  • Skeletonized bilateral internal mammary artery harvesting with harmonic scalpel in coronary artery bypass grafting

    ObjectiveTo summarize the use of harmonic scalpel to harvest bilateral internal mammary artery in coronary artery bypass grafting (CABG). MethodsThe clinical data of 54 patients of bilateral skeletonized internal mammary artery harvesting for CABG in our hospital from January 2016 to May 2020 were analyzed retrospectively. There were 51 males and 3 females with a mean age of 62.37±9.56 years. ResultsAll patients went through the procedure unevently and discharged from hospital. The number of grafts was 4.07±0.85 per patient, the operation time was 267.21±47.00 min, mechanical ventilation time was 342.43±132.17 min and hospital stay was 12.21±4.43 d. ConclusionIt is safe and effective to use harmonic scalpel to harvest skeletonized bilateral internal mammary artery in CABG.

  • Perioperative Outcomes of Coronary Artery Bypass Grafting Using the Radial Artery

    Objective To explore perioperative outcomes of coronary artery bypass grafting (CABG) using the radialartery as the second arterial graft. Methods Clinical data of 175 consecutive patients undergoing off-pump coronary artery bypass grafting (OPCAB) in General Hospital of Shenyang Military Command from August 2011 to April 2012 were retrospectively analyzed. All the 175 patients were divided into two groups. There were 75 patients including 49 male and 26 female patients with their age of 56.8±8.2 years in group 1,who received radial artery as a graft vessel. There were 100patients including 66 male and 34 female patients with their age of 57.7±8.1 years in group 2,who received great saphenousvein but not radial artery as the graft vessel. The use of left internal mammary artery as a graft vessel was 100% in both groups. Perioperative cardiovascular events and other clinical results were compared between the two groups. Results All the patients survived OPCAB and there was no 30-day death. There was no statistical difference in operation time,thoracic drainage within the first 24 hours after surgery or postoperative hospital stay between the two groups(P>0.05). Length of postoperative ICU stay and mechanical ventilation time of group 1 were shorter than those of group 2,although the differencewas not statistically significant. The percentage of patients receiving prolonged postoperative inotropic therapy of group 2 was higher than that of group 1 [16% (16/100) vs. 12% (9/75)],although the difference was not statistically significant. Postoperatively,there was no patient in group 1 who had new-onset myocardial ischemia or received intra-aortic balloon pump (IABP) support for hemodynamic instability. In group 2,3 patients had new-onset myocardial ischemia and 2 patientsreceived IABP support after OPCAB. Conclusion Radial artery can partly replace great saphenous vein as a graft vesselfor OPCAB,which does not increase the risk of perioperative cardiovascular events but is beneficial for postoperativerecovery to some degree. Radial artery can be more extensively used in CABG.

  • Clinical Characteristics of Patients with Coronary Artery Disease Undergoing Isolated Aortic Valve Replacement

      Abstract:Objective To investigate clinical characteristics of patients with aortic valve disease and coronary artery disease (CAD), and improve the pertinence of clinical management. Methods Clinical data of 78 patients who were older than 50 years and underwent isolated aortic valve replacement (AVR) in General Hospital of Shenyang Command from January to October 2010. All the patients were divided into two groups according to whether they had CAD:20 patients with CAD in the CAD group, including 19 males and 1 female with their average age of 64.6±8.3 years, and 58 patients without  CAD in the control group, including 28 males and 30 females with their average age of 58.7±6.2 years. Clinical characteristics of AVR patients with CAD were analyzed by one-way analysis of variance and multiple factor analysis. Results  One-way analysis showed that the incidence of old age (P=0.000), male patients (P=0.004), diabetes (P=0.004), aortic regurgitation (P=0.034), valvular lesion (P=0.028), and postoperative mechanical ventilation time (P=0.008)of CAD group patients were significantly higher or longer than those of control group patients. Multiple factor analysis showed that independent clinical characteristics of AVR patients with CAD included male patients, old age, prolonged postoperative mechanical ventilation time, significantly decreased pulmonary arterial systolic pressure (PASP) at 6th postoperative month, and significant preoperative right ventricular diastolic dysfunction. Conclusion The screening age for possible CAD should be reasonably lowered if male patients with aortic valve disease have concomitant preoperative right ventricular  diastolic dysfunction and/or tricuspid aortic valve degeneration. Patients undergoing isolated AVR need to take medications to reverse left ventricular remodeling for a long time to avoid severe arrhythmia.
