The 52-year-old Ms. Zhang how did not expect, her eyelids droopy, riding a bike on the street road also did not see a close call; more to her surprise is that the original vision problem is not a problem at all, the culprit is actually thymoma. Ms. Zhang told reporters that in the past half a month, I do not know what happened, she often feel weakness in the limbs, eyes open. Once riding an electric bike on the street, suddenly a black eye, almost hit a person. She thought it was a vision problem, went to the ophthalmology clinic, and then was referred to the thoracic surgery. Zhang Jijun, director of thoracic surgery at the Fourth Hospital, quickly diagnosed her with thymoma combined with myasthenia gravis. It is understood that for patients with myasthenia gravis, preoperative dose adjustment is quite important, and there is a narrow line between insufficient drugs and drug overdose, which, if not careful, can lead to tragic postoperative respiratory failure and even death. The hospital’s thoracic surgery department, neurology and anesthesiology department cooperated with each other and performed a median sternal split, thymectomy and cleansing of anterior mediastinal fatty tissue for Ms. Zhang, who resumed autonomous breathing at the end of the operation. During the operation, it was found that in addition to multiple tumors on the thymus, Ms. Zhang also had multiple tiny thymomas in the cleared adipose tissue. Outside the ward, the reporter saw Ms. Zhang, who was walking a week after the operation. She looked good, sitting and communicating with the reporter, her eyes were open all the time, compared to before the operation both eyes were drooping downward has improved a lot. Dr. Zhang Jijun, who has been researching myasthenia gravis since the early 1990s, said that myasthenia gravis can be combined with many other autoimmune diseases, including hyperthyroidism, rheumatoid arthritis, and simple red blood cell aplastic anemia. These can often blind the patient and lead to misdiagnosis, sometimes even by non-specialist medical personnel. Moreover, myasthenia gravis is closely related to the thymus gland, and all such patients will have thymic hyperplasia or thymoma or thymic atrophy, thus, solving the thymus problem is the root.
