Successful repair of traumatic aortic tears using left heart bypass.
Aortic tears commonly occur in multiply injured patients. Recognizing this injury is important. A chest X-ray is helpful and a CT-angiogram or aortogram confirmatory. After attending to life-threatening injuries, the aortic tear should be repaired immediately. Using the left heart bypass technique has the lowest risk of operative neurologic injury. We review our experience over the last 2 years...

متن کاملImpact of Left Heart Bypass on Arterial Oxygenation During One-Lung Ventilation for Thoracic Aortic Surgery.
OBJECTIVE The aim of this study was to reveal the mechanism of improved arterial oxygenation by measuring the changes in oxygenation before and after initiation of left heart bypass (LHB) during one-lung ventilation (OLV) for thoracic aortic surgery. DESIGN Prospective, observational study. SETTING Single-institution, private hospital. PARTICIPANTS The study comprised 50 patients who unde...
متن کاملReduction of the oxygen utilization of the heart by left heart bypass.
• Keports of support of the heart in acute failure both in man and in experimental animals" have been published. The means investigated include: (1) heart-lung bypass, from the cava through an oxygenator and pump to the aorta;'" (2) veno-arterial pumping without oxygenator ; ' ' ' 3 ' 4 > (3) aortic synchronized counter pulsation to lower the pressure during left ventricular ejection and to rai...
