Minimally invasive procedures to treat brain and spine conditions using advanced imaging guidance, offering precise treatment with faster recovery times.
Interventional Neuroradiology is a highly specialized medical field that focuses on the minimally invasive diagnosis and treatment of conditions affecting the brain, spine, head, and neck using advanced imaging guidance. This specialty combines expertise in neurology, neurosurgery, and radiology to treat complex vascular and neurological disorders without the need for traditional open surgery in many cases. By using image-guided techniques, specialists can access delicate areas of the nervous system through tiny catheters inserted into blood vessels, offering safer and more precise treatment options.
Interventional neuroradiology is commonly used to treat a variety of conditions involving the blood vessels of the brain & spinal cord. These include brain aneurysms, arteriovenous malformations (AVMs), stroke caused by blocked blood vessels, carotid artery disease, and other vascular abnormalities. The specialty also plays a role in the management of certain tumors, spinal conditions, and chronic pain disorders related to the nervous system. Because these conditions can have serious or life-threatening consequences, rapid diagnosis and treatment are often critical.
Diagnosis and treatment in interventional neuroradiology rely heavily on advanced imaging technologies such as CT scans, MRI, and digital subtraction angiography (DSA). These imaging techniques allow specialists to visualize the brain’s blood vessels and nervous structures in great detail. Using this real-time imaging guidance, doctors can navigate microcatheters through the body’s vascular system to reach the affected area with exceptional precision.
Treatment procedures performed in this field are typically minimally invasive and may include techniques such as embolization to block abnormal blood vessels, placement of coils or stents to repair aneurysms, and mechanical thrombectomy to remove blood clots during acute stroke. These procedures are usually performed through small punctures in the skin, reducing the need for large surgical incisions.
With advances in imaging technology and minimally invasive techniques, interventional neuroradiology has significantly improved the treatment of many complex neurological conditions. Patients often benefit from shorter hospital stays, faster recovery, and reduced surgical risks while receiving highly specialized care for disorders affecting the brain and spine.

Mechanical thrombectomy is an emergency procedure that removes a blood clot from a blocked artery in the brain to treat acute ischaemic stroke. A catheter is guided to the clot and a special device pulls or suctions it out, restoring blood flow. Recovery and rehabilitation continue for weeks to months.

Flow diverter placement is a minimally invasive endovascular procedure used to treat certain brain aneurysms, particularly large, wide-necked, or complex ones. A fine mesh tube is placed inside the parent artery to redirect blood flow away from the aneurysm, allowing it to clot off and heal over months.

AVM embolization is a minimally invasive endovascular procedure used to block abnormal connections between arteries and veins, most often in the brain. It can be a standalone treatment or part of a planned strategy with microsurgery or radiosurgery, depending on the AVM's size, location, and bleeding risk.

Carotid artery stenting (CAS) is a minimally invasive procedure that opens a narrowed carotid artery in the neck using a small mesh tube called a stent. It is used to reduce the risk of stroke in people with significant carotid artery disease, and is one of two main procedural options alongside carotid endarterectomy surgery.

Dural arteriovenous fistula (DAVF) embolization is a minimally invasive, catheter-based procedure that closes abnormal connections between arteries and veins in the dura, the tough covering around the brain or spinal cord. It is used to relieve symptoms and reduce the risk of bleeding or progressive neurological problems.

Intracranial aneurysm coiling is a minimally invasive endovascular procedure that seals a brain aneurysm from inside the blood vessel using soft platinum coils. It is used to prevent rupture or to stop bleeding after rupture, and is one of several treatment options doctors may consider depending on the aneurysm.

Intracranial arterial stenting is a minimally invasive procedure that places a small mesh tube inside a severely narrowed artery in the brain to keep it open and improve blood flow. It is considered in carefully selected patients at high risk of stroke when intensive medical therapy is not enough.

Pediatric vascular malformation embolization is a minimally invasive procedure that closes off abnormal blood vessels in a child's brain, spine, or other tissues using tiny catheters guided by live imaging. It is used to treat conditions such as brain AVMs, Vein of Galen malformations, and dural arteriovenous fistulas, and is often performed in stages.
