Summary
This case study presents an acquired dural-pial arteriovenous malformation (AVM) that developed after sinus thrombosis. The findings suggest AVMs can be acquired, not just congenital.
Area of Science:
- Neurology
- Vascular Surgery
Background:
- Reports an unusual case of acquired dural-pial arteriovenous malformation (AVM).
- The AVM developed following sinus thrombosis.
Observation:
- A 39-year-old man initially presented with superior sagittal sinus (SSS) and right transverse sinus (TS) thrombosis.
- Follow-up angiography showed sinus recanalization and retrograde cortical venous drainage.
- A dural-pial AVM developed near the site of sinus thrombi in cortical veins.
Findings:
- Demonstrates the development of a dural-pial AVM after sinus thrombosis.
- Complete surgical excision of the AVM was successful without neurological deficit.
Implications:
- Suggests that pial arteriovenous malformations (AVMs) can be acquired lesions.
- Challenges the notion that AVMs are exclusively congenital conditions.
- Highlights a potential link between sinus thrombosis and acquired AVM formation.
