The sub trochanteric zone of the femur is the area extending up till 5 cm distally from the inferior border of the lesser trochanter or the junction of the proximal third and middle third of the femoral shaft. Fracture patterns presenting major displacement in this area are considered sub trochanteric fractures despite their proximal or distal extension. 1 High biomechanical stress concentratio...

We hypothesized that the endogenous coronary vasodilator adenosine may reduce infarct size by progressively increasing reflow in a preparation of coronary occlusion-reperfusion. After 90 min of proximal left anterior descending artery occlusion, 20 dogs were randomized to blood reperfusion with (n = 10) or without (n = 10) adenosine into the proximal left anterior descending vessel at 3.75 mg/m...

INTRODUCTION The purpose of the current study was to investigate the reaction of the femur to the implantation of the MiniHipTM in terms of: (1) bone density change during one year; (2) correlations between stem length, CCD (caput-collum-diaphyseal), femoral offset, T-value, and bone density; (3) other co-variables that influence the change of bone density. PATIENTS AND METHODS MiniHipTM impl...

ObjectiveWith growing experience of acute type A aortic dissection repair, Zone 2 arch repair has been advocated. The aim this study is to compare the outcome between “proximal-first” and “arch-first” repair.MethodsFrom January 2015 March 2023, 45 patients underwent out 208 repairs: arch-first, N = 19, proximal-first technique, 26, since 2021. Indications were or descending tear, complex in nec...

BACKGROUND The fractional flow reserve (FFR) value of 0.75 has been validated against ischemic testing, whereas the FFR value of 0.80 has been widely accepted to guide clinical decision making. However, revascularization when FFR is 0.76 to 0.80, within the so-called gray zone, is still debatable. METHODS AND RESULTS From February 1997 to June 2013, all patients with single-segment disease an...
