Aneurysms are abnormal expansion of arteries caused by a weakness of the arterial wall. Common reasons are arterial hypertension, atherosclerosis, infection, trauma and hereditary or acquired connective tissue diseases. Aneurysms are usually asymptomatic, but can cause pain and ischemia, thromboembolism, spontaneous dissection and rupture, which can be fatal. The diagnosis is made by imaging methods (eg. As ultrasound, CT angiography, MR angiography, aortography). The treatment nichtrupturierter aneurysms by the modification of risk factors (z. B. strict control of blood pressure) plus imaging monitoring, or by open or endovascular insertion of a stent graft, depending on the size and location of the aneurysm and the presence of symptoms. The treatment of ruptured aneurysms is the immediate surgery, either by the insertion of a synthetic graft in an open operation or the insertion of endovascular stent grafts.

Aneurysms are as defined ? 50% increase in arterial diameter compared to the normal segment which results in localized weakness of the arterial wall. True aneurysms involve all three layers of the wall of the artery (intima, media and adventitia). A pseudoaneurysm (false aneurysm) is a connection between the arterial lumen and the overlying connective tissue, which is caused by a of artery; a blood-filled cavity originating outside the vessel wall and sealed the leak when they thrombosed. are aneurysms as divided fusiform (spindle-shaped enlargement of the artery) or saccular (localized aneurysm of the artery wall). Thrombi in the wall layers develop (laminated thrombi) the wall of each type can seam, are an indication that the blood flow is normal or almost normal behind the aneurysm.

Aneurysms can occur in any artery. Abdominal (abdominal aortic aneurysms (AAA)) and thoracic (thoracic aortic aneurysm) aortic aneurysms are most common and most important; Aneurysms of the major aortic branches (the subclavian artery and the Aa. Splanchnicae- aneurysms of the side branches of the aorta) are less frequent. Aneurysms of the peripheral arteries (peripheral artery aneurysms) and the cerebrovascular system (vascular lesions in the brain) are discussed elsewhere.
