Chinese Journal of Minimally Invasive Surgery 2001;0(06):-
Objective To discuss the clinical application and features of coronary artery bypass grafting(CABG) through left intercostal thoracotomy approach. Methods A total of 36 cases of CABG were performed through left intercostal thoracotomy approach from September 1996 to August 2005 in this hospital.The patients fell into four categories: ①single vessel disease in the left anterior descending artery(LAD);②re-operation of CABG with a patent LIMA(left internal mammary artery)-LAD bypass;③severe calcified ascending aorta;and ④concurrent other procedures that required left thoracotomy.There were 26 cases of single vessel disease,3 cases of double vessel disease,and 7 cases of triple vessel disease.Five cases had a history of percutaneous coronary interventions(PCIs) and 6 cases had a history of CABGs.The left ventricular ejection fraction was 0.562?0.107. Results Off pump CABG with 1~4 distal anastomosis was successfully accomplished in all the 36 cases,with an operation time of 190.4?44.1 min.Concurrent procedures included 2 cases of transmyocardial laser revascularization(TMLR),1 case of lung cancer resection,and 1 case of esophageal cancer resection.There was no in-hospital mortality.Two fatal cases were seen in long-term follow-up observations.Recurrent angina developed in 2 cases 1 year after operation,and was cured with a PCI in 1 case and with a re-operation of CABG in 1 case. Conclusions The left intercostal thoracotomy is a safe and feasible approach for CABG surgery in patients with some special types of coronary heart disease.The procedure can be performed under beating heart.

Objective: To summarize and analyze the early outcomes and clinical experience in 1198 patients undergone off-pump coronary artery bypass (OPCAB). Methods: This multi-center report covers 15 different institutes in China from October 1996 to May 2002. The ratio of OPCAB to conventional coronary artery bypass grafting (cCABG) was 85.2%. The mean age was (61.6?9.0) years. 77.3% patients were male and 22.7% were female. There were 34.6% patients with myocardial infarction, 58.2% with unstable angina pectoris, 18.7% with left main lesion, 76.9% with triple-vessel disease, 1.5% was redo surgery, and 9.9% emergent or urgent surgery. The mean left ventricular ejection fraction was 0.56?0.17. Results: The number of distal anastomosis was 3.1?0.9. IMA was used in 65.6% patients and radial artery was used in 18.0%. 13.5% OPCAB was combined with TMLR. IABP was used in 5.2% patients. The hospital mortality was 1.2%. The morbidity included 0.4% peri-operative myocardial infarction, 0.3% heart failure, 1.2% fatal arrhythmia, 2.0% pulmonary complications, 1.2% neurotic disorder, 0.7% renal dysfunction, 1.0% reopen for bleeding, and 0.6% delayed wound healing. Conclusion: OPCAB surgery is a safe and feasible procedure with good early results. Its late outcomes need further follow-up. OPCAB requires certain special skills and methods in practice so a specific training course should be designed.

OBJCETIVETo investigate the method of separation of culture of bone microvascular endothelial cells (BMECs) of human femoral head in vitro.
METHODSFrom October 2013 to January 2014,15 femoral heads without pathologic change from patients resected during hip replacement were selected involving 2 males and 13 females with a mean age of 71.2 years old ranging from 38 to 92. Cancellous bone in femoral head was bited into broken bone grain and transfered into medium in aseptic contidion. Cells were isolated by the methods of enzymic digestion and density gradient centrifugation,purified by differiential attachment. The characteristics of cells was observed by inverted microscope. vWF and CD31 immunofluorescence analysis was applied for identification of cells.
RESULTSThe number of cells was positively correlated with patients' age after 24 hours in primary culture. The older patients had the less cells numbered. After 4 to 5 days' culture, primary cells appeared short spindle,polygon shaped and cobblestone-like morphology. After 7 to 10 days' culture, primary cells proliferated densely, became fusion, arranged in swirl, and contact inhibition appeared significantly. Immunofluorescence staining revealed the cells were 100% positive for vWF and CD31, and it showed that the cultured cells were BMECs.
CONCLUSIONIt was a simple, steady, effective method with good reproducibility, by which highly purified human BMECs can be obtained.
