Brain aneurysm is the bulging or ballooning of a blood vessel supplying the brain. Brain aneurysms are present in 1 to 2% of the population. Those aged 40-60 years are most likely to be affected.

The most serious complication is bursting or rupture of the aneurysm that leads to severe sudden episodes of headache and immediate death in up to 20% of affected patients. In the remaining affected population, it leads to serious haemorrhagic stroke that is potentially debilitating if left untreated.
Some of the known risk factors include:
- Family history
- Polycystic kidney disease
- Age over 50 years.
A simple CT scan or an MRI scan is all that is needed to diagnose a brain aneurysm and plan treatment.
Brain aneurysms are a treatable condition and the best time to treat it is before it ruptures.
Coiling is a minimally invasive technique and a common alternative to the traditional open surgery method of clipping.
- Coiling may be balloon or stent assisted.
- Another method is to use a special flow diverter stent to treat the aneurysm.
- Involves a small incision in the groin to access a blood vessel.
- Small catheters and wires are put through the incision and directed to the brain to block off the aneurysm.
- The treatment time and length of recovery period are both much shorter than open surgery (1-2 days if the aneurysm is unruptured).
