BACKGROUND Wave reflection may be an important influence on blood pressure, but the extent to which reflections undergo attenuation during retrograde propagation has not been studied. We quantified retrograde transmission of a reflected wave created by occlusion of the left femoral artery in man. METHODS 20 subjects (age 31-83 years; 14 male) underwent invasive measurement of pressure and flo...

Radial access combined with hemodynamic support has the limitation of not allowing adequate angiography or delivery peripheral balloons for managing femoral site after removal large sheath. We present a case series use novel long 6 French guiding sheath via left radial artery ventricular assist device vascular closure devices.

Limb vascular conductance responses to pharmacological and nonexercise vasodilator stimuli are generally augmented in women compared with men. In the present investigation, we tested the hypothesis that exercise-induced vasodilator responses are also greater in women than men. Sixteen women and 15 men (20-30 yr) with similar fitness and activity levels performed graded quadriceps exercise (supi...

OBJECTIVE We examined the time course of arteriogenesis (collateral artery growth) after femoral artery ligation and the effect of monocyte chemoattractant protein-1 (MCP-1). METHODS New Zealand White rabbits received MCP-1 or phosphate buffered saline (PBS) for a 1-week period, either directly or 3 weeks after femoral artery ligation (non-ischemic model). A control group was studied with int...

Purpose Observation of blood supply to the femoral head is significantly important when interruption occurs such as a femoral neck fracture, which easily leads to avascular necrosis (AVN) or transient bone marrow edema. However, the observation of blood supply to the femoral head is anatomically difficult due to their small size and amount of blood supply. Today, observation of the feeding arte...

INTRODUCTION The best techniques for reduction of femoral access site complications after transcatheter aortic valve implantation (TAVI) remain the object of research. AIM We report on a single center's experience with TAVI performed via the femoral access site. MATERIAL AND METHODS Between September 2010 and September 2015, 152 consecutive patients underwent TAVI in our department. Of them...

The main focus of the preliminary work presented here is the automatic real-time annotation (detection and tracking) of the important structures seen in an ultrasound image taken from a femoral nerve block, i.e. the femoral artery, the facias (lata and illiaca) and the femoral nerve.
