radio frequency denervation, tibial arteries, atherosclerosis of the peripheral arteries
Brief summary
Angioplasty augmented radiofrequency denervation popliteal artery, in our opinion, will remove the spasm with macro and microcirculatory blood flow, which increases revascularization patency of tibial arteries.
Interventions
Under local anesthesia using the standard endovascular access and renders the affected arterial segment. Are stenosis or occlusion of the artery, the hydrophilic guide. Occlusion or subintimal perform transluminal recanalization of the artery. Then do balloon angioplastic stenosis or occlusion. Drug therapy includes the administration of aspirin before the procedure (160-300 mg/day) starting at least one day, and heparin during the procedure (5000 IU intravenously). After the procedure, all patients are administered aspirin (100 mg daily) for a long time.

Occlusion or subintimal perform transluminal recanalization of the artery. Then do balloon angioplastic stenosis or occlusion. Then in 3 portion of the popliteal artery starts ablation by the use Vessix Renal Denervation System Balloon performed radiofrequency denervation. After removal of the balloon, control angiography is performed. Drug therapy includes the administration of aspirin before the procedure (160-300 mg/day) starting at least one day, and heparin during the procedure (5000 IU intravenously). After the procedure, all patients are administered aspirin (100 mg daily) for a long time.
