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.
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 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.
Objective To evaluate the preliminary the therapeutic effect of the aortic proximal anastomosis device applied in coronary artery bypass grafting (CABG), and further to assess its safety and feasibility. Methods From January 2006 to May 2007， 50 patients underwent CABG were received the aortic proximal anastomosis device ［Novare Enclose Ⅱ device (Novare Surgical System, Cupertino, CA)］, in which 16 were underwent in onpump CABG and 34 in offpump CABG(OPCAB). The age was 56.2±18.7years(from 55 to 80 years), and there were 38 males and 12 females. Preoperative complications included hypertension in 28 cases, diabetes in 17 cases, old myocardial infarction 18 cases and old cerebral infarction in 15 cases. A total of 175 proximal anastomoses were performed (3.2±1.3), among which there were 152 vein, 12 free left internal mammary artery (LIMA) and 11 radial artery anastomoses. Results Intraoperative transient graft flow meter revealed a satisfactory blood flow. There were no device related complications, and there was no hospital death. 2 cases needed chest re-exploration for hemostasis, 2 cases needed tracheostomy for respiratory insufficiency, and 1 case needed hematodialysis for renal inadequacy caused by diabetic nephropathy. All this 5 patients got recovered and discharged after active treatment. There were no cerebra related complications and no severe cardiac accidents. Follow-up 1 to 3 months after surgery via telephone or letter revealed a 100% survival rate and a 100% exemption rate of cardiac accident. Conclusion Preliminary clinical application of the Novare Enclose Ⅱ device is safe and efficient, but its middle and longterm effect remains to be further observed.
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 coronary artery bypass grafting (CABG) on patients with coronary heart disease and giant left ventricular dimension but without aneurysm. Methods The clinic data of 51 consecutive patients with coronary heart disease accompanied by enlarged left ventricle dimension without aneurysm, including 50 males and 1 female, undergoing CABG between January 2004 and December 2006 in Nanjing First Hospital of Nanjing Medical University was retrospectively reviewed. The patients were at the age of 54-61 years with an age of 57.5±3.2 years. All patients received CABG, combined with aortic valve replacement in 7, mitral valve replacement in 16, mitral valvoplasty in 17 and tricuspid valvoplasty in 7. After surgery, perioperative complications and mortality were closely observed and followup for a period of 37 months was carried out. Results The number of distal anastomoses per patient was 2.0-4.0(3.8±1.1). Four patients died perioperatively (7.8%), among whom 2 died from malignant ventricular fibrillation, 1 from acute kidney failure and 1 from stroke caused by severe low cardiac output syndrome. All other patients were discharged from hospital with good recovery. After operation, 5 patients had atrial fibrillation and 11 had ventricular fibrillation, but all of those patients survived after proper treatment. The followup period for 47 patients was 37-49 months (43±11months), with a followup rate of 100%. No death occurred during the follow-up. Ultrasound cardiography in the followup period showed that there was a decreased left ventricular enddiastolic dimension (59±2 mm vs. 68±5 mm; t=7.320, Plt;0.05) and an improved left ventricular ejection fraction (45%±17% vs. 34%±15%; t=4.770, Plt;0.05) compared with those before operation with statistical significance. Conclusion CABG is an effective surgical procedure in the treatment of coronary heart disease with giant left ventricular dimension but without aneurysm.
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.
ObjectiveTo discuss the effect of Cabrol in treatment of Stanford type A aortic dissection.MethodsThe clinical data of patients whom were diagnosed with type A aortic dissection of Stanford in our hospital from January 2013 to January 2018 were retrospectively analyzed. All of 40 patients underwent Cabrol surgical procedure. There were 31 males and 9 females aged 26–75 (48.8±3.3) years. The surgical treatment effect of the patients was evaluated, mainly including the aortic index, the changes in cardiac function before and after operation, and the postoperative follow-up.ResultsAll the 40 patients completed the operation successfully. The diameter of ascending aorta and aortic sinus in postoperative patients were smaller than those before operation (P<0.05). Postoperative left ventricular ejection fraction and cardiac output increased, central venous pressure and left ventricular end-diastolic dimension decreased, and cardiac function indexes were significantly different from those before the operation (P<0.05). Seven patients suffered complications in postoperative follow-up including one stenting leakage, three neurological diseases and three acute renal failure. Two patients died postoperatively.ConclusionCabrol’s operation is effective in the treatment of Stanford type A aortic dissection, which can significantly improve the cardiac function of patients, simplify the anastomosis of coronary artery ostia and decrease amount of bleeding.
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.
