BACKGROUND Uncertainty exists over whether listening for carotid bruits as part of the clinical examination is informative in terms of predicting the presence or severity of carotid stenosis. AIM We sought to undertake a comprehensive meta-analysis and meta-regression of all studies to date that have assessed the relationship between a carotid bruit and severity of degree of stenosis. METHO...

Inflammation appears to be the cause of aortic valve (AoV) stenosis and identification of predictive biomarkers is therefore imperative. The aim of the current study was to evaluate the potential role of serum chemerin and fibroblast growth factor-21 (FGF-21) in the pathogenesis of the disease. A total of 102 patients were selected based on certain criteria and divided into an aortic stenosis g...

Purpose: To evaluate the effect of stenosis nature on success of silicone intubation for nasosolacrimal duct stenosis (NLDS) in adults (patent nasolacrimal duct with resistance to positive-pressure irrigation) Methods: An interventional case series of consecutive monocanalicular and bicanalicular silicone intubation for nasolacrimal duct stenosis in adults were reviewed. The severity of the ste...

We studied two similar cases of severe subglottic stenosis secondary to trauma with different treatment modalities. One had laryngotracheal reconstruction with cartilage augmentation and the other had laryngotracheal resection anastomosis. We wish to compare the two popular choices of surgery for laryngotracheal stenosis from two cases with similar nature and severity thus highlighting the comp...

OBJECTIVES This study was conducted to determine the utility of aortic valve resistance in assessing the severity of aortic stenosis. BACKGROUND Assessment of the severity of aortic stenosis has traditionally employed hemodynamic data and the Gorlin formula to calculate the area of the aortic valve. Recently, flow dependence of the Gorlin formula has been identified and the accuracy of the fo...

The coronary Doppler catheter has been used primarily in the measurement of coronary vasodilator reserve, most often as the ratio of peak to resting velocity in response to an intracoronary dose of papaverine. We have developed a new method based on the continuity equation using a Doppler catheter for the assessment of stenosis severity in the coronary circulation by means of quantitative veloc...

BACKGROUND Little is known regarding intravascular ultrasound (IVUS) criteria to determine the functional severity of coronary stenosis. Recently, fractional flow reserve (FFR) has emerged as a lesion-specific index of the functional severity of a coronary stenosis that is independent of systemic hemodynamic variability. The present study was undertaken to determine the IVUS parameters for the ...

Anal stenosis is a rare debilitating surgical condition that secondary to functional and anatomical causes. Excisional hemorrhoidectomy the leading cause of anal stenosis, affecting up 87.7% cases. The severity level impacted region determines management options considered. Numerous tension-free anoplasty techniques their varying success rates have been reported in literature. A patient-tailore...

Real-time, cross-sectional echocardiograms were recorded in 28 consecutive adult patients with valvular aortic stenosis using a high resolution, mechanical sector scanner. Using the cross-sectional technique, the aortic valve orifice diameter was recorded in each of the 28 patients. With M-mode echocardiographic examination of these same patients, this value could be estimated in only 21 of the...
