Objectives: After studying the article entitled “Detection of Aortic Dissection by a Combined Abdominal Sonogram and Computed Tomography Angiogram: A Case Study,” you will be able to:
Describe the types of aortic dissection
Describe the sonographic features of an aortic dissection
Identify associated underlying diseases that may lead to an aortic dissection
Sonographic appearance of an acute aortic dissection typically includes Extrinsic compression of the aortic bifurcation Gray-scale filling of the aortic lumen Aneurysmal dilation of the iliac arteries A linear echogenic signal within the lumen
In the Stanford and DeBakey systems of aortic dissection classification, the types that are the same are DeBakey Type I and Stanford B DeBakey Type II and Stanford B DeBakey Type III and Stanford B DeBakey Type III and Stanford A
An arterial dissection is the result of a disruption between the Tunica intima and adventitia Tunica intima and tunica media Tunica media and adventitia Tunica media and the smooth muscle cell layer
The types of aortic dissections considered most dangerous are DeBakey Type I and Type II DeBakey Type I and Type III DeBakey Type II and Type III DeBakey Type III and Stanford A
In the case reported, the aortic dissection was classified as a DeBakey Type I DeBakey Type II Stanford A Stanford B
An underlying disease frequently associated with aortic aneurysms is Eagle syndrome Tunica syndrome Marfan syndrome Diabetes
Aortic dissections most commonly treated medically include DeBakey Type I and Stanford A DeBakey Type II and Stanford A DeBakey Type III and Stanford A DeBakey Type III and Stanford B
Color Doppler imaging of an aortic dissection is likely to show Two lumens, each with different hemodynamic characteristics Two lumens, each with the same hemodynamic characteristics A single lumen with uniform, laminar flow hemodynamics A single lumen with disturbed, turbulent flow hemodynamics
A very common symptom of an acute descending aortic dissection, and one reported in the case presented, is Visual loss Chest/back pain Headache Heart failure
Mortality secondary to aortic dissection is highest in Women age > 65 years with a smoking history Women age > 65 years with a history of hypertension Men age > 65 years with a smoking history Men age > 65 years with a history of diabetes
