Revascularização fêmoro-poplítea com stent de nitinol autoexpansível supera: análise de patência, desfechos clínicos e características e epidemiológicas

Abstract

Describe the clinical-epidemiological profile, health outcomes and primary patency on patients who were underwent to percutaneous transluminal angioplasty (ATP) procedure with Supera® stent implants on the femoro-popliteal segment in an hemodynamic service in southern Brazil. Materials and Methods:Retrospective cohort study, performed from march to december from 2021 by consulting the medical records from a tertiary hospital located in Passo Fundo, Rio Grande do Sul, Brazil, with the variables age, gender, skin color, risk factor, comorbidities, classification of the clinical picture, classification of the lesion, artery treated, limb, number of stentd and follow-up with health outcomes in 6 and 12 months. The analysis included descriptive statistics and the Kaplan Meier estimator for primary patency evaluation. Results: Sample of 93 patients, predominantly male 67,7%, average age of 70,2 years (±9,32). In relation to behavioral characteristics and health, were observed that ½ were current or previous smokers, 67,7% hypertensive and 41,9% diabetic, moreover, 21,5% of the patients were diagnosed with small trophic lesion, and 30,1% with TASC D lesions. The highest prevalence of procedures were on the superficial femoral artery 47,5%, left limb 51,5%, 24,7% of the patients had reintervention in the analyzed time, of these 17,2% were in others segments of the vessel due to evolution of the atherosclerotic process, and 7,4% on the stent Supera®, 24,7% of the patients had amputations. In addition, a primary patency of 84,5% in 12 months was estimated. Conclusion: The clinical epidemiological profile of the patients that underwent to ATP with stent Supera® was composed mostly of men, elderly, with white skin color, hypertensive, with a historical of cardiovascular comorbidities and clinical presentation of critical limb ischemia. The most prevalent clinical outcome were the full recovery and the less prevalent were stent reintervention. Besides that, the primary patency in the medium term analyzed by the outcome of stent reintervention by the Kaplan Meier estimator was considered satisfactory considering the severity of the clinical presentation and complex arterial lesion of the patients in the sample.
