Venous thromboembolism (VTE) is the third most common vascular disease. Medical inpatients, long-term care residents, persons with minor injuries, and long-distance travelers are at increased risk…
In recent years, increasing attention has been paid to cryptogenic stroke (CS) caused by the patent foramen ovale (PFO). This study aims to compare contrast transthoracic echocardiography (cTTE) and contrast transcranial Doppler (cTCD) to determine whether cTTE is more suitable and reliable than cTCD for clinical use….
Transcranial Doppler is a bedside procedure that measures linear cerebral blood flow velocity (CBFV) and the pulsatility index through the intracranial circulation. Transcranial color-coded duplex Doppler (TCCD) provides both CBFV and B-mode functions…
Intracranial arterial stenosis may progress or regress, of which the diagnosis is important to predict the risk of stroke or to evaluate the response of treatment. Transcranial Doppler (TCD) seems to be useful for this purpose, however, optimal diagnostic criteria have not been validated yet…
Four-dimensional phase-contrast magnetic resonance imaging enables quantification of blood flow rate (BFR; mL/min) in multiple cerebral arteries simultaneously, making it a promising technique for hemodynamic investigation in patients with stroke…
Ageing reduces cerebral blood flow (CBF), while mean arterial pressure (MAP) becomes elevated. According to ‘the selfish brain’ hypothesis of hypertension, a reduction in vertebral artery blood flow (VA) leads to increased sympathetic activity and thus increases MAP…
Brain ultrasonography can be used to evaluate cerebral anatomy and pathology, as well as cerebral circulation through analysis of blood flow velocities…
Results show the short-term risk of hemorrhage in treating patients with acute transient ischemic attack (TIA) or minor acute ischemic stroke (AIS) with clopidogrel plus aspirin or aspirin alone…
In 2005, the American Stroke Association published recommendations for the establishment of stroke systems of care and in 2013 expanded on them with a statement on interactions within stroke systems of care…
Stroke thrombolysis with alteplase is currently recommended 0-4·5 h after stroke onset. We aimed to determine whether perfusion imaging can identify patients with salvageable brain tissue with symptoms 4·5 h or more from stroke onset or with symptoms on waking who might benefit from thrombolysis.
Elective endovascular repair of an abdominal aortic aneurysm results in lower perioperative mortality than traditional open repair, but after 4 years this survival advantage is not seen; in addition, results of two European trials have shown worse long-term outcomes with endovascular repair than with open repair…
Is contrast-enhanced ultrasound (CEUS) superior to computed tomography angiography (CTA) in detection of endoleaks in post-EVAR patients? A systematic review and meta-analysis. Harky Amer, Zywicka Ewa, Santoro Giovanni, Jullian Lucas, Joshi Mihika, Dimitri Sameh Abstract Objective: The purpose of this systematic review and meta-analysis was to assess the sensitivity and specificity of contrast-enhanced ultrasound (CEUS)…
