BACKGROUND Reconstruction of soft tissue defects in the lower third of the leg remains challenging. Anatomical constraints limit the local options available for complex defects especially lower third of leg. Local flaps based on perforator vessels are raising interest in reconstructive surgery of the limbs. We present our experience with perforator flaps for reconstruction of soft tissue def...

OBJECTIVE To assess the influence of preload reduction by hemodialysis on Doppler Tei Index of myocardial performance and other parameters of cardiac function. METHODS The Tei index and left ventricular (LV) systolic and diastolic function parameters were estimated, before and after a single hemodialysis session. Only subjects who were in sinus rhythm, without history of coronary artery disea...

background: numerous studies have now demonstrated that heart failure with a normal ejection fraction (hfnlef) is common. hypertension is also the most commonly associated cardiac condition in patients with hfnlef. despite the observed link between microalbuminuria, obesity, and cardiovascular disorders, this question has remained ― ‘which is more important for the prediction and prevention of ...

The use of Doppler ultrasound in rheumatology has grown in recent years. This is partly due to the increasing number of rheumatologists who perform US in their daily clinical practise and also to the technological advances of US systems. Both colour Doppler and power Doppler are used to evaluate the degree of intra- and peri-articular soft tissue inflammation. Moreover, Doppler US has been foun...

Tissue Doppler imaging was used with transthoracic and transesophageal echocardiography to determine its clinical usefulness beyond visualization of ventricular wall motion. Thirteen novel applications were found: acoustically difficult transthoracic studies, thrombus, mitral chordal motion, shunt detection using saline contrast, spontaneous echo contrast, intra-aortic balloon pump position and...

Blood and tissue velocities are measured and analyzed in cardiac, vascular, and other applications of diagnostic ultrasound. Errors in system performance might give invalid measurements. We developed two moving string test targets and a rotating cylinder phantom (Doppler phantoms) to characterize Doppler ultrasound systems. These phantoms were initially used to measure such variables as sample ...
