Objective To summarize the experience of extraanatomic aortic bypass grafting through median sternotomy for onestage treatment of aortic coarctation and associated cardiac diseases, and to improve surgical effect of the diseases. Methods Between July 1997 and July 2008, 31 consecutive patients(20 male,11 female; age 31.9±11.7 years) with aortic coarctation and associated cardiac anomalies underwent onestage surgical repair through median sternotomy. The associated cardiac anomalies included: aortic valve insufficiency or stenosis(n=22); mitral valve insufficiency or stenosis (n=9); patent ductus arteriosus (n=5); ascending aortic aneurysm (n=4); ventricular septal defect (n=3); coronary artery disease (n=2). Extra-anatomic aortic bypass grafting was used to repair the coarctation. Routing of the grafts was: ascendingto posterior pericardial descending aorta (n=9) and ascendingtoinfrarenal abdominal aorta (n=22). Concomitant cardiac procedures included: aortic valve replacement in 16; Bentall procedures in 6; mitral valve repair or replacement in 9; ascending aortic replacement or aortoplasty in 4; patent ductus arteriosus closure in 5; ventricular septal defect closure in 3 and coronary artery bypass grafting in 2. Results One patient died of septic shock 39 days after operation with an inhospital mortality of 3.2%. Mean systolic blood pressure gradient between upper and lower extremities decreased from 64.2±25.3 mm Hg preoperatively to 13.7±10.2 mm Hg postoperatively (Plt;0.05). Twentyseven patients were followed up from 4 to 73 months, there were no late deaths，reoperations or graftrelated complications. Conclusion Extraanatomic aortic bypass grafting can be performed simultaneously through median approach in patients with aortic coarctation and associated cardiac diseases. It is an effective and safe treatment option for onestage surgical repair in adults and adolescents. Both ascendingto posterior pericardial descending aorta and ascendingtoinfrarenal abdominal aorta bypass have favorable results.
ObjectiveTo investigate the advantage and short- and medium-term effectivenesses of paramedian incision minimally invasive transforaminal lumbar interbody fusion (mini-TLIF) by comparing with open TLIF. MethodsA retrospective analysis was made on the clinical data of 54 patients with single segmental lumbar degenerative disease who accorded with the inclusion criteria between January 2012 and March 2014. Open TLIF was performed in 26 patients (open group), mini-TLIF in 28 cases (minimally invasive group). There was no significant difference in gender, age, disease duration, etiology, and affected segments between 2 groups (P>0.05). The indexes of surgical trauma, systemic inflammatory response, clinical outcome, and interbody fusion rate were compared between 2 groups. ResultsDural rupture occurred in 1 case of open group, L5 nerve root injury in 1 case of minimally invasive group. All patients obtained primary healing of incision. The operation time, intraoperative blood loss, and postoperative drainage of minimally invasive group were significantly lower than those of open group (P<0.05). C-reactive protein, leucocyte count, and creatine kinase-MM (CK-MM) of open group were significantly higher than those of minimally invasive group at 24 hours after operation (P<0.05). At 7 days after operation, the CK-MM of minimally invasive group was significantly lower than that of open group (P<0.05), but no significant difference was found in C-reactive protein and leucocyte count between 2 groups (P>0.05). The follow-up time was 1.2-3.1 years in open group and 1.4-2.9 years in minimally invasive group. At 1 year after operation, the Oswestry disability index (ODI) and visual analogue scale (VAS) scores were significantly improved in 2 groups (P<0.05). Minimally invasive group was better than open group in ODI and VAS score of back pain (P<0.05), but VAS score of leg pain showed no significant difference (P>0.05). According to the Suk interbody fusion standard, solid fusion was obtained in 18 cases, probable fusion in 4 cases, and nonunion in 4 cases, and the fusion rate was 84.61% in open group; solid fusion was obtained in 21 cases, probable fusion in 3 cases, and nonunion in 4 cases, and the fusion rate was 85.71% in minimally invasive group; and the interbody fusion rates showed no significant difference between 2 groups (χ2=0.072, P=0.821). ConclusionCompared with open TLIF, paramedian incision mini-TLIF has advantages of minimal surgical trauma and little blood loss for single-level lumbar degenerative disease. The short- and medium-term effectivenesses are satisfactory.
Objective To compare three surgical treatments for mediastinal mass with myasthenia gravis. Methods Retrospective analysis was performed on the clinical data of 53 patients who underwent extended thymectomy between January 2010 and December 2017 in our hospital. There were 29 males and 24 females, aged 17-73 years. Patients were divided into three groups according to the surgical methods: a group A (video-assisted thoracoscopic surgery with the da Vinci robotic system, n=22), a group B (video-assisted thoracoscopic surgery, n=12) and a group C (median sternotomy, n=19). The gender distribution, age, intraoperative blood loss, operation time, postoperative extubation time, postoperative hospital stay, Osserman classification of myasthenia gravis, postoperative myasthenic remission rate, etc were compared in three groups. Results No perioperative death was observed in 53 patients. One patient in the group C suffered from postoperative myasthenic crisis and improved after active treatment. One patient with video-assisted thoracoscopic surgery was converted to median sternotomy due to the intraoperative injury of the left brachiocephalic vein. Compared with the group B and group C, the group A had shorter operation time, less intraoperative blood loss and drainage on the first postoperative day and fewer days of extubation. Postoperative hospital stay was less in the group A than that in the group C (P<0.05). The postoperative myasthenic remission rate was higher in the group A than that in the other two groups, but there was no statistical difference. Conclusion Because of the robot’s unique minimally invasive advantage, in this study, the outcome of patients with myasthenia gravis treated with Da Vinci robots and thymectomy is better than that of the remaining two groups in terms of perioperative outcomes and myasthenic remission rate. But long-term results and a large of number matching experiments are needed to confirm. However, it is undeniable that robotic surgery must be the future of the minimally invasive surgery.
Objective To investigate the mid- to long-term follow-up results of ascending aorta (AAO)-descending thoracic aorta (DTA) bypass grafting via median sternotomy incision for the treatment of complex aortic arch coarctation. Methods A retrospective analysis was conducted on the clinical data of patients with complex aortic arch coarctation who underwent AAO-DTA bypass grafting via median sternotomy incision at the First Hospital of Tsinghua University from August 2004 to May 2017. ResultsA total of 7 patients were enrolled, including 4 males and 3 females, aged (13.3±4.6) years, and weighted (40.2±12.2) kg. Six (85.7%) patients had concomitant upper limb hypertension. Four patients were aortic arch coarctation combined with intracardiac malformations, two were post-operative restenosis, and 1 was post-operative restenosis combined with intracardiac malformation. All patients underwent surgery under cardiopulmonary bypass. There were no perioperative deaths or major complications. The pre-operative upper-lower limb pressure difference was (39.3±19.2) mm Hg, which decreased to (2.9±2.7) mm Hg post-operatively (P<0.01). The follow-up period was (14.9±5.9) years. There were no long-term deaths or artificial graft-related complications. Except for one patient who still had mild hypertension, the blood pressure of the remaining patients returned to normal. Conclusion AAO-DTA bypass grafting via median sternotomy incision for the treatment of complex aortic arch coarctation can effectively reduce upper limb blood pressure and the upper-lower limb arterial pressure difference, has fewer complications, and demonstrates satisfactory mid- to long-term efficacy.
ObjectiveTo investigate the effect of delayed sternal closure (DSC) on sternal wound debridement after pediatric cardiac surgery. MethodsWe retrospectively analyzed clinical data of 491 pediatric patients underwent DSC in Guangdong General Hospital between June 2009 and June 2014. There were 333 males and 158 females with age of 1 day to 153.37 (5.68±17.24) months. The rate of sternal wound debridement between the DSC patients and the non-DSC patients was compared. ResultsA total of 454 pediatric patients with DSC initiated in the operation room. And 37 patients with DSC initiated in intensive care unit after emergency sternotomy. A total of 392 patients with delayed sternal closure were discharged. Eight patients gave up treatment for family reasons and 91 patients died. Patients with DSC had higher incidence of sternal wound debridement than the patients with non-DSC did (χ2=6.693, P=0.010). ConclusionDSC is an effective treatment for children with severe cardiac surgery, while it causes higher incidence of sternal wound debridement.
ObjectiveTo analyze the clinical efficacy of right minithoracotomy approach in the treatment of patients with regurgitation after left-sided valve surgery (LSVS).MethodsThe clinical data of 77 patients who suffered tricuspid regurgitation (TR) after LSVS and received surgical treatment in the Heart Center of Henan Provincial People's Hospital from 2012 to 2019 were selected. According to the operation method, the patients were divided into a right minithoracotomy group (n=32), including 13 (40.6%) males, aged 57.3±5.3 years and a median sternotomy group (n=45), including 17 (37.8%) males, aged 55.7±6.6 years. Preoperative and postoperative clinical data of the two groups were compared and analyzed.ResultsThere was no significant difference in preoperative data between the two groups. There were 24 patients of tricuspid valvuloplasty (TVP) and 8 patients of tricuspid valve replacement (TVR) in the right minithoracotomy group. There were 29 patients of TVP and 16 patients of TVR in the median sternotomy group. The operation time, postoperative hospitalization time, intubation time and ICU stay time of the right minithoracotomy group were shorter than those of the median sternotomy group (P<0.001). The operative bleeding, postoperative drainage in 24 hours, postoperative blood transfusion rate and incision poor healing of the right minithoracotomy group were significantly decreased compared with those of the median sternotomy group (P<0.05). The extracorporeal circulation time between the two groups was not significantly different (P=0.382). The postoperative complications and mortality of the righ minithoracotomy group were significantly lower than those of the median sternotomy group (P<0.05).ConclusionThe procedure of right minithoracotomy access can reduce perioperative morbidity and mortality compared with the median sternotomy, and results in satisfied clinical efficacy.
Objective To investigate surgical strategies using bilateral pectoralis major muscle flaps for the treatment of sternal dehiscence after cardiac surgery. Methods From May 2005 to October 2010，21 patients with sternal dehiscence, sternal osteomyelitis and mediastinitis after cardiac surgery were admitted to Beijing An Zhen Hospital of Capital Medical University. There were 13 male patients and 8 female patients with their age of 53-72 （64.5±7.8） years. There were 19 patients after coronary artery bypass grafting （CABG） and 2 patients after heart valve replacement. The non-viable and necrotic bones were debrided and sternal wires partially or completely removed. The sternal origins of pectoralis major were released on both sides. The pectoralis major muscle flaps were tensionlessly sutured across medially over the sternal defect. Multiple suction drains were placed and removed in due time. The skin was intermittently closed. Results All the pectoralis major muscle flaps lived well after surgery，and all the patients were discharged in 2 weeks after surgery. Twenty patients were discharged with complete wound closure，and 1 patient had wound fistula and infection after removal of suction drains that was healed after another surgery to resect the wound fistula. During 6 month follow-up，sternal wound healed well in all the patients with normal thoracic appearance，and none of the patients had abnormal respiratory movement, infection recurrence or persistent infection. Conclusion Bilateral pectoralis major muscle flap technique is a positive and efficient surgical strategy for the treatment of refractory sternal dehiscence after cardiac surgery.
