Abstract：ObjectiveTo explore the application effect of Straub thrombus rotary cutter in lower extremity deep venous thrombosis.Methods88 patients with lower extremity deep venous thrombosis treated in our hospital from October 2009 to August 2013 were randomly selected.Patients were divided into observation group and control group according to the simple randomization principle,and each group had 44 cases.The control group was given drug thrombolysis treatment,while the observation group was given the plan of Straub thrombus rotary cutter interventional therapy.The change of the diameter of the lower extremity,cure rate,the incidence of complications and venous valve function of patients between the two groups were compared.ResultsThe mean follow-up was(27.2±10.9)months.The decrease of diameter of the lower extremity in observation group and control group was(4.0±1.2)cm and(1.3±0.5)cm respectively,and the cure rate in observation group and control group was 90.8%and 34.2%respectively,and the difference between two groups was significant(P<0.05).Incidence of incidence of complications in observation group was obviously lower than that in control group(P<0.05).The venous valve function in observation group was obviously better than that in control group(P<0.05).ConclusionThe application effect of Straub in lower limbs deep venous thrombosis is more effective than that of the single drug thrombolytic therapy,and it has the advantages of safety,quickly clearing thrombus and resuming normal blood flow,reducing complications due to venous reflux disorder.It is worthy of clinical promotion and application.
