Medications are given through an IV to calm the patient. This minimally invasive procedure uses tiny catheters to insert small coils directly into the aneurysm and close it from inside the vessel. The neurovascular surgeon makes a puncture in the patient’s leg and inserts the catheter, guiding it to the site of the aneurysm. The coil, along with a specialized glue, is positioned in place.
Often, the surgeon will pack several coils to fill the opening so that a clot can form and stop the bleeding.
In some cases, an intracranial stent may be used in aneurysms that are difficult to treat with coils alone. A stent (a flexible mesh tube that looks like a tiny chain-link fence) provides a protective support for the coils.
It depends on the complexity of the case and if multiple coils and a stent is used.
You will have to elevate your leg for several hours. Additionally, bleeding, breathing and heart rate will be monitored. Most patients are discharged the same day, but some are required to stay overnight.
You will feel better within a day, but you should refrain from driving, lifting or exercising until your doctor says it is OK.
