Anatomical variations of the intracranial arteries and their association with intracranial aneurysms: Insights from digital subtraction angiographies.

The purpose of this study was to identify the anatomical variants (AVs) in the intracranial arterial circulation of patients who underwent neuro-interventional procedures (NIPs) and to describe their relationship with intracranial aneurysms (IA). We performed a cross-sectional analysis of angiographic images from patients who underwent NIP at the Interventional Neuroradiology Department of the National Institute of Neurology and Neurosurgery in México between July 1, 2020, and January 1, 2022. After reviewing images from 150 NIPs, we found 144 AVs.

Successful treatment of rapid onset Foix-Alajouanine syndrome following hyperselective endovascular embolization of thoracic dural arteriovenous fistula: Case report, technical note and literature review.

Foix-Alajouanine syndrome is an extremely rare yet important differential diagnosis for subacute lower limb weakness in middle-aged to elderly adults. Current understanding of the pathophysiology of this disease, along with recent publications on successful endovascular interventions, has shifted the perspective and clinical approach for its management. Nonetheless, neurosurgical pathways for clinical treatment are still preferred over endovascular embolization.

Clinical and anatomic description of patients with arteriovenous malformation treated with endovascular therapy in a Mexican population.

Objective: Arteriovenous malformations (AVMs) are benign congenital lesions. The estimated prevalence is 10-18 per 100,000 individuals, with an incidence rate of 1.1-1.

Persistent trigeminal artery associated with an occipital arteriovenous malformation: a case report and literature review.

Background: Persistent trigeminal artery or persistent primitive trigeminal artery (PTA) is the most common carotid-basilar anastomosis in both cadaveric and live patient studies, followed by persistent hypoglossal and persistent otic arteries. Approximately 0.2% of all angiographies reported this finding.
