Cryptogenic cerebral ischemia: clinical usefulness of a flexible ultrasound diagnostic algorithm for detection of patent foramen ovale.


OBJECTIVES Paradoxical thromboembolism across a patent foramen ovale (PFO) may be involved in the pathogenesis of cryptogenic strokes. We tested the feasibility and the clinical usefulness of an early screening for PFO combining different ultrasound techniques in patients with acute cerebral ischemia of undetermined cause. METHODS Consecutive patients… (More)
