Brain Aneurysm Coiling Treatment
Brain aneurysm coiling is a minimally invasive endovascular procedure used to treat certain brain aneurysms and reduce the risk of bleeding or rupture. Instead of opening the skull, a specialist guides a thin catheter through a blood vessel, usually from the groin or wrist, toward the aneurysm. Tiny platinum coils are then placed inside the aneurysm to promote clotting and prevent blood from entering it.
When Is Brain Aneurysm Coiling Recommended?
Cerebral aneurysm coiling may be considered for selected ruptured or unruptured brain aneurysms, depending on factors such as aneurysm size, location, shape, overall health, and risk of rupture. A neurosurgical or neurointerventional team evaluates brain imaging and medical history before recommending treatment.
What Does the Procedure Involve?
The procedure is generally performed under appropriate anesthesia with continuous imaging guidance. The catheter is carefully positioned inside the aneurysm, and detachable coils are deployed to block blood flow into the aneurysm. In some cases, additional devices such as a balloon or stent may be required to support coil placement.
Benefits and Recovery
The minimally invasive approach may avoid the need for traditional open brain surgery in suitable patients. Recovery varies depending on whether the aneurysm was ruptured, the patient's neurological condition, and the complexity of treatment. Follow-up imaging may be recommended to monitor the treated aneurysm.
Patients should discuss potential benefits, risks, alternatives, and follow-up requirements with their treating specialist before proceeding.
