Objective To summarize the experience of open heart operation on neonates with critical and complex congenital heart diseases and evaluate the methods of perioperative management. Methods From May 2001 to January 2003, 12 patients of neonates with congenital heart diseases underwent emergency operation. Their operating ages ranged from 6 to 30 days, the body weights were 2.8 to 4.5 kg. Their diagnoses included D-transposition of the great arteries in 4 cases, ventricular septal defect with atrial septal defect in 5 cases, complete atrioventricular septal defect, obstructed supracardiac total anomalous pulmonary venous drainage and cardiac rhabdomyomas in 1 case respectively. 12 cases were operated under moderate or deep hypothermic cardiopulmonary bypass. Results All cases were observed in ICU for 2-11 days and discharged 7-19 days after operation. The postoperative complications included low cardiac output, mediastinal infection, respiratory distress syndrome, systemic capillary leak syndrome and acute renal failure. All cases were cured and the follow-up (from 6 months to 2 years) showed satisfactory outcome. Conclusion A particular cardiopulmonary bypass and proper perioperative management is very important to ensure the successful outcome. Peritoneal dialysis is an effective and safe method for treating acute renal failure after cardiac operation in neonates.
Objective To explore the feasibility of transcatheter closure of congenital heart disease (CHD) under the guidance of transthoracic echocardiography (TTE). Methods A total of 37 patients with CHD who received transcatheter closure under the guidance of transthoracic echocardiography from November 2013 through November 2015 in our hospital were recruited. There were 15 males and 22 females, aged 1 to 16 years. Among them 32 patients suffered atrial septal defect and 5 patients had patent ductus arteriosus. The transcatheter closure of CHD was performed under the guidance of TTE. The patients underwent echocardiography follow-up at one, three and six months after surgery. Results Closure devices were successfully implanted in 37 patients under TTE guidance. The procedure was simple and safe. During the follow-up, no severe complication such as valvular injury, pericardial effusion, residual shunt and peripheral vascular injury occurred. Conclusion Transcatheter closure of CHD under TTE guidance is a feasible method and worth further clinical application.
ObjectiveTo observe the mutation and expression of Nkx2.5 in congenital heart disease patients with diminutive pulmonary blood. We preliminarily explored the association between Nkx2.5 gene and pathogenesis of congenital heart disease patients with diminutive pulmonary blood. MethodsFifty six patients of congenital heart disease with diminutive pulmonary blood in the first affiliated hospital of Bengbu medical college and Anhui province children, s hospital between May 2012 and May 2014 were as an experimental group. Sixty three patients of ventricular septal defect were as a control group. In the trial group, there were 30 males and 26 females averagely aged 5.82± 4.23 years ranking from 6 months to 14 years. In the control group, there were 36 males and 27 females averagely aged 6.93± 4.56 years ranking from 6 months to 14 years. Before operation, peripheral venous blood of all the patients were collected. We used polymerase chain reaction combined with DNA sequencing technology to detect Nkx2.5 gene exon sequence and to analyze the association between Nkx2.5 gene mutation and congenital heart disease with diminutive pulmonary blood. And we got some hypertrophic myocardial tissue from right ventricular outflow tract in the operation, whose size was 0.5× 0.5× 0.5 cubic centimeter. And we extracted myocardial tissue RNA. The expression changes of Nkx2.5 gene mRNA were detected by real-time fluorescence quantitative polymerase chain reaction technique. ResultsThere was no mutations tested out in the peripheral venous blood in both two groups. The expression of mRNA in Nkx2.5 gene of the trial group was lower than that in the control group with a statistical difference. ConclusionNkx2.5 gene mutation may be associated with multiple factors. The occurrence of congenital heart disease with diminutive pulmonary blood may be related with a decline of Nkx2.5 gene expression in the myocardial tissue.
Objective To investigate the value of systemic-normothermic/cardiac-hypothermic cardiopulmonary bypass（CPB）on operation of congenital heart disease. Methods Thirty patients of congenital heart disease were randomly divided into two groups, the normothermia group（n=15）and hypothermia group（n=15）. The changes of CPB time, aortic cross-clamp time,operation time and postoperative drainage and the value of blood cell were observed. Results The duration of CPB （37. 5 ±11. 6rain vs. 51. 6± 12. 0 min, P〈0. 05） and operation time （2.2± 0.6h vs. 2. 7±0. 5h, P〈0. 01） in normothermia group were shorter than those of hypothermia group statistically, the differences of postoperative drainage and the value of blood cells between two groups were not statistically significant. Conclusion The use of systemic-normothermic/cardiac-hypothermic CPB on operation of congenital heart disease shows that the time of operation is shorter remarkly , and it could be clinically used safely.
OBJECTIVE To sum up the experience of diagnosis and treatment of intrinsic upper gastro-intestinal membrane, 13 cases in children were studied retrospectively. METHODS There were 10 boys and 3 girls, the major symptoms were vomiting and epigastric distension. Eleven cases were treated by membranectomy with intestinal plasty, and 2 cases were treated by retrocolic side to end duodenojejunostomy. RESULTS All cases had good results without severe complications. CONCLUSION The children who have typical symptom of upper digestive tract should be considered duodental and upper jejunal membrane, and should be proved by contrast radiology. The membranectomy with intestinal plasty is the better operative method.
Objective To explore the feasibility and safety of laparoscopic cyst resection and Roux-en-Y hepatojejunostomy in treatment for adult congenital cholangiectasis and to compare the therapeutic effects of laparoscopic procedure with conventional open procedure. Methods The clinical data of 33 adult patients with congenital cholangiectasis from May 2008 to September 2011 in the department of general surgery of Shengjing Hospital of China Medical University were retrospectively analyzed. Fourteen patients received laparoscopic procedure （laparoscopic group），whereas the other 19 patients received conventional open procedure （conventional group）. Results All the operations were carried out successfully through laparoscopic procedure. The mean time of operation in the laparoscopic group was significantly longer than that in the conventional group （195min versus 130min，P＜0.01）. The average intraoperative blood loss in the laparoscopic group was significantly less than that in the conventional group （80ml versus 270ml，P＜0.01）. In contrast，the mean time of bowel peristalsis recovery and postoperative hospital stay in the laparoscopic group were significantly shorter than those in the conventional group （time of bowel motion recovery：76h versus 104 h，P＜0.01；hospital stay：6.1 d versus 9.6 d，P＜0.01）. There were no differences in the early complications between two groups （P＞0.05）. Conclusions Totally laparoscopic treatment for congenital cholangiectasis in adult is feasible and safe. It is worth to be generally applied because of its minimal invasion and fast postoperative recovery.
Twenty five children with congenital biliary dilatation were treated with hepatico-jejuno-duodenostomy following excision of choledochal cysts between 1983 and 1985. The age ranged from two months to eleven years. The last follow-up ranged from 6-9 years (mean 7.5 years). All patients were free of jaundice with normal growth and development and none had peptic ulcer. The results from the last follow-up was better than that of the first one. This procedure was safe, effective and physiologically appealing.
