Coiling, or endovascular embolization, consists of placing micro-coils in an aneurysm via a catheter to close off blood flow and thus prevent rupture or stop bleeding. Micro-coils are shaped like a spring and made of platinum. They are tiny, ranging in size from about twice the width of a human hair to less than one hair's width. Coiling does not require a craniotomy and is performed under light sedation or general anesthesia. Generally, the hospital stay (1-3 days) is half that of more invasive procedures.
Stenting is performed by placing a pipe-shaped metal mesh inside the blood vessel to cover the neck of the aneurysm. The stent is placed before coiling and remains in the artery permanently to hold the coils inside the aneurysm, preventing them from falling out. Over time, blood clots on the coils and diverts blood away from the weakened vessel walls and prevents a rupture.
During a mechanical thrombectomy, the surgeon removes the clot that is obstructing blood flow to the brain using sophisticated instruments called retriever devices. The procedure starts with inserting a catheter into an artery in the leg, which is then guided through the vascular system into the obstructed vessel in the brain. The clot retrieval device is then passed through the catheter to the blood clot, where it captures and removes it.
A craniotomy is an intricate neurological procedure performed by opening the skull, performing the needed operation and closing the skull by securing the bone into its original position. We offer our patients the best care and access to neurosurgical innovations that you only see at leading academic medical centers.
