Summary
Obstructive sleep apnea syndrome (OSAS) significantly increases the risk of intracranial aneurysms. Patients with OSAS had larger aneurysms, suggesting OSAS is a key risk factor for aneurysm development.
Area of Science:
- Neurology
- Sleep Medicine
- Vascular Medicine
Background:
- Obstructive sleep apnea syndrome (OSAS) is linked to cerebrovascular disease.
- Intracranial aneurysms pose life-threatening risks.
Purpose of the Study:
- To investigate the association between OSAS and intracranial aneurysms.
- To determine if OSAS is an independent risk factor for intracranial aneurysms.
Main Methods:
- Retrospective review of 564 patients undergoing polysomnography and brain MRA.
- Calculation of prevalence and measurement of intracranial aneurysm size.
- Statistical analysis adjusting for confounding factors (age, sex, BMI, smoking, alcohol).
Main Results:
- Prevalence of intracranial aneurysms was 12.1% in OSAS patients versus 5.9% in non-OSAS patients (p=0.031).
- OSAS remained a significant independent risk factor (OR: 2.32; 95% CI: 1.07-5.04).
- Aneurysms were larger in the OSAS group (3.2 ± 2.0 mm vs. 2.0 ± 0.4 mm, p=0.013).
Conclusions:
- A significant association exists between OSAS and intracranial aneurysms.
- OSAS may be an independent risk factor for intracranial aneurysm development and growth.

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
