Abstract:
Objective To discuss the application of bidirectional dual loop technique in retrieving Aegisy inferior vena cava filters.Methods The clinical data of 12 patients with deep vein thrombosis in the lower limbs complicated by pulmonary embolism,who received mechanical thrombectomy and Aegisy inferior vena cava(IVC)filter implantation at the Zhoukou Municipal Central Hospital of China from January 2016 to November 2023,were retrospectively analyzed.The retrieval of Aegisy IVC filters beyond the time window was tried by standard methods,guide wire stripping,balloon dilatation,unidirectional single loop technique,unidirectional dual loop technique,etc.However,because of the difficulty in retrieval of filter,bidirectional dual loop technique had to be used.The indwelling time of the IVC filters was 30-365 days,with an average time of 105 days.Results The IVC filter was completely removed in 11 patients.Angiography showed that IVC was unobstructed,no contrast extravasation was observed,and the average operation time was 126 minutes.The retrieval of filter failed in one patient,and the patient had to receive anticoagulation therapy lifelong.No surgery-related complications occurred.Conclusion For retrieving Aegisy IVC filters beyond the time window,bidirectional dual loop technique is clinically safe and effective,and this technology is worthy of clinical promotion and application.
