Minimally invasive, image-guided procedures for selected conditions affecting the brain and blood vessels
Neuro-interventional radiology uses catheter-based techniques and advanced imaging to diagnose and treat certain conditions affecting the blood vessels of the brain and neck. These procedures can provide a minimally invasive approach when treatment inside the blood vessel is appropriate.
Dr. Yugal Goyal offers neuro-interventional services as part of his broader interventional radiology practice, with procedures focused on conditions such as acute ischemic stroke, cerebral aneurysms, vascular malformations and carotid artery disease.
An acute ischemic stroke occurs when a blood clot blocks an artery supplying the brain. In selected patients, rapid restoration of blood flow can be critical.
Mechanical thrombectomy is a catheter-based procedure used to remove a blood clot from a blocked blood vessel in selected patients with acute ischemic stroke.
A catheter is guided through the blood vessels to the site of the clot, where specialised devices are used to remove it and restore blood flow to the brain.
Treatment eligibility depends on factors such as the type of stroke, location of the blockage, time since symptoms began and imaging findings.
A cerebral aneurysm is a weakened area of a blood vessel in the brain that can bulge outward. Some aneurysms require treatment because of their risk of bleeding or other complications.
Endovascular coiling involves guiding a catheter into the aneurysm and placing small coils inside it. The coils help reduce blood flow into the aneurysm and promote clot formation within it.
A flow-diverting device is placed within the affected blood vessel to redirect blood flow away from the aneurysm. Over time, this can help reduce blood flow into the aneurysm.
The appropriate technique depends on the aneurysm's size, location, shape and other clinical factors.
An arteriovenous malformation (AVM) is an abnormal connection between arteries and veins. In selected cases, embolization can be used to reduce blood flow through the abnormal vessels.
A catheter is guided to the vessels supplying the AVM, where an embolic material may be delivered to block or reduce blood flow.
The carotid arteries supply blood to the brain. Narrowing of these arteries can reduce blood flow and may increase the risk of stroke.
Carotid artery stenting involves placing a stent within the narrowed artery to help maintain blood flow. It may be considered in selected patients after evaluation of the degree and location of narrowing and other individual risk factors.
Neuro-interventional procedures require detailed assessment of the brain and its blood vessels. Imaging helps identify the location and nature of a blockage, aneurysm or vascular abnormality and assists in planning treatment.
The choice of procedure depends on the specific condition, imaging findings, timing and the patient's overall clinical situation.
Neuro-interventional radiology is a specialised area of interventional radiology that uses image-guided, catheter-based procedures to treat selected conditions affecting the brain and its blood vessels.
Mechanical thrombectomy is a minimally invasive procedure used to remove certain blood clots from blocked brain arteries during an acute ischemic stroke.
Selected brain aneurysms can be treated using endovascular procedures such as coiling or flow diversion. Suitability depends on the individual aneurysm and the patient's condition.
AVM embolization is a catheter-based procedure that delivers embolic material to selected abnormal blood vessels to reduce or stop blood flow through an arteriovenous malformation.
Carotid artery stenting may be considered for selected patients with significant narrowing of the carotid artery. The decision depends on the degree of narrowing, symptoms, anatomy and other clinical factors.
