Minimally Invasive Treatment for Vascular Disorders of the Brain & Spine
Endovascular Neurosurgery is a sub-specialty within Neurosurgery that deals with vascular disorders of the head, neck, and spine, with treatment options from “inside” the blood vessel. In much the same way that interventional cardiologists treat heart disease in with minimally invasive techniques the cardiac cath lab, neurosurgeons can treat cerebrovascular diseases in the same manner. Endovascular Neurosurgery is also referred to as “neurointerventional surgery” or “interventional neuroradiology.”
In contrast to open surgery, where there is often a large incision in the head or neck, endovascular neurosurgeons treat vascular disorders of the head and neck with catheters that inserted in the femoral artery (the groin or leg). They can treat brain aneurysms, arteriovenous malformations, carotid artery stenosis, and acute stroke from inside the blood vessels.
DSA – Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. It is useful in the diagnosis and treatment of arterial and venous occlusions, including carotid artery stenosis, pulmonary embolisms, and acute limb ischaemia; arterial stenosis, which is particularly useful for potential kidney donors in detecting renal artery stenosis (DSA is the gold standard investigation for renal artery stenosis); cerebral aneurysms and arteriovenous malformations (AVM).
IA Thrombolysis – Intraarterial thrombolysis or IA thrombolysis can be effectively performed at our Cath lab which is used or the treatment of the patients who have suffered from an acute ischemic stroke. In this process, a specialised substance t-PA or tissue plasminogen activator is injected into the area of clot for the purpose of dissolving it.
Mechanical Thrombectomy – It is another of the procedure performed in our Cath lab for the treatment of the patients who had recently suffered from an acute stroke. This is performed only at the time a large blood vessel of the patient is blocked.
Carotid & vertebral artery and intracranial artery stenting – In this procedure, our expert doctors take a small balloon along with a very small metal scaffold called a stent for the purpose of opening a narrowed carotid artery which is responsible for supplying blood to the brain. Our well equipped Cath lab makes sure that the process is carried out at its best without any interruptions.
Aneurysm coiling – It is another vital treatment procedure carried out by our experienced doctors in the Cath lab where a thin metallic wire is inserted which forms a coil-like structure inside the brain aneurysm for blocking the flow of blood. Brain aneurysm is a bulged and weakened area in the artery wall in the brain which is at a great risk of bursting if not blocked.
AVM embolization – AVM is referred to as the arteriovenous malformations of the spine or the brain which is nothing but simply abnormal connections between the arteries and the veins. AVM embolization is a specialised technique performed in our Cath lab where the abnormal blood vessels are plugged out under x-ray guidance and with the help of a catheter from the femoral artery in the leg into the exact area of treatment.
Tumor embolization – It is a minimally invasive procedure in which a small, thin tube (catheter) is guided into the feeding arteries of a tumor in order either to shut down the blood supply to the tumor or deliver tumor-killing therapy directly to the tumor.
