Thirty-one patients who were undergoing cardiopulmonary bypass for elective aortic valve replacement were studied. The effects on some aspects of lung function of intravenous methyl prednisolone, administered immediately before bypass, were assessed by measuring alveolar-arterial oxygen differences and shunt fractions. No significant differences in pulmonary function were found between the trea...

Adaptation of saphenous vein to the hemodynamic stresses of the arterial circulation is critical to the maturation of vein bypass grafts. We have investigated early adaptive responses of venous endothelium by placing excised human saphenous vein in a bypass circuit with either venous or arterial flow conditions, using external stenting to resolve the effects of longitudinal (shear) from circumf...

A venous bypass technique (BP) that does not require the use of systemic anticoagulation is used routinely at our institution in all adult patients during the anhepatic phase of liver transplantation (LT). Complete cardiopulmonary profiles were obtained in a subset of 28 consecutive cases. During the anhepatic phase while on bypass, mean arterial pressure, central venous pressure, and pulmonary...

[Purpose] This study aimed to evaluate the effect of in-hospital physical activity on patient prognosis after lower extremity bypass surgery for peripheral arterial disease. [Subjects and Methods] A total of 13 patients (16 limbs; 11 males and 2 females; mean age [standard deviation], 72.8 [5.9] years) who underwent lower extremity bypass surgery for Fontaine stage 2 peripheral arterial disease...

We sought to determine the behavior of intrinsic cardiac neurons in human subjects undergoing cardiac surgery and to correlate their activity with hemodynamics status. A lead II electrocardiogram, pulmonary artery pressure, and systemic arterial pressure were recorded along with extracellular activity generated by right atrial neurons in 10 patients undergoing coronary artery bypass surgery. Id...

The use of an arterial line filter (ALF) within the pediatric cardiopulmonary bypass (CPB) circuit is not a new concept. It has always presented the perfusionist with a circuit component that while valuable, increased prime volume. The purpose of this study was to evaluate the change in prime volume and emboli between a conventional oxygenator with separate ALF and a new generation oxygenator w...

BACKGROUND Extracranial-to-intracranial (EC-IC) arterial bypass is a technically demanding procedure used to treat complex cerebral artery diseases. The indications, proper surgical techniques, and outcomes of this procedure have been under debate over the recent decades. METHODS Between January 2004 and December 2012, 28 patients, including patients with cerebral artery occlusion, intracrani...

Abstract Endovascular therapy, as opposed to surgical bypass, has become the mainstay for peripheral arterial disease even in long segment occlusions. Complications can occur during access, catheter manipulation, balloon dilation, and/or stent placement. Given high prevalence of comorbidities such diabetes, hypertension, renal dysfunction, and coronary artery these patients, early identificatio...

Deep vein arterialization (DVA) is a therapeutic option in “no option” for revascularization chronic limb-threatening ischemia patients, creating an arteriovenous bypass between proximal artery and distal deep venous target at the ankle. Imaging plays crucial role peripheral arterial disease (PAD) patient management. We present case of 71-year-old PAD (Rutherford class 5) with focal gangrene fi...

conclusions propofol provided a safe and acceptable sedation for post-cabg surgical patients, significantly reduced the requirement for analgesics, and allowed for more rapid tracheal extubation than midazolam but did not result in earlier icu discharge. results the depth of sedation was almost the same in the two groups (rss=4.5 in midazolam group vs 4.7 in propofol group; p = 0.259) but the t...
