The correct answer is D.) aortic aneurysm dissection
Aortic aneurysm dissection is an intramural tear of the aorta instigated by a dilation, or aneurysm, of the aorta. Aortic aneurysm dissection is a life-threatening emergency. Tears often occur in the intimal layer of the aorta, with blood collecting into the medial layer. Back pain is the common presenting symptom. Syncope and hypotension occur less frequently. Aortic dissections most often occur in older males. Most aortic aneurysms are asymptomatic before rupture or dissection. Etiology of the aortic aneurysm depends on its location. Ascending aortic aneurysms are primarily caused by medial degeneration in diseases such as Marfan syndrome. Descending aortic aneurysms are primarily caused by atherosclerosis.
Beta blockers are the primary medical treatment. Surgical intervention is indicated for many types of aortic dissection. Even with appropriate treatment, mortality from aortic aneurysm dissection is very high.
