Predictors of success of retrograde angioplasty of superficial femoral artery occlusive diseases.

Background: Endovascular procedures are considered effective and safe as management options in cases of superficialfemoral artery (SFA) atherosclerotic occlusive diseases especially retrograde access procedure which gives a hightechnical success rate and a high percentage of lower limb salvage with a low risk of complications and morbidity.Patients and Methods: This is a prospective study clinical trial one arm conducted on 50 patients suffering from criticallower limb ischemia with SFA occlusive diseases (Rutherford classification category 2–6) presented from May 2020 toJune 2022 to the Vascular Department, Beni-Suef University Hospital, and Vascular Departments, Military Hospitals.Results: The patency was kept in technical successful cases at 1, 3, 6, and 12 months in 100, 96, 92, and 80% of cases,respectively.Conclusion: There are many factors that predict the success of retrograde angioplasty in management of SFA occlusivediseases, maximize the likelihood of successful CTO crossing and pose the patency and amputation rates.
