Intra-arterial treatment for Acute Ischemic Stroke (AIS)

Ischemic Stroke is the most common type and accounts for 87% of all strokes. [1] It occurs due to blockage of blood vessel usually by a blood clot or by fatty deposits. In treatment of Acute Ischemic Stroke (AIS), the primary goal is to quickly restore blood flow by dissolving the clot through clot bursting medication or by physically removing the clot through intra-arterial treatment.

Brain Aneurysm Coil Embolization

An aneurysm is an outpouching or ballooning of a weakened part of a blood vessel. Aneurysms can occur in any part of the body where there is a weak vessel. Brain aneurysms also called Intracranial Aneurysms are the most life threatening as they pose greater risk of rupture if left untreated and bleeding into the brain causing hemorrhagic stroke. In 5 year follow up, the overall risk of rupture of untreated aneurysm is 1.2%. [1]

Brain Aneurysm Flow Diverting Stent Placement

Brain aneurysm, based on the location and size, can also be treated endovascularly by a device called Flow diverter. It is a stent like device which can be placed in the parent vessel across the neck of aneurysm to divert the blood flow away from the aneurysm.

Brain & Spine Arteriovenous Malformation (AVM) Embolization

An Arteriovenous Malformation or AVM is an abnormal tangle of blood vessel connecting an artery to a vein. An AVM can develop anywhere in the body but occurs most often in the brain or spine.

Brain & Spine Arteriovenous Fistulas (AVF) Embolization

Arteriovenous Fistula (AVF) is an abnormal connection between an artery and a vein. The normal blood circulation involves flow of blood from artery to capillaries to a vein. With an AV fistula, capillaries are bypassed making a direct flow between an artery and a vein which ultimately reduces the blood supply to the tissues otherwise supplied by the normal capillaries.

Carotid Artery Stenting & Angioplasty

Carotid arteries are the major blood vessel, one on each side of neck that supply the blood to the brain. These carotid arteries can be narrowed (stenosis) due to buildup of plaque inside their lumen, reducing the blood supply of brain and increasing the future likelihood of stroke.

Epistaxis Embolization

Epistaxis (or Nosebleed) is defined as bleeding from the nose which occurs due to burst of a blood vessel within the nose. The nasal cavity has a rich blood supply from both internal and external carotid arteries. More than 90% of nosebleeds occur from the anterior part of the nose in an area known as littleā€™s area which is extremely vascular.

Head, Neck & Spine Tumor Embolization

Tumor embolization is an important adjunctive therapy for head, neck and spine tumor management. Tumor embolization is done by endovascular technique which is minimally invasive and it blocks the blood supply to the tumor. In most instances, it is reserved for highly vascularized tumors and it is performed as a preparation for later surgical resection of the tumor.

Kyphoplasty for Compression Fractures

Compression fracture of vertebra is the collapse of vertebral body of spine. These compression fractures of thoracolumbar spine are the most common in elderly and occur in approximately 25% of all postmenopausal women during their lifetime in United States.

Dural sinus stent placement for Idiopathic Intracranial Hypertension (pseudo-tumor -cerebri)

Idiopathic Intracranial Hypertension (IIH) which is also called Pseudotumor cerebri is an uncommon condition, associated with increases intracranial pressure. It mostly affects young obese females. The most common symptoms include headache, visual disturbance and tinnitus (ringing sound in the ear).

Diagnostic Cerebral & Spinal Angiogram

Diagnostic cerebral and spinal angiogram is a minimally invasive diagnostic test which is used to acquire high resolution images of blood vessels of brain and spinal cord. It serves as a definitive diagnostic test to detect or confirm many abnormalities of blood vessels of brain.

Dural Arteriovenous Fistula (DAVF): Craniotomy for Closure

Dural arteriovenous fistulas (DAVFs) are defined as direct shunts between arteries and venous sinuses or cortical veins with no transitional capillary network contained within the leaflets of the dura mater, the thick layer of the meninges that covers the brain. They are supplied by branches of the carotid and vertebral arteries before they penetrate the dura.

Cerebral Vascular Insufficiency: Direct & In-direct By-pass

Cerebral artery bypass is utilized for mainly 4 categories: complex aneurysms that are not amenable to clipping or coiling, atherosclerotic narrowing of vessels leading to too little blood flow to the brain, Moyamoya disease, and tumor-invaded important vessels where blood flow to the brain needs to be maintained.

Carotid Stenosis: Carotid Endarterectomy (CEA)

Carotid artery atherosclerosis begins to form at 20 years of age. Plaques tend to grow on the back wall of the common carotid artery (CCA) and then encroach on the lumen of the Internal Carotid Artery (ICA) as they enlarge with time. Carotid artery stenosis may be asymptomatic or symptomatic.
