1. Clinical assessment
Through medical history taking and neurological examination, clinicians evaluate seizures, history of hemorrhage, and neurological status.
2. Cranial CT and CTA
CT is used for rapid identification of acute hemorrhage, while CTA can preliminarily demonstrate abnormal vascular structures, providing a basis for emergency management.
3. MRI and MRA
MRI helps assess the relationship between the nidus and eloquent brain regions, while MRA can serve as a noninvasive vascular screening tool.
4. Digital subtraction angiography (DSA)
By dynamically visualizing blood flow, DSA delineates feeding arteries, nidus architecture, and venous drainage patterns, and is a key examination for grading assessment and treatment planning.
5. Grading and risk assessment
Spetzler–Martin grading is performed in conjunction with imaging findings to provide an evidence-based basis for selecting treatment modalities.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that accurate diagnosis is the foundation of brain arteriovenous malformation management. Standardized imaging workflows and systematic assessment enable the development of safer and more appropriate individualized treatment plans for patients.
