Occipital dural arteriovenous fistulas
Diagnostic Imaging in Clinical Medicine
|January 1, 1985
Summary
Occipital dural arteriovenous fistulas can cause pulsatile tinnitus or intracerebral hemorrhage. Angiography is crucial for diagnosis, with embolization being the preferred treatment, sometimes supplemented by surgery.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Occipital dural arteriovenous fistulas are rare vascular malformations.
- These fistulas involve abnormal connections between dural arteries and veins in the occipital region.
Observation:
- Three cases of occipital dural arteriovenous fistulas are presented.
- Clinical presentations included pulsatile tinnitus and occipital intracerebral hematoma.
Findings:
- Thorough bilateral angiography, including arterial and venous phases with subtraction, is essential for accurate diagnosis.
- Embolization of the external carotid artery territory is the primary treatment modality.
- Surgical intervention may be necessary as an adjunct to embolization.
Implications:
- Early and accurate diagnosis through comprehensive angiography is key to successful management.
- Endovascular embolization offers a primary treatment option with potentially better outcomes than surgery alone.
- A multidisciplinary approach combining endovascular and surgical techniques may be required for complex cases.
