Background and Purpose The purpose of this study is to demonstrate the magnetic resonance features of intracranial vertebrobasilar artery dissections and to determine the potential and limitations of magnetic resonance imaging in their diagnosis. Methods We studied five consecutive patients with angiographically verified intracranial vertebrobasilar artery dissection with magnetic resonance ima...

BACKGROUND The intramural coronary artery has been known as a risk factor for early death after an arterial switch operation (ASO). We reviewed the morphological characteristics and evaluated the early and mid-term results of ASO for patients with an intramural coronary artery. MATERIALS AND METHODS From March 1994 to September 15th 2010, 158 patients underwent ASO at Dong-A and Pusan Nationa...
