Diagnosis With Brief Discussion
- Diagnosis
- RVOT pseudoaneurysm
- Radiologic Findings
- There is a round mass like lesion with calcified rim in the mediastinum on chest CT scan. The lesion is inside the pericardium (Fig 3,4). On operative findings, traumatic pseudoaneurysm was confirmed and the origin was right ventricular outflow tract.
- Brief Review
- A pseudoaneurysm, also known as a false aneurysm, is a hematoma that forms as the result of a leaking hole in an artery. Note that the hematoma forms outside the arterial wall, so it is contained by the surrounding tissues. Also it must continue to communicate with the artery to be considered a pseudoaneurysm.
Pseudoaneurysm of the right ventricular outflow tract (RVOT) is a rare complication of cardiac surgical procedures done for congenital heart disease. In the literature, the initial procedures included right ventriculotomy and placement of an outflow patch, conduit, or homograft. The treatment should be carried out soon after diagnosis because of the risk of spontaneous rupture.
