A persistent false channel in chronic aortic dissection does not predispose to late aneursym formation.
Annulo-aortic ectasia is not associated with aortic valvular incompetence.
Atherosclerosis causes about 25% of all thoracic aneurysms.
Ascending aortic aneurysms and thoracoabdominal aneurysms occur with roughly equal frequency.
Hoarseness is a clinical sign of aortic arch aneurysm.
Question 2: Which of the following statements is true?
Petechiae and ecchymosis from disseminated intravascular coagulation are a contraindication to surgery for thoracic aneurysms.
Aortography accurately defines the intraluminal diameter of descending aortic aneurysms.
The mean interval to rupture after the development of symptoms is one year.
Anastomoses should only be made to the outer wall of an aneurysm originating from the false channel of a chronic dissection.
The aneurysm walls are not closed over the graft in repair of a thoracoabdominal aneurysm.
Question 3: Which of the following statements is true regarding operative intervention?
A generous length (over 5 cm) of graft should be left as an "elephant trunk" to facilitate second stage repair.
Repair of a thoracoabdominal aneurysm carries a higher early operative mortality than ascending or descending thoracic aneurysms.
Marfan patients have poorer survival after repair of ascending aortic aneurysms.
Rupture of new aneurysms and heart failure are important modes of early death after operation.
Question 4: Which of the following statements is true for postoperative followup?
Renal failure is a common complication after repair of descending and thoracoabdominal aneurysms.
Retrograde cerebral perfusion has been shown to be superior to hypothermic circulatory arrest for cerebral protection during aneurysm repair.
Marfan syndrome is a risk factor for reoperation and recurrent aneurysm.
Chronic renal failure is not an independent preoperative risk factor for early or late death following aneurysm repair.
