    Background and Aim: Recent studies suggested that prothrombin complex concentrate (PCC) might be more effective than fresh frozen plasma (FFP) to reduce red blood cell (RBC) transfusion requirement after cardiac surgery. The benefits and risks associated with the use of PCC over FFP have been investigated in this study including patients undergoing isolated coronary artery bypass grafting(CABG) from a prospective, multicenter registry. Methods: This is a comparative analysis of 416 patients who received postoperatively FFP and 119 patients who received PCC with or without FFP after isolated CABG. Results: Mixed-effects regression analyses adjusted for multiple covariates and participating centers showed that PCC significantly decreased RBC transfusion (67.2% vs. 87.5%, adjusted OR 0.319, 95%CI 0.136-0.752) and platelet transfusion requirements (11.8% vs. 45.2%, adjusted OR 0.238, 95%CI 0.097-0.566) compared with FFP. The PCC cohort received a mean of 2.7\ub13.7 (median, 2.0, IQR 4) units of RBC and the FFP cohort received a mean of 4.9\ub16.3 (median, 3.0, IQR 4) units of RBC (adjusted coefficient, -1.926, 95%CI -3.357-0.494). The use of PCC increased the risk of KDIGO acute kidney injury (41.4% vs. 28.2%, adjusted OR 2.300, 1.203-4.400), but not of KDIGO acute kidney injury stage 3 (6.0% vs. 8.0%, OR 0.850, 95%CI 0.258-2.796) when compared with the FFP cohort. Conclusions: These results suggest that the use of PCC compared with FFP may reduce the need of blood transfusion after CABG. In view of the observational nature of this study, these results shoul

    Background and aim: The aim of this study was to evaluate the prognostic impact of asymptomatic carotid artery stenosis(CAS) in patients undergoing isolated coronary artery bypass grafting(CABG). Methods:Patients from the multicenter, prospective E-CABG registry without history of stroke or transient ischemic attack and screened by duplex ultrasound for CAS before isolated CABG were included in this analysis. Results:Among 2813 patients screened by duplex ultrasound for asymptomatic CAS, 11.1% had a CAS of 50-59%, 6.0% of 60-69%, 3.1% of 70-79%, 1.4% of 80-89%, 0.5% of 90-99%, and 1.1% had carotid occlusion. Postoperative stroke occurred in 25 patients(0.9%). Lesions were bilateral in five patients(25%) and ipsilateral to a CAS 6550% in six patients(30%). In univariate analysis, the severity of CAS was associated with a significantly increased risk of stroke(p<0.0001). In multivariate analysis, a CAS of 90-99%(OR 12.03, 95%CI 1.34-108.23) and the presence of an occluded internal carotid artery(OR 8.783, 95%CI 1.820-42.40) were independent predictors of stroke along with urgency of the procedure, severe-massive bleeding according to the E-CABG classification and the presence of a porcelain ascending aorta. Conclusions: Among patients with asymptomatic CAS, the risk of stroke is significant only in patients with a stenosis 6590%. Since this condition has a low prevalence and when left untreated is associated with a relatively low rate of stroke, preoperative screening of asymptomatic CAS before CABG may not be justified. Instead, avoiding manipulation of diseased ascending aorta and prevention of excessive bleeding may be more effective measures to prevent stroke after CABG

    Current trends in cannulation and neuroprotection during surgery of the aortic arch in Europe†‡

    OBJECTIVES To conduct a survey across European cardiac centres to evaluate the methods used for cerebral protection during aortic surgery involving the aortic arch. METHODS All European centres were contacted and surgeons were requested to fill out a short, comprehensive questionnaire on an internet-based platform. One-third of more than 400 contacted centres completed the survey correctly. RESULTS The most preferred site for arterial cannulation is the subclavian-axillary, both in acute and chronic presentation. The femoral artery is still frequently used in the acute condition, while the ascending aorta is a frequent second choice in the case of chronic presentation. Bilateral antegrade brain perfusion is chosen by the majority of centres (2/3 of cases), while retrograde perfusion or circulatory arrest is very seldom used and almost exclusively in acute clinical presentation. The same pumping system of the cardio pulmonary bypass is most of the time used for selective cerebral perfusion, and the perfusate temperature is usually maintained between 22 and 26°C. One-third of the centres use lower temperatures. Perfusate flow and pressure are fairly consistent among centres in the range of 10-15 ml/kg and 60 mmHg, respectively. In 60% of cases, barbiturates are added for cerebral protection, while visceral perfusion still receives little attention. Regarding cerebral monitoring, there is a general tendency to use near-infrared spectroscopy associated with bilateral radial pressure measurement. CONCLUSIONS These data represent a snapshot of the strategies used for cerebral protection during major aortic surgery in current practice, and may serve as a reference for standardization and refinement of different approache

    Sternal wound dehiscence from intense coughing in a cardiac surgery patient: could it be prevented?

    This case report is on a obese patient who underwent a coronary artery bypass. The immediate postoperative phase, on the 8th day, was characterized by sternal dehiscence with diastasis, from intense coughing. At present, for obese patients there are not any guidelines aimed to prevent the sternal diastasis. The use of a sternum support vest after median sternotomy could be a valuable tool in the postoperative care of our patients, in order to avoid chest wall hyperexpansion and to prevent sternal wound dehiscence and diastasis
