ABSTRACT
Objective To objectively quantitative assess the visual quality in patients with myopic foveoschisis (MF) using a double-pass optical quality analysis system (OQASⅡ).Methods Sixty-two subjects participated in this cross-sectional,observational study,who were divided into three groups based on the pathologic conditions including myopic fovcoschisis group (MFG),myopic control group (MCG) and normal control group (NCG).Measurements with OQAS Ⅱ were performed for the modulation transfer function cut off frequency (MTFcut-off),the Strehl ratio (SR) and the objective scatter index (OSI).Visual data were analyzed using ANOVA and Pearson's correlation accompanied by logMAR BCVA and axial length (AL).Results The mean values for MTFcut-off,SRand OSIof MFG,MCGand NCG were 18.18±4.81,0.13± 0.03,3.50±0.44;22.87±2.66,0.14±0.02,2.42±0.29;33.68±4.70,0.23±0.02,1.68±0.20 respectively,and statistical difference were proved except SR between MFG and MCG,or BCVA between MCG and NCG (P＜ 0.05).LogMAR BCVA and AL have negative correlations to MTF cut-off (r =-0.928,-0.658;P＜0.05) and SR (r=-0.577,-0.893;P＜0.05) with high coefficients in MFG.Log MAR BCVA has negative correlations to MTF cut-off and SR (r=-0.659,-0.806;P＜0.05) in MCG.Log MAR BCVA has negative correlations to MTF cut-off and SR (r=-0.606,-0.602;P＜0.05) and positively correlated to OSI (r=0.561,P＜0.05) in NCG.Conclusions The mean value of BCVA,MTF cut-off,SR,OSI of myopic foveoschisis patients were lower than those myopic patients without foveoschisis and normal people.there exists a significant negative correlation between Log MAR BCVA,AL to MTF cut-off and SR.Compared with myopic and normal subjects,myopic foveoschisis have lower BCVA,MTF cut off,SR but higher OSI.
ABSTRACT
Objective To evaluate the outcome of endovascular treatment with coarctation of aorta (CoA).Methods Between November 2007 and March 2012,11 patients,including 8 male and 3 female from 17 to 43 years old,with native CoA who were diagnosed by computed tomography angiography accepted the endovascular treatment.The arterial pressure difference between the femoral artery and the narrow segment was measured during the operation,and the stent was released by expanding the balloon.Results Endovascular treatment were successful in all cases without any major adverse events.Significant reduction of systohc blood pressure was observed from (64.09 ± 7.81) mmHg (1 mmHg =0.133 kPa) to (11.18 ± 3.37) mmHg.The mean CoA diameter pre-stent (4.000 ± 0.775) mm,post-stent (17.090 ± 2.427) mm.1 patient associated with patent ductus arteriosis had no persistent left-to-right shunt after covered stent implantation.The follow up range was 33 months.1 patient in simple balloon was retreatment by surgical because of restenosis.And no retraction was observed of 10 patients after stent implantation.Conclusion The early and midterm result of endovascular treatment with CoA is satisfactory,and longer follow-up is needed for its longterm outcomes.
ABSTRACT
Objective To explore the appropriately operative chance , method, and perioperative management of coronary arterybypass grafting (CABG) in the patients with severe left main artery (LMA) stenosis with three-vessel-disease.Methods A total of296 patients with severe LMA stenosis with three-vessel-disease who underwent CABG surgery was analyzed retrospectively from 2003through 2013.Of them, 276 patients underwent conventional coronary artery bypass surgery on pump ( CCABG)and 20 patients underwentoff-pump CABG( OPCAB); 172 Patients was over 60 years old (58.1%)and 246 patients (83.10%) had concomitant diseasesincluding valve lesion, hypertension, diabetes, myocardial infarction, left ventricular aneurysm with septal defect , stroke, renal failure,and cancer.Left internal mammary artery use was in 281 patients (95.1%); and 32 patients were implanted intra-aortic ballonpump(IABP) perioperatively.Results There were 7 cases(2.36 %) death of postoperative low cardiac output , ventricular fibrillation,cerebral infarction, renal failure, and multiple organ failure, respectively.Postoperative complications were low cardiac output ,respiratory failure , ventricular fibrillation, cereboembolism, cardiac tampomade, renal failure, stroke, and multiple organ failure.Afterfollow-up 2 to 84 months, there was 3 death in which 2 death of cardiac factors.Conclusions CCABG was a safe and effectivemethod in patients with severe LMA stenosis with severe three -vessel-disease.Preoperative insertion of IABP can certainly avoid the po -tential operative risk factor and significantly decrease the mortality and morbidity .
ABSTRACT
Objective To summarize the experience in surgical treatment of Ebstein anomaly,and evaluate the therapeutic effect.Methods Thirty-five patients of Ebstein anomaly were treated by operation.New York heart association(NYHA)heart function classⅠ?was in 11 cases,classⅡ?was in 14 cases,class III-Ⅳ?was in 10 cases.The cue of echocardiogram about tricuspid valve regurgitation in 24 cases were severe,5 cases were moderate and 6 cases were mild.Two patients accepted tricuspid valve replacement.Thirty-three cases were accepted tricuspid valve repair and right ventricle folded,in which 2 cases accepted Danielson method,and 31 cases accepted Carpentier method,among them,9 cases accepted one and a half ventricular repair.Associated heart anomaly was corrected at the same time.Results One patient died.There were 2 cases with third degree atrioventricular block after tricuspid valve replacement,2 cases with low cardiac output syndrome and 2 cases with atrial fibrillation combined premature ventricular contraction.The heart was lower by chest X-ray and echocardiogram examination,tricuspid valve regurgitation in 22 cases were disappeared,9 cases were mild,3 cases were moderate.All patients were followed up from 1 month to 7years,tricuspid valve regurgitation in 21 cases were disappeared,12 cases were mild,heart function were class Ⅰ-Ⅱ.Because of heart function aggravation,1 patient was operated again 3 years after operation.Condusions Ebstein anomaly is a rare congenital heart disease,Carpentier method tricuspid valve repair can decrease regurgitation obviously and protect right ventricular function.One and a half ventricular repair should be adopted according to the function of tricuspid valve and right ventricle.
ABSTRACT
Objective To investigate the feasibility of laparoscopic radical gastrectomy for gastric cancer.Methods Laparoscopic radical gastrectomy was performed in 8 cases from Febrary 2005 to April 2005,including radical distal gastrectomy in 6 cases,radical total gastrectomy in 1 case,and radical proximal gastrectomy in 1 case.Results All the 8 patients underwent laparoscopic radical gastrectomy smoothly and no conversion to open surgery was required.The operation time was 340?62 minutes in radical distal gastrectomy,was 362 minutes in radical proximal gastrectomy,and 423 minutes in radical total gastrectomy.The intraoperative blood loss was 100～250 ml(mean,140 ml) in radical distal gastrectomy,300 ml in radical total gastrectomy,and 170 ml in radical proximal gastrectomy.No blood transfusion was needed.The number of havested lymph nodes was 18～37(mean,23).No surgical-related complications occurred.The time to first flatus was 38～56 hours(mean,42.4 hours),and the time to liquid diet was 2～5 days(mean,2.5 days).All the 8 cases were followed for 12～14 months postoperatively and no recurrence or metastasis was observed.Conclusions Laparoscopic radical gastrectomy is a feasible technique for patients with gastric cancer at early stage or early progressive stage.
