Objective To summarize and analyze the clinical experience and surgical results of re-do coronary artery bypass grafting (Re-CABG) for reconvert coronary artery disease. Methods Eighteen patients who underwent Re-CABG in this hospital between June 2001 and December 2006 were analyzed. There were 15 males and 3 females aged from 65 to 78 years old. Seven patients were in class III angina(CCS) and 11 patients were in class IV. Coronary artery angiography showed stenosis or occlusion of great saphenous vein grafts in 16 patients, occlusion of left internal mammary artery(LIMA) grafts in 2 patients and new significant stenosis of the native coronary artery in 6 patients. All Re-CABG were done through re-sternotomy. Fifteen patients underwent cardiopulmonary bypass (CPB for their Re-CABG and 3 patients underwent off-pump Re-CABG. The concomitant procedures included left ventricular aneurysmectomy in 1 patient, mitral valve repair in 3 patients, combined aortic and mitral valve replacement and carotid endarterectomy in 1 patient. Bilateral IMA were used in 4 patients, LIMA in 12 patients, radial artery in 3 patients, and the rest of the grafts consisted of great and lesser saphenous vein. Results In on-pump Re-CABG, the aortic cross clamp time was 57±26min (range 45 to 112 min), the CPB time was 78±24min (range 66 to 140 min).The mean number of distal anastomosis per patient was 3.11(range 1 to 5). Intraoperative flow study of the grafts by Medi-Stim Butterfly showed a mean flow rate of 27.0±12.5 ml/min with pulsatility index( PI)less than 4.2. Intra-aortic balloon pump (IABP) was used in 1 patient who underwent concomitant aortic and mitral valve replacement and carotid endarterectomy. Post-operatively this patient developed renal failure and expired 6 days later. There was no residual angina and peri-operative myocardial infarction in the remain 17 patients.The post-operatively mechanical ventilation time varied from 5 to 15 hours, chest drainage varied from 290 to 1 040ml. Seventeen patients were discharged uneventfully. Follow-up from 6 months to 4.5years in 17 patients showed no evidence of recurrent angina. Postoperative coronary artery angiography in 4 patients showed patent grafts. Conclusion Re-CABG can be performed as safely and effectively as primary CABG in spite of the fact that it is more demanding. Selecting the proper target vessels, satisfactory blood flow of grafts, complete revascularization and proper peri-operative management are all key factors to a successful Re-CABG.
Objective To summarize the early outcomes and clinic al experience of off-pump coronary artery bypass grafting (off-pump CABG) afte r off-pump coronary endarterectomy (CE) for patients with diffused coronary art ery disease. Methods From May 2003 to November 2006，83 patients with diffu sed coronary artery disease underwent CE without cardiopulmonary bypass and off-pump CABG. There were 61 males and 22 females with age ranged from 55 to 80 ye ars (65±7 years). There were 7 patients in Canadian Cardiac Society(CCS) an gina classⅡ,20 patients in class Ⅲ,and 56 patients in class Ⅳ. 36(43.4%) pat ients had history of myocardial infarction. Coronary angiogram revealed th at 5 patients had double vessels disease, and other 78 patients had triple ves s els disease with 16 left main stem disease. The left ventricular ejection fract ion(LVEF) ranged from 25% to 65% (51%±16%). One hundred and ten endarter e ctomies were performed in 83 patients totally which included 67 in left anterior descending artery(LAD)，9 in circumflex artery and 34 in right coronary artery . Twenty patients received onlay venous patch after CE in LAD and then grafte d by internal mammary artery (IMA) on the patch. There were 83 left IMA, 2 radia l arteries, others were great saphenous veins, the mean number of grafts was 3.9 ±1.2. Results There was no death in all patients. Intraoper ative graft flowmeter was used to check the flow in the grafts before chest cl osure. One hundred and one (92%) out of 110 grafts after CE showed a satisfactor y grafts flow(22±16ml/min) intraoperatively. Four patients had perioperative myocardial infarctions but none had hemodynamic changes. All patients discharged uneventfully. Seventyfive patients (90.4%) had 8 to 50 months followup with no angi na reoccurrence. Eight patients had coronary angiogram from 3 to 29 months af ter operation with all patent grafts to the CE coronaries. Conclusion Off-pump CABG with coronary endarterectomy is feasible and achieves surgical revascularization in patients with diffuse cor onary artery disease.
Objective To investigate the effect of combined carotid endarterectomy (CEA) and offpump coronary artery bypass grafting (OPCAB) on patients with carotid arteriostenosis and coronary heart diseases. Methods A total of 121 consecutive patients with carotid arteriostenosis and coronary artery diseases underwent CEA and OPCAB between January 2003 and December 2009 in Nanjing First Hospital of Nanjing Medical University. There were 81 males and 40 females, with their ages ranged from 62 to 72 years (67.2±4.5 years). All patients had 3vessel coronary artery lesions, and there were 3 cases of left main coronary artery lesion. Unilateral carotid arteriostenosis (≥50%) occurred in 95 patients, and bilateral (≥50%) in 26 patients. The occurrence of stroke, myocardial infarction, angina pectoris and other complications after operation was observed, and followup was carried out. Results All patients underwent unilateral CEA including 50 on the right side and 71 left. The mean block time of carotid artery in CEA was 20.5±7.0 minutes. The average number of distal grafts per patient in OPCAB was 2.9±0.3. None of the patients had stroke or myocardial infarction and no perioperative death occurred. Eightyseven patients felt well in terms of their neuropsycho symptoms; 32 felt no change; and 2 worsened. Follow-up was done for all the patients with a follow-up rate of 100%. The mean time of the follow-up was 67.5±12.5 months. During this period, none of the patients manifested stroke, myocardial infarction or neuropsycho symptoms. Conclusion Concomitant OPCAB and CEA is a safe and effective procedure in patients with carotid arteriostenosis and coronary artery diseases. It can reduce the rate of postoperative stroke significantly. However, longterm outcome of the procedure needs operative experience accumulation, longterm follow-up and observation, and serious research and illumination.
Abstract:Objective To investigate the reoperation indication,surgical timing and the key point of surgical treatment of prosthetic valve endocarditis （PVE） after valve replacement. Methods From February 2000 to July 2005,18 patients with PVE underwent surgery ,their clinical manifestation ,process of treatment and their prognosis outcome were analyzed. Results There were 3 patients （16.7 %） of early-death, 1 patient died of septic shock, and 2 patients died of multiple organ failure. Since 2003,there was no operative death for all 11 patients. There were 6 patients with respiratory insufficiency, 2 patients with renal insufficiency,which were recovered after treatment. The 15 survivors were followed up from 1 month to 5years. There was recurrence of infection in 1 patient who died after ineffective medical treatment. The other 14 patients recovered well. Conclusion It has high risk and high mortality for reoperation for PVE. Accurate reoperative indication,optimal surgical timing,radical debridment of infected tissue and correct perioperative use of antibiotics are the key factors to improve the reoperative result for PVE.
Objective To summarize experience in surgery about off-pump coronary artery bypass grafting(OPCAB)for the treatment of left main with three-vessel coronary disease. Methods OPCAB were perfomed in 33 patients of left main with three-vessel coronary disease. The left internal mammary artery(LIMA) was used to be the graft vessel to anastomose with left anterior descending. The saphenous vein was used to be the graft vessel to anastomose with left circumflex coronary artery, right coronary artery/posterior descend artery, diagonal branch, obtuse marginal branch. Results There was no operative death.The average number of grafting was 3.4 per case.There was no perioperative myocardial infarction, respiratory or hepatic or renal failure and other serious complications.Blood transfusion was not needed in 33% of cases.The angina pectoris was free after operation in all cases. Conclusions OPCAB is safe and effective for the treatment of left main with three-vessel coronary disease. The injuries were minimal. Preoperative preparation, using of intra-aortic balloon counterpulsation, operative matching, techniques and to create a skill and swift team for meet an emergency are the key factors to assure surgical outcome.

Methods Thirteen children aged 3 to 11 years old with severe or moderate hemophilia A were included in the present study from November 2008 to April 2009. For children in the treatment group, they were treated with low-dose short-course infusion of recombinant human factor Ⅷ concentration with a dose of 7.5-10.0 U/kg twice weekly as secondary prophylaxis for two months. The incidence of joint bleeding 2 months before treatment (control group) and during the 2 months of treatment (treatment group) was observed. Moreover, the incidence of their target joint bleeding was measured in both groups. Results Children in the control group had (3.77±2.13) joint bleedings while children in the treatment group had (0.46±0.87) joint bleedings, which was obviously lower than those in the control group (Plt;0.01). Meanwhile, the incidence of target joint bleeding in the treatment group was 0%, which was obviously lower than that in the control group (35.7%) (Plt;0.01). In the treatment group, the costs of treatment were about RMB 510-680 yuan/kg every 2 months. Conclusions Treatment with low-dose short-course infusion of recombinant human factor Ⅷ concentration can effectively decrease joint bleeding in children with severe and moderate hemophilia A, and can effectively decrease the incidence of target joint bleeding. Therefore, this method may play an important role in protection of the joint function in those patients at an acceptable cost.
ObjectiveTo explore the effect of continuous nursing on lung transplant patients at home based on humanistic care. MethodsAccording to hospitalization order, patients who received lung transplantation in our hospital from January 2016 to October 2020 were divided into a control group and a nursing group. The control group was treated with routine lung transplantation education and regular follow-up after discharge, and the nursing group received humanistic care during follow-up, health education at discharge, cultural exchange activities, and home care plans. After discharge, the self-management ability at home, medication adherence and satisfaction of home care between the two groups were campared. ResultsA total of 60 patients were included in the study. There were 23 patients in the control group, including 16 males and 7 females, with an average age of 58.70±11.00 years. There were 37 pateints in the nursing group, including 25 males and 12 females, with an average age of 57.90±13.20 years. The scores of self-management ability at home of the nursing group (self-concept 27.41±2.37 points vs. 21.78±3.54 points; self-care responsibility 20.73±1.63 points vs. 16.83±2.79 points; self-care skills 41.46±3.77 points vs. 28.26±4.11 points; health knowledge level 57.95±4.10 points vs. 44.87±5.79 points) were higher than those in the control group (all P＜0.05). The medication adherence (7.47±0.46 points vs. 6.87±0.28 points) and satisfaction of home care (23.80±1.20 points vs. 20.50±1.90 points) in the nursing group were higher than those in the control group (both P<0.05). ConclusionContinuous nursing based on humanistic care for lung transplant patients can effectively improve the self-management ability, medication adherence and nursing satisfaction of patients after discharge.
Objective To retrospectively review the clinical experience and early surgical results of combined cardiac valve surgery and coronary artery bypass grafting （CABG）. Methods From Jan. 2000 to Dec. 2005, combined valve surgery and CABG was performed in 81 patients. 37 patients were rheumatic heart disease with coronary stenosis, and 44 patients were coronary artery disease with valvular dysfunction. Single vessel disease was in 18 patients, two vessels disease in 9 and triple-vessel disease in 54. All the patients received sternotomy and combined valve surgery and CABG under cardiopulmonary bypass. Mitral valve repair and CABG were done in 26 patients. Valve replacement and CABG were done in 55 patients with 49 mechanical valves and 16 tissue valves. Four patients had left ventricular aneurysm resection concomitantly. The number of distal anastomosis was 3.12 5= 1.51 with 66 left internal mammary arteries bypassed to left anterior descending. Post-operative intra-aortic balloon pump was required in 4 cases for low cardiac output syndrome. Results Two patients died of low cardiac output syndrome with multiple organs failure. 79 patients had smooth recovery and discharged from hospital with improved heart function. 64 patients had completed follow-up with 5 late non cardiac related death in a mean follow-up period of 14.2 months. Conclusion Combined one stage valve surgery and CABG is effective with acceptable morbidity and mortality.
