Surgery>>>>>Thoracic Aneurysms and Aortic Dissection
Question 5#

The following is NOT true regarding anastomotic pseudoaneurysms:

A. Can arise from deterioration of aortic tissue due to infection
B. Have increased in incidence with an influx of cardio-vascular surgery
C. Commonly occur in patients with Marfan syndrome
D. Are associated with high incidence of morbidity and rupture

Correct Answer is B

Comment:

Anastomotic pseudoaneurysms can be caused by technical problems or by deterioration of the native aortic tissue, graft material, or suture. Commonly, they occur in patients with Marfan syndrome. Tissue deterioration usually is related to either progressive degenerative disease or infection. Improvements in sutures, graft materials, and surgical techniques have decreased the incidence of thoracic aortic pseudoaneurysms. Should thoracic aortic pseudoaneurysms occur, they typically require expeditious surgical or other intervention because they are associated with a high incidence of morbidity and rupture.
