PURPOSE: Gastrointestinal complications (GICs) such as gastroduodenal ulcer, enterocolitis, and ischemic colitis after coronary artery bypass grafting (CABG) are rare, but are associated with high mortality and morbidity. The present study was performed to detect risk factors and to investigate outcomes following GICs after CABG. METHODS: Between January 1992 and December 2001, 17 of 549 patients (3.1%) developed GICs after CABG with cardiopulmonary bypass, presenting with gastrointestinal bleeding due to gastroduodenal ulcer, enterocolitis, or ischemic colitis. We conducted a retrospective analysis of these patients. RESULTS: All patients required emergent treatment for hemorrhage by means of blood transfusion and endoscopic ablation and/or clipping. The following possible predictors of GICs were identified by logistic multivariate analysis: age over 70, diabetes mellitus (particularly insulin-dependent diabetes), history of cerebrovascular disease or history of renal failure and postoperative low output syndrome (LOS). CONCLUSION: Our results suggested that GICs after CABG with cardiopulmonary bypass are rare but can be lethal. Early diagnosis and prompt intervention can be difficult but are potentially life saving for patients in whom GICs develop. 相似文献

OBJECTIVE: Complications occurring after coronary artery bypass graft (CABG) surgery, particularly neurologic damage, have been mainly correlated with the use of cardiopulmonary bypass (CPB). The aim of this work was to compare postoperative outcomes of patients undergoing CABG surgery, with or without the use of CPB, focusing on neurologic events. DESIGN: Observational study. SETTING: University tertiary care hospital. PARTICIPANTS: Two thousand seven hundred and forty consecutive patients who underwent CABG surgery in the period January 1998 to January 2003. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: For 738 patients, the operation was performed off-pump (OP group), and for 2002 patients CPB was used (CPB group). OP and CPB groups were compared with regard to preoperative status, anesthetic management, and postoperative outcomes, by means of univariate and multivariate analyses. Surgeons' propensity to operate off-pump was based on patients' age, renal conditions, and hemodynamics. Univariate and multivariate analyses showed that CPB was associated with a higher incidence of type I neurologic events compared with OP technique (2.1% versus 0.9%, odds ratio [OR]: 2.6, 95% confidence interval [CI], 1.2-5.9). A history of previous stroke (OR: 2.7, 95% CI, 1.2-5.9) and advanced age (OR: 1.06 per year, 95% CI, 1.02-1.09) were additional independent predictors of postoperative type I neurologic events. CONCLUSIONS: In the authors' experience, off-pump CABG surgery offers some benefits compared with CPB in respect to major neurologic complications. 相似文献

In the preoperative care of patients for coronary artery bypass grafting, emphasis is given to the need for good coronary arteriograms and left ventricular cineangiograms, and the proper timing of operation after these investigations. The special measures needed for dealing with unstable and variant angina are discussed, and it is recommended that betaadrenergic blocking drugs should not be discontinued before operation.
Good postoperative care is easiest when the operation habeen correctly performed. The management of postoperative hypertension, arrhythmias, low output syndrome, and myocardial infarction is discussed. Following discharge from the hospital, it is important to minimize known risk indicators for coronary artery disease and to encourage the patient to achieve as complete functional rehabilitation as possible. Excellent relief of angina is obtained in about 80% of patients initially, but in those who have recurrence of chest pain postoperatively, the possibility of a second coronary artery bypass grafting operation may be considered. The need for long-term follow-up and aftercare of coronary artery surgical patients is stressed, so that the true benefit to the patient in terms of improved quality and quantity of life may be established.

Résumé Dans la préparation préopératoire en vue d'un pontage coronaire, il est important d'avoir de bonnes coronarographies et une bonne ventriculographie gauche et il faut, entre ces examens et l'opération, un délai adéquat. Nous discutons les mesures spéciales à prendre en cas d'angor instable et variable. Il ne faut pas arrêter les drogues bêta-bloquantes avant l'intervention.Les soins postopératoires sont faciles lorsque l'opération a été bien faite. Nous discutons les thérapeutiques de l'hypertension postopératoire, des arythmies, des débits bas, d l'infarctus myocardique. Après la sortie de l'hôpital, le malade doit éviter tous les facteurs favorisant la maladie coronaire et il faut encourager une réhabilitation fonctionnelle aussi complète que possible. On atteint, au début, une sédation excellente de l'angor dans quelques 80% des cas. Chez ceux qui ont, après l'opération, une récidive de douleurs thoraciques, il faut envisager la possibilité d'un second pontage coronarien. Les opérés des coronaires doivent être suivis et traités pendant longtemps, pour que l'on puisse préciser le réel gain pour les malades aux points de vue durée et qualité de la survie.

The presence of occlusive disease of the subclavian artery (SCA) proximal to the origin of the internal thoracic artery (ITA) influences the operative strategy and the outcome of coronary artery bypass grafting (CABG). Of 780 patients who underwent CABG, concomitant SCA occlusive lesions were reconstructed in 13 patients (nine males, four females). The affected SCAs were left-sided in 11 patients, and right-sided and bilateral in one, each. An aortoaxillary bypass utilizing an 8-mm PTFE graft was constructed in nine patients and a carotid-subclavian (C-S) transposition in two, simultaneously with CABG. Percutaneous balloon angioplasty with a stent was performed in two patients prior to CABG. With follow-up periods ranging from 4 to 8.4 years (mean, 6.3 years), aortoaxillary bypass grafts were patent in all patients. Other reconstructive procedures, including a C-S transposition and balloon angioplasty, were performed safely and effectively in off-pump CABG patients. In six patients, the left internal thoracic artery (LITA) could be used as a graft to the coronary artery after SCA reconstruction. Aortoaxillary bypass using an 8-mm PTFE graft is a safe and effective way for simultaneous subclavian reconstruction in patients undergoing CABG. Mid-term patency of the graft is satisfactory. The LITA can be used as a graft to the coronary arteries in selected patients. Preoperative brachial angiography is mandatory in these patients. 相似文献

OBJECTIVES: Blood conservation remains an important issue for patients undergoing cardiac surgery with cardiopulmonary bypass. Platelet sequestration (PSQ) is an aggressive autologous blood conservation method, whose effectiveness is still debated. The main objective of the present study was to evaluate whether PSQ reduces postoperative blood transfusion requirements in patients undergoing coronary artery bypass grafting (CABG) and to determine if PSQ is a cost-effective blood conservation method. MATERIAL AND METHODS: All adult patients admitted for CABG entered the study. Exclusion criteria were: recent blood transfusion (<7 days), a platelet count of 150x10(3)/microl or less, hematocrit less than 35% and body weight 50 kg or less. The sequestration was aim 20% or more of the total platelet plasma volume. The sequestration protocol was three sequestration cycles performed just prior to surgery. The concentrated platelet portion was reinfused after weaning from the cardiopulmonary bypass. Hundred seven parameters/patients were recorded. Sixty patients entered the study; 30 in the PSQ group and 30 controls (CTR). RESULTS: Patient characteristics, operation data, preoperative hematology and coagulation parameters did not differ between the groups. In the PSQ group a mean of 433+/-34 ml concentrated platelet portion was collected. The mean platelet count in the concentrated platelet portion was 749+/-157x10(3)/microl, resulting in a platelet yield of 28+/-6% (2040%). The average total chest tube blood loss was 423 ml (PSQ) compared to 858 ml (CTR), p<0.001. A greater number of CTR patients required blood transfusion postoperatively (23) compared to PSQ (3), P<0.001, and fluid requirements were also significantly increased in the control group, P<0.001. No statistical differences in hematology and coagulation parameters between the groups were observed. The hospital mortality was low and the incidence of postoperative complications was few and without group differences. Post-extubation gas exchange was better in PSQ patients compared to CTR. CONCLUSIONS: A preoperative PSQ of a minimum 20% of the total platelet plasma volume resulted in significantly lower postoperative blood loss and fluid and blood transfusion requirements compared to controls. Post-extubation gas exchange was also better after PSQ. Only one patient did not tolerate the sequestration. No other adverse effects of the procedure were observed. 相似文献
