Growth on an arteriovenous malformation: a case report
The Yale Journal of Biology and Medicine
|November 1, 1977
Summary
This case study presents an intracerebral arteriovenous malformation (AVM) that grew over eight years. Headaches associated with the AVM were relieved by antihypertensive medications, suggesting distension as the cause.
Area of Science:
- Neurology
- Vascular Neurology
- Neuroimaging
Background:
- Intracerebral arteriovenous malformations (AVMs) are complex vascular lesions.
- The natural history and growth patterns of AVMs require further investigation.
- Understanding AVM-associated symptoms is crucial for patient management.
Observation:
- A single early filling vein was noted on initial arteriogram in the region of a future large AVM.
- The AVM significantly enlarged over an eight-year period.
- The patient experienced headaches attributed to the AVM.
Findings:
- The intracerebral arteriovenous malformation demonstrated growth over eight years.
- Antihypertensive medications effectively relieved the patient's headaches.
- The size increase of the AVM is speculated to be the cause of headaches.
Implications:
- This case highlights the potential for intracerebral AVM growth.
- The findings suggest a link between AVM distension and headache development.
- Further research into AVM pathophysiology and symptom correlation is warranted.
