Aneurysm, by definition, is the name given to the regional enlargement and ballooning of the vessels in the body. To define it medically, an aneurysm is any artery in the body that is regionally wider than 1.5 times its normal diameter. The most common site of aneurysm in the body is the abdominal main artery, the abdominal aorta. Although the normal diameter varies according to the weight, height and body characteristics of the person, abdominal aortic aneurysm is mentioned when the diameter of the aorta, which is usually 2-3 cm, becomes larger than 4 cm.
Hypertension and cholesterol are among the most important causes of abdominal aortic aneurysm, which generally shows familial and genetic inheritance. However, the risk of developing abdominal aortic aneurysm increases in some connective tissue diseases such as Marfan Syndrome. It is an insidious disease that generally progresses silently. The most common complaint is abdominal pain. Apart from this, it can also progress with complaints that can be seen in gastrointestinal system diseases such as diarrhea, constipation attacks, indigestion and bloating. In some of the patients, it is possible to feel a pulse in the abdomen. However, the most important thing to know about abdominal aortic aneurysm is that it can progress for a long time without complaints until the advanced stages of the disease. Since the risk of spontaneous rupture and bursting is high, especially in aneurysms with a diameter greater than 5 cm, and the risk of death of the patients in this case is approximately 50%, people with risk factors should not be vigilant in terms of abdominal aortic aneurysm.
The diagnosis of the disease is often made in the order of examinations such as ultrasonography and tomography performed for other reasons. Medicated tomography for imaging the abdominal vessels is absolutely necessary in order to choose the definitive diagnosis and appropriate treatment method.
5 cm. Aneurysms smaller than the diameter should be followed up at intervals such as 6 months or 1 year. In patients with a diameter greater than 5.5 cm, with an increase in diameter of more than 0.5 cm in 6 months, or with a diameter of 4.5-5.5 cm and whose pain complaints continue despite all kinds of medical treatment, surgical or endovascular (closed by angiography method) transactions) are required.
Endovascular procedures are a treatment method performed in the angiography room and applied only through 5 cm incisions in the groin.
After evaluating the anatomical features of the abdominal aorta in 3D with computed tomography, individual and special stent grafts are prepared for each patient. In the angiography room, first of all, both inguinal veins are surgically prepared, and stent grafts specially prepared for the patient are placed into the vein to close the aneurysmatic vascular areas with the procedure performed through these veins. Then, the vein in the groin area is repaired, the incisions are closed and the process is terminated.
