Abstract:
Objective To evaluate the feasibility and safety of endovascular intervention for the treatment of filter-related long segment obstruction of IVC and iliac vein.Methods From January 2014 to October 2016,a total of 8 patients with filter-related chronic long segment obstruction of IVC and iliac vein were treated with percutaneous transcatheter angioplasty (PTA) and stent implantation.The clinical data and imaging materials were collected.The endovascular interventional treatment methods were discussed,and the technical success rate,procedure-related complications and follow-up results were analyzed.Results Successful recanalization of the obstructed IVC-iliac vein segment was achieved in all 8 patients.In 7 patients,angiography performed immediately after PTA and stent implantation showed that the blood flow in the stent was smooth and the collateral vessels were decreased.In one patient,acute in-stent thrombosis occurred after PTA and stent implantation,then catheter-directed thrombolysis had to be adopted,and angiography performed 2 days later indicated that in-stent thrombosis was completely dissolved and the blood flow resumed smoothly.The patients were followed up for 2-13 months,with a mean of (4.7±3.9) months.Reexamination with both CT and venography of lower limb showed that the stent was kept in good position to the last visit in all 8 patients.Slight intimal hyperplasia was observed in 3 patients,but the blood flow was unobstructed.Conclusion Long term implantation of filter may cause filter-related chronic long segment obstruction of IVC and iliac vein.PTA with stent implantation is a safe and feasible method to effectively open the occluded vessels.
