Abstract

Objectives The aim of this study was to assess the durability of superficial femoral artery stents and factors that affect stent patency. Patients and methods This prospective study was carried out on 30 patients who were complaining of critical limb ischemia (CLI). CLI was recorded in 22 right lower limbs and in 11 left lower limbs. Results There was a significant correlation between the occurrenace of CLI and diabetes mellitus (P = 0.001), hypertension (P = 0.011), ischemic heart disease (P = 0.028), chronic renal failure (P = 0.001), and cerebrovascular disease (P = 0.001). In all, 59% of lesions treated were chronic total occlusions and the remaining 41% were for stenotic lesions. Trans-Atlantic Inter-Society Consensus (TASC) II A group lesions were found in 11 (33.3%) limbs; TASC II B group lesions were found in 13 (39.4%) limbs; TASC II C group lesions were found in five (15.2%) limbs; and TASC II C or D group lesions were found in four (12.1%) limbs. There was a significant (P = 0.001) decrease of primary and secondary patency in smokers and in diabetic patients. Conclusion Diabetes mellitus, hypertension, ischemic heart disease, chronic renal failure, and cerebrovascular diseases are risk factors for the occurrence of CLI.
