Acetabuloplasty was used to treat 62 cases (76 hips) of congenital dislocation of hip in older children, with a period of follow-up for 1 to 7 years. The good results from operation rated 81.7 percent. It was considered that this type of operation could fulfil the physiological requirements, as the femoral head replaced into the acetabulum would accomplish the following benefits from establishing a stable joint, reducing the lumbar lordosis and minimizing development of hip and low back pain. The technique ...
In 1984, according to the criteria of the classifieation for congenital hand deformity which wasput out by the International Hand Surgery Committee, we had made an investigation for congenitalhand deformity among 318066 newborns in Shanghai. It was found that the inctdence of a congenitalhand malformation was 0. 0808 percent among the total newborns. The congenital malformation ofthe thumb was 37. 74 percent of all deformities of the hand. According to the statistical analysis, we ...
Objective To summarize the experience of surgical treatment of congenital heart diseases through right axillary mini-thoracotomy and analyse related problems. Methods Two hundred and twenty-four patients of congenital heart diseases underwent open heart surgery under cardiopulmonary bypass （CPB） through a right axillary mini-thoracotomy（3rd or 4th intercostal）. Among them repair of ventricular septal defect （VSD） in 168, repair of atrial septal defect （ASD） in 48, total correction of tetralogy of Fallot （TOF） in 6, double-outlet right ventricular in 1 and Ebstein syndrome in 1. Results There was 1 postoperative death （0.45%）, the cause of death was acute pulmonary edema. Postoperative complication occurred in thirteen cases （5.8%）. There were no significant changes in CPB time, aortic cross clamping time, ventilating time and hospital stay days between right axillary minithoracotomy and median sternotomy at the same period （Pgt;0. 05）, but the bleeding volume both intraoperative and postoperative in the patients of right axillary mini-thoracotomy were significantly less than those in the patients of median sternotomy （Plt;0. 01）. Two hundred and fourteen patients were followed up （follow-up time from 2 months to 7 years）, 3 of them had early mild cardiac function insufficiency（ejection fractionlt;0. 50）, small residual shunt were found in 2 patients after VSD operation and the others recovered satisfactorily. Conclusion There were merits in right axillary mini-thoracotomy approach for treatment of properly selected congenital heart diseases; safe and reliable, low operative bleeding volume, and good results of aesthetics. But the use of this incision for repair of TOF and more complex congenital heart diseases should be careful.
Objective To explore the clinical effect of combining medial and lateral canthoplasty with blepharoptosis correction at onestage for congenital blepharophimosis syndrome. Methods From January 2002 to May 2006, 26 patients(52 sides) with congenital blepharophimosis syndrome were treated. There were 16 males and 10 females, aging from 3 to 35 years (mean 8.5 years). They were all bilateral blepharoptosis significantly. The palpebral muscle force was 03 mm; the transverse dimension and vertical dimension of the palpebral fissue were 13-22 mm and 2-4 mm; the intercanthal distance was 33-44 mm; the levator function was 1-3 mm. Results Twenty-six patients underwent medial canthoplasty and blepharoptosis correction, of them, 12 patients were also given lateral canthoplasty at one-stage. The postoperative transverse dimension and vertical dimension of the palpebral fissue were 6-8 mm and 24-32 mm, respectively. The intercanthal distance was 29-34 mm. The levator function was 46 mm. The supratarsal fold in the upper lid was natural. With a follow up of 3 months to 4 years，all patients were satisfied with their results. Conclusion One-stage surgical treatment of combining medial and lateral canthoplasty with blepharoptosis correction can achieve good result for blepharophimosis syndrome with a shortened treatment time.
Objective To summarize the clinical characteristics, diagnosis and treatment of Bochdalek hernia in neonates and infants. Methods The data of 15 neonates and 10 infants with Bochdalek hernia，undergoing the normal diagnosis and surgical repair from August 1983 to June 2004, were retrospectively reviewed. Location was left in 22 cases and right in 3 cases. Twenty-four cases were treated by operation and 1 case died of respiratory failurebefore operation.Results Before April 1998，7 of 8 (5 neonates，3 infants) cases of Bochdalek hernia stayed healthy and respiratory symptomfree 1 year after operation; they were followed up 1 year and 3 months to 11 years. One premature neonate with Bochdalek hernia died of respiratory failure before operation, and his lung volume was found to be dysplasia. From April 1998 to June 2004, 15（8 neonates，7 infants） of 17 （10 neonates，7 infants）cases of Bochdalek hernia survived postoperatively, while 2 neonates died of respiratory failure. Conclusion The earlier dyspnoea of neonates ofBochdalek hernia occur，the worse their healthy status appear. The standard andtimely surgical repairs could improve the curative ratio. Whether the operationwas suspended depended on the healthy states of babies.
Surgery is still the main treatment for congenital polydactyly, and the aim of surgical reconstruction is to obtain a thumb with excellent function and appearance. A systematic assessment of polydactyly is required prior to surgery, including bone stress lines, joint deviation, joint activity and joint instability, size and development of finger and nail. Bone shape, joint incongruency, and abnormal tendon insertions must be corrected completely, in order to obtain good function and to avoide secondary surgery. Bilhault-Cloquet procedure can reconstruct the size of the finger and nails. Fine manipulation can improve the postoperative nail deformity, so that the reconstructed nail reaches a satisfactory aesthetic score.
Aiming at the problems of obscure clinical auscultation features of pulmonary hypertension associated with congenital heart disease and the complexity of existing machine-aided diagnostic algorithms, an algorithm based on the statistical characteristics of the high-frequency components of the second heart sound signal is proposed. Firstly, an endpoint detection adaptive segmentation method is employed to extract the second heart sounds. Subsequently, the high-frequency component of the heart sound is decomposed using the discrete wavelet transform. Statistical features including the Hurst exponent, Lempel-Ziv information and sample entropy are extracted from this component. Finally, the extracted features are utilized to train an extreme gradient boosting algorithm (XGBoost) classifier, which achieves an accuracy of 80.45% in triple classification. Notably, this method eliminates the need for a noise reduction algorithm, allows for swift feature extraction, and achieves effective multi-classification using only three features. It is promising for early screening of pulmonary hypertension associated with congenital heart disease.
Objective To summarize the clinical outcome and strategy of re-operation on adult and older children patients with congenital heart disease. Methods We retrospectively analyzed the clinical data of 339 patients underwent re-operation in our hospital from January 2010 to December 2014. There were 214 males and 125 females at the mean age of 21.6±12.4 years. According to the pathophysiological result and the difficulty level of operation, patients were divided into a simple re-operation group (n=186) and a complex re-operation group (n=153) . We compared the clinical outcomes of two groups. Results In the simple re-operation group, the rate of mortality was zero and the rate of complications was 5.9%. There was 1 patient of interoperative right atrium injury, 1 patient of extensive hemorrhage, 5 patients of postoperative secondary thoracotomy, 1 patient of hemodialysis, 3 patients of severe infection, and 2 patients of Ⅲ degree atrioventricular blockage. In the complex re-operation group, the rate of mortality was 3.3% and the rate of complication was 30.1%. There were 2 patients of intraoperative coronary artery lesion, 2 patients of aortic injury, 1 patient of pulmonary artery injury, 6 patients of extensive bleeding, 8 patients of postoperative secondary thoracotomy, 13 patients of hemodialysis, 12 patients of severe infection, 5 patients of nervous system complications, 4 patients of Ⅲ degree atrioventricular blockage. Extracorporeal membrane oxygenation (ECMO) applied in 4 patients. Conciusion Complex re-operation is still the influential factor of mortality and complications for patients with congenital heart disease and we should take measures to aviod the mortality and complications.
Objective To investigate the effect of prostaglandin E1 (PGE1) on serum vascular endothelial growth factor(VEGF) in patient with pulmonary hypertension secondary to congenital heart disease and its relation to different pathologic gradings of pulmonary arterioles. Methods Fifty three patients suffering from pulmonary hypertension secondary to congenital heart disease were chosen at random to undergo active tissue test of lung, including 6 patients suffering from severe cyanosis. All of them were intravenously dripped with PGE 1 for 15 days at the speed of 10 15 ng /kg·min, 12 hours a day. Venous blood was taken for study in the morning on the day before infusion, on the 5th day, the 10th day, and the 15th day after infusion. Then the concentration of VEGF was measured by enzyme linked immunosorbent assay (ELISA). Lung biopsy was taken from each patient and pathologic grading performed according to Heath and Edwards pathologic grading. Results Fifty three patients were classified into Grade Ⅴ:9 of them belonged to Grade Ⅰ, 14 to Grade Ⅱ, 19 to Grade Ⅲ, 5 to Grade Ⅳ, the other 6 with severe cyanosis belonged to Grade Ⅴ or even severe than Grade Ⅴ. Before administration of PGE 1, serum VEGF reached the peak while the pathologic grading of pulmonary arteriole was Grade Ⅲ, VEGF level markedly decreased in Grade Ⅳ and Ⅴ. After administration of PGE 1 serum VEGF in Grade Ⅰ showed no difference with that before administration of PGE 1( P gt;0.05), VEGF decreased in GradeⅡ and Ⅲ ( P lt;0.01), slightly decreased in Grade Ⅳ ( P lt; 0.05), while patients greater or equivalent to Grade Ⅴ showed no VEGF change during the course of PGE 1 administration ( P gt;0.05). Conclusions PGE 1 can lower the VEGF level, but the extent closely relates to the degree of pathologic change in pulmonary arteriole. It might be a pre operative parameter for pathologic grading of pulmonary arteriole.
ObjectiveTo summarize surgical treatment experience on unruptured aneurysm of the sinus of Valsalva (SVA). MethodsClinical data of 33 patients with unruptured SVA underwent surgical repair at Fu wai Hospital between February 2007 and January 2012 were retrospectively analyzed. There were 27 males and 6 females with their mean age of 28.5±13.5 years (ranged from 4.5 to 58.0 years). The unruptured SVA originated in the right coronary sinus in 29 cases (87.8%), in non-coronary in 2 cases (6.1%) and in left coronary sinus in 2 cases (6.1%). There were 29 cases with ventricular septal defect and 20 cases with aortic valve insufficiency (AI). ResultsOnly 52.8% of unruptured SVA were correctly diagnosed by echocardiography preoperatively. All unruptured SVA received active surgical management, with no early death after operation. Thirty patients (90.9%) were followed up for 22 to 81 months (mean 42.9±18.8 months) and in NYHA classⅠorⅡ. None SVA recurrence occurred. Postoperative AI could be improved better by using the repair route only through the chamber of right ventricle for patients with unruptured SVA originated in right coronary sinus. ConclusionFor unruptured SVA patients who associated with other kinds of cardiovascular lesions, active surgical repair for unruptured SVA can achieve satisfactory results.
