What Are the Risks of Having Narrow Blood Vessels in the Brain?

The hazards of narrow cerebrovascular lumen include inadequate activity tolerance, increased intracranial pressure, and cerebrovascular spasm, details are as follows:

1. Inadequate Activity Tolerance

Narrow cerebrovascular lumen can reduce blood supply to local brain tissue. During daily activities, accelerated blood circulation can lead to inadequate blood perfusion in brain tissue, resulting in headaches, dizziness, and other discomforts, accompanied by inadequate activity tolerance.

2. Increased Intracranial Pressure

Narrow cerebrovascular lumen easily causes acute ischemia and hypoxia in local brain tissue, which subsequently leads to interstitial fluid leakage, forming cytotoxic cerebral edema, resulting in increased intracranial pressure, headaches, vomiting, and other symptoms.

3. Cerebrovascular Spasm

Patients with narrow cerebrovascular lumen experience relatively high pressure on the vessel wall during blood circulation. If not promptly addressed, it can cause cerebrovascular spasm, hemiplegia, aphasia, and other phenomena.

In addition to the above common hazards, the hazards of narrow cerebrovascular lumen also include epilepsy, cerebral infarction, cerebral hemorrhage, and more. Patients should seek medical attention promptly to improve blood and oxygen supply to brain tissue and prevent severe complications.
