Emergency operation on the dissected ascending aorta of an adolescent with aortic coarctation.

摘要

This case report describes the successful repair of an acute dissection of the ascending aorta in a 16-year-old girl. The dissection appeared to be related to the presence of an aortic coarctation. Furthermore, a bicuspid aortic valve was found. Echocardiography was helpful for quick pre-operative diagnosis. A computed tomography (CT) scan was used post-operatively to confirm these results. At the onset of extracorporeal circulation, active drainage was applied at the femoral vein by means of a routinely built-in shunt bypassing the venous reservoir. The practical implementation of this shunt is described in this report. One femoral artery and one femoral vein were cannulated, resulting in a blood flow index of 2.21.min(-l).m(-2) which proved to be sufficient for blood supply to both the lower and the upper parts of the body. Successful percutaneous dilatation of the coarctation was performed five months after the first operation.
