Three patients with rupture of thoracic aortic aneurysm into the lung with formation of pseudoaneurysm were admitted to our hospital in 1991, of whom, 2 had ascending aortic aneurysms which ruptured into the right upper pulmonary lobe, and another one had descending aortic aneurysm rupturing into the left upper lobe. All 3 cases were misdiagnosed as having pulmonary carcinoma or mediastinal tumor by the other hospital as well as by us. Correct diagnosis was made by aortography or at exploratory thoracotomy. Our preliminary experiences in the diagnosis and treatment of the disease are presented in this paper.

A technique of sutureless trachea anastomosis in rabbits using carbon dioxide laser was reported herein. In 6 rabbits with laser-assisted trachea anastomoses, only one was found to have slight anastomotic stenosis after operation, whereas 6 rabbits with conventional sutures all were found to have anastomotic stenosis. Results show that laser-assisted trachea anastomosis has certain advantages over the conventional suturing technique, thereby finding wide application in clinical tracheal reconstruction and lung transplantation.

A report on the results of surgical treatment of 5 cases of DCRV and its associated anomaly was presented in this paper. No definite diagnosis of DCRV was made prior to operation. It was found that 2 cases had DCRV as an isolated anomaly, another 2 had the disease associated with VSD, and the remaining 1 had DCRV with right ventricle to left atrium cannulation. Muscular membrane septum type was found in 3 cases, and muscular bundle type in 2.4 cases diagnosed as having DCRV or DCRV with other heart anomalies during operation were treated properly and discharged fully recovered. 1 case died of acute heart insufficiency. Pathologic anatomy and physiology, associated anomalies of DCRV, and some experience with the operative approach were discussed in this article.

This paper reports 30 cases of myasthenia gravis (MG) treated by thymectomy from 1965 to 1990 in our hospital. Of all the 30 cases of MG, peripheral blood lymphocyte subpopulation was determined in 10, and anti-acetylcholine receptor antibody titer in 6, before and after operation. The results demonstrated the efficacy of thymectomy against MG. We considered that with application of hormone before and after operation to regulate immune function of the body, and/or with plasma exchange to remiss symptoms, all the patients with generalized MG may be indicated for treatment by thymectomy. Indication of treatment does not depend on age, sex and the course of the disease. But radical operation, proper anesthesia and appropriate use of antibiotics may ensure safety of the operation and its curative effect.
