Abstract:
Objective To explore the necessity of placing an inferior vena cava filter(IVCF)during interventional therapy for acute lower extremity deep venous thrombosis(DVT)complicated with severe May-Thurner syndrome(MTS).Methods Patients with acute left lower extremity DVT complicated with severe MTS were retrospectively selected and divided into observation group(n=36)and control group(n=36)according to whether IVCF was implanted or not.Pulmonary embolism(PE)was evaluated using compu-ted tomography pulmonary angiography(CTPA).The improvement of the affected limb signs and the occurrence of PE symptoms during treatment were observed.The presence of trapped thrombus was checked during filter removal.The PE incidence,hospitaliza-tion costs,operation time,and hospital stay were compared between the two groups.Results Both groups had a higher thrombus clearance rate after interventional surgery,and the proportion of new small branch PE was lower without significant differences between the two groups(8.3%vs 5.6%,P=1.000).The signs of the affected limbs improved significantly,and no PE-related symptoms occurred during treatment.No obvious trapped thrombus was found when the filter was removed in the control group.Compared with the control group,the observation group had significantly reduced hospitalization costs and operation time(P<0.05).Conclusion For patients with acute lower extremity DVT complicated with severe MTS,omitting IVCF placement during interventional surgery does not increase the risk of PE and can reduce operation time and hospitalization costs.
