What are the complications with an abdominal aortic aneurysm?
Rupture is a feared problem. Rupture of an abdominal aneurysm is a
catastrophe. It is highly lethal and is usually preceded by excruciating pain in
the lower abdomen and back, with tenderness of the aneurysm. Rupture of an
abdominal aneurysm causes profuse bleeding and leads to shock. Death may rapidly
follow. Half of all persons with untreated abdominal aortic aneurysms die of
rupture within five years. Abdominal aortic aneurysms are the 13th leading cause of
death in the U.S.
Peripheral embolization of clot within the aneurysm can occur when a piece of
clot comes loose and travels further out in the arterial system. This clot
fragment can lodge in a smaller artery and block the flow of blood. Infection of
aneurysms can occur from turbulent blood flow from the rough inner surface of
the affected aorta.
How are abdominal aortic aneurysms repaired?
The goal of surgical treatment of abdominal aortic aneurysm is to prevent aneurysm rupture. Traditionally, repair of aortic aneurysms has been surgical. The operation consists of opening the abdomen, finding the aorta and removing (excising) the aneurysm. A synthetic Dacron tube that replaces the removed piece of aorta is sewn into place.
A less invasive procedure for aortic aneurysm is endovascular surgery. This minimally invasive procedure that allows the grafts
(stent) to be guided within the blood vessel itself to the site of the aneurysm without the need to cut open the abdomen. Not all aneurysms can be fixed in this manner and there may not be a long-term benefit to this type of surgery. Though the post-operative course is shorter, there is a need for closer follow-up and testing.
Abdominal pain is pain in the belly and can be acute or chronic. Causes include inflammation, distention of an organ, and loss of the blood supply to an organ. Abdominal pain can reflect a major problem with one of the organs in the abdomen such as the appendix, gallbladder, large and small intestine, pancreas, liver, colon, duodenum, and spleen.
Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, or even fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
High blood pressure, also known as hypertension, is a repeatedly
elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above
140 with a diastolic pressure above 90. There are two causes of high blood pressure, primary and secondary. Primary high blood pressure is much more common that secondary and its basic causes or underlying defects are not always known. It is known that a diet high in salt increases the risk for high blood pressure, as well as high cholesterol. Genetic factors are also a primary cause. Secondary high blood pressure is generally caused by another condition such as renal hypertension, tumors, and other conditions. Treatment for high blood pressure is generally lifestyle changes and if necessary, diet.
Diabetes mellitus is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Sexually transmitted diseases, or STDs,
are infections that are transmitted during any type of sexual exposure,
including intercourse (vaginal or anal), oral sex, and the sharing of sexual
devices, such as vibrators. Women can contract all of the STDs, but may have no symptoms, or have different symptoms than men do.
Cholesterol is naturally produced by the body, and is a building block for cell membranes and hormones. Low-density lipoprotein (LDL) cholesterol is the "bad" cholesterol, conversely, high-density lipoprotein (HDL) cholesterol is the "good" cholesterol. High cholesterol treatment includes lifestyle changes (diet and exercise), and medications such as statins, bile acid resins, and fibric acid derivatives.
Sexually transmitted diseases, or STDs, are infections that are transmitted during any
type of sexual exposure, including intercourse (vaginal or anal), oral sex, and
the sharing of sexual devices, such as vibrators. Although treatment exists for many STDs, others currently are
usually incurable, such as those caused by HIV, HPV, hepatitis B and C, and HHV-8.
Marfan syndrome is hereditary condition affecting connective tissue. A person with Marfan syndrome may exhibit the following symptoms and characteristics: dislocation of one or both lenses of the eye; a protruding or indented breastbone; scoliosis; flat feet; aortic dilatation; dural ectasia; stretch marks; hernia; and lung collapse. Though there is no cure for Marfan syndrome, there are treatments that can minimize and sometimes prevent some complications.
Drug addiction is a chronic disease that causes drug-seeking behavior and drug use despite negative consequences to the user and those around him. Though the initial decision to use drugs is voluntary, changes in the brain caused by repeated drug abuse can affect a person's self-control and ability to make the right decisions and increase the urge to take drugs. Drug abuse and addiction are preventable.
Smoking is an addiction. More than 430,000 deaths occur each year in the U.S. from smoking related illnesses. Secondhand smoke or "passive smoke" also harm family members, coworkers, and others around smokers. There are a number of techniques available to assist people who want to quit smoking.
A heart murmur is the sound generated when blood flow within the heart is not smooth. Causes of heart murmurs can be functional, congenital, or caused heart valve conditions. Symptoms of a heart murmur may be none, or may include chest pain, shortness of breath, and arm, leg, and ankle swelling. Treatment of a heart murmur depends on the cause.
Ehlers-Danlos syndromes are genetic disorders that include symptoms such as loose joints, tissue weakness, easy bruising, and skin that stretches easily. There are seven types of Ehlers-Danlos syndromes: Classical type, Hypermobility type, Vascular type, Kyphoscoliosis type, Arthrochalsia type, Dermatosparaxis type, and Tenascin-X Deficient type. Treatment for Ehlers-Danlos syndromes depends on which symptoms are present.
Syphilis, a sexually transmitted disease, is caused by a microscopic, wormlike bacterial organism called a spirochete. There are three stages of syphilis. The first involves the formation of the chancre. The second stage often includes hair loss, a sore throat, white patches in the nose, mouth, and vagina, fever, headaches, and a skin rash. The third stage can cause extensive damage to the internal organs and the brain, and can lead to death. Though early infection often resolves on its own, treatment usually varies based on the stage of the infection at the time of diagnosis.
Medical shock is a life-threatening medical condition. There are several types of medical shock, septic shock, anaphylactic shock, cardiogenic shock, hypovolemic shock, and neurogenic shock. Causes of shock include heart attack, heart failure, heavy bleeding (internal and external), infection, anaphylaxis, spinal cord injury, severe burns, chronic vomiting or diarrhea. Low blood pressure is the key sign of sock. Treatment is dependant upon the type of shock.
Relapsing polychondritis is an uncommon, chronic disorder of the cartilage that is characterized by recurrent episodes of inflammation of the cartilage of various tissues of the body. Tissues containing cartilage that can become inflamed include the ears, nose, joints, spine, and windpipe (trachea). Tissues that have a biochemical makeup similar to that of cartilage such as the eyes, heart, and blood vessels, can also be affected. Nonsteroidal antiinflammatory medications (NSAIDs) is used as treatment for mild cases of the disease. Steroid-related medications also are usually required.
Takayasu disease (also referred to as Takayasu arteritis) is a chronic inflammation of the aorta and it's branch arteries. Takayasu disease is most common of Women of Asian descent and usually begins between 10 and 30 years of age. Symptoms include: painful extremities, dizziness, headaches, chest and abdominal pain, and a low-grade fever. Treatment for Takayasu disease includes cortisone medication to suppress the inflammation.
Loeys-Dietz syndrome is a syndrome is an inherited genetic syndrome characterized by aortic aneurysms in children. Children with Loeys-Dietz syndrome are at a greater risk of dying from the aortic aneurysms, because the aneurysms are prone to rupture at a smaller size than other aneurysms. Physical characteristics of the syndrome include early fusion of the skull bones, widely spaced eyes, and split uvula or cleft palate. Treatment includes surgical repair fo the aneurysms.
Cholesterol occurs naturally in the body. High blood cholesterol levels increase a person's risk of developing heart disease, heart attacks, strokes, TIAs, and more. In addition to medication (fibrates, statins, bile acid sequestrants, and niacin), lifestyle changes can be made to lower blood cholesterol levels
