In patients with so-called porcelain
aorta characterized by calcification of the total aorta, manipulation
of the ascending aorta can cause cerebral infarction and other
conditions due to aortic dissection or rupture and calcified
debris. In the present case with ischemic cardiomyopathy and
porcelain aorta, an occlusion balloon catheter was inserted into
the ascending aorta to avoid its clamping, followed by Dor operation
and CABG under cardiac arrest with normothermic extracorporeal
circulation. Techniques such as deep hypothermic circulatory
arrest and surgery while the heart is beating are often currently
used as auxiliary methods to avoid aortic clamp. However, the
present case with insufficient left ventricular function required
a left ventriculotomy, and thus the technique presented here
is useful for shortening the surgical time and ensuring a reliable
outcome of the operation.
