5 things you should know about spider veins
If you have small, reddish-blue squiggly lines around your nose or on your legs, you probably have spider veins.
An endovascular stent graft is a woven fabric tube wrapped around a metal stent used to treat aortic aneurysms. Known as a stent-graft device, this minimally invasive approach is most commonly used to treat abdominal aortic aneurysms and thoracic aortic aneurysms (weakened bulges in the aortic wall). If not treated, both conditions can become life-threatening because of risk of rupture.
Endovascular stent grafts are an alternative to traditional open aortic repair, where an incision is made in the abdomen or chest to remove the aneurysm and replace it with a graft made of synthetic material. The best method for each aneurysm repair depends on factors such as the location and shape of the aneurysm and the overall health of the patient.
To determine if you are a candidate for endovascular stent graft, your doctor will perform a history and physical examination. You may also undergo some tests to evaluate your heart health as well as the size, shape and location of your aneurysm. These tests may include:
The vascular surgeons at Ohio State have extensive experience with traditional open repair of abdominal aortic aneurysms, including repair of complex cases. We also are experts at minimally invasive repairs and have experience in the use of all of the available stent graft technologies available to treat a wide variety of aneurysms.
Preparing for your procedure
Tell your doctor about all of the medications you are taking, including over-the-counter medications, and also if you are allergic to any medications or IV dye or contrast. You may be asked to discontinue glucophage or metformin if you are diabetic. You may be asked not to drink or eat anything for several hours prior to your procedure. If you are pregnant or if there is any possibility that you may be pregnant, inform your doctor.
During your procedure
You will receive a general anesthetic through an intravenous line inserted prior to the procedure. The area of catheter insertion will be shaved and cleaned.
Your doctor will make a small skin incision in the area of your groin. A long thin wire will be inserted into your femoral artery through the groin and guided to the area of the aneurysm. Using X-ray and contrast dye for guidance, a catheter is threaded over the wire. Another large catheter called a sheath is inserted. The sheath contains the graft stent that will be placed at the site of the aneurysm. When the graft reaches the aneurysm site, the sheath is withdrawn, the graft expands and is left in place.
After your procedure
Once the procedure is complete, you will be moved to a recovery room where your IV line will be removed. Your catheter site will be monitored for a period of time for bleeding and swelling. Your heart rate will also be monitored.
You will spend a couple of days in the hospital, during which time you will be asked to get up and walk. You will be able to eat normally. Your stent graft will be monitored periodically with imaging tests to be sure the stent is functioning.
