What is endovascular coiling?

Endovascular coiling is a minimally invasive procedure that can be used to treat a brain aneurysm.

What to expect

Endovascular coiling requires the insertion of a catheter into the femoral artery in the leg. Your doctor will use real time X-ray guidance to navigate the catheter through your blood vessels and into the aneurysm. Soft platinum coils are then threaded through the catheter and inserted into the aneurysm. These coils conform to the shape of your aneurysm, fill the sac and block blood flow to prevent the aneurysm from rupturing. You will receive general anesthesia or light sedation for this procedure.

Recovery

Patients typically stay in the hospital for two to four days to prepare and recover, and then it may take an additional week or so to recover at home. If your aneurysm is complicated, or if it has bled, your hospital stay and recovery period may be longer.
