二维超声见血管内低回声,部分阻塞患者血管呈充盈缺损,彩色多普勒显示完全阻塞的患者血管无血流信号。长期卧床、手术后及急性创伤患者之间小腿肌间深静脉丛血栓发生率及小腿肌间深静脉丛最大管径比较,差异均有高度统计学意义(P<0.01)。抗凝治疗1周～1个月进行复查,8条血管完全通畅,24条血管内的血栓回声增强、血栓变小,部分再通;2例血栓无明显变化。总有效率为94.1%。结论采用床旁彩色多普勒超声对ICU重症患者小腿肌间静脉进行探查,能够及时发现血栓形成,及时治疗。
Objective To discuss application of bedside color doppler ultrasound on diagnosis of crus muscle between deep vein plexus thrombosis. Methods Jan 2010-Jun 2012,120 cases were selected in ICU as subject. Bedside color Doppler ultrasound was used to detect crus muscle between deep vein lumen,blood flow. The eases were divided into illness group and control group according to thrombopoiesis. They were divided by long-term bed,acute trauma and surgery. Thrombus prevalence and crus muscle between deep venous plexus maximum diameter were compared in 3 subgroup. Results Twelve cases showed crus muscle between deep vein plexus thrombosis,as illness group, and 107 cases showed normal, as control group. All of the plexus were acute, Two dimensional ultrasound showed Intravascular low echo, part of the patients with vascular obstruction is filling defect. Color Doppler display completely blocked blood vessels of patients without blood flow signal. Thrombus prevalence and crus muscle between deep venous plexus maxi- mum diameter had significant difference in 3 subgroups （P 〈 0.01 ）. After therapy,eight vascular completely open,24 intravascular thrombosis acoustic enhancement,2 cases of thrombosis has no obvious change. Total effective rate was 94.1%. Conclusion bedside color doppler ultrasound on diagnosis of crus muscle between deep vein plexus thrombosis in ICU,can timely find thrombosis,timely treatment.
