El abordaje transradial está ganando territorio en el campo neuroendovascular para procedimientos diagnósticos y terapéuticos. Menos complicaciones, menor tiempo hospitalario y mayor confort del paciente son características de este abordaje. Sin embargo, la transición del abordaje femoral clásico al abordaje radial es difícil de lograr en instituciones con protocolos establecidos. Presentamos nuestra experiencia inicial utilizando el abordaje transradial para angiografía cerebral diagnóstica realizados exitosamente logrando la cateterización de todos los vasos supra-aórticos.
Background: Basal ganglia and thalamic arteriovenous malformations (AVM) represent 10% of all AVM. They are associated with a high rate of morbidity and mortality due to their high hemorrhagic presentation and eloquence. Radiosurgery has been the first line treatment, whereas surgical removal and endovascular therapy are possible in selected cases. Deep AVM with small niduses and a single draining vein can achieve cure with embolization. Case Description: A 10-year-old boy with sudden headache and vomiting underwent a brain computed tomography scan that showed a right thalamic hematoma. Cerebral angiography revealed a small ruptured right anteromedial thalamic AVM with a single feeder arising from the tuberothalamic artery and a single drainage to the superior thalamic vein. Transvenous approach using precipitating hydrophobic injectable liquid 25%® achieved a complete obliteration of the lesion in a single-session. He was discharged home without neurological sequelae and maintained clinically intact at follow-up. Conclusion: Transvenous embolization of deep-located AVM as a primary treatment is curative in selected cases, with complication rates comparable to other therapeutic strategies.
Objectives: Endovascular treatment of intracranial aneurysms (IAs) has evolved in recent years and is currently the preferred treatment worldwide. We analyzed the trends in the number of patients, number of aneurysms, aneurysm characteristics, and techniques used in a pure endovascular cohort of patients treated in a reference center. Materials and Methods: Between 2010 and 2020, a retrospective data collection of patients who underwent endovascular intervention of IAs was performed. We used the Mann-Kendal test to evaluate the trends. In addition, the moving-average technique was used to assess smoother curves. Results: Eight hundred and forty-five aneurysms were treated in 765 patients, the mean age was 53.9 ± 14.6 years and 81% were women. The number of patients (P = 0.016) and aneurysms (P = 0.003) increased significantly. Unruptured (P = 0.029) and posterior communicating artery aneurysms increased their frequency of treatment (P = 0.042). Balloon remodeling (P = 0.01) and the use of flow diverters showed a positive trend (P = 0.016). Conclusion: There have been an increased number of patients and aneurysms treated endovascularly at our institution, including unruptured and posterior communicating aneurysms. Advanced endovascular techniques also increased. Comparative studies including surgical cases must be done in our region to determine the best approach.
Objetivo: proveer recomendaciones clínicas basadas en evidencia para el diagnóstico y tratamiento de la etapa aguda del ataque cerebrovascular isquémico en EsSalud. Materiales y métodos: se conformó un grupo elaborador de la guía (GEG) que incluyó médicos especialistas y metodólogos. El GEG formuló 8 preguntas clínicas a ser respondidas por la presente GPC. Se realizó búsquedas sistemáticas de revisiones sistemáticas y –cuando fue considerado pertinente– estudios primarios en Medline y Cochrane Controlled Register of Trials durante el 2018. Se seleccionó la evidencia para responder cada una de las preguntas clínicas planteadas. La certeza de la evidencia fue evaluada usando la metodología Grading of Recommendations Assessment, Development, and Evaluation (GRADE). En reuniones de trabajo periódicas, el GEG usó la metodología GRADE para revisar la evidencia y formular las recomendaciones, los puntos de buenas prácticas clínicas y el flujograma de diagnóstico y tratamiento. Finalmente, la GPC fue aprobada con Resolución N° 128-IETSI-ESSALUD-2019. Resultados: la presente GPC abordó 8 preguntas clínicas, divididas en cuatro temas: tamizaje, diagnóstico, tratamiento, soporte y rehabilitación. En base a estas preguntas se formularon 28 recomendaciones (8 fuertes y 20 condicionales), 38 puntos de buena práctica clínica, 1 nota de implementación y 2 flujogramas. Conclusión: el presente artículo resume la metodología y las conclusiones basadas en evidencias de la GPC para el diagnóstico y tratamiento de la etapa aguda del ataque cerebrovascular isquémico en EsSalud.
Introduction : Endovascular treatment of intracranial aneurysms has increased compared to microsurgery since the creation of the Guglielmi Detachable Coils (GDC), and is the treatment of choice in several centers worldwide. Our study aimed to analyze the trends over time of number of patients, number of aneurysms, rupture status, location, size and endovascular technique employed in a retrospective cohort of consecutive intracranial aneurysms treated during a 10‐year period. Methods : Data extracted from clinical records, surgical reports, angiographies and CT scans of 765 consecutive patients who underwent endovascular treatment of 845 intracranial aneurysms at our institution between January 2010 and December 2020 was carried out. The Mann‐Kendal test was used to assess time trends. The moving average technique was also employed, using one lagged observation, the current observation and one forward observation in order to create smoother curves. The statistical software Stata v14.0 (StataCorp, College Station, TX, USA) was used. Results : We evaluated 765 patients who underwent 845 endovascular treatments of intracranial aneurysms. Women represented 81% of the cohort. Mean age was 53.9 ± 14.6 years. We identified a significant increase in the number of patients (p = 0.016; p for moving average = 0.005) and in the number of aneurysms over time (p = 0.003; p for moving average = 0.003). For ruptured aneurysms, we did not find changes in the trends over time (p = 0.117; p for moving average = 0.1), whereas in the case of unruptured aneurysms, we identified a significant increase in their treatment (p = 0.029; p for moving average = 0.001). Posterior communicating (p = 0.042: p for moving average = 0.002), paraclinoid (p = 0.06; p for moving average = 0.019) and posterior fossa aneurysms (p = 0.813; p for moving average = 0.028) increased their frequency of treatment over time. Anterior communicating (p = 0.235; p for moving average = 0.21), middle cerebral artery (p = 0.431; p for moving average = 0.347) and internal carotid artery aneurysms (p = 1; p for moving average = 0.754) did not show differences over time. We did not identify changes over time in large (p = 0.31; p for moving average = 0.213), as well as width (p = 0.35; p for moving average = 0.876) and neck diameter (p = 1; p for moving average = 0.815). Balloon‐assisted coiling (p = 0.01; p for moving average = 0.003), flow diverters (p = 0.016; p for moving average < 0.001) and stent‐assisted coiling (p = 0.531; p for moving average = 0.014) showed a positive trend over time. Simple coiling (p = 0.75; p for moving average = 0.184) did not show significant variations over time. Conclusions : We identified a positive trend in the endovascular treatment of unruptured aneurysms, as well as posterior communicating artery, paraclinoid and posterior fossa aneurysms. Assisted‐coiling techniques and flow diverters also showed a positive trend over time. These results are in accordance with the increasing trends in endovascular treatment of intracranial aneurysms worldwide.
