The University of Michigan Frankel Cardiovascular Center offers both open heart surgery and minimally invasive treatments for aortic aneurysm.
University of Michigan Frankel Cardiovascular Center Aortic Disease program began in 1995 and has a long history of treating all types of aortic disease.
Aortoiliac occlusive disease (AIOD) is common in patients with PAD. AIOD is the blockage of the aorta, the main blood vessel in your body, or the iliac arteries. The aorta divides into the iliac arteries, which provide blood to the legs and organs in your pelvis. This blockage is typically caused by a buildup of plaque within the walls of the blood vessels.
Arterial disease, sometimes called artery disease, is a vascular disease that affects the arteries of your body, which are the vessels that carry oxygen-rich blood away from your heart to the tissues of the body. The largest artery in your body is the aorta, which stems from the heart’s left ventricle and branches out into smaller arteries throughout the body. Arterial diseases include: aortic aneurysms, peripheral arterial disease (PAD), and thoracic outlet syndrome (TOS).
University of Michigan Aortic Disease Program treats all kinds of arterial disease, including arteriosclerotic aortic disease (hardening of the arteries).
Cerebrovascular disease refers to a group of conditions that affect blood flow and the blood vessels in the brain. Problems with blood flow may occur from blood vessels narrowing (stenosis), clot formation (thrombosis), artery blockage (embolism) or blood vessel rupture (hemorrhage). Lack of sufficient blood flow (also referred to as ischemia) affects brain tissue and may cause a stroke.
Chronic venous insufficiency (CVI) is a disease that occurs when superficial or deep veins or not working properly. Patients with CVI often have painful or swollen legs and may develop darkened skin, sores (ulcer) and varicose veins. CVI affects women more than men and is increasingly common over age 50.
Deep vein thrombosis, commonly referred to as DVT, is a condition that results from the formation of a thrombus, or blood clot, in a vein deep within the body. In addition to causing leg pain and swelling, the condition also can be complicated by pulmonary embolus (PE) should a piece of clot break loose and travel into the pulmonary (lung) circulation. A PE can seriously impair breathing (oxygenation), stress the heart, and can result in death.
Endovascular aneurysm repair (EVAR) is a preferred treatment for many abdominal aortic aneurysm patients and an alternative for some who do not qualify for open surgery. Compared with open AAA repair, minimally invasive EVAR is associated with a significant reduction in mortality, primarily because EVAR does not require exposure of the aorta. EVAR also results in a shorter hospital stay and faster recovery time.
Patients diagnosed with an enlarged aorta will likely have many questions about the condition: How big is too big? When should I be worried? What does “watchful waiting” mean? Are there any early warning signs before it bursts? Most of the answers to these questions depend on a variety of factors, including age and body size, medical history, and the position and size of the aorta, among others.
The Fenestrated Endograft (FEVAR) is a relatively new minimally-invasive option for people with abdominal aortic aneurysms who don’t qualify for traditional endovascular aneurysm repair (EVAR). The unique feature of fenestrated endografts is that they can cover branch arteries of the aorta (such as the renal arteries) because the graft has fenestrations, or holes, that correspond to the position of the branching arteries within the aorta to allow for blood to flow through the graft into the branch vessel.
Fibromuscular dysplasia (FMD) is a vascular disease that causes abnormal cell development in the walls of one or more arteries. This can put individuals at risk for artery blockages, stroke, artery dissection (tear in an artery) or aneurysm (artery bulge).
Hemodialysis is a treatment that purifies the blood of a person whose kidneys have failed. This treatment involves a machine used to route a patient’s blood through a filter, called a dialyzer, outside the body. The two types of vascular access for patients on long-term hemodialysis include arteriovenous (AV) fistula and arteriovenous (AV) graft.
Mesenteric vascular disease is a condition that develops when the arteries in the abdomen that supply the intestines with blood become narrowed due to the build-up of plaque (a process called atherosclerosis). The result is a lack of blood supply to the intestines. The disease can come on suddenly with severe abdominal pain or may develop over time. Treatment can include lifestyle changes, minimally invasive endovascular options, and surgery.
Superficial thrombophlebitis is a form of venous disease (disease of the veins) that occurs when a blood clot forms that partially or totally blocks blood flow in a vein in the superficial venous system. When this occurs in the deep venous system, it is called deep vein thrombosis or DVT, which is more serious because of the risk of a piece of clot breaking loose and traveling to the lungs (called pulmonary embolus, or PE). This can impair breathing and can even cause death.
A thoracic aortic aneurysm is an enlargement in the upper part of the aorta, the major blood vessel that routes blood to the body. Thoracic aortic aneurysms can cause aortic dissection (splitting of the aortic wall) and aortic rupture, leading to life-threatening internal bleeding. Thoracic aortic aneurysms, even those that are large, frequently do not cause symptoms. Some individuals, however, may experience symptoms such as: pain in the chest area; back pain; coughing or hoarseness; and difficulty breathing.
Thoracic endovascular aortic repair (TEVAR) is a minimally invasive option to conventional open surgery for patients suffering from thoracic aortic aneurysms (TAAs) who are not optimal candidates for traditional open repair. TEVAR can shorten hospital stays and reduce recovery periods. The University of Michigan Frankel Cardiovascular Center’s surgical team has more than two decades of experience performing TEVAR procedures and provides comprehensive care to patients with thoracic aortic aneurysms as well as to all aortic patients, including those who are high-risk.
All the blood vessels that run through your body make up your vascular system, which includes your arteries and veins. The Vascular Medicine Program, part of the Cardiovascular Center at the University of Michigan, offers a multidisciplinary approach to the diagnosis, treatment, follow-up and management of patients with all forms of vascular disease.
The vascular surgeons at the University of Michigan Cardiovascular Center work together every day to provide our patients with the most exceptional care and treatment possible for diseases of the circulatory system.
Venous disease is the impairment of blood flowing to the heart and is a common condition affecting men and women of all ages and activity levels. While many cases of venous disease are genetic, they can also be caused by environmental risks, pregnancy and other factors. Venous disease can range from cosmetic concerns to life-threatening conditions, including spider veins, varicose veins, deep vein thrombosis (DVT), and swollen or painful legs due to chronic venous insufficiency.
Treatment options for venous or vein disease vary depending on the diagnosis. They can range from medical therapies and compression stockings to surgical correction. Michigan Medicine venous health experts offer a full complement of endovenous (within the vein) and surgical treatments.
