【Abstract】 Objective To summarize the authors’ clinical experience on the surgical treatment of critical type of myasthenia gravis (MG). Method A series of 38 patients with critical type of MG treated by thymectomy between 1990 and 1999 were reviewed. There were 14 males and 24 females with a mean age of (36.10±12.15) years. Fifteen patients developed crisis for twenty times before operation. Results Postoperatively, nineteen patients developed crisis by twenty times, no perioperative death occurred. All patients were discharged with improvement.Conclusion There was a trend toward crisis in the critical type of MG, timely tracheotomy with auxiliary ventilation is an effective and safe measure for the crisis. Unique preoperative preparation should not be overemphasized, and if there is coexiastent autoimmune disease, (mainly hyperthyroidism) operation is not contraindication.(Shanghai Med J, 2000,23∶ 14 15)更多还原
