The basilar artery is a critical component of the cerebral circulation, supplying a significant portion of the blood flow to the brain (Wojak et al., 1991). The anatomy of the basilar artery, including its bifurcation angle, has been linked to the formation of intracranial aneurysms (Stapleton et al., 2016; Tütüncü et al., 2014; Can et al., 2015). Studies have shown that wider basilar artery bifurcation angles are associated with the presence of basilar artery apex aneurysms (Stapleton et al., 2016; Tütüncü et al., 2014). Additionally, the formation of basilar tip aneurysms has been correlated with specific vascular anatomy, such as a larger P1-P1 angle, which represents a greater divergence of flow from the originating basilar artery into both of the daughter posterior cerebral artery vessels (Can et al., 2015). Furthermore, the basilar artery has been implicated in various pathological conditions, such as basilar artery occlusion, which can lead to devastating consequences (Chu et al., 2015). The occlusion of the basilar artery has been identified as an easily missed emergency, emphasizing the importance of prompt recognition and intervention (Chu et al., 2015). Additionally, dolichoectatic basilar artery has been associated with vertebrobasilar infarcts and hydrocephalus (Besson et al., 1995). The clinical significance of the basilar artery is further underscored by its involvement in surgical procedures, such as arterial and vein grafts to the basilar artery (Whang et al., 1975). These procedures have been investigated to compare blood flow and patency rates, providing valuable insights into potential treatment options for conditions affecting the basilar artery (Whang et al., 1975). Moreover, the basilar artery has been the subject of anatomical studies, aiming to elucidate its microscopical anatomy and variations in location on the ventral surface of the pons (Sultana et al., 2014; Tulleken & Luiten, 1987). These studies contribute to a comprehensive understanding of the basilar artery’s structure and its potential implications in clinical practice. In conclusion, the basilar artery plays a crucial role in cerebral circulation and is implicated in various pathological conditions and surgical interventions. Understanding its anatomical features, variations, and associations with specific pathologies is essential for the diagnosis, management, and treatment of conditions affecting this vital arterial structure.
Basilar artery stroke, often referred to as a brainstem stroke, is a serious medical condition that occurs when the basilar artery, a critical blood vessel in the brain, becomes blocked or damaged. This type of stroke can have severe consequences, affecting various bodily functions controlled by the brainstem. In this article, we’ll provide clear and simple explanations for basilar artery stroke, including its types, causes, symptoms, diagnostic tests, treatment options, medications, and surgical procedures.
A basilar artery stroke occurs when there is a problem with the basilar artery, which supplies blood to the brainstem and other important brain structures. This interruption in blood flow can lead to various neurological symptoms and complications.
Types of Basilar Artery Strokes:
There are two main types of basilar artery strokes:
a. Ischemic Basilar Artery Stroke: – This type occurs when a blood clot or plaque buildup blocks the blood flow in the basilar artery.
b. Hemorrhagic Basilar Artery Stroke: – This type results from a rupture in a blood vessel within or around the basilar artery, causing bleeding in the brain.
Common Causes of Basilar Artery Stroke (Top 20):
Basilar artery strokes can happen due to various factors, including:
- High blood pressure
- Smoking
- Diabetes
- Atherosclerosis (narrowing of arteries)
- Heart diseases
- Blood clot formation
- Brain aneurysms
- Blood vessel abnormalities
- Trauma or injury to the head
- Certain medications
- Alcohol abuse

Diagnostic Tests for Basilar Artery Stroke
Diagnosing a basilar artery stroke typically involves a series of medical tests. Some of the most common ones include:
- CT Scan (Computed Tomography): This imaging test can reveal bleeding or blockages in the brain.
