This article discusses the use of occipital artery-vertebral artery (OA-VA) bypass as a treatment option for patients with cerebral hemodynamic compromise. The study reviews the techniques and outcomes of OA-VA bypasses and includes data from four institutional cases and 27 cases from the literature. The majority of patients were male with a median age of 62 years. The most common diagnosis was intracranial atherosclerosis, and surgical indications included flow augmentation in vertebrobasilar insufficiency and cerebrovascular reconstruction. The study found that OA-VA bypass was effective in improving symptoms in the majority of cases. However, the complex anatomy and uncommon indications make the technique challenging to adopt worldwide. The authors suggest that surgical education should focus on expanding knowledge of OA-VA bypass. [Extracted from the article]
