Dural Arteriovenous Fistula (DAVF) Treatment
Dural Arteriovenous Fistulae (DAVF) are abnormal connections between arteries and veins within the covering of the brain or spine. These abnormal high-flow connections can increase pressure inside veins and may lead to serious neurological complications if left untreated.
Common Symptoms
Patients may experience:
Persistent headache
Pulsating sound in the ear (Pulsatile Tinnitus)
Seizures
Weakness or stroke-like symptoms
Vision or cranial nerve problems
Intracranial bleeding
Neurological decline
Advanced Diagnosis & Imaging Technology
DAVFs are diagnosed using advanced neurovascular imaging techniques such as:
MRI / MRA Brain & Spine
CT Angiography
Digital Subtraction Angiography (DSA)
3D Rotational Angiography
Flat Panel Neuroangiography Technology
These latest imaging technologies help precisely identify abnormal blood flow patterns and assess the risk of bleeding.
Latest Minimally Invasive Treatment
Treatment is commonly performed using advanced endovascular neuro-interventional techniques under general anesthesia.
Modern Treatment Technologies Include:
High-resolution Biplane Neuroangiography Systems
Microcatheter Navigation Technology
ONYX & N-BCA Liquid Embolization
Transarterial Embolization
Transvenous Embolization
Real-time Fluoroscopic Guidance
A microcatheter is carefully guided to the fistula site, where specialized embolic agents are used to block the abnormal connection while preserving normal blood flow.
Benefits of Advanced Endovascular Treatment
Minimally invasive procedure
Reduced risk compared to open surgery
Faster recovery time
Precision-guided treatment
Improved safety and outcomes
Improved safety and outcomes
Some complex DAVFs may require staged treatment procedures and close neurocritical care monitoring.

Therapy / Treatment
Treatment depends on the location, blood flow pattern, and bleeding risk.
High-risk DAVFs are commonly treated using endovascular embolization.
A microcatheter is guided to the fistula site through the artery or vein.
Liquid embolic agents such as ONYX or N-BCA may be used to block abnormal flow.
Some complex cases may need staged treatment or surgery.
FAQs
Some DAVFs are low-risk, but those with backward flow into brain veins can cause bleeding or neurological problems.
Pulsatile tinnitus, headache, seizures, weakness, or sudden neurological symptoms need medical attention.
Yes. Many DAVFs can be treated through minimally invasive endovascular embolization.
