动脉粥样硬化形成腹主动脉廇

动脉粥样硬化形成腹主动脉廇

动脉粥样硬化处的动脉壁变得很薄弱,容易膨出形成动脉廇。图示:肾动脉以下的腹主动脉廇。大动脉廇的直径大于6到7cm时很容易引起破裂。

Atherosclerosis may weaken the wall of the aorta such that it bulges out to form an aneurysm. An atherosclerotic aortic aneurysm typically occurs in the abdominal portion below the renal arteries, as shown here. Aortic aneurysms that get bigger than 6 or 7 cm are likely to rupture.
