Interventional or Endovascular Medicine
Interventional medical practitioners are specialists who treat diseases of the blood vessels of the brain (cerebrovascular) via minimally invasive procedures, instead of fully open neurosurgery. These procedures cause less operative trauma (less pain and scarring) and therefore allow significantly quicker recovery times, lower risks of infection and lower incidence of post-surgical complications; this makes it possible for higher risk group patients, such as senior citizens, to undergo complex procedures.

For over a decade, our hospital has been suitably equipped to handle all complex neurovascular interventions. In addition to this, our cardiology department has Cardiac interventionalists skilled enough to treating exceedingly complex conditions such as cardiac ischemia and atherosclerotic vascular disease. With faster paced lifestyles and higher comfort standards in medicine; interventional medicine is becoming highly sought after. In a hospital like ours, where progress is the norm, minimally invasive neurological procedures and neuro interventions contribute to available medical expertise.

Neurointervention
A cerebral angiography is an angiogram of the brain vessels, just as a coronary angiography is an angiogram of the heart. This procedure is done under local anesthesia via the groin (femoral artery) and small catheters are placed into the carotid and vertebral arteries of the brain, then a dye (contrast) is injected to study the vascular tree of the brain.

Our neurointerventionalists are skilled at treating:
  • Acute Ischemic strokes
  • Hemorrhagic strokes
  • Carotid artery stenosis (Carotid Stenting)
  • Vertebral stenosis (Vertebral stenting)
  • Basilar stenosis (Basilar stenting)
  • Cerebral aneurysms (both ruptured and unruptured by Coiling)
  • Cerebral and spinal arteriovenous malformations (AVMEmbolizations)
  • Dural cerebral and spinal arteriovenous fistulas (Dural AVF)
  • Acute Vascular trauma
  • Epistaxis( Bleeding from nose)
  • Vertebroplasty( strengthening vertebral bodies)
  • Tumours of the head and neck (preoperative embolization)
Some commonly carried out procedures are:
Coiling of aneurysms: Aneurysms are balloon like weak areas in brain arteries and when they rupture they lead to severe bleeding in the brain. They require treatment at the earliest by packing the aneurysms with coils and other endovascular techniques.

Carotid and Intracranial stenting: Stents are placed in narrowed arteries that cause recurrent stroke. Stents help restore the caliber and prevent repeated strokes or paralytic attacks.

Embolization of AVMs and Tumours: AVMs are a mesh of abnormal vessels which can lead to dangerous brain hemorrhage. Obliterating the AVM is done with Onyx or glue. Preoperative embolization of vascular brain tumours helps the neurosurgeon by decreasing blood loss during surgery

Acute Stroke Therapy: deals with opening the blocked brain arteries with drugs or devices and then supplying blood to the brain tissue. This has to be done within the first few hrs of stroke.

With the advent of minimally invasive neuro intervention, previously untreatable neurological conditions can easily be managed. The same can be said of patients who fall into the 'high risk' bracket.
