Introduction Cholesterol crystal embolism is a rare microembolic disease caused by cholesterol crystals that can present with various symptoms after vascular surgery, catheterization, or anticoagulation therapy. We report case of penile ulceration embolism. Case presentation A 72‐year‐old man undergoing maintenance dialysis for end‐stage renal failure presented pain and black glans ulcer. Despi...

The search for embolic sources has high priority in patients presenting with suspected cerebral embolism. Non-invasive cardiovascular ultrasound is frequently used to reveal the presence of carotid stenosis and cardiac disorders with embolic potential. Transesophageal echocardiography (TEE) provides images of aortic atherosclerosis, shown to be associated with increased risk of stroke. Some gui...

BACKGROUND AND PURPOSE Clinical thromboembolism (TE) remains an impediment to the chronic application of ventricular assist devices (VADs). Microembolic signals (MES) have been detected by transcranial Doppler ultrasound (TCD) in patients with VADs, although their origin and relation to TE remain undefined. We have investigated the hypothesis that hemostatic alterations are related to MES and t...

BACKGROUND AND PURPOSE The present study investigated the influence of the antiplatelet agent acetylsalicylic acid (ASA) on cerebral microembolism as detected by transcranial Doppler sonography (TCD). METHODS Nine patients with recent transient ischemic attack or minor stroke of arterial origin were investigated. Eight had not received an antiplatelet or anticoagulant medication before TCD, a...

The artery of Percheron (AOP) is an uncommon variant the posterior cerebral that supplies blood to paramedian thalamus and rostral midbrain. AOP often difficult recognize with intracranial magnetic resonance angiography due its small size. Although a number case reports occlusion have been published, cause mostly unclear. We experienced which resulted in bilateral thalamic infarction. It was mo...

Background: To evaluate the association between pre/post-procedural high sensitive C-reactive protein (hs-CRP) level and hs-CRP difference, and the risk of major adverse cardiovascular events (MACE) or new diffusion-weighted MRI lesions after carotid angioplasty and stenting (CAS). Methods: In this study, conducted in 2016 in Shiraz (Iran), patients who underwent diagnostic angiography and CAS...

A variation in right atrial and pulmonary arterial pressure might result in a shunt dynamic across a patent foramen ovale (PFO). In the present study we tested if peak exercise facilitates a restoration of right to left shunt (RLS) in stroke patients who demonstrated a functional PFO closure (no evidence of RLS across an initially demonstrated PFO). In stroke patients with PFO demonstrating a f...

Objectives Microembolic signals (MES) on transcranial Doppler (TCD) predict stroke and cognitive decline. Plasma levels of total homocysteine (tHcy), a prothrombotic factor, are higher in patients with microemboli in carotid stenosis and in patients with paradoxical embolism. In this study we assessed the association between the level of tHcy and the number of MES in patients with mechanical he...
