\n\nMethods: The subjects were 102 patients undergoing emergency surgery for acute type A dissection from July 2005 to October 2010. They were divided into group I (n = 45) undergoing aortic surgery without tear resection and group II (n = 57) undergoing resection that included AR-13324 the intimal tear.\n\nResults: The postoperative hospital mortality was similar, 13.3% (n = 6) in group I and 12.3% (n = 7) in group II. Of the 102 patients, 69 underwent follow-up computed tomography scanning after discharge, and

the aortic diameter was significantly increased in group I compared with that in group II (P = .035). Dilatation of the descending aorta occurred in 21 patients (30.4%). Multivariate logistic regression analysis revealed that a patent false lumen (P = .027) and nonexclusion of the entry site (P = .012) were independent risk

factors for aortic dilatation. No difference was found in the LDC000067 freedom from aorta-related clinical events at 4 years, with a rate of 81.9% in group I and 74.4% in group II. Also, no difference was found in the 4-year actuarial survival rate between groups I and II (86.4% and 78.5%, respectively).\n\nConclusions: The prognosis of patients without exclusion of the entry site was acceptable. Careful follow-up is needed for patients with a patent false lumen or nonexcluded entry because of the risk of aortic dilatation.”
“BACKGROUND: Reversal of warfarin with plasma accounts for a large amount of fresh-frozen plasma transfused in the United States. The use of vitaminK is an alternate strategy. STUDY DESIGN AND METHODS: Records of vitaminK prescriptions for warfarin reversal were examined and recipients identified

where data were available on dosage, route of administration (oral [PO] and intravenous [IV]) and the availability of both pre- and postadministration international normalized ratio(s) (INRs). RESULTS: A total of 135 administration events were evaluated: 81 PO and 54 IV. The median (range) preadministration INRs were 5.8 (1.9-16.5) versus 5.0 (1.4-16.5; p=0.61) and the median (range) for the postadministration INRs were 2.4 (1.0-10.4) and 2.1 (1.2-8.2; selleck products p<0.01) for the PO and IV routes, respectively. The median (range) doses were 2.5(1-10) and 2.0(1-10) mg for PO and IV, respectively (p<0.01). A total of 44% of the IV vitaminK group achieved an INR of 2 or less within 12 hours versus 14% for the PO route (p<0.01). In multilinear regression the preadministration INR (r=0.14, p<0.01) and time after administration (r=0.05, p<0.01) were independent variables influencing the postadministration INR but the dose administered (r=0.09, p=0.07) was not. CONCLUSION: VitaminK needs to be given IV if urgent partial correction (<12hr) of warfarin is required. No influence of dose administered in the range 1 to 10mg on the postadministration INR was observed.”
