Question:

Which of the following answer choices are correct?
1. Chest X-ray is useful in determining the timing of operation in asymptomatic patients with aortic aneurysm
2. Computed tomography is useful in determining the timing of operation in asymptomatic patients with aortic aneurysm
3. Computed tomography is useful for the diagnosis of acute thoracic aortic dissection
4. Chest X-ray is necessary for the diagnosis of acute thoracic aortic dissection
5. Chest X-ray is necessary for the postoperative evaluation of patients.





Answer:

The correct answers for the question "Which of the following answer choices are correct?" are:

2. Computed tomography is useful in determining the timing of operation in asymptomatic patients with aortic aneurysm

3. Computed tomography is useful for the diagnosis of acute thoracic aortic dissection



Explanation

1. [Computed tomography is the most widely used noninvasive technique for the diagnosis of thoracic aortic disease, as it provides information about the location, size and extent of the disease. It is of particular value in diagnosing thoracic aortic dissection, in determining the timing of operation for asymptomatic patients and for postoperative evaluation].

2. [Computed tomography is the most widely used noninvasive technique for the diagnosis of thoracic aortic disease, as it provides information about the location, size and extent of the disease. It is of particular value in diagnosing thoracic aortic dissection, in determining the timing of operation for asymptomatic patients and for postoperative evaluation].

3. [Computed tomography is the most widely used noninvasive technique for the diagnosis of thoracic aortic disease, as it provides information about the location, size and extent of the disease. It is of particular value in diagnosing thoracic aortic dissection, in determining the timing of operation for asymptomatic patients and for postoperative evaluation].

4. [Findings on the chest radiograph may be diagnostic of a thoracic aortic aneurysm. However, approximately 17% of the patients with documented aortic aneurysms or dissections have no abnormalities on chest radiography].

5. [Computed tomography is the most widely used noninvasive technique for the diagnosis of thoracic aortic disease, as it provides information about the location, size and extent of the disease. It is of particular value in diagnosing thoracic aortic dissection, in determining the timing of operation for asymptomatic patients and for postoperative evaluation].

Abstract
Aortic aneurysms are a rare cause of consumption coagulopathy. We describe an 82-year old woman with a previously unrecognized giant aneurysm of the thoracic aorta. The first manifestation of this condition was hemoptysis that was due to an exacerbation of chronic disseminated intravascular coagulation. The patient eventually died despite intensive conservative treatment, as she declined late surgical intervention. This case underscores the need to exclude aortic aneurysms by performing a chest X-ray in elderly patients with bleeding disorders.
