Objective To investigate the clinical efficacy and significance of preoperative superselective endovascular embolization in treatment of patients with vascularized meningioma.Methods 3-9 days before operation, 98 patients with vascularized meningioma underwent DSA and preoperative superselective embilization with PVA particles, gelatin sponge, and silk. The surgical intervention was performed after embolization. Results The vascularized meningioma was mainly supplied by the middle meningeal artery, ascending pharyngeal artery, occipital artery, internal maxillary artery as well as submeningeal artery. After the supplying artery was embolized, tumors' staining in 42 cases disappeared completely and that of 56 cases disappeared totally or partly. Most patients were operated on 3-9 days after embolization. 64 tumors were removed completely, while other 34 cases were removed totally or partly. The average volume of bleeding during the operation was 950 ml in the former and 1 500 ml in the latter.Conclusions The best time for operation is 7～9 days after embolization. Preoperative embolization of the vascularized meningioma contributes to reduce the bleeding significantly during the operation, increase the safety of the operation and improve the total removal of the tumor. It is a safe and effective microinvasive method.

A blood film slide taken from a patient previously diagnosed as vivax malaria in Mojiang County, Yunnan Province, showing atypical forms. The ring forms had multinuclei, and the late trophozoites trended to form band. The schizonts and gametocytes were somewhat alike to Plasmodium vivax. PCR amplification confirmed that the patient was infected by P.knowlesi.

Objective To evaluate the clinical characteristics of aortic dissection in pregnant patients with Marfan syndrome and the maternal and fetal outcomes in cardiovascular surgery. Methods Seven pregnant women with Marfan syndrome with aortic dissection were identified, who were treated in Beijing Anzhen Hospital Affiliated to Capital Medical University between January 2012 and September 2014. Patient charts were reviewed for cardiovascular surgery, occurrence of complications, clinical features and the maternal and fetal outcomes. Results (1)Among 7 patients, 4 cases were diagnosed as type A aortic dissection and 3 were cases diagnosed as type B aortic dissection. The diagnosis mainly depends on CT angiography. New York Heart Association(NYHA)classify into 5 of levelⅡ, 1 of levelⅢ, 1 of leveIⅣ. Except for 1 patient with cardiac tamponade lead to heart failure, the remaining 6 cases had no complications.(2)Three patients underwent heart surgery with cardiopulmonary bypass in second trimester and two patients underwent heart surgery in third trimester. Two patients terminated pregnancy before heart surgery(one of whom underwent artificial abortion,one of whom underwent cesarean section in second trimester).(3)The methods of cardiovascular surgeries were as follow:3 of Bentall+Sun′, 1 of Bentall+Sun′+right coronary artery bypass grafting, 1 of Bentall, 1 of the whole chest aorta replacement surgery, and 1 of femoral artery catheter chest aorta with membrane mesh stent implantation. The diameter of aortic roots measured during operation were 5 cm in 2 cases, 7 cm in 2 cases and 10 cm in 2 cases respectively. Among the 7 cases, 3 were conducted cesarean sections during cardiovascular surgery,1 was terminated pregnancy due to intrauterine fetal death after cardiovascular surgery, and 1 was conducted cesarean section due to severe early-onset preeclampsia at 30 weeks of pregnancy after cardiovascular surgery. (4)Among the 7 cases, 3 were conducted cesarean sections during cardiovascular surgery, the order of which was implemented cesarean section under general anesthesia firstly and then operated cardiovascular surgery with cardiopulmonary bypass and heparinization. Two were conducted cardiovascular surgery after termination of pregnancy by early artificial abortion operation or hysterotomy. 1 was conducted Bentall surgery at 18 weeks of pregnancy, after that the patient was receiving warfarin until the fetal brain hemorrhage was examined by ultrasound at 31 weeks of pregnancy;the patient was conducted cesarean section due to intrauterine fetal death. 1 was conducted heart surgery at 24 weeks of pregnancy and continue the pregnancy to 30 weeks, was conducted cesarean section due to severe early-onset preeclampsia at 30 weeks of pregnancy.(5)Among 7 patients, three patients underwent heart surgery with cardiopulmonary bypass combined with cesarean section. Two patients terminated pregnancy after heart surgery. Two patients terminated pregnancy before heart surgery. Six patients were alive and one patient died of multiple organ failure.(6)3 cases of newborn with birth body mass between 1 080 to 1 490 g.1 case of birth died after 14 d. 2 cases for newborns were alive without exception. Conclusion Aortic dissection poses serious risk for pregnant women with Marfan syndrome and the fetus, and the mortality rates for both the mother and the fetus are high. Early diagnosis and appropriate treatment should be based on maternal and fetal conditions (such as aortic dissection, gestational age). When fetus is mature, cardiovascular surgery should be carried out with cesarean section. A multi-disciplinary team between obstetric and cardiovascular surgery is crucial to the outcome of these critical patients.

Objective To evaluated the role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of thoracic tuberculosis.Methods The study was retrospective,from September 2009 to September 2012,38 patients who underwent EBUS-TBNA were finally diagnosed of thoracic tuberculosis,with enlarged hilar or mediastinal Iymph nodes on chest enhanced computed tomography(≥ 1.0 cm).Patients in whom EBUS TBNA was nondiagnostic subsequently underwent surgical biopsy.All the patients had a minimum of 6 months clinical and radiologic follow-up.Results EBUS-TBNA was performed on a total of 88 lymph node stations in 38 patients.Of the enlarged lymph nodes,60(68.18％) were located in the mediastinal region and the remaining 28 (31.82 ％) around the hilum or interlobar area.Of the 38 patients,EBUS-TBNA achieved definitive diagnosis in 34 patients(89.47％).EBUS was well tolerated by all of the patients with no complications.Conclusion EBUS-TBNA is a safe procedure with a high yield for the diagnoses of thoracic tuberculosis.

BACKGROUND:Heart valve surgery combined with coronary artery bypass grafting has been gradual y used for treatment of coronary heart disease combined with cardiac valve disease.
OBJECTIVE:To retrospectively summarize the experience of combined coronary artery bypass grafting and valvular procedure.
METHODS:Total y 51 patients who underwent combined heart valve surgery and coronary artery bypass grafting were retrospectively analyzed, including 10 cases with aortic valve replacement, 14 cases with mitral valve replacement, eight cases with mitral valve replacement combined with tricuspid annuloplasty, four cases with aortic valve and mitral valve replacement, three cases with aortic valve and mitral valve replacement combined with tricuspid annuloplasty, seven cases with mitral valvuloplasty, and five cases with mitral valvuloplasty combined with tricuspid annuloplasty.
RESULTS AND CONCLUSION:Biovalve replacement was performed in nine patients, mechanical valves replacement in 31 cases, mitral valvuloplasty in 11 cases and tricuspid annuloplasty in 16 cases. There were total y 109 bypass graft vessels, and the average number of coronary artery bypass grafts was (1.92±0.73) branches. Four cases died within 30 days postoperatively, and 47 patients were successful y discharged from the hospital. Forty-five of 47 discharging patients were fol owed for 3-48 months. One case died of cerebral infarction within 6 months postoperatively, and another case died of cardiac dysfunction over 1 year after operation. The heart function of 45 survival patients was significantly improved. The comprehensive analysis showed that improving the heart function preoperatively, strengthening myocardial protection, shortening operation and myocardial ischemia time, and complete revascularization are the key factors for successful operation.

Objective To investigate the efficacy and safety of CT-guided radiofrequency ablation (RFA) in treating lung tumors. Methods A total of 33 patients with lung cancer (35 lesions in total), who were admitted to authors’ hospital during the period from May 2007 to August 2013 to receive treatment, were enrolled in this study. RFA was carried out in all patients. After RFA the patients were followed up regularly (once every 3 months) to evaluate the therapeutic efficacy and the adverse reaction. The deadline for the following-up was November 2013, or to the time when tumor progression occurred. Results Of the total 34 lesions in 32 patients who had received RFA and had complete follow-up data, the one-year local control rate was 85.3%. The average one-year progression-free survival rate was 75.0%, among them 15 cases with primary lung cancer had a mean one-year progression-free survival rate of 80.0% and 17 cases with metastatic lung cancer had a mean one-year progression-free survival rate of 70.6%. The overall median progression-free survival (PFS) was(18.0±1.3) months. No obvious correlation existed between PFS and age, sex, tumor size, pathological type, clinical stage (P<0.05). The main adverse reactions of RFA were pain, hydrothorax and pneumothorax; no serious life-threatening complications occurred. Conclusion RFA is a safe, effective and minimally-invasive treatment for lung cancer, regardless of early stage or late stage of the tumor.
