Up to a third of strokes are rendered cryptogenic or of undetermined etiology. This number is
specifically higher in younger patients. At times, inadequate diagnostic workups, multiple …

Atrial fibrillation and severe carotid-artery stenosis are well characterised risk factors for
stroke; each is present in about a fifth of patients. The identification of such risk factors in …

Aortic arch atheroma is a frequent finding in ischemic stroke patients. Its role as a source of
cerebral emboli or a marker of atherosclerosis is unclear. Transesophageal echography is …

Background and Purpose—Proximal aortic plaques are a risk factor for vascular embolic
events. However, this association in the general population is unclear. We sought to assess …

Acute multi‐territory, embolic cerebral infarctions are often associated with serious
underlying clinical conditions including the presence of highly “active” emboligenic sources …

Transcranial Doppler can detect microembolic signals which are characterized by
unidirectional high intensity increase, short duration, random occurrence, and a “whistling” …

Background Complex aortic plaque (CAP) is a potential embolic source in patients with
cryptogenic stroke (CS). We review CAP imaging criteria for transesophageal …

Severe atheroma of the aortic arch has now been established as an important risk factor and
mechanism for stroke and peripheral embolism. The odds ratio for stroke or peripheral …

Background: Aortic arch atheroma (AAA) has been accepted as a possible embolic source
in patients with ischemic stroke, especially cryptogenic stroke. However, despite its well …

Cryptogenic stroke represents a diagnostic challenge. Several conditions have been found
to be more frequent in patients with cryptogenic stroke. Aortic arch atheroma (AAA) and …
