Endovascular Therapy Of TASC Ⅱ C And D Femoral Popliteal Arteriosclerosis Obliterans In The Short And Medium Term

objective: to evaluate the feasibility,safety and short term patency rate of intracavitary interventional therapy for TASC Ⅱ C and D lesions of lower extremity arteriosclerosis oblocclusion.Methods: retrospective analysis was performed on 63 cases of TASC Ⅱ C and D grade lower extremity arteriosclerosis occlusions treated with intracavity interventional therapy in this center.Results: A total of 61 patients received intracavitary interventional therapy,among which 61 were successful and 3failed to receive interventional therapy after repeated attempts,so conservative treatment was given.The technical success rate was 95.38%(62/65),the incidence of perioperative complications was 14.75%,,and the mortality rate was 0%.ABI0.83±0.14 of dorsal foot artery after surgery was significantly increased compared with 0.36±0.14 before surgery(P<0.05).After 1,3,6,12,18 and 24 months of follow-up,the first-phase patency rate was 98.38%、90.32%、85.24%、77.19%、60.38%and 47.91%,respectively.The patency rate of the second phase in 12 months and 24 months was 78.94% and 71.11%.Conclusion: Endovascular therapy is an effective and safe method for the treatment of arterial occlusion of lower limbs,even for long and serious lesions.However,the selection of intracavitary Endovascular therapy still needs larger sample data and longer statistical observation to determine.
