Factores de risgo asociados a EVC en joven con foramen oval permeable

Entre los factores de riesgo en personas jóvenes de sufrir un accidente cerebral ( EVC) vascular se encuentra la persistencia del agujero oval. En el Instituto Nacional de Neurología y Neurocirugía se han atendido a 2,870 pacientes con (EVC). La prevalencía del foramen oval es una causa de los EVC en jóvenes y puede ser detectado en un 30 a un 50% y puede variar con la edad de 3 a 5 mm y esta presente en un 10% de la población pero no siempre es sintomático o es detectado. En varios casos de existir con una trombosis venosa periférica en otros la explicación es difícil. Se analizan otros factores en el artículo. El tratamiento es aún no uniformemente aceptado

Clinical Presentation and Magnetic Resonance Findings in Sellar Tuberculomas

Background and Importance. Sellar tuberculomas are extremely rare lesions with nonspecific clinical manifestations. The tuberculous infection of the pituitary gland and sellar region is characterized by the presence of an acute or chronic inflammatory reaction and may occur in the absence of systemic tuberculosis. The diagnosis is difficult prior to the surgery. An adequate diagnostic and antituberculous drugs usually result in a good outcome. Clinical Presentation. We report four cases of sellar tuberculoma, 3/1 female/male, age range: 50–57 years. All patients had visual disturbances and low levels of cortisol. Conclusion. The clinical diagnosis of sellar tuberculoma is a challenge and should be suspected when a sellar lesion shows abnormal enhancement pattern and stalk involvement, and absence of signal suppression in FLAIR

Abstract 171: Embolization of non‐ruptured intracranial aneurysms with flow diverter devices in Mexico: Quick responses

Introduction Flow diverters (FD) are stent‐type devices that enable the exclusion of intracranial aneurysms in clinical scenarios where coil‐type devices exhibit high failure rates. However, its effectiveness hasn't been examined in countries with low and middle incomes, like Mexico. Methods Longitudinal, retrospective study of the patients who received care at a tertiary center between November 2020 and April 2022. Adults older than 18 with non‐ruptured intracranial aneurysms were included. After treatment with FD, post‐procedure control angiograms were performed between three and six months later. The occlusion rate was evaluated using the O'Kelly‐Marotta scale. Results There were 23 patients —2 of whom had double aneurisms—, 20 women, with an average age of 51.4 years (±13.3). 19 saccular aneurysms, 4 fusiform aneurysms, and 2 dissecting aneurysms were treated. Neck measurements were in the range of 1.9 to 19 mm. Angioplasties were performed as part of the procedure on four patients, and successful liberation was achieved in all procedures. Between three and six months of follow up, total occlusion was observed in 14 aneurisms, and three had less than 5% residuals. Only three late procedural related complications were found. Conclusion The patients treated with FD at our reference center had complex aneurysms. Complete occlusion was achieved in 56% of the treated aneurysms during follow up. The use of the FD appears to be safe and to have a high level of effectiveness, similar to what has been described in international reports
