ABSTRACT
Objective To guide clinical operation,the invasion,efficacy,convalescence by different operating ways on cardiac surgery were studied.Methods Left axillary minithoracotomy was applied to 41 patients with ductus atteriosus(A group);right axillary minithoracotomy was applied to 46 patients with atrial soptal defect (ASD),ventricular septal dofect(VSD),triple-symptom complex of Fallot(C group);49 patients with replacement of valvular heart,VSD,ASD,totralogy of Fallot,left atrial myxoma were operated in substernal segment minithoracotomy (D group).The comparison between above groups and the regular left chest posterolateral operation on 42 patients (B group) and the sternal median operation on 77 patients (E group)was carried out.Results (1) A group had such advantages as the operation time,hemorrhage volume,hospital day,compared with B group [(38±13) min vs (64±14) min,(17±12) ml vs (200±100) ml,(6±2) d vs(11±3) d,respectively](P<0.01).(2) There were difference in extra corporeal circulation time,bemorrhage volume and hospital day between C group and E group[(39±8) min vs (68±8)min,(150±150) ml vs (700±300)ml,(8±3)d vs(12±4)d,respectively](P<0.01 or <0.05).There were difference in hemorrhage volume,fluence between D group and E group (P<0.05).Conclusion Small incision,slight trauma,less hemorrhage,slight ache,quick recovery,concealed incision and so on are characteristic of the left subaxillary minithoracotomy for ligation of ductus arteriosus,the right subexillary minithoracotomy for opening heart operation with heart beating and the substernal segment minithoracotomy for opening heart operation with extra corporeal circulation.
