Endovascular Management of Intracranial Dural AVFs: Principles.

Area of Science:

• Neurology
• Vascular Surgery
• Interventional Radiology

Background:

• Intracranial dural arteriovenous fistulas (dAVFs) involve abnormal connections between dura mater arteries and cerebral veins/sinuses.
• These lesions are often a response to venous insults like thrombosis, trauma, or infection.
• Classification and management hinge on cortical venous drainage, a significant risk factor for hemorrhage and neurological deficits.

Purpose of the Study:

• To outline the principles and outcomes of endovascular treatment for intracranial dural arteriovenous fistulas.
• To provide an overview of endovascular management strategies for dAVFs.

Main Methods:

• Review of endovascular techniques for intracranial dAVF treatment.
• Discussion of patient selection criteria for intervention.
• Analysis of outcomes associated with endovascular approaches.

Main Results:

• Conservative management is suitable for dAVFs with mild symptoms and non-aggressive drainage.
• Intervention is indicated for intolerable symptoms, hemorrhage, or high-risk drainage patterns.
• Endovascular treatment options include transarterial embolization, transvenous embolization, or combined approaches.

Conclusions:

• Endovascular therapy offers a viable treatment option for select intracranial dural arteriovenous fistulas.
• The choice of treatment depends on fistula characteristics, symptoms, and risk factors.
• This article series focuses on the endovascular management of intracranial dAVFs.
