Anterior communicating artery aneurisms (ACAA) are complex and require endovascular or microsurgery approaches. The use of minimally invasive microsurgery techniques is evolving. We present the case of a 34-year- old patient with a broad neck, non-broken, ACAA with a Glasgow coma scale of 15 points. A lateral supra-orbitary approach with total clipping of the ACAA using intra-operatory fluorescein angiography was performed. The objective was accomplished successfully and safe, optimizing both intra-operative and hospitalization times, thus, maximizing patient comfort, esthetic and prompt return to normal duties.

Introducción: Los gliomas conforman la mayoría de los tumores primarios que surgen del parénquima cerebral. Reporte de caso: varón de 39 años, con antecedente de hace 08 años de oligodendroglioma grado II sometido a cirugía para exéresis completa, más quimioterapia y radioterapia; que se presentó con 6 semanas de enfermedad caracterizada por crisis convulsivas tónico clónicas generalizadas, adormecimiento y disminución de fuerza de hemicuerpo derecho. El examen clínico revelo hemiparesia derecha a predominio braquial 2/5, Glasgow 15 puntos. En la resonancia cerebral se encontró extenso realce nodular de 4.8 cm localizado en región fronto-parietal izquierda, con abundante edema vasogénico ejerciendo efecto de masa. Se realiza segunda cirugía encontrando en anatomía patología un glioma de IV grado OMS. Conclusión: Los oligodendrogliomas son tumores de crecimiento lento...

Diffuse spinal cord injuries are rare and pose a diagnostic challenge. Low-grade gliomas are the most prevalent type, with primary astrocytomas being the most frequent subtype. We present the case of a 36-year-old man with a 13-year history of squeezing neck pain, which progressed with right hemiparesis and later with severe paraparesis and loss of sphincter control. A whole spine MRI scan showed diffuse neoproliferative lesions that spread throughout all the spinal cord segments. An open biopsy of the lesion in the T1-T2 segment was performed. The pathology report stated low-grade glioma. Treatment is controversial, so surgery was ruled out due to high morbidity. Radiotherapy and chemotherapy were chosen because they play an important role in controlling the disease.

Failed back surgery syndrome is a postsurgical phenomenon that involves persistent low back pain following one or more spinal surgeries. The multidisciplinary approach to its management includes both conservative and surgical treatments. Anterior lumbar interbody fusion (ALIF) has stood out as a surgical option for refractory pain. We present five cases of patients with failed back surgery syndrome treated with ALIF. These patients demonstrated reduced pain scale scores and significant improvement in functional capacity after the application of the abovementioned technique, suggesting its effectiveness in this group of patients who are refractory to conservative treatments. It should be noted that previous studies supporting the usefulness of ALIF mention the importance of careful patient screening, considering both preoperative factors (pain pathophysiology and accurate assessment of th...

Objetivo: La hidatidosis intracraneal es frecuente en la edad pediátrica. Los quistes grandes tienen indicación quirúrgica porque causan hipertensión endocraneana o déficit neurológico. El propósito de la cirugía es remover el quiste completo; sin ruptura y sin mayor daño del parénquima cerebral. Reporte de caso: presentamos tres casos, donde se describe le cuadro clínico e imágenes de la técnica quirúrgica realizada. Discusión: La extirpación total evita la siembra de protoescolices y de vesículas hijas, lo cual podría desencadenar meningitis, anafilaxia e hidatidosis cerebral secundaria o en caso más graves choque anafiláctico y muerte intraoperatoria del paciente. El éxito también dependerá de un tratamiento adecuado del quiste y de la adventicia de la cavidad quística.
