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

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.
