Summary
Carotid webs, rare causes of stroke, can be difficult to diagnose. Prompt identification is crucial, especially in younger populations, to prevent recurrent strokes.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- A young male presented with stroke symptoms after neck manipulation.
- Initial CT was unremarkable, but subsequent MRI revealed an embolic infarct.
Purpose of the Study:
- To report a case of stroke secondary to a carotid web.
- To highlight diagnostic challenges and the importance of considering carotid webs in stroke etiology.
Main Methods:
- Utilized MRI, ultrasound, and intraoperative findings.
- Histopathology confirmed the presence of a carotid web with thrombus.
Main Results:
- Identified a mobile thrombus at the origin of the internal carotid artery (ICA).
- Confirmed a carotid web associated with thrombus formation via histopathology.
Conclusions:
- Carotid webs are a rare but significant cause of stroke, particularly in young adults.
- Accurate diagnosis of carotid webs is essential due to high stroke recurrence rates.
- Increased awareness and specialized sonographer training are needed for early detection.

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 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.
