BACKGROUND AND PURPOSE Until now, endovascular treatment of symptomatic atherosclerotic stenosis in small intracranial arteries (≤2.5 mm) was limited. We evaluated the safety and efficacy of the treatment by using Wingspan stents in arteries of this caliber. MATERIALS AND METHODS From March 2007 to July 2010, 53 symptomatic intracranial stenoses with narrowing of at least 50% in 53 patients w...

The branching pattern and vascular geometry of biological tree structure are complex. Here we show that the design of all vascular trees for which there exist morphometric data in the literature (e.g., coronary, pulmonary; vessels of various skeletal muscles, mesentery, omentum, and conjunctiva) obeys a set of scaling laws that are based on the hypothesis that the cost of construction of the tr...

In vascular cardiology, stenting coronary arteries with the diameter greater than that of the native artery has been used in an attempt to securely anchor the device against the arterial wall. Various stent-to-artery deployment ratios can be used by clinicians to implant the stent into the artery. However, stent expansion beyond the native artery diameter alters vascular hemodynamic scenarios. ...

abstract introduction: in this study the role of pge2 as an important inflammatory mediator in indomethacine and theophylline effects on joint diameter and vascular response of chronically inflamed rat knee joint to saphenous nerve stimulation was investigated. methods: inflammation was induced by intraarticular injection of 0.2 ml freund,s complete adjuvant (fca) and 3, 7, 14, 21 days post inj...

vegetation deterioration is a main cause of erosion and land degradation. therefore, land cover reclamation in the effected areas will affect erosion trend. in reclamation projects, the investigation of relationship between the planted species and soils is highly recommended. atriplex species can sequester carbon into soil, and have an ability to conserve soil and prevent soil erosion, as well....

PURPOSE The purpose of this study was to share our experience of transcatheter closure of small patent ductus arteriosus (PDA) by using an Amplatzer vascular plug (AVP). METHODS We reviewed the medical records of 20 patients who underwent transcatheter closure at Samsung Medical Center and Sejong General Hospital from January 2008 to August 2012. The size and shape of the PDAs were evaluated ...
