Stanford Type A Acute Aortic Dissection with Myasthenia Gravis：Report of a Case

はじめに　重症筋無力症（MG）を合併した低体温循環停止下の手術症例はまれである．われわれは，MGを合併したStanford A型急性大動脈解離（A型AAD）の手術症例を経験したので，若干の文献的考察を加えて報告する．

The patient was a 76-year-old man with myasthenia gravis （MG）. He suffered from a sudden back pain, and was diagnosed with Stanford type A acute aortic dissection. We performed emergency graft replacement of the ascending aorta under cardiopulmonary bypass with hypothermic circulatory arrest. A neuromuscular blocking agent was administered only once at tracheal intubation. The operation was completed without incident. A neuromuscular antagonist was administered once just after the operation. Fifteen hours after the operation, the tracheal tube was extubated. His postoperative course was uneventful and he has been well for three years since the operation. This is a very rare surgical case report of acute aortic dissection with MG.
