BACKGROUND Atrial septal aneurysm has been considered a potential source of cardiogenic embolism for many years. The present study evaluated the prevalence and characteristics of atrial septal aneurysm in a patient population with stroke and normal carotid arteries compared to a control population without stroke. METHODS A total of 606 patients were enrolled between November 1990 and December...

BACKGROUND Percutaneous transcatheter closure of patent foramen ovale has been proposed to prevent recurrent strokes in young adults. Contrast transcranial Doppler ultrasonography provides a functional, semiquantitative evaluation of right-to-left cardiac shunt. AIMS To evaluate the efficacy of percutaneous closure of patent foramen ovale in suppressing right-to-left shunt (assessed using tra...

TELEMENTORING USING GOOGLE GLASS Using a wearable computer, known as “Google Glass,” physicians at the University of Arkansas for Medical Sciences (UAMS), Drs. Barry Uretsky, Abdul Hakeem, and Christian Assad-Kottner (Fig.1) performed an interventional patent foramen ovale (PFO) closure procedure with the assistance of a congenital heart expert, Dr Eudice Fontenot, of the Arkansas Children’s Ho...

BACKGROUND AND PURPOSE Paradoxical embolization is frequently posited as a mechanism of ischemic stroke in patients with patent foramen ovale. Several studies have suggested that the deep lower extremity and pelvic veins might be an embolic source in cryptogenic stroke (CS) patients with patent foramen ovale. METHODS Consecutive adult patients with ischemic stroke or transient ischemic attack...

BACKGROUND This randomized clinical trial compared rates of stroke or transient ischemic attack recurrence or death in patients with cryptogenic stroke and patent foramen ovale (PFO) who received medical treatment with aspirin or warfarin. MATERIALS AND METHODS Forty-four Iranian patients with cryptogenic stroke and patent foramen ovale participated in this randomized, single-blind trial betw...

The endovascular treatment of spontaneous dural cavernous sinus fistula (DAVF) can be accomplished by arterial approach, just with symptoms relief, or by numerous venous approaches through the inferior petrosal sinus, ophthalmic vein, anterior or posterior intercavernous sinus and facial vein. Our case suggests the approach to the cavernous sinus via the foramen ovale and emissary veins punctur...
