  "overview": [
    "An aortic aneurysm is a localized, permanent dilation of the aorta to at least one and a half times its normal diameter, most commonly caused by atherosclerosis weakening the vessel wall, though hypertension, connective tissue disorders such as Marfan syndrome, infection and trauma also contribute. Aneurysms occur in the abdominal aorta more often than the thoracic aorta and typically develop slowly and silently over years.",
    "The central danger is rupture: as the wall stretches and thins under arterial pressure, tension increases according to LaPlace's law, and once a critical diameter is reached the risk of catastrophic rupture rises sharply. Rupture causes massive internal hemorrhage and is a true surgical emergency with high mortality even when treated immediately, which is why size-based surveillance and elective repair before rupture are central to management.",
    "Nursing care spans two very different phases: the largely asymptomatic surveillance period, where blood pressure control and monitoring for expansion are key, and the emergency phase if dissection or rupture occurs, where recognizing sudden severe pain and hemodynamic collapse and mobilizing rapid surgical intervention are lifesaving. Postoperative care after elective or emergent repair focuses on monitoring for bleeding, organ perfusion and graft complications."
