BACKGROUND AND PURPOSE Cryptogenic stroke is common in patients with transient ischemic attack (TIA) and minor stroke. It is likely that the imaging recurrence risk is higher than the clinical recurrence rate. We sought to determine the rate of clinical and radiographic stroke recurrence in a population of cryptogenic TIA and minor stroke. METHODS Patients with TIA/minor stroke (National Inst...
Ischemic stroke is a complex multifactorial disease and approximately 30%, especially in the young, are cryptogenic. In some of the patients with cryptogenic ischemic stroke the underlying risk factor may be a prothrombotic state. We studied 101 patients with ischemic stroke under 55 years of age. All the patients underwent an extensive diagnostic evaluation to determine the cause of stroke. Co...
BACKGROUND AND PURPOSE Brain infarct patterns that are observed via diffusion-weighted imaging are useful for classifying stroke subtypes. However, it is unclear whether infarct patterns can predict long-term outcomes in cryptogenic stroke patients. Herein, we investigated the association between acute brain infarct patterns and long-term stroke outcomes in cryptogenic stroke patients. METHOD...
INTRODUCTION AND OBJECTIVES To investigate the relationship between patent foramen ovale and cryptogenic stroke in patients aged > or =55 years. METHODS This prospective study determined the presence of patent foramen ovale and atrial septal aneurysm using transesophageal echocardiography in 262 consecutive patients with a diagnosis of probable cryptogenic stroke. Data from 44 patients aged >...
BACKGROUND The left atrial septal pouch (LASP), an anatomic variant of the interatrial septum, has uncertain clinical significance. We examined the association between LASP and ischemic stroke subtypes in patients undergoing transesophageal echocardiography (TEE). METHODS We determined the prevalence of LASP among consecutive patients who underwent TEE at our institution. Patients identified ...
Cryptogenic stroke represents one third of ischemic strokes, initial work up includes Computed Tomography (CT), Magnetic resonance imaging (MRI), laboratory investigations, Electrocardiogram (ECG) and Echocardiography either transthoracic (TTE) or Transesophageal (TEE). Patent foramen ovale (PFO) which is seen in between 15% and 25% of adults has been identified as a source for cryptogenic isch...
Introduction: Celiac disease (CD) is a disease that involves many organs including the liver and is caused by autoimmune enteropathy. We aimed to compare the CD frequency between the cryptogenic cirrhosis and cirrhosis due to hepatitis B virus (HBV) and hepatitis C virus (HCV). Materials and methods: Patients with cryptogenic cirrhosis (n=83), HCV related cirrhosis (n=42) and HBV related cirrho...
