In patients with aortic dissection, what event can fluid overload lead to?

In patients with aortic dissection, fluid overload can cause increased risk of rupture. This condition involves a tear in the inner layer of the aorta, which can lead to blood flowing between the layers of the aortic wall. When excessive fluid is administered, it can raise blood pressure and increase the volume of blood flowing through the aorta. This heightened pressure places additional stress on the already compromised vessel wall.

As the dissection progresses, the aorta's structural integrity can be further jeopardized, making it more prone to rupture. The critical nature of the aorta in maintaining systemic circulation means that even slight increases in pressure can lead to catastrophic outcomes, including rupture, which can result in significant morbidity and mortality for the patient. Thus, fluid management is crucial in these patients to minimize the risks associated with their condition.
