摘要
目的探讨彩色多普勒超声对颈内静脉置管后附管血栓形成的诊断价值。方法对行颈内静脉置管术的251例患者的颈内静脉分别进行术前及术后彩色多普勒超声检查,确诊附管血栓形成的患者观察其血管内膜是否光滑,导管壁是否规整及血栓形成的部位、大小、形态、血流通过情况。采用彩色多普勒超声评价血栓分级情况并定期随访其中57例,观察血栓变化情况。结果 251例患者中,共检出附管血栓形成113例,阳性率为45.02%。所形成的血栓以Ⅱ级为主,其中9例颈内静脉面积狭窄率超过50%,为Ⅲ级血栓。随访患者经溶栓处理后原附管血栓全部消失,最终拔管处理。结论对颈内静脉置管术后患者采用彩色多普勒超声检查,能早期发现附管血栓并可以指导临床及时处理。
Objectives To explore the value of color Doppler ultrasound in diagnosis of thrombosis after jugular vein catheterization. Methods Totally 251 patients were examined by color Doppler ultrasound before and after jugular vein catheterization in this study. Smooth degree of the inner venous walls in patients with thrombosis after jugular vein catheterization was detected, and the location, size, profile and venous canalization of the thrombosis were evaluated.All the cases with thrombosis were graded and 57 cases were regularly followed up to detect the change of the thrombosis. Results There were 113 patients with thrombosis after catheterization, the positive rate was 45.02%. They were mainly grade II thrombosis, and 9 cases were grade III with a stenosis rate50%. All the thrombosis vanished after thrombolysis in the follow-up group and the patients were extubated finally. Conclusions Thrombosis after catheterization in jugular vein can be found in its early stage by using color Doppler sonography and treated in time.
