What is an aortic aneurysm?
Is a limited expansion of the vessel partition of the aorta? The expansion is at least twice as wide as the nearest normal part of the vein. In practice, this means an extension of the main artery of more than three cm. Aneurysms can be shaped or coil-shaped bag.
The figures for incidence are uncertain. The incidence seems to increase, and it is probably hidden because of sudden death as a result of non-diagnosed aneurysms that burst in autopsy material available in bukdelen aneurysm of the aorta at 2-4% by the age of 50-60 years. The condition is four times as common in men than women.
What causes aortic aneurysms?
Atherosclerosis, which weakens the vessel wall, is the main cause. Risk factors for aneurysm is another blood disease, high blood pressure and smoking, family history of aneurysms of the aorta bukdelen; injury, inflammation, syphilis and connective tissue diseases are rare predisposing factors.
How aortic aneurysm diagnosed?
All aneurysms are typically symptom-free - unless they expand rapidly, or if they burst. Symptoms can sometimes arise from pressure on the surrounding structures: the abdominal aorta can cause spinal and intestinal pain, usually persistent. Chest section of the aorta can cause chest pain or symptoms caused by pressure on the esophagus, voiced cord nerve or the body's major samleare. There may be coughing blood as a result of compression of the trachea or bronchi (small airways) or hoarseness due to pressure on the left part of the vocal cord nerve.
Aneurysms in the groin and hamstrings can sometimes be known by the doctor. Aneurysm of the aorta can be detected as a random pulsating tumor in the abdomen. Fast-growing aneurysms can cause soreness in the stomach. Aneurysm of the thoracic portion of the aorta is most often incidental to findings on a radiograph of the chest.
Examination by ultrasound can show the size and extent of the aneurysm. In particular, aneurysms of the aorta appear well on ultrasound. The survey is used to control for monitoring any growth. CT (X-Drum) provides accurate measurements and shows the anatomy well, and is a significant alternative to ultrasound. It may also be relevant to X-ray examination with contrast of the aorta before any operation.
How are long-term prospects of aortic aneurysm?
An aortic aneurysm may be asymptomatic for life. Large aneurysms that expand, will eventually cause symptoms such as pain in the back / upper abdomen or symptoms caused by compression of the body hovedsamleare, esophagus or trachea. If the expansion continues, this will cause the aneurysm burst and sudden death.
Long-term outlook will depend on the aneurysm size and localization. Aneurysms of the aorta that is less than 5 cm, have little chance of rupture. Aneurysms are more than 7 cm, 3 of four cases of rupture within five years if one is not operated. An aneurysm operated gives life expectancy as the general population, provided that you do not have a concurrent cardiac disease.
A complication of an aneurysm is life-threatening bleeding, failure of blood supply to heart muscle, stroke, kidney failure and lack of blood supply to the bowel. Other complications include blood clots, infection of Vascular arrbrokk and Vascular leakage.
