What is an AVM?

An AVM or arteriovenous malformation is a condition where the brain’s veins and arteries develop an abnormal connection causing the vessels to become tangled. An AVM goes unnoticed until the person starts showing symptoms like seizures, severe headaches and weakness (paralysis) of limb. If left unchecked, it can haemorrhage, which is often deadly.

What is an Aneurysm?

An aneurysm is a bulge in an artery in your brain caused by weakened arterial walls. It is a common condition, but it can be successfully treated if diagnosed in time. Most brain aneurysms are discovered when the artery bursts, which causes bleeding in the brain and its surrounding space called the subarachnoid. The primary goal in treating a ruptured aneurysm is to stop the bleeding and protect the patient from potential brain damage.

How are AVMs and Aneurysms treated?

Some AVMs and aneurysms are small and show a low risk of rupturing, so they do not require treatment. Surgery (Open Microscopic Assisted Endovascular) is required to treat those that possess a higher risk. In case of an aneurysm, the neurosurgeon will first perform a craniotomy where a section of your skull is removed. They will then place a clip across the weakened part of the artery which prevents blood flow into the aneurysm.

Another technique is called coil embolization and this is not as invasive as the craniotomy. The neurosurgeon will insert a catheter into the artery through your leg and navigate it toward the aneurysm. Through his/her catheter tiny platinum coils are inserted into the aneurysm, preventing blood flow and a potential rupture.

AVMs are also treated with similar techniques, but the doctor will determine the best way to tackle yourcondition based on its symptoms and severity.
