Randomized Controlled Trial Multicenter Study Clinical TrialDuraflo II coating of cardiopulmonary bypass circuits reduces complement activation, but does not affect the release of granulocyte enzymes : a European multicentre study.
This study was carried out to: (a) compare complement and granulocyte activation during cardiac operations in patients operated with cardiopulmonary bypass coated with heparin by the Duraflo II method, with activation in patients operated with uncoated circuits; and (b) relate complement, and granulocyte activation to selected adverse effects. ⋯ It is concluded that the Duraflo II heparin coating reduces complement activation, particularly TCC formation, during CPB, but not the release of specific neutrophil granule enzymes. No certain correlation was established between complement and granulocyte activation and clinical outcome.

Randomized Controlled Trial Comparative Study Clinical TrialEEG changes during cardiopulmonary bypass surgery and postoperative neuropsychological deficit: the effect of bubble and membrane oxygenators.
Quantitative electroencephalography was used during cardiopulmonary bypass surgery to determine the point in time of most neuronal functional change which may result in postoperative neuropsychological deficit. It was also used to determine any relationship between quantitative electroencephalography changes and type of oxygenator used in surgery. ⋯ While no difference in anaesthetic technique was found between patients, the variation in quantitative electroencephalography power before perfusion may indicate a difference in individual response to anaesthetic. Usefulness of quantitative electroencephalography to predict postoperative cerebral functional deficit remains doubtful.

Comparative StudySurgical treatment for life-threatening acute myocardial infarction: a prospective protocol.
In this paper we describe the preliminary results of a prospective operative protocol designed in order to define the role of emergent myocardial revascularization in extensive acute myocardial infarction and in post-infarction cardiogenic shock. ⋯ Experience of 9 months with this prospective protocol showed its effectiveness in the management of critically ill patients with acute coronary occlusion leading to low mortality rate in acute myocardial infarction and improved survival rate in post-infarction cardiogenic shock.

Dysphagia aortica describes swallowing difficulty caused by external compression from a tortuous or aneurysmal aorta. We present 5 cases in which dysphagia to solids accompanied a localised high pressure barrier (HPB) on manometry suggestive of dysphagia aortica, and explore other investigation modalities useful to confirm the diagnosis. ⋯ Dysphagia aortica commonly coexists with motility disorders and GORD. Video solid bolus swallow allowed us to determine the clinical significance of a manometric HPB in 4 out of 5 patients suspected on dysphagia aortica where standard evaluation would have failed. We recommend its use in those patients with a manometric HPB suggestive of dysphagia aortica in whom standard barium swallow is normal.

Case ReportsPercutaneous occlusion of the entry to a leaking false aneurysm after ascending aortic replacement for aortic dissection type A facilitating surgical repair.
A leaking false aneurysm occurred after ascending aortic replacement for aortic dissection type A. Percutaneous balloonocclusion of the entry to the false aneurysm facilitated elective surgical repair.
