Arteriovenous Malformation (AVM) Surgery

Arteriovenous Malformation (AVM) Surgery Treatment In EM Bypass, Kolkata

An arteriovenous malformation (AVM) is an abnormal tangle of blood vessels (nidus) that connects cerebral arteries, i.e., those carrying oxygen‑rich blood, directly to cerebral veins, i.e., those that return oxygen‑poor blood. At Manipal Hospitals, our neurosurgery team combines advanced techniques to perform Arteriovenous Malformation (AVM) Surgery Treatment in EM Bypass, Kolkata, safely and effectively. 

How Does Arteriovenous Malformation (AVM) Occur? 

In a normal person, cerebral arteries carry oxygen-rich blood to the brain. Capillaries, located between arteries and veins, allow a slow and steady flow of blood to brain cells for oxygen and nutrient exchange. Cerebral veins then return oxygen-poor blood to the heart.

In AVM, cerebral arteries connect directly to cerebral veins, bypassing the capillaries. This forms a tangled mass of vessels called the nidus. As blood flows rapidly and at high pressure through the nidus, veins struggle to handle it, often leading to rupture, bleeding, or stroke.

Preparation: 

Before performing the Arteriovenous Malformation (AVM) Surgery Procedure in EM Bypass, Kolkata, our surgeons will use high-precision neuroimaging methods to locate AVMs. Common instructions for preparation include:

  • Fasting from food and beverages for a certain period

  • Discussing current medications, especially anti-coagulants and anti-seizure drugs

  • Being aware of the procedure, side effects, and recovery

  • Making personal adjustments for the surgery

Procedure:

At Manipal Hospitals, patients undergoing Arteriovenous Malformation (AVM) Surgery Treatment in EM Bypass, Kolkata, are initially administered anaesthesia. Depending on the type of procedure, one or a combination of these is performed:

  • Microsurgical Resection: Involves the surgical removal of the nidus using a high-powered microscope. Doctors temporarily open the skull to access the brain (Craniotomy) and remove the AVMs carefully. 

  • Endovascular Embolisation: A catheter is introduced into the artery via the groin or wrist, followed by positioning it on the cerebral artery that feeds the AVM. The process is done using X-ray imaging. Embolising agents are given to block the blood flow to the AVM. 

  • Stereotactic Radiosurgery (SRS): Uses precise, focused radiation, e.g., Gamma Knife®, to destroy the AVM. Usually, doctors perform this procedure for AVMs that surgery cannot remove and that have not caused dangerous bleeding. 

In the case of surgery, the embolisation technique is sometimes used to block the blood supply to the AVM. The step is done to reduce blood loss. On the other hand, Stereotactic Radiation is noninvasive and targets AVM from outside the skull.

After Procedure:  

Recovery is closely monitored in the Neuro‑ICU at Manipal Hospitals after undergoing Arteriovenous Malformation (AVM) Surgery Procedure in EM Bypass, Kolkata:

  • Doctors and nurses closely observe the patient for any post-operative complications

  • A follow‑up CT or MRI within 24 hours to confirm nidus removal and rule out bleeding.

  • Rehabilitation is recommended to help you gain strength and balance

FAQ's

Some of the risks include excessive bleeding after surgery, problems in speech or vision, weakness, seizures, infection at the incision site, brain swelling (hydrocephalus), and, in rare cases, anaesthesia adverse events.
 

Your expected recovery duration is based on several factors, including the type of surgery performed, the severity of your condition, and your overall health. In most cases, you can recover partially and carry out routine activities within 4–6 weeks. Complete recovery can take months. This can, however, vary. 
 

You should keep in mind that adequate rest is needed during your initial recovery days. You will have to restrict your activity for several weeks. Moreover, you can expect some discomfort in the incision site. It is necessary to adhere to follow-up care, as well as diet, medication, and rehabilitation exercises for easy recovery.

Sudden severe headache, stroke‑like weakness, seizures, or vision/speech changes warrant immediate emergency care, as they may signal AVM rupture.  
 

No, since the cause is known, we cannot prevent brain AVMs. It can happen at any stage of life. It is best to seek immediate care if you experience any symptoms that may indicate brain AVMs.
