IMPORTANT NOTICE: At Fortis Healthcare, we are fully supportive of the National priorities set out by the Hon’ble Prime Minister of India. Further to the directives of the Government provided in their press release dated 8th Nov 2016, payments at Government hospitals can be made through 500 and 1000 Rupee denomination notes. In view of the hardship being caused to the large number of patients at private hospitals, we have made an urgent representation to the Government that this exemption should apply equally, for payments, at private hospitals. We are following up with the authorities and hope the Government will step in quickly to resolve this anomaly. Meanwhile, at Fortis hospitals across the country, we continue to accept payments through credit card, debit card and electronic banking transfers. As 500 and 1000 Rupee denomination notes are no longer legal tender we are only accepting 100 Rs and lower currency notes. As per Government regulation, a PAN card and legitimate ID proof is however required for payments in cash exceeding Rs 50,000. Meanwhile we continue to ensure that emergency cases get immediate medical attention without delay whatsoever and have put in more administrative staff and help desks to assist patients.

Brain AVM (arteriovenous malformation)

A brain AVM (arteriovenous malformation) is an abnormal connection between arteries and veins. An AVM is usually congenital, meaning it dates to birth.

An AVM can develop anywhere in your body but occurs most often in the brain or spine. A brain AVM, which appears as a tangle of abnormal arteries and veins, can occur in any part of your brain. The cause isn't clear.

You may not know you have a brain AVM until you experience symptoms, such as headaches or a seizure. In serious cases, the blood vessels rupture, causing bleeding in the brain (hemorrhage). Once diagnosed, a brain AVM can often be treated successfully.


Symptoms Causes Risk factors Complications

A brain AVM (arteriovenous malformation) may not cause any signs or symptoms until the AVM ruptures, resulting in bleeding in the brain (hemorrhage). However, some people with an AVM may have symptoms other than bleeding that are related to the AVM.

An AVM may also be detected on a brain scan performed for reasons unrelated to the AVM.

Symptoms of a brain AVM include:

  • Seizures
  • A whooshing sound (bruit) that can be heard on examination of the skull with a stethoscope or may be audible if you have an AVM
  • Headache
  • Progressive weakness or numbness

Some people may experience more-serious neurological symptoms, depending on the location of the AVM, including:

  • Severe headache
  • Weakness, numbness or paralysis
  • Vision loss
  • Difficulty speaking
  • Inability to understand others
  • Severe unsteadiness

Symptoms may begin at any age, but you're more likely to experience symptoms between ages 10 and 40. Brain AVM can damage brain tissue over time. The effects slowly build up, sometimes causing symptoms in early adulthood.

Once you reach middle age, however, brain AVMs tend to remain stable and are less likely to cause symptoms.

Some pregnant women may have worsened symptoms. However, it's not clear that pregnant women are at greater risk of an AVM bleeding. More research is needed to determine the risk during pregnancy.

When to see a doctor

Seek immediate medical attention if you notice any signs or symptoms of a brain AVM, such as seizures, headaches or other symptoms. A bleeding brain AVM is life-threatening and requires emergency medical attention.
