Summary
Digital subtraction angiography (DSA) detected intracranial vascular malformations in 4% of cervicocranial examinations. While DSA can identify major findings, selective angiography is better for detailed diagnosis, especially for small or pre-operative cases.
Area of Science:
- Neurology
- Radiology
- Vascular Surgery
Background:
- Cervicocranial vascular malformations require accurate diagnostic imaging.
- Digital subtraction angiography (DSA) is a key tool for visualizing these conditions.
Purpose of the Study:
- To evaluate the diagnostic yield of DSA in detecting cervicocranial intracranial vascular malformations.
- To compare the effectiveness of different DSA approaches for diagnosis.
Main Methods:
- Retrospective analysis of 350 DSA examinations in the cervicocranial region.
- Categorization of detected vascular malformations (aneurysm, arteriovenous, venous).
- Comparison of intravenous/intra-aortal versus selective DSA techniques.
Main Results:
- Intracranial vascular malformations were identified in 14 patients (4% of 350 examinations).
- Detected malformations included aneurysms (6), arteriovenous malformations (6), and venous malformations (2).
- Intravenous/intra-aortal DSA was sufficient for major findings, but selective DSA provided more detailed diagnostic information.
Conclusions:
- DSA is effective in detecting cervicocranial intracranial vascular malformations.
- Selective DSA is superior to non-selective methods for detailed pre-operative and small lesion diagnosis.
