[Surgery of aortic valve stenosis with porcelain aorta under hypothermic circulatory arrest].
This is a case report of a 52 year-old male patient with severe calcific aortic valve stenosis, associated with extended circular calcification of the ascending aorta and the aortic arch. Six months ago the patient underwent an explorative sternotomy in another institute, but the aortic valve replacement was not performed regarding the great risk of the porcelain aorta. The patient's complaints became more severe, so the authors recommended the excision both of the stenotic aortic valve and the calcified ascending aorta and replacement with a mechanical valve and vascular prosthesis. The operation was performed in deep hypothermia and total circulatory arrest with help of cardiopulmonary bypass. The calcified ascending aorta was excised without crossclamping. The vascular graft used for replacement of the ascending aorta was anastomosed to the proximal part of the aortic arch, then it was clamped and the extracorporal circulation was started again with rewarming of the patient. The aortic valve was replaced with a 21 mm St. Jude HP mechanical valve prosthesis in the usual manner. At last, the graft was anastomosed supracoronary to the proximal stump of the ascending aorta. Extracorporal circulation was discontinued without any difficulties. Apart from a few days of somnolence, the patient's recovery was uneventful, he was discharged from hospital on the 12th postoperative day. Three months after the surgery he had no complaints and returned to work without any problems.
