Abdominal Aortic Aneurysm (AAA) Endovascular Stent Graft
Endovascular repair is a more cutting edge, minimally invasive procedure than the standard AAA repair. Endovascular repair of an abdominal aortic aneurysm is performed by inserting a catheter that contains an endovascular stent graft into the arteries of the groin. The catheter is advanced and placed inside the aneurysm. The graft is then expanded and held in place with metal hooks and by the pressure that the graft exerts against the wall of the aorta. X-ray guidance is used to properly position the graft within the aneurysm.
The purpose of the endovascular stent graft is to exclude blood flow to the aneurysm. When the graft is in the correct position, blood flow is through the graft and the aneurysm will no longer enlarge in size.
The procedure usually takes about two to three hours.
There is some risk with every medicalprocedure. The risk varies with each person, depending on the extent of the aneurysm disease and the type of procedure. Although rare, bleeding, blockage of the bypass graft, infection, heart problems, kidney failure, a reaction to the contrast dye, bowel ischemia and spinal cord ischemia may occur after surgery. These problems may require more surgery. Your surgeon will discuss the benefits and risks of your surgery.
Peripheral angioplasty is a procedure that has grown rapidly in recent years. The same atherosclerosis that involves the heart arteries can involve any artery in the body.
The most common arteries to be involved are those that supply the legs (causing cramps when walking, known as claudication), those to the brain known as the carotid arteries (causing strokes) and the arteries to the kidneys (causing high blood pressure).
The same risk factors for coronary artery disease are associated with peripheral vascular disease. Controlling these factors can help control symptoms.
There are noninvasive tests, which may help your doctor learn if the blood flow through the arteries is impeded and if so may order an angiogram. The procedure of peripheral angioplasty is performed using a catheter and a balloon to expand a narrowed artery. Stents are often used to help keep an artery opened. The procedure is performed under local anesthesia and sedation. The procedure of Peripheral Angioplasty can take 30 minutes to several hours depending on the number of blockages being treated.
Peripheral Angioplasty has a success rate of almost 95% with the chances of re-stenosis occurring in 5% of the patients. This procedure is less painful and allows you to go back to your daily activities quickly. This means that you will not have the symptoms of Peripheral Vascular Disease any more. Insertion of Drug Eluting Stents have potentially improved the clinical outcome of the procedure of Peripheral Angioplasty.
You may have your procedure as an outpatient or stay overnight. Light activity may be resumed shortly after the procedure and full activity in about one week.
