深静脉血栓患者磁共振分型与经股静脉穿刺置管碎栓和溶栓手术复通效果的关系分析

Analysis of the relationship between 3.0T MRI classification and the recanalization effect of breaking thrombosis/thrombolysis surgery through indwelling catheter via femoral vein puncture for patients with DVT

目的:分析深静脉血栓(DVT)患者磁共振成像(MRI)分型与数字减影血管造影技术(DSA)下经股静脉穿刺置管碎栓和溶栓复通效果的关系。方法:选取医院收治的80例DVT患者,均行MRI扫描检查,分析患者MRI分型急性期、亚急性期和慢性期的不同发病期,采用DSA下经股静脉穿刺置管干预治疗;采用logistics回归模型分析MRI分型与患者血管再通关系。结果:80例患者MRI分型中急性33例,亚急性29例,慢性18例。急性期、亚急性期及慢性期患者血管再通满意时间差异有统计学意义(F=4.832,P<0.05),其中急性期患者再通满意时间最低,慢性期再通满意时间最高。急性期、亚急性期及慢性期患者血管再通效果差异有统计学意义(x2=8.332,P<0.05),其中急性期血管再通效果最佳,慢性期最差。DVT患者MRI分型是影响溶栓复通效果的独立性影响因素(OR=1.906,P<0.05)。结论:DVT患者MRI分型是影响溶栓复通效果的独立性影响因素。

Objective:To analyze the relationship between magnetic resonance imaging(MRI)classification and the recanalization effect of breaking thrombosis/thrombolysis surgery through indwelling catheter via femoral vein puncture under digital subtraction angiography(DSA)for patients with deep venous thrombosis(DVT).Methods:80 patients with DVT admitted to hospital were selected as the research subjects,and all of them underwent MRI scans.The different diseased periods of patients in MRI classification included acute stage,subacute stage and chronic stage were analyzed.And the interventional treatment of indwelling catheter via femoral vein puncture under DSA was adopted.And logistics regression model was adopted to analyze the recanalization relationship between MRI classification and the vascular recanalization of patients.Results:Among the MRI classification of 80 patients,33 cases were acute DVT,29 cases were subacute DVT,and 18 cases were chronic DVT.The difference of the time of the satisfaction of vascular recanalization among patients with acute,subacute and chronic phases were significant(F=4.832,P<0.05).Among of them,the time of the satisfaction of vascular recanalization of patients with acute DVT was the lowest,and that of patients with chronic DVT was the highest.The difference of the vascular recanalization effect among patients with acute DVT,with subacute DVT and with chronic DVT was significant(x2=8.332,P<0.05).And the vascular recanalization effect of patients who were at acute DVT stage was the best,while that of patients who were at chronic DVT stage was the worst.The MRI classification of patients with DVT was the independent influencing factor that affected the recanalization effect of thrombolysis(OR=1.906,P<0.05).Conclusion:The MRI classification of patients with DVT is the independent influencing factor that affects the recanalization effect of thrombolysis.
