An aneurysm is a weak, bulging area in the wall of a brain artery. If it ruptures, it causes bleeding around the brain, which is life-threatening. Treatment aims to seal the aneurysm to prevent bleeding, either by clipping through open surgery or by coiling through a catheter.

At Apex, assessment starts with CT and cerebral angiography, which show the size, shape and neck of the aneurysm. The team considers the patient's age, condition, whether it has ruptured and the position of the aneurysm to choose the safer method. In clipping, the surgeon opens the skull, uses the microscope to reach the aneurysm and places a small metal clip across its neck. In coiling, a catheter is passed through an artery to the aneurysm, and soft platinum coils are packed inside it.

Patients are monitored in intensive care after treatment, with careful control of blood pressure and fluid balance. Follow-up imaging checks that the aneurysm remains closed.

How the Procedure Can Help

Treatment greatly reduces the risk of rupture or repeat bleeding. Coiling usually involves a shorter recovery, while clipping may give a more durable result for some aneurysms.

Risks and Considerations

Risks include bleeding, stroke from a blocked vessel, brain swelling, infection and, after coiling, the need for repeat treatment if the aneurysm reopens. Sudden severe headache, weakness, speech difficulty or drowsiness afterwards needs emergency care.
