Clinical Background
Advanced Neurovascular Care Guided by Training, Research, and Compassion
Dr. Tigran Khachatryan, MD, PhD, is a fellowship-trained neurovascular and interventional neurologist with advanced training in the United States and Europe. His work focuses on precise diagnosis, minimally invasive treatment, and compassionate care for patients with neurological, cerebrovascular, and spine-related concerns.

Conditions Treated
Dr. Tigran Khachatryan evaluates complex neurovascular and spine-related conditions and offers minimally invasive, evidence-based treatment options when appropriate. Here are some of the most commonly treated conditions:
Unruptured Cerebral Aneurysm
A weak, bulging area in a brain artery that has not bled. Many cause no symptoms and are found on imaging. Cerebral angiography helps estimate rupture risk and whether monitoring or minimally invasive embolization is needed.
Arteriovenous Malformations (AVMs)
An abnormal tangle of blood vessels where arteries connect directly to veins, bypassing normal capillaries. Symptoms may include headaches, seizures, or neurologic deficits, and some AVMs carry a risk of intracranial hemorrhage, which can be life-threatening.
Dural Arteriovenous Fistula (DAVF)
An abnormal connection between arteries and veins located in the dura, the outermost membrane covering the brain. Symptoms vary and may include pulsatile tinnitus, headaches, vision changes, or neurologic deficits. Treatment options include minimally invasive endovascular therapy, surgery, or radiosurgery, depending on anatomy.
Venolymphatic Malformations of the Head and Neck
It is a non-cancerous cluster of abnormal veins and lymphatic channels in the soft tissues of the head or neck. It may cause swelling and pain. Sclerotherapy may be used to shrink the malformation in appropriate patients.
Chronic Subdural Hematoma
A gradually developing collection of blood on the brain’s surface, often after minor head trauma. Symptoms can include headache, confusion, imbalance, or weakness. A minimally invasive treatment, middle meningeal artery embolization may be considered after careful imaging reviews to prevent further blood buildup.
Acute Ischemic Stroke
Happens when a blood vessel supplying the brain is suddenly blocked (most often by a clot), causing part of the brain to lose blood flow and oxygen. Call 911 immediately. if you are experiencing sudden face drooping, arm weakness, speech trouble, severe imbalance, or sudden vision loss before scheduling a clinic appointment.
Brain Arteriovenous Malformation (AVM)
An abnormal tangle of blood vessels where arteries connect directly to veins, bypassing normal capillaries. Symptoms may include headaches, seizures, or neurologic deficits, and some AVMs carry a risk of intracranial hemorrhage, which can be life-threatening.
Carotid Artery Stenosis
Carotid artery stenosis is the narrowing of one or both carotid arteries in the neck, most commonly due to cholesterol plaque buildup. It can increase the risk of transient ischemic attack (TIA) or ischemic stroke. Treatment may include risk-factor control and medications, and in most cases, carotid endarterectomy or carotid artery stenting.
Idiopathic Intracranial Hypertension
Idiopathic intracranial hypertension (also called pseudotumor cerebri) is increased pressure inside the skull without a tumor or other structural cause identified. Common symptoms include daily headache, ringing in the ears, and sometimes double vision. Timely treatment is critical to prevent vision loss.
