In developed countries, stenosis is the main cause of death. To investigate hemodynamics within different degrees stenoses, a model incorporating fluid–structure interaction and microcirculation function used in this paper. Microcirculation treated as seepage outlet boundary condition. Compliant arterial wall considered. Numerical simulation based on performed using finite element method. Our r...

background: more diagnostic techniques require a better understanding of the forces and stresses developed in the wall of the left ventricle. the aim of this study was to differentiate significant coronary artery disease (cad) patients using a non-invasive quantification of myocardial wall stress in the diastole phase. methods: sixty male subjects with sinus rhythm (30 patients with significant...

percutaneous coronary angioplasty (ptca) of a coronary stenosis without documented ischemia at noninvasive stress testing is often performed, but its benefit is unproven. coronary pressure– derived fractional flow reserve (ffr) is an invasive index of stenosis severity defined as the ratio of maximal blood pressure in a stenotic vessel to the normal maximal pressure in the same vessel. ffr is a...

Background: The syndrome of degenerative lumbar canal stenosis accounts for a large percentage causes low back pain in the elderly worldwide. Surgical management has demonstrated better clinical and radiological results than conservative treatment. It allows adequate decompression thecal sac compressed nerve roots. However, aggressive laminectomy with facetectomy been linked many postoperative ...

SUMMARY A radiologically gasless abdomen in a neonate with EA is usually regarded as being pathognomonic of an absence of distal T.E.F. It has been estimated that up to 1.5% of patient with a distal fistula may have a radiologically gasless abdomens as a manifestation of a very small fistula plugged with mucus. In this case a contrast study via the gastrostomy demonstrated a fistula between th...

Objective: Lumbar spinal canal stenosis (LSCS) has prominent position in spinal disorders of the elderly. Ligamentum flavum hypertrophy plays a dominant role in narrowing of the LSCS. There are some clues that Ligamentum flavum hypertrophy is associated with diabetes mellitus. Our objective was comparison of histological properties of ligamentum flavum in Lumbar spinal canal stenosis patients w...
