改良阻断浅静脉回流装置在下肢深静脉血栓溶栓治疗中的应用研究
Study on application of modified superficial venous reflux occlusion device in thrombolytic therapy for lower extremity deep venous thrombosis
摘要
Abstract
Objective To explore the optimal usage protocol of a modified superficial venous reflux occlusion device in thrombolytic therapy for lower extremity deep venous thrombosis(DVT),so as to specify its compression site,inflation volume,and balloon pressure.Methods A total of 60 patients undergoing lower extremity DVT were randomly divided into control group and observation group,with 30 cases in each group.Control group:the compression point of great saphenous vein was 4-5 cm above the ankle joint,and small saphenous vein was 8-10 cm above the ankle joint,with an inflation volume of 12-15 mL and a balloon pressure of 110-120 cmH2O.Observation group:the compression point of the great saphenous vein was 6-8 cm below the knee joint,and the small saphenous vein was the same as the control group,with an inflation volume of 8-10 mL.The degree of deep venous perfusion in the lower limbs(Thrombolysis in Myocardial Infarc-tion[TIMI]grade),superficial venous occlusion efficacy,and patient comfort between the two groups were compared.Results The observation group showed significantly higher rates of deep venous perfusion grade Ⅲ(93.33％),superficial venous occlusion grade 0(80.00％),and the proportion of moderate and high comfort levels(96.67％)were significantly higher than those in the control group(46.67％,26.67％,70.00％),and differences were statistically significant(P<0.001).The balloon pressure in the observation group was significantly lower than that in the control group([70-100 vs.110-120]cmH2O)(P<0.001).Conclusion The optimized protocol for the modified occlusion device is as follows:great saphenous vein compression at 6-8 cm below the knee joint,small saphenous vein compression at 8-10 cm above the ankle,with an inflation volume of 8-10 mL and a balloon pressure of 70-100 cmH2O.This protocol can effectively enhance deep venous perfusion,improve superficial venous occlusion,and increase patient comfort.关键词
