Objective Konno-Rastan procedure is one option to cope with complex multilevel left ventricular outflow tract obstruction (LVOTO),which continues to pose a serious challenge to cardiac surgeons.The aim of this study is to retrospectively analyse indications for Konno-Rastan procedure,and to review the safeguards and pitfalls.Methods Between January 1996 and August 2012,totally 13 children with multilevel LVOTO underwent Konno-Rastan procedure.There were 8 boys and 5 girls.Age at surgeries ranged from 5 to 13 years,and weight from 12 to 51 kg with median of 21 kg.The pathology of this cohort includes:8 cases of congenital aortic valvular stenosis,3 cases of congenital aortic valvular stenosis combined with supravalvular stenosis,1 case of congenital aortic stenosis combined with VSD,coarctation and RVOT obstruction,1 case of aortic stenosis s/p percutaneous balloon aortic valvuloplasty.All patients have secondary diffuse tunnel LVOTO.Diameter of aortic ring ranges from 12.0 to 16.4 mm,and pressure gradient across the stenotic region ranges from 90-151 mm Hg.8 cases were implanted with St.Jude AG19 while 5 cases implanted with St.Jude AG17.Results All 13 cases survived.The 4th patient was implanted permanent epicardial pacemaker for transient Ⅲ AVB.The 4th and 5th patients were found residual ventricular septal repture at the nadir of ventricular incision,one underwent redo procedure while another is being followed up.All cases take cumadine to sustain INR at 1.8-2.5.No death emerges during follow-up period.The motality is 0％,the incidence rate of B is 7.7％,residual VSD 15.4％ and endocarditis 7.7％.Conclusion Konno-Rastan procedure is a promising techi.to relieve LVOTO.However,this complex procedure may lead to several fetal complications.Success of the surgery demands perfect operations.

Objective To evaluate the diagnostic value of multi-slice spiral CT (MSCT) in classifying coronary arteries of complete transposition of great arteries (D-TGA). Methods The clinical and imaging data of 367 patients with D-TGA who had undergone MSCT examination from March 2005 to June 2015 were retrospectively analyzed. The origin and course of the coronary arteries of the patients were classified according to the Marie Lannelongue classification. There were four patterns of courses: normal, looping, intramural and miscellaneous. And the four patterns were subdivided into eleven subgroups. The anatomic classification of coronary arteries in D?TGA were recorded, and the ratio of descriptive statistics was used according to categorical variable data. Results All the origin and course of the coronary arteries could be clearly displayed on MSCT. Of 367 patients with D-TGA, 209 cases (56.95%) were normal course (typeⅠ), 138 cases (37.60%) were looping course (typeⅡ), 16 cases (4.36%) were intramural course (typeⅢ), and 4 cases (1.09%) were miscellaneous course (typeⅣ). In looping course, the posterior looping (typeⅡA), anterior looping (typeⅡB) and double looping (typeⅡC) were found in 63 cases (17.17%), 30 cases (8.17%) and 45 cases (12.26%), respectively. The ratios of the anatomic classification of looping courses wereⅡA-1 44(11.99%),ⅡA-2 19(5.18%),ⅡB-1 12(3.27%),ⅡB-2 8(2.18%),ⅡB-3 10(2.72%),ⅡC-1 25 (6.81%),ⅡC-2 17(4.63%),ⅡC-3 3(0.82%). Conclusions MSCT is an effective technique to visualize and classify the coronary arteries in patients with D-TGA. And it is helpful for successful transfer of the coronary arteries and reducing the rate of coronary events after operation.

Objective Retrospectively analyze surgical correction supracardiac total anomalous pulmonary venous con-nection (TAPVC) using sutureless technique to prevent post-repair pulmonary vein stenosis. Methods Between December 2007 and December 2008, 25 children cases of total anomalous pulmonary venous connection underwent primary surgical cor-rection. The anatomic types of TAPVC were supra cardiac in nine patients, inha cardiac in one, mixed in 3 and intra cardiac in 12. Five of nine supra cardiac TAPVC underwent correction using sutureless technique. There were 2 male and 3 female. Their age at surgeries ranged from 2 months to 13 years, and the body weight were from 4.5 kg to 2.1 kg with an average of (7.9±6.4) kg. After median sternotomy and opening the pericardium, the heart was arrested by delivering cold crystal ear-dioplegia. The heart was then positioned toward the patient' s right and under the right henri sternum. A generous incision across the posterior wall of the left atrium and one on the common pulmonary vein was made. The latter was extended upwards to the midpoint of the vertical vein. The left atrium was subsequently connected to the pulmonary venous confluence by suturing the edge of the atrium to the posterior mediastinal pericardium that surrounding the common pulmonary vein and the vertical vein with 7-0 PDS. The vertical vein was partially ligated after conclusion of CPB, leaving a diameter of 5mm shunt. Routine follow-up with echocardiogram were at diacharging, 3 months, 6 months and 1 year after surgery. Results All 5 cases survived uneventfully excopt 1 baby on ventilation over 7 days after surgery, who had bilateral lung consolidation before the operation. Echocardiogram showed satisfactory results with maxium velocity acrossing the anastomosis of 0.65 -0.85 m/s. Conclusion Sutureleas technique can avoid trauma to the pulmonary venous endothelium and minimize the tension of anastomasis. It may play an important role to prevent post-repair pulmonary vein stenosis. More patients with long-term follow-up are necessary to draw a definite conclusion of this technique.

Objective To investigate the efficacy of hyperbaric oxygen combined with donepezil in the treat-ment of patients with vascular dementia(VD). Methods Sixty-four patients with VD were randomly divided into a control group(donepezil group,n=32)and a treatment group(hyperbaric oxygen combined with donepezil,n=32).The course of treatment was 12 weeks.All patients were tested using the Mini-Mental State Examination(MMSE)and Hasegawa's dementia scale(HDS)before and after treatment. Results After 12 weeks of treatment,the MMSE scores and HDS scores of patients increased significantly in both the control and treatment groups.There were signifi-cant differences between the control and treatment groups in terms of MMSE and HDS scores.Conclusion Hyperbar-ic oxygen combined with donepezil could significantly improve cognition in VD patients.

Objective To investigate the relationship between nutritional status and quality of life ( QOL) in patients with nasopharyngeal carcinoma undergoing concurrent chemoradiotherapy, and to identify the optimal indices of body composition for evaluation of malnutrition. Methods Based on the European Society Parenteral and Enteral Nutrition ( ESPEN) consensus on the diagnosis of malnutrition and patient?generated subjective global assessment (PG?SGA), a prospective study was performed in 48 patients with nasopharyngeal carcinoma who received concurrent chemoradiotherapy in our hospital from 2014 to 2015. Changes in body composition and nutritional status were evaluated in those patients. The relationship between nutritional status and QOL was studied. The predictive factors for nutritional status in patients with nasopharyngeal carcinoma were explored. The correlation between datasets was evaluated by the Pearson correlation coefficient. The influencing factors for nutritional status were analyzed by Logistic regression. Results During concurrent chemoradiotherapy, some indices of body composition, including weight, body mass index ( BMI) , fat mass index ( FMI) , fat?free mass index ( FFMI) , body cell mass ( BCM) , skeletal muscle mass ( SM) , and phase angle ( PA) had different degrees of reduction ( P=0?00) , while the PG?SGA score gradually increased. The incidence of malnutrition in patients with nasopharyngeal carcinoma during radiotherapy was 2?1%?39?6% based on 2015 ESPEN consensus on the diagnosis of malnutrition and 12?5%?41?7% based on PG?SGA. These two methods showed good agreement at the fourth and sixth weeks of radiotherapy ( Kappa=0?911;Kappa=0?957) . The changes in QOL score were correlated with changes in FFMI and weight during radiotherapy ( r= 0?805, P= 0?00;r= 0?777, P= 0?00 ) . Logistic regression indicated that age, FMI, and FFMI were influencing factors for nutritional status ( P= 0?035, 0?013, 0?043) . Conclusions Patients with nasopharyngeal carcinoma have substantial nutritional deterioration during chemoradiotherapy. The nutritional status is closely associated with QOL. A prediction model of nutritional status can provide a comprehensive and accurate judgment of nutritional status in patients.

Objective The results of repair for TOF with anomalous coronary artery(ACA) were studied to determine the incidence of coronary anomalies and evaluate surgical strategy choicesas well as postoperative outcomes.Methods From January 2008 to August 2014,1142 consecutive patients underwent repair of TOF including 44 patients with TOF and ACA:single coronary artery in 15,dual anterior descending coronary in 15,single left anterior descending coronary arising from the rightcoronary artery in 3 and the other ACA in 5.The median age was 5.7 years (range,1 month-27 years),and the median weight was 16.0 kg(range,4.5-51.0 kg).Surgical procedure was selected according to the extent of right ventricular outflow tract (RVOT) obstruction and distribution of the ACA.Results There was one operative death.No deaths during the follow-up period in the other 37 patients.Single patch techniquewasperformed in 15.RVOT residual obstruction detected in 7 who without transannular patch,and one need reoperation;Two patch technique was performed in 6,and 3 of them required an additional RV-PA(pulmonary artery) tube because of RVOT residual obstruction during the operation;Double oullet technique was in 6.No tube stenosis occurred in follow-up period time;PA translocation technique was in 11.The right PA stenosis was detected in 4;ACA was ligated and divided in 3,then RVOT reconstruction was performed.Conclusion The combination of ACA is not a contraindication to primary repair of TOF.But there are many anatomiacal variations of ACA,and the accuracy of preoperative diagnosis is low.So proper selection of surgical approach should be individualized based on the careful intraoperative identification of the distribution of the ACA as well as the location and degree of the RVOT obstruction.
