Neurointervention or Endovascular Neurosurgery is a modern evolution in Neurosciences to treat various vascular diseases of the brain and spinal cord. It is Minimally Invasive Therapy where catheters are advanced into brain or spinal cord through a tiny needle puncture in groin to diagnose & treat the lesion.

At Yatharth Centre for Neurosciences we have a fully equipped Neuro Intervention setup with complete backup of Neurosurgery and Neurocritical care teams. At Yatharth, we have advanced infrastructure including:

• Dedicated cath lab for doing all routine or emergency Neurointervention procedures.
• Dedicated Stroke/Neuro ICU for care of these patients
• Dedicated fully equipped neurosurgical theatre for any neurovascular emergency

Spectrum Of Endovascular Neurosurgery

Aneurysm Coiling

Endovascular coiling is a procedure performed to block blood flow into an aneurysm (a weakened area in the wall of an artery), which is source of brain hemorrhage. Endovascular coiling is a more recent treatment for brain aneurysms; it has been used in patients since 1991 & since then it has undergone constant improvement in safety and available devices.

Endovascular coiling is a minimally invasive technique, which means an incision in the skull is not required to treat the brain aneurysm. Rather, a catheter is used to reach the aneurysm in the brain.

During endovascular coiling, a catheter is passed through the groin up into the artery containing the aneurysm. Platinum coils are then released. The coils induce clotting (embolization) of the aneurysm and, in this way, prevent blood from getting into it.

Flow Diverter Placement

This is a recent advancement to treat complex aneurysms.

AVM Embolization

Arterio-venous malformation (AVM) of brain & spinal cord is an abnormal conglomerate of vessels which have weak wall & is a source of brain/spinal cord hemorrhage. AVM embolization reduces the number of abnormal connections between blood vessels that occur in the brain. 

Other modalities to treat these lesions include surgery, and endovascular embolization.

Endovascular Embolization

Endovascular Embolization involves the injection of glue or other non-reactive liquid adhesive material into the AVM in order to block it off and thereby obliterating the source of bleeding. For this purpose, a small catheter is passed through a groin vessel all the way up into the blood vessels supplying the AVM & thus a bigger cut on the skull is avoided.

Acute Stroke

Endovascular therapy has made a significant contribution in treatment of acute ischemic stroke. Acute stroke is a catastrophic condition where the blood supply to the brain is hampered due to block in the arteries supplying the brain. In such situation the interventionist take the device directly to the point of blockage and removes the clot and restores the supply to the brain and avoiding permanent paralysis or death.

Carotid Stenting

Carotid arteries are the main arteries supplying the brain. Similar to the coronary arteries (heart vessels) that get blocked due to deposition of cholesterol, carotid arteries are also susceptible to blockage and thus leading to stroke or TIA (transient ischemic attack- warning stroke). Timely detection of these blocks is important. With Endovascular therapy they can be opened by placing stents across the lesion and thereby maintaining flow to the brain.

Intracranial Stenting

In certain situations where the arteries inside the brain get narrowed and blocked and is the reason for developing recurrent stroke, the stents can be placed even in these small brain arteries to keep them patent and reduce the chances of stroke.

Tumor Embolization

Endovascular therapy is also used to reduce the blood supply to the tumors of brain, nose and face thereby helping the surgical colleagues by reducing the blood loss during the surgery and making the surgery safer and faster.

Spinal Angiography

There are certain conditions of spine which can be diagnosed only by doing angiography of spine. Spinal angiography is a technically demanding procedure where multiple arteries supplying the spinal cord are entered and dye is injected in each of them to see the abnormality and plan the treatment. These lesions can then be further treated by advance Endovascular treatments.

Neurointervention today has become an integral part of any advances neuroscience centre and besides treating above conditions, it is of immense help in treating other situations like carotid - cavernous fistula, nasal bleeding etc.
