【Abstract】ObjectiveTo explore the optimal usage protocol of a modified superficial venous reflux oclusion device in thrombolytictherapyforlowerextremitydeepvenous thrombosis（DVT），soas tospecifyitscompressionsite，inflation volume，andbaloon pressure.MethodsAtotal of 6Opatients undergoinglower extremityDVTwererandomlydivided into control groupandobservation group，with 3O cases ineach group.Control group：thecompression point of great saphenous vein was 4- 5 cm above the ankle joint，and small saphenous vein was 8--10 cm above theankle joint，withaninflation volume of 12 -15mL and a ballon pressure of 110-120cmH2O . Observation group：the compression point of the great saphenous vein was6-8cm below the knee joint，andthe smallsaphenous vein was the same as thecontrol group，with an inflationvolumeof8-1OmL.Thedegreeofdeepvenousperfusioninthelower limbs（Thrombolysis inMyocardial Infarction[TIMI] grade），superficial venousocclusion eficacy，andpatientcomfort between thetwo groups were compared. ResultsThe observation group showed significantly higher rates of deep venous perfusion grade Il （ 93.33% ），superficial venous occlusion grade 0（ 80.00% ），and the proportion of moderate and high comfortlevels （ 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）．Theballonpressure intheobservation group wassignificantlylower thanthatinthecontrol group（[7o－100 vs. 110 -120] cmH20 ） P<0. 001 ）.ConclusionThe optimized protocol for the modified occlusion device is as follows ：

great saphenous vein compresson at 6 -8 cm below the knee joint，smallsaphenous vein compression at cm above the ankle，with an inflation volume of8-1O mL and a ballon pressure of 70-100cmH2O .This protocol can effectively enhance deep venous perfusion，improve superficial venous occlusion，and increase patient comfort.

深静脉血栓形成（deepvenousthrombosis，DVT）是指血液在深静脉腔内不正常凝块而造成阻塞，引起静脉回流受阻和障碍的一系列并发症[1]，是仅次于心肌梗死和脑卒中的第三大最常见的心血管疾病[2]。（剩余5536字）
