Prognosis of Loeys-dietz Syndrome Prognosis of the condition can be dependent on the severity of the patient’s state. The condition is said to have a poor prognosis once aortic aneurysms are noted along with other arterial aneurysms. [syndromespedia.com]

In contrast to Loeys-Dietz syndrome, in other inherited syndromes associated with aortic aneurysms, surgery carries a poorer prognosis, and the aneurysms can be managed with medications for a longer period of time before surgery becomes necessary. [medicinenet.com]

The differential diagnosis between these connective tissue diseases is important because the progression and prognosis of aortic and branch vessel disease is significantly different. [e-sciencecentral.org]

Prevention Prevention of the said disease can be hard to attain as the condition is genetic. The only prevention measure that one can perform is to avoid rupture of the aortic aneurysm. [syndromespedia.com]

There’s no cure for the disorder, so treatment is aimed at preventing and treating symptoms. Due to the high risk of rupture, someone with this condition should be followed closely to monitor the formation of aneurysms and other complications. [healthline.com]

If an increased heart rate is present, atenolol is sometimes prescribed to reduce the heart rate to prevent any extra pressure on the tissue of the aorta. [en.wikipedia.org]
