Twenty-four neonatal pigs were exposed to periods of circulatory arrest of between 70 and 120 min under profound hypothermia at 15 degrees C. Brain tissue taken 6h after cardiopulmonary bypass was examined histologically and by electron microscopy for evidence of hypoxic damage. Specimens from control pigs and animals subjected to 70 min arrest showed no(More)
Five groups of neonatal pigs were subjected to cardiopulmonary bypass with circulatory arrest periods that varied from 70 to 120 minutes for the investigation of brain changes in induced deep-core hypothermia (15 degrees C) with circulatory arrest. The parameters that were analyzed were (1) microscopy of the brain in animals at 6 hours after bypass(More)
BACKGROUND Hemangiopericytoma is a rare mesenchymal neoplasm, accounting for about 1% of vascular tumors The tumor occurs most commonly in the skin, subcutaneous soft tissues, muscles of the extremities, retroperitoneum but rarely in the lung, trachea or mediastinum. CASE PRESENTATION A rare case of primary mediastinal hemangiopericytoma is presented. A(More)
Lung injury produced by cardiopulmonary bypass (CPB) is clinically characterized as postperfusion pulmonary dysfunction syndrome. The roles of humoral factors, altered perfusion modes and the occurrence of diffuse microembolism have been subjects of a number of studies. This paper presents the effectiveness of a platelet inhibiting drug, PGI2 in preventing(More)
AIM We examined the impact of leukocyte filtration during the entire bypass time on postoperative leukocytosis, perioperative hemorrhage and overall clinical outcome in patients undergoing elective cardiac surgery. METHODS Eighty patients who electively underwent cardiac surgery were randomly allocated to a leukocyte depletion group (n=40) or a control(More)
To investigate brain changes in induced deep core hypothermia (15 degrees C) with circulatory arrest, five groups of neonatal pigs were subjected to cardiopulmonary bypass (CPB), with circulatory arrest (CA) periods varying from 70-120 min. The parameters analysed were: 1. Histology and electron microscopy of the brain six hours post-CPB, 2.(More)
Since the introduction of the pulmonary artery catheter (PAC) in 1970 by Swan et al., various complications are recognized with the insertion and the use of Swan-Ganz catheter. We present two different cases with rare but life threatening complications which had been successfully managed. The first case is a carotid cannulation with an 8.5 Fr introducer(More)
Congenital bronchogenic cysts of the lung and mediastinum develop from the ventral foregut during embryogenesis. Bronchogenic cysts are seldom seen in the adults and most are thought to be asymptomatic and free of complications unless they become infected or are large enough to cause pressure on contiguous vital structures such as the tracheal carina, the(More)
BACKGROUND Bland-White-Garland syndrome (anomalous origin of the left coronary artery from the pulmonary artery) is a rare disease which may result in myocardial infarction, congestive heart failure and sometimes death during the early infantile period. CASE PRESENTATION A successfully treated case of a 45-year-old mother of 2 children with(More)
Diaphragmatic hernia complicating pregnancy is rare and results in a high mortality rate, particularly if early surgical intervention is not undertaken. We report a case in which a woman presenting at 23 wk's gestation was admitted with symptoms of respiratory failure and bowel obstruction due to incarceration of viscera through a left posterolateral defect(More)
