Objective Toinvestigatethethrombusclinicalcurativeeffectandpracticalvalueintreatmentofdeepveinthrombosis (DVT)byusingmodifiedaspirationcatheter.Methods Atotalof35patientswhometthediagnosticcriteriaofDVTwererandomly assignedintoexperimentalandcontrolgroups.Afterasufficientpreoperativepreparation,thepatientsweredividedintotheexperimentalgroup (n=18,usingmodifiedaspirationcatheterwithsubsequenturokinasethrombolysisandconventionalanticoagulationtherapy)andthe controlgroup [n=17,usingthe8Fvascularsheaths (COOK,USA)duringtheprocedure,subsequenturokinasethrombolysisand conventionalanticoagulationtherapy].Thepatencyofvessels,theperimeterdifferenceandthecomplicationweredocumented.Theresultswere comparedbetweenthetwogroups.Results Inexperimentalgroup,thrombusremovalofgradeⅣ (removalratelessthan0%)was 0%in0case,gradeⅢ (removalratelessthan50%)was5.56%in1case,gradeⅡ (removalrategreaterthan50%)was94.44%in ncontrolgroup,thrombusremovalofgradeⅣwas23.53%in4cases,gradeⅢwas52.94%in9cases,gradeⅡwas23.53%in4cases.
