[Pseudoaneurysm in the vicinity of the ascending aorta caused by contained disruption at the insertion site of a coronary artery bypass graft. A case report].
In this case report a 65-year-old patient came into the emergency ward with acute chest pain after coronary artery bypass graft operation in 1985. On routine chest X-ray in 1995 a mediastinal widening was diagnosed. The chest X-ray in 1997 (Figure 1) showed an increase of the diameter of the known mediastinal widening. Therefore a CT-scan was performed (Figures 2a and 2b). This showed an enhancement of contrast material in a contained structure, without identifying its origin. Therefore a coronary angiography was done. Here, we diagnosed a contained disruption of the aorta at the insertion site of the bypass graft at the right coronary artery. Figure 3a shows leakage of contrast material out of the aorta into the pseudoaneurysm and in Figure 3b this is demonstrated in a schematic drawing. Figure 4a shows supraselective imaging of the pseudoaneurysm, demonstrated in a schematic drawing in Figure 4b. As the chest pain could only be handled by i.v.-medication, betablocker and bed rest we decided to operate. Intra-operatively the diagnosis was confirmed (Figure 5a and 5b). Postoperatively the patient died due to cerebral ischemia. Despite the lethal outcome an operative revision appears even retrospectively justified because of the increasing size of the pseudoaneurysm in addition to new symptoms that were difficult to treat. On the other hand there are no data available in order to estimate the risk of a spontaneous course.
