Estudo prospectivo comparativo entre a endarterectomia e a angioplastia com stent e proteção cerebral no tratamento das lesões ateroscleróticas carotídeas: resultados em 30 dias Prospective and comparative study between endarterectomy and stent angioplasty with cerebral protection in carotid atherosclerotic lesions: 30-day results

Objective: To comparatively analyze the 30-day results between endarterectomy and angioplasty using self-expandable stent and filter protection in the treatment of carotid bifurcation atherosclerotic lesions. The primary endpoint was to analyze stroke and death rate, as well hospitalization time. Methods: Comparative and prospective study in 80 symptomatic and asymptomatic patients, with carotid bifurcation stenotic lesions greater than 60 and 70%, respectively. The patients were divided into two groups of 40 and assessed according to gender, age, associated comorbid conditions and smoking. Results: The stroke and death rate was 5.0% for both techniques. There was only one case of transient ischemic attack (2.5%) in the endovascular group. Regarding hospitalization time, it was significantly lower in favor of the endovascular technique, with statistical significance (P < 0.002). Conclusions: This study demonstrated a 5.0% incidence of stroke and death in 30 days considering both techniques. However, the endovascular group presented a statistically significant shorter hospitalization time than the endarterectomy group (P < 0.002).
