[en] ABSTRACT 1. Introduction The benefit of carotid revascularization (CR) is limited by the length of the technique used (endarterectomy, angioplasty with stent). The occurrence of restenosis after surgery, although usually asymptomatic, may increase the risk of stroke or be a subsidiary of a new treatment. In the literature there is great ignorance about the factors associated with restenosis in the short and long term after RC procedures. 2. Objective The main aim of our study is to collect the morbidity and mortality of our series and determine the prognostic factors associated with restenosis. 3. Method Retrospective analysis of a sample of 231 patients who received revascularization treatment with ACS in Interventional Neuroradiology section of our center between 2005 and 2011. The incidence of major perioperative complications (myocardial infarction, stroke, death) and long-term stroke was recorded, and one year follow-up was performed using ultrasound. The restenosis rate was determined and possible clinical, demographic and therapeutic factors involved were analyzed. 4. Results The overall morbidity and mortality in our series was 6.9%. Analyzing the incidence of major complications and intraoperative hemodynamic effects, despite the high surgical risk of the sample, no deviations were detected with respect to the published series. The restenosis rate at one year was 3.8%, half of them in the first month. In the statistical analysis of all study variables relationship between the female and early restenosis (p = 0.04) it was found. 5. Discussion The number of perioperative major complications in our center is maintained within the required minimum. In our study, women appear to be at greater risk of restenosis 30 days after ACS. No influence of gender or other factors found in the long-term restenosis.6. Conclusions Contrary to the findings of other work, female gender behaves as an independent predictor regarding the development of restenosis in carotid angioplasty procedures. The identification of risk factors can help develop therapeutic and monitoring strategies.

[gl] 1. Introdución O beneficio da revascularización carotídea (RC) está limitado pola duración da técnica empregada (endarterectomía, anxioplastia con stent). A aparición de reestenosis tras a cirurxia, aunque xeneralmente é asintomática, pode incrementar o risco de ictus ou ser subsidiaria dun novo tratamento. Existe na literatura un gran descoñecemento sobre os factores relacionados coas reestenosis a curto e longo prazo tras os procedementos de RC. 2. Obxectivo O obxectivo principal do noso estudo é recoller a morbimortalidade da nosa serie e determinar os factores prognósticos relacionados coa reestenose. 3. Método Análise retrospectivo dunha mostra de 231 doentes que recibieron tratamento revascularizador con ACS na sección de Neurorradioloxía Intervencionista do noso Centro entre 2005 e 2011. Rexistrouse a incidencia de complicacións maiores perioperatorias (infarto de miocardio, ictus, morte) e ictus a longo prazo, e realizouse un seguimento ao ano mediante ecografía. Determinouse a tasa de reestenose e se analizaron os posibles factores clínicos, demográficos e terapéuticos implicados. 4. Resultados A morbimortalidade total da nosa serie foi do 6,9%. Analizando a incidencia de complicacións maiores e os efectos hemodinámicos intraoperatorios, a pesar do elevado risco cirúrxico da mostra, non se detectaron desviacións respecto ás principais series publicadas. A tasa de reestenose a un ano foi do 3,8%, a metade delas durante o primeiro mes. Na análise estatística de todas as variables de estudo, encontrouse unha relación entre o género feminino e a reestenose precoz (p=0,04). 5. Discusión O número de complicacións maiores perioperatorias no noso Centro se mantén dentro do mínimo exigido. No noso estudo, as mulleres parecen ter maior risco de restenose a 30 días despois de ACS. Non se encontrou influencia do xénero nin de outros factores nas reestenosis a longo prazo. 6. Conclusións Contrariamente ao descrito por oturos traballos, o xénero feminino se comporta como un predictor independente respecto ao desenvolvemento de reestenose nos procedementos de anxioplastia carotídea. A identificación de elementos de risco pode axudar a elaborar estratexias terapéuticas e de seguimento.
