Randomized Controlled Trial Comparative Study Clinical Trial
Blood loss in infants and children for open heart operations: albumin 5% versus fresh-frozen plasma in the prime.
Infants and children undergoing cardiopulmonary bypass become substantially hemodiluted secondary to the volume used to prime the oxygenator. Fresh-frozen plasma has been included in the prime to lessen dilution of clotting factors and correspondingly minimize blood loss and transfusions. ⋯ Substitution of albumin 5% for fresh-frozen plasma in the prime of acyanotic patients weighing 10 kg or less who undergo noncomplex operations requiring cardiopulmonary bypass significantly reduces perioperative transfusions without increasing blood loss. Further investigation is needed to determine whether increased blood loss is associated with increased transfusions when albumin 5% is substituted for fresh-frozen plasma in the prime of infants and children who are cyanotic or undergoing complex operations.

Clinical Trial Controlled Clinical Trial
Cognitive changes with coronary artery disease: a prospective study of coronary artery bypass graft patients and nonsurgical controls.
Cognitive impairment after coronary artery bypass grafting (CABG) is well recognized, but previous investigations have been limited by lack of an appropriate control group. We compared changes in cognitive performance at 3 and 12 months after CABG with those in a control group of patients with comparable risk factors for coronary artery disease (CAD) who had not undergone surgery. ⋯ The prospective longitudinal neuropsychological performance of patients with CABG did not differ from that of comparable nonsurgical control subjects with CAD at 3 months or 1 year after base line examination. This suggests that the previously reported cognitive decline during the early postoperative period after CABG is transient and reversible. Continued follow-up will determine whether a specific "late decline" occurs in CABG patients but not in nonsurgical control subjects with similar risk factors for cardiovascular and cerebrovascular disease.

Randomized Controlled Trial Comparative Study Clinical Trial
Suction versus water seal after thoracoscopy for primary spontaneous pneumothorax: prospective randomized study.
The objectives of the study were to review our experience of video-assisted thoracoscopic apical pleurectomy and to evaluate whether suction or water seal is superior in the postoperative treatment of primary spontaneous pneumothorax. ⋯ Video-assisted thoracoscopic apical pleurectomy is effective and safe for treating primary spontaneous pneumothorax. Placing chest tubes on water seal after a brief period of suction shortens the duration of chest tube placement and hence the hospital stay.

We report a patient with a traumatic arteriovenous fistula between the ascending aorta and innominate vein, presenting 4 years after injury. Diagnostic imaging and surgical management of this rare manifestation of thoracic great vessel injury is described.

Children with cyanotic congenital heart disease may experience the development of abnormal vessels that become a source of significant morbidity. Abnormal vessel proliferation in these children may take several forms, including systemic-to-pulmonary collateral arteries, systemic-to-pulmonary venous collaterals, systemic venous collateral channels after bidirectional cavopulmonary anastomosis, and pulmonary arteriovenous malformations. However, no entity responsible for these abnormalities has been identified yet. This study determined whether children with cyanotic congenital heart disease have elevated serum levels of vascular endothelial growth factor (VEGF) and whether elevated VEGF correlated with these abnormal vessels. ⋯ Children with cyanotic heart disease have elevated systemic levels of VEGF, especially in those patients with a single ventricle associated with asplenia syndrome. There was no significant relationship in VEGF levels between the patients with abnormal vessels and without these vessels.
