Endovascular neurosurgery is also called as interventional neuroradiology. It is a medical specialty, which is conducted minimally invasive technique for diagnostic procedures and therapeutic procedures conducted for the disorders related to the cerebrovascular. These procedures are performed under the guidance of radiology. It is somehow similar to the cardiology treatments, like stent placement or angioplasty.
Conditions for Performing the Surgery
- Spinal or Cerebral Angiography
- Stent Placement or Angioplasty
- Intracranial Aneurysms
- Arteriovenous Malformation
- Brain or Stroke attack, including Intra-Arterial Thrombolysis
- Vertebroplasty and Kyphoplasty
- Tumor Embolisation
- Percutaneous Sclerotherapy
Digital Subtraction Angiography is performed as a gold standard investigation for the blood vessels disease diagnosis. It is performed, if the vascular disease is found.
The condition of stent placement or angioplasty is done for treating stenosis present in the brain arteries that include intracranial and vertebral arteries. Such conditions can be well treated using endovascular route through non-invasive techniques. These procedures can be performed with the application of the local anesthesia and reduced morbidity.
Aneurysm is the focal swelling of the blood vessels in the brain. These blood vessels may burst and lead to the bleed in the brain. Such aneurysms can be treated through endovascular coiling, so that the open surgery is avoided. Coiling treatment has better outcomes than the open surgery.
AVM or Arterivenous Malformation is malformed and swollen blood vessels in the brain. This can cause brain to bleed, headache and seizures. This condition can be treated with onyx or glue injection with the help of the microcatheter that is to be placed in such abnormal blood vessels.
The condition of brain attack or acute stroke causes from arteries blockage in the brain. Such patients can be benefited by placing a micro-catheter at the bloackage site that has to be followed thrombolytic drug administration. This administration can dissolve the material that causes the block. When the patients come after the stroke, mechanical clots can be removed.
Bones becoming weak and further collapse with the growing age is called vertebrae in the spine. The condition results in severe back pain in the patient. Such conditions can be treated through vertebroplasty, which is performed by injecting the bone cement.
While intracranial tumour is being removed, the major problem is bleeding, while the surgery is performed. In such conditions, interventional neuroradiologist helps through preoperative blood vessels endovascular occlusion that supplies the tumour. Such processes can reduce the bleeding while the surgery is being peformed.
Haemangioma, lymphangiomas and many other vascular malformations can be well treated with needle puncture and then sclerosant material injection followed.
- The endovascular neurosurgery ensures no or minimal injury to the brain.
- The surgery has very fewer complications.
- Hospital stay will be shorter
- Outcome will be better
- The patients, who have gone through acute stroke can also be treated after several hours of occurrence of the stroke
Diagnostic and Therapeutic Procedures
Initially, therapeutic or diagnostic procedures are performed before deciding the surgery. These procedures sometimes supplement the regular and conventional surgery.
A very thin wire or catheter is taken and placed in the blood vessels in groin. These wires are then navigated towards the abnormal vessel site, in the blood vessels.
As the endovascular neurosurgery involves only minimally invasive procedures, the outcomes are better and recovery becomes shorter. Neurointerventions are crucial in both the diagnosis procedure and management of stenosis of arteries like carotid arteries, brain aneurysms, arteriovenous malformations and acute ischaemic stroke.
