Summary:
The authors report the observation of a patient with a Spetzler-Martin grade 3, symptomatic, sulcal cerebral arteriovenous malformation (cAVM) of the left precuneus that after partial, uncomplicated, endovascular embolisation disappeared at 4, 6 and 12 months follow-up. Discussion focuses on the angioarchitectural remodelling of the cAVM over time according to the latest concepts on AVM development and evolution.
Insights
A symptomatic cerebral arteriovenous malformation (cAVM) resolved after embolization. This case study highlights the potential for angioarchitectural remodeling and spontaneous resolution of cAVMs following endovascular treatment.
Area of Science:
- Neurology
- Neurosurgery
- Interventional Radiology
Background:
- Cerebral arteriovenous malformations (cAVMs) are complex vascular lesions.
- Symptomatic cAVMs pose a significant risk of hemorrhage.
- Spetzler-Martin grade 3 cAVMs are associated with higher surgical risks.
Purpose of the Study:
- To report a unique case of a Spetzler-Martin grade 3 cAVM.
- To describe the outcome of endovascular embolization for a symptomatic sulcal cAVM.
- To discuss the angioarchitectural changes and potential for resolution of cAVMs.
Main Methods:
- A patient with a symptomatic Spetzler-Martin grade 3 sulcal cAVM was treated.
- Partial, uncomplicated endovascular embolization was performed.
- Serial imaging follow-up at 4, 6, and 12 months was conducted.
Main Results:
- The treated cerebral arteriovenous malformation (cAVM) showed complete resolution.
- Resolution was confirmed at 4, 6, and 12 months post-embolization.
- The procedure was uncomplicated.
Conclusions:
- Endovascular embolization can lead to the disappearance of complex cAVMs.
- Angioarchitectural remodeling and potential spontaneous resolution are key considerations in cAVM management.
- This case contributes to understanding cAVM evolution after treatment.
