Objective: To assess the applicability of the European Risk Score System in Cardiac Operations (EuroSCORE) in patients undergoing myocardial revascularization at the Heart Institute of Pernambuco.Method: From 2003 to 2004, 759 patients underwent myocardial revascularization. For the study, seven were excluded due to the lack of information on one aspect or another involved in obtaining the EuroSCORE. In order to assess the applicability of the EuroSCORE, an adjustment was made using a logistic regression model of operative mortality (response variable) on the EuroSCORE (explanatory variable). The calibration of the model was measured by comparing the morbidity observed with that expected, using the Hosmer-Lemeshow Test of Goodness of Fit. The accuracy of the model was evaluated by means of Statistics-c.Results: The accuracy of the model, estimated at 69.9%, and the calibration (Hosmer-Lemeshow test, p=0.663) were satisfactory. The total predicted mortality was practically identical to the observed -1.7%. The low-risk group (EuroSCORE: 0-2) comprised 231 patients and had two (0.87%) deaths within this group. The medium-risk group (EuroSCORE: 3-5) comprised 268 patients and one (0.37%) death occurred. The high-risk group (EuroSCORE: =6) comprised 253 patients and ten (3.95%) deaths occurred. The discrepancies between the percentages of deaths observed in these groups and those predicted by the model were not statistically significant on the basis of the result of the chisquare test (p=0.624).Conclusion: The EuroSCORE, a simple and objective index, proved to be a satisfactory predictor of operative mortality in patients submitted to myocardial revascularization in the Heart Institute of Pernambuco.

Hemangioma is a benign, noninvasive and non-metastatic neoplasm originating from endothelial cells of the blood vessels. The involvement of the urinary vesicle with neoplasias occurs in less than 0.5% of dogs. The main clinical signs are hematuria, dysuria, pollakiuria, incontinence and urinary obstruction. The diagnosis is based on imaging tests and is confirmed by histopathological examination. The treatment of choice is surgical resection with safety margins. This paper reports the case of a twelve-year-old Poodle with a history of abdominal pain, which was attended at the Florianópolis Veterinary Hospital. Abdominal ultrasound showed the presence of free fluid. During exploratory laparotomy, the urinary vesicle was observed to be ruptured, presenting a thickened wall and small areas of necrosis. A sample was sent for histopathological analysis and the diagnosis was of benign vascular neoplasia compatible with hemangioma.
