Stents Devices called stents are sometimes used in coiling. A stent is a small wire mesh tube that is placed inside the parent artery at the site of the aneurysm to cover the neck of the aneurysm, which helps keep the coil(s) inside the aneurysm sac. These devices can be particularly helpful for aneurysms with wide necks, or for large aneurysms that in the past were difficult to treat with an endovascular approach. The stents are usually made of nitinol, a high-grade metal alloy of nickel and titanium. The stent is placed in the same manner as the coils (via a catheter in an artery in the groin) at the time of the coiling procedure or sometimes as a separate treatment. If you have a stent placed, you will need to be on one or more antiplatelet (mild blood thinner) medicines such as aspirin, clopidogrel, or others for several weeks. Your doctor will review this with you Stent Aneurysm with stent in place. Coils put in place after stent. In some cases, a balloon is temporarily inserted to keep coils inside the aneurysm. Balloon 20
