ObjectiveTo introduce the surgical method and effectiveness of repairing skin and soft tissue defect in the palm or dorsum of the hand and forearm with epigastric bilobed flap. MethodsBetween October 2010 and December 2013, 4 male patients with skin and soft tissue defect in the palm or dorsum of the hand and forearm were treated, aged from 36 to 62 years. Of them, 3 cases had degloving injury caused by machines and 1 case had necrosis of fingers and skin after surgery of crush injury. The time from injury to hospitalization was from 3 hours to 15 days. Among the 4 cases, the size of palmar defect was 7 cm×4 cm to 16 cm×6 cm, and the size of dorsal defect was 10 cm×7 cm to 20 cm×10 cm. The epigastric bilobed flap was designed based on the axial vessel which was formed by inferior epigastric artery, superior epigastric artery, and intercostals arteries. The size of flap ranged from 12 cm×4 cm to 18 cm×6 cm in the vertical direction, 15 cm×8 cm to 22 cm×11 cm in the oblique direction. The donor site was directly closed. The pedicles were cut at 22 to 24 days after repairing operation. ResultsAll the flaps survived well with the wound healing by first intention. Four patients were followed up 3 months to 1 year and 2 months. The other flaps had good appearance and texture except 1 bulky flap. The flap sensation basically restored to S2-S3. The function of the hands recovered well. ConclusionSkin and soft tissue defect in the palm or dorsum of the hand and forearm can be repaired with the epigastric bilobed flap, because it has such advantages as big dermatomic area and adequate blood supply. Besides, the operation is practical, safe, and simple.
ObjectiveTo investigate the effect and incidence of residual leakage after surgical repair of large ventricular septal defects with moderate to severe pulmonary hypertension using cross-linkage mattress suture, a suture method invented by us, as compared with interrupted mattress suture. MethodsWe retrospectively analyzed the clinical data of 41 patients of large ventricular septal defect with moderate to severe pulmonary hypertension underwent surgery using cross-linkage mattress suture in Beijing Anzhen Hospital from February 2011 through April 2013. The 41 patients were as a cross-linkage group (average age 18.7±12.3 years, the ratio of male to female 31:10). Another 41 patients, who were repaired using interrupted mattress suture, were retrospectively chosen by matching age, size and location of the defects, pulmonary artery pressure and vascular resistance with members from the cross-linkage group, and were assigned as a control group (average age 17.4±11.8 years, the ratio of male to female 31:10). ResultsThere was no operative mortality and no new perioperative atrioventricular conduction block. Postoperative echocardiography revealed the incidence of residual leakage was 31.7% (13/41) in the control group, 0% (0/41) in the cross-linkage group with a statistical difference (χ2=13.164, P=0.000). With a follow-up of 18.2±6.1 months, no late death and no new atrioventricular conduction block occurred. There was no statistical difference in New York Heart Association functional class or pulmonary artery pressure measured through echocardiography between the two groups. While there was a statistical difference in incidence of residual leakage between the the cross-linkage group and the control group (0% (0/41) versus 26.8% (11/41), χ2=10.499, P=0.001). ConclusionThere is a high incidence of residual leakage after the surgical repair of large ventricular septal defect complicated with moderate to severe pulmonary hypertension using interrupted mattress suture, while the use of cross-linkage mattress suture can effectively reduce the incidence of residual leakage.
Objective To systematically evaluate the clinical effectiveness of platelet-rich plasma (PRP) combined with grafting material for the treatment of periodontal intrabony defects. Methods The following databases such as PubMed, The Cochrane Library, EMbase, CNKI, CBM and WanFang Data were searched on computer from inception to August, 2012 to collect the relevant randomized controlled trials (RCTs) on PRP combined with grafting material versus grafting material alone for periodontal intrabony defects. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the methodological quality of the included studies. RevMan 5.2 software was applied for meta-analysis. Results A total of 11 RCTs involving 342 patients were included. The pooled analysis on 7 RCTs showed that there was a significant difference in lower increase of clinical attachment loss (WMD=0.70, 95%CI 0.51 to 0.90, Plt;0.000 01) between the PRP combined with grafting material group and the grafting material alone group. But there was no significant difference in the gingival recession (WMD= −0.01, 95%CI −0.15 to 0.13, P=0.86). The pooled analysis on 9 RCTs showed that there was no significant difference in the reduction of plaque index (WMD= −0.04, 95%CI −0.09 to 0.02, P=0.20) between the two groups. Conclusion PRP combined with grafting material is superior to grafting material alone in the clinical attachment loss. But, there are no significant differences in gingival recession and plaque index. However, given the limited sample size and incomplete measure indexes of included studies, this conclusion still needs to be further proved by conducting more high-quality and large-scale RCTs.
ObjectiveTo summarize the method and experience in surgical treatment for mesh infection after prosthetic patch repair of ventral hernia. MethodsThe clinical data of 16 patients with mesh infection after ventral hernia repair accepted surgical treatment in our department from June 2007 to May 2010 were analyzed retrospectively. There were 10 males and 6 females, the age range from 24 to 73 years with an average 45.2 years. The patients with mesh infection included 11 cases of infection after incisional hernia repair, 4 cases of infection after abdominal wall defects repair caused by abdominal wall tumor resection, 1 mesh infection combine with urinary fistula caused by parastomal hernia of ileal neobladder repaired by using prosthetic patch. Clinical manifestation included mesh exposion, abscess, chronic sinus, and enterocutaneous fistula. All patients accepted local treatment of change dressing by primary operative surgeon, but the wounds didn’t heal about 3 to 24 months. Then the patients performed radical removal of infected mesh and abdominal wall reconstruction. ResultsAll patients accepted affected mesh removal successfully. Five patients performed abdominal wall reconstruction by using components separation technique. Four cases accepted abdominal wall repair by using polypropylene mesh. Five patients performed abdominal wall repair by using human acelluar dermal matrix. One case accepted change dressing and vacuum aspiration on the infected wound surface without reconstruction. And one case closed the wound immediately after infected mesh removal. The postoperative hospitalization time was 9 to 25 d (average 14 d). Thirteen patients recovered with primary wound healing. The other 3 cases recovered with second healing by local change dressing. All patients were followed up from 6 to 34 months (average 22 months), no abdominal wall hernia recurrence occurred. ConclusionsIt is very difficult to deal with mesh infection after prosthetic patch repair of abdominal wall hernia or defect. The surgical treatment should be done according to specific condition of each individual so as to acquire satisfied results.
Test of tissue tolerance to domastic prosthetic materials (carbon fiber mesh, siliconized velvet, silk cloth and dacron cloth) as a subcutaneos transplant was performed in the adcominal wall of rabbit. These implants and their surroundding tissues were excied for studies at second , fourth, eighth and the twelfth weeks after operation. Ratio of fibroblast count to inflammatory cells count which is a common parameter of tissue tolerance was calculated in these four groups. The result shows that fibroblastic cell reaction elicited by carbon fiber mesh is the greates among the four prosthetic materials, the second one is dasron cloth. The inflammatory cell reaction elicited by silk is the greatest among the four materials, the second is carbon fiber mesh, and the dacron cloth the least. Tissure tolerance of dacron cloth is the best in the four prosthetic materials for implantation while sick is the worst.
Objective To investigate surgical strategy for the treatment of muscular ventricular septal defect （MVSD） in infants with multiple ventricular septal defects（VSD）. Methods Clinical data of 46 infants with multiple VSD who underwent surgical repair in Shanghai Children’s Medical Center from January 2010 to April 2012 were retrospectively analyzed. There were 24 males and 22 females with their age of 8±6 months and body weight of 6.1±1.9 kg. All the patients received one-stage surgical repair，among whom MVSD of 10 patients was not found and repaired during the surgery. MVSD was repaired by surgical suture in 19 patients，hybrid repair under direct vision in 12 patients，and hybrid repair via the right ventricle in 5 patients. All the patients were regularly followed up after discharge by chest X-ray，ECG and color Doppler echocardiography to observe the closure of MVSD and the presence of residual shunt. Results All the 46 patients with multiple VSD survived their surgery without perioperative death. Three patients undergoing hybrid repair under direct vision received delayed sternal closure. One patient undergoing hybrid repair under direct vision had postoperative cardiac dysfunction. All the 46 patients were followed up for 1-17 months. Twenty-three patients had residual shunt of varying degrees during follow-up，and most of the MVSD of patients with residual shunt were ＜4 mm，who were receiving further follow-up and evaluation. Conclusion Appropriate surgical strategies can be applied according to specific surgical views during the operation for the treatment of MVSD in infants with multiple VSD，and satisfactory clinical outcomes can be achieved.
Objective To compare surgical results between real-time three dimensional echocardiography（RT-3DE） guided closure of atrial septal defect （ASD） through a right minithoracotomy and traditional surgical repair under cardiopulmonary bypass （CPB）. Methods Sixty-four patients with secundum ASD received surgical repair in the First People’s Hospital of Honghe Autonomous Prefecture from April 2009 to April 2012. According to different surgical approach, all the patients were divided into group A and B. In group A, 35 patients underwent traditional ASD repair under CPB including 20males and 15 females with their age of 12-56 （16.4±4.0） years. In group B, 29 patients received real-time RT-3DE guidedASD closure through a right minithoracotomy without CPB, including 20 males and 15 females with their age of 15-50 （18.5±0.2） years. Operation time，postoperative mechanical ventilation time，hospital stay，chest drainage，mortality，morbidity and follow-up outcomes were compared between the 2 groups. Results Operation time （110.47±35.90 minutesvs. 159.32±20.60 minutes），postoperative mechanical ventilation time （10.40±22.30 hours vs. 16.40±12.20 hours），chestdrainage （106.71±85.20 ml vs. 146.70±75.63 ml）and postoperative hospital stay （4.0±1.0 days vs. 7.0±1.0 days）ofgroup B were significantly shorter or less than those of group A. In group A, 1 patient died postoperatively and 7 patientshad postoperative complications. In group B, there was no in-hospital mortality and 3 patients had postoperative complications.Postoperative morbidity of group A was significantly higher than that of group B （20.0% vs. 10.3%，P＜0.05） . ConclusionFor ASD patients with definite surgical indications，RT-3DE guided ASD closure through a right minithoracotomy has more advantages over traditional surgical repair under CBP.
Abstract： Objective To summarize surgical results of secondary subaortic stenosis （SSS） after congenital heart disease （CHD） operations，and analyze the pathogenesis of SSS. Methods We retrospectively analyzed clinical data of 19 patients who underwent surgical repair for SSS in Guangdong General Hospital from 1st June 2008 to 31st December 2012. There were 10 males and 9 females. CHD types included double outlet right ventricle，ventricular septal defect and partial atrioventricular septal defect，et al. The median age of the patients when they received their first CHD operations was 4 months （15 days to 5 year and 11 months）. The median age of the patients when they received SSS repair was 5 years and 3 months （1 year to 15 years and 3 months）. The median time interval from CHD operation to SSS repair was 4 years and 10 months （8 months to 13 years and 11 months）. Results All the patients successfully received their SSS repair. There was no surgical death in this study. Median cardiopulmonary bypass time was 79 （39 to 172） minutes，and median aortic cross-clamp time was 42 （22 to 124） minutes. Median postoperative hospital stay was 7 （5 to 9） days. Postoperatively， 1 patient required permanent pacemaker implantation. All the patients were followed up after discharge for a median durationof 1 year and 10 months （5 months to 4 years and 4 months） . During follow-up， none of the patients had any clinical symptom，their heart function was normal，and there was no late death. One patient received another subaortic stenosis repair for gradually aggravating left ventricular outflow tract stenosis. Conclusions SSS is very rare after CHD operations. The pathogenesis of SSS is perhaps related to abnormal blood flows in the left ventricular outflow tract after CHD operations. The pathogenesis time of SSS and types of CHD leading to SSS cannot be predicted. Subaortic stenosis repair is a simple and safe procedure for SSS，but postoperatively left ventricular outflow tract stenosis may appear and aggravate again.
Objective To evaluate long-term outcomes of surgical repair for pulmonary atresia with ventricular septal defect （PA-VSD） and major aortopulmonary collateral arteries （MAPCAs）.?Methods?We retrospectively analyzed the clinical data of 29 patients with PA-VSD and MAPCAs who underwent surgical repair in Shanghai Children’s Medical Center from February 2001 to February 2010. There were 13 patients in the one-stage operation group and 16 patients in the staged operation group. There were 8 males and 5 females in the one-stage operation group with their age ranging from 8 to 168 （26.0±17.0）months. There were 9 males and 7 females in the staged operation group with their age ranging from 4 to 149 （26.5±15.8）months. Eight patients underwent their second operation with the time interval between the two operations ranging from 14 to 40 （28.3±11.7） months. For MAPCAs， 9 patients underwent unifocalization， 16 patients underwent ligation or occlusion via cardiac catheterization， and the other 4 patients left them open or unrepaired. We compared postoperative mortality， complications， long-term outcomes， and quality of life between the two groups. Quality of life of the 29 PA-VSD patients was measured according to Pediatric Quality of Life Inventory version 4.0 and compared with 100 children from a kindergarten as a control group.?Results?Postoperative mortality of one-stage operation group was significantly higher than that of staged operation group at 15.4% （2/13） vs. 0.0% with χ2=4.12 and P=0.04. There was no statistical difference in the rate of postoperative complications between the two groups at 75.0% （9/12） vs. 56.2% （9/16） with χ2=0.51 and P=0.47. Patients were followed up for 3 to 88 months， and the follow-up mortality of one-stage operation group was not significantly higher than that of staged operation group at 27.3% （3/11） vs. 6.2% （1/16） with χ2= 2.28 and P=0.13. There was no statistical difference in overall quality of life score between one-stage operation group and staged operation group （66.7±8.6 vs 70.2±13.0， t?=?-0.71， P=0.48） . The overall quality of life score of PA-VSD patients was significantly lower than that of control group （68.7±11.2 vs. 77.8±15.7， t?= 3.14， P=0.01）， mainly because the physical functioning score of PA-VSD patients was significantly lower than that of control group （57.7±11.7 vs. 83.0±19.6， t?=5.67， P=0.00）， but there was no statistical difference in emotional well-being score， social functioning score， and school functioning score between PA-VSD patients and the control group.?Conclusion It is the key to analyze different pulmonary artery conformation， choose individualized surgical procedure and properly manage MAPCAs so as to reduce postoperative mortality and complications of surgical repair for patients with PA-VSD and MAPCAs.
Pulmonary atresia (PA) with ventricluar septal defect(VSD) is a complex congenital heart disease. The lack of knowledge on embryology, anatomy and pathophysiology of this disease with or without heterogenetic major aortopulmonary collateral arteries(MAPCA)leads to chaos of its surgical classification and management as well as poor results of surgical management. The operative technique in this field has been advancing a lot since the innovation of unifocalization. The surgical result is getting better and better, boosted by the updating of the principle and knowledge, but there is still a large room for progress. We reviewed the literatures on classification,surgical strategy, procedures and operationrelated issues and put them together here to delineate its past, present and future.
