| Objective:To compare the results of right chest minimally invasive surgery with conventional median sternotomy incision to treat mitral valve disease,and to explore the advantages and indications of the minimally invasive procedure.Methods:41cases of mitral valve disease who accepted urgical treatment in our hospital from February2012to April2012were divided into two groups-right chest minimal-incision group (minimally invasive group)21cases; conventional median sternotomy incision group (control group)20cases.All performed mitral valve replacement or plasty with the help of cardiopulmonary bypass. Observe and record the establishing time of CPB (from thoracotomy to CPB start), CPB lasting time (from CPB start to stop), aortic cross-clamping time, operative duration, postoperative mechanical ventilation time, ICU observing time, postoperative drainage, length of stay in hospital, postoperative heart and lung function recovery(postoperative color Doppler ultrasound, NT-proBNP, arterial blood gas analysis, etc.),degree of pain and other indicators to compare.Results:Both the two procedures can obtain good effect, no perioperative deaths presenced, low cardiac output syndrome, respiratory and central nervous system complications did not appear, All patients’ wounds were I/A healing. Minimally invasive group has obvious advantages in the speed of recovery of the postoperative cardiac function, postoperative mechanical ventilation time, ICU observing time, postoperative drainage, postoperative pain and patient satisfaction (P<0.05). The differences of two groups of surgery in establishing time of CPB, CPB lasting time, aortic cross-clamping time, total surgery time, was not statistically significant (P>0.05).Conclusion:Compared with the conventional median sternotomy incision technique, the right chest minimal-incision surgical treatment to mitral valve disease has safe, beautiful, less blood loss, trauma recovery speed and other obvious advantages. |
