Description:
This procedure is used to treat aneurysms of the descending
aorta within the thorax. Weakening of the wall of the
aorta, due to atheroma, high blood pressure, or, less
commonly, infection, can lead to an aneurysm. Aneurysms may
rupture, causing internal bleeding.
Aneurysms of the thoracic aorta are potentially serious.
Untreated, five year survival is 10 to 15%. Ruptured
thoracic aneurysm is almost always fatal, even with treatment.
Aneurysms of the thoracic aorta are relatively uncommon.
Conventional surgery involves replacing the affected part of
the aorta with a graft. The operation usually takes several
hours and postoperative recovery can be prolonged.
Stenting involves placing a tube inside the aorta under
X-ray control. Specialized catheters and wires are used to
introduce the stent, most commonly through the femoral artery.
