Ultrasound estimation of volume of postoperative pleural effusion in cardiac surgery patients.
The aim of this study was to establish a practical simplified formula to facilitate the management of a frequently occurring postoperative complication, pleural effusion. Chest ultrasonography with better sensitivity and reliability in the diagnosis of pleural effusions than chest X-ray can be repeated serially at the bedside without any radiation risk. One hundred and fifty patients after cardiac surgery with basal pleural opacity on chest X-ray have been included in our prospective observational study during a two-year period. ⋯ The success rate of obtaining fluid was 100% without any complications. There is a high accuracy between the estimated and drained pleural effusion. Simple quantification of pleural effusion enables time and cost-effective decision-making for thoracentesis in postoperative patients.

ReviewVolume load paradox while preparing for the Fontan: not too much for the ventricle, not too little for the lungs.
Ventricular dysfunction is frequently encountered in Fontan patients. Cardiologists and cardiac surgeons have, therefore, mainly focused on preservation of cardiac function, limiting the early volume overload as much as possible both in magnitude and duration. ⋯ The volume requirements for optimal growth and development of the ventricle and the lungs are different and divergent. Avoiding overload of the ventricle is important, but excessive protection from volume overload may not be necessary and may result in PA hypoplasia, which in turn will severely affect the Fontan circuit.

ReviewIs pH-stat or alpha-stat the best technique to follow in patients undergoing deep hypothermic circulatory arrest?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether pH-stat or alpha-stat is the best technique to follow in patients undergoing deep hypothermic circulatory arrest. Altogether 206 papers were found using the reported search, of which 16 represent the best evidence to answer the clinical question. ⋯ Conversely, all seven papers that suggested alpha-stat method is associated with better intraoperative and postoperative outcome were based on studies done on adult patients. The remaining four papers suggested no significant difference between the pH-stat group and alpha-stat group. In conclusion, there is evidence to suggest that the best technique to follow in the management of acid-base in patients undergoing deep hypothermic circulatory arrest during cardiac surgery is dependent upon the age of the patient with better results using pH-stat in the paediatric patient and alpha-stat in the adult patient.

Case ReportsRepair of coronary artery perforation following angioplasty using TachoSil patches.
Coronary perforation is a rare complication of percutaneous interventional procedures, occurring in 0.2-3% of procedures, which may require emergency coronary bypass surgery. We describe here an alternative method to deal with such complication, which proved effective in a patient with active bleeding from the left anterior descending (LAD) coronary artery. By temporary pressing on beating heart patches of TachoSil, a sponge impregnated with human fibrinogen and thrombin, on the bleeding site, complete and stable hemostasis was achieved.

Osseous metastases of renal cell carcinoma (RCC) are the second most frequent location after lung metastases. They rarely present as isolated location. When isolated, resection may offer five-year survival rates of 30-60%. ⋯ The overall five and ten-year survival rates were respectively, 83 and 66.7%. IRM of RCC are rare and remain not well-known. Surgical wide resection is a safe and effective treatment.
