Objective To explore the operational indications, preoperative evaluation,operative essentials and clinical prospect of endovascular repair(EVR) for aortic dissection.Methods Twenty-six patients underwent EVR for aortic dissection and all cases were Stanford B dissection.Four patients had two or more tear entries in different sites.Computed tomography angiography(CTA) or digital subtraction angiography(DSA) were used as preoperative evaluation methods.Results The grafts were installed successfully in 26 patients(100%).The patients were followed up for 1 to 18 months after treatment,and there was no endoleaks and organ or limb ischemia in all the patients.Conclusion Endovascular repair was simple,safe and effective in treating aortic dissection and dissecting aneurysm.

Objective To discuss related factors of perioperative pulmonary complications in infants with congenital heart disease and provide a scientific basis to improve the quality of intensive care in in-fants with congenital heart disease after surgery. Methods Tracking survey was carried out in 225 cases of infants with congenital heart disease in our city to observe the perioperative lung condition from March 2005 to May 2007. Every process that might occur pulmonary complications,such as preoperative care of children,anesthesia and cardiopulmonary bypass surgery (CPB) management and postoperative monitoring was closely observed. Statistical analysis was conducted according to emerging problems and summarized the relevant factors and nursing methods. Results 225 infant patients passed the operation with no seri-ous complications.Conclusions Effective treatment and nursing during every process of perioperation was the key factor to reduce pulmonary complications.

ObjectiveTo investigate the incidence of skeletal and/or articular malformations in central core disease (CCD) patients, and their risk of malignant hyperthermia (MH) in orthopedics. Methods28 unrelated patients with central core disease collected in the past 23 years were analyzed retrospectively. Results22 patients showed limb muscle weakness, while 6 patients didn't show any clinical symptom. Skeletal and/or articular malformations appeared in 21 patients, including joint contracture in 11, joint dislocation in 9, scoliosis in 12, lordosis in 5 and thoracic deformity in 1. 6 of the 10 patients could not endure orthopedic operation because of MH attack or dubitable MH attack. Calcium-induced calcium release (CICR) test performed on other 8 patients with MH family history or MH attack showed all those patients were MH susceptibilities. ConclusionSkeletal and/or articular malformations are common in CCD, as well as MH attack in orthopedics.
