introduction: in order to assess our skill in the tubularized incised plate (tip) urethroplasty technique in children with hypospadias. material andmethods: of 307 children (mean age 38 month) who received a tip urethroplasty, all had primary hypospadias. patients who were referred with complication were eliminated from our study. the hypospadias defects were subcoronal in 25 (8%), distal penil...

background: carotid artery stenting (cas) has recently been recommended as an alternative to carotid endarterectomy (cea) by some clinicians. objective: this study was designed to evaluate the success rate and in-hospital and 30-day adverse events in our first experiences in iran for cas with protection devices, to document our results and guide further use of cas. methods: from december 2003 t...

conclusions stents would be regarded as a temporary means of reaching the ideal condition for resection and reconstruction in most patients with tracheal stenoses. although an optimal stent has not been introduced yet, we used polyflex stents in most of our patients with tracheal stenosis due to its availability and ease of use. we suggest that this method is safe and less time consuming than i...

AIMS Little is known about the medium term results after stenting of the arterial duct in neonates and infants with duct-dependent cyanotic congenital heart disease. We report the results of stent implantation of the arterial duct in 21 neonates and infants. The defects for which the arterial duct was stented included pulmonary atresia with intact ventricular septum, critical pulmonary stenosis...

BACKGROUND Recent studies show that coronary microcirculatory impairment is an independent predictor of poor outcomes in patients with cardiovascular disease. However, controversy exists over whether microcirculatory resistance, a measure of coronary microcirculatory status, is dependent on epicardial stenosis severity. Previous studies demonstrating that microcirculatory resistance is dependen...

Introduction: Vasodilatory stress is the standard paradigm for probing myocardial oxygenation (O2) changes due to coronary artery stenosis on the basis of BOLD MRI (1-3). However, since vasodilation is typically achieved with provocative stress, approaches that can identify the presence of stenosis on the basis of microvascular alterations at rest are highly desirable. It is known that myocardi...

BACKGROUND Arterial compliance and endothelium-dependent vasodilation are two characteristics of the vessel wall. In the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) study, we studied the relationships between arterial compliance and endothelium-dependent vasodilation versus atherosclerosis as measured with two imaging modalities. METHODS In the population-based PIV...

BACKGROUND AND PURPOSE We sought to investigate the association of cigarette smoking with high-grade carotid artery stenosis in Hispanic, black, and white patients with cerebral ischemia in two independent samples. METHODS Prospectively collected data from the Northern Manhattan Stroke Study (NOMASS) (n=431) and the Berlin Cerebral Ischemia Databank (BCID) (n=483) were used separately for a c...
