Abstract:
Objective:To evaluate the safety and efficacy of a combination of percutaneous mechanical thrombectomy (PMT) and drug coated balloon(DCB)for the treatment of in-stent restenosis(ISR) and arterial thrombosis of the lower extremity.Methods:The clinical data of 53 patients treated with PMT + DCB were analyzed retrospectively, including 38 cases of ISR and 15 cases of arterial thrombosis. 33 patients were males and the others were females , the mean age was (68.6±9.4) years . Patients were followed at 30 days, 6 months, and 12 months concerning clinical symptoms, calculation of ABIs and duplex ultrasonography.Results:Procedural success was achieved in all 53 patients. One patient died of cardiovascular event perioperatively. 6 operation-related complications occurred including 5 cases of distal embolism during the PMT managed by using 5 F angiography catheter suction and one case of artery perforation during PMT procedure, a balloon was used to cover it. 47 (88.6%) patients completed 12-month follow-up, the TLR was 10.6% (5/47). One patient had the amputation 4 months later; There were 7 cases with arterial restenosis.PMT+ DCB were performed again in 4 cases, 1 case received stent implantation and 2 cases treated by medication.Conclusion:The use of combination of PMT and DCB is a safe and effective method to treat ISR and arterial thrombosis of the lower extremity.
