Using cone and plate(let) analyzer to predict bleeding in cardiac surgery.
The cone and plate(let) analyzer is an established method for assessing platelet function. It evaluates adherence of platelets on an extracellular matrix, expressed as a percentage of surface coverage and the average size of the aggregates. The purpose of this study was to determine the applicability of the cone and plate(let) analyzer in monitoring platelet function and predicting postoperative bleeding. ⋯ Patients with an aggregate average size < 20 microm(2) had a significantly higher incidence of severe bleeding (> 965 mL) than those with a size > 20 microm(2) (44% vs. 0%), and a higher mean blood loss (908 +/- 322 mL vs. 337 +/- 78 mL). Similar results were obtained for surface coverage < 5%, indicating the predictive value of these parameters. Preoperative platelet function as evaluated by the cone and plate(let) analyzer is an independent risk factor determining postoperative bleeding.

Case ReportsGiant bronchogenic cyst mimicking tension pneumothorax.
An 18-month-old girl presented with high fever and vomiting. Pneumothorax and a cystic formation in the right hemithorax were found on a chest radiograph. The cyst measuring 10 x 10 x 8 cm was resected by a simple wedge resection. Histology revealed a complicated bronchogenic cyst with abscess formation.

Case ReportsVasodilator resistant lethal spasm after uncomplicated off-pump coronary surgery.
We report a case of lethal spasm of non-grafted coronary arteries after an uncomplicated off-pump coronary artery bypass grafting in a patient with no predisposing factors other than smoking. Transcatheter intraluminal injection of several vasodilators failed to relieve the spasm. The patient remained in profound cardiogenic shock due to broad acute myocardial infarction and died of multiple organ failure.

Case ReportsMitral-aortic intervalvular pseudoaneurysm with ventricular septal defect.
A 35-year-old woman was found on echocardiography to have a pseudoaneurysm of the mitral-aortic intervalvular fibrosa, residual ventricular septal defect, and aortic regurgitation. She had undergone surgical closure of a ventricular septal defect at age 7 and was found to have residual shunt several years later. She had been followed nonsurgically and had symptoms of cardiac failure during her 2 pregnancies. The pseudoaneurysm and the septal defect were successfully repaired.
