Article Synopsis
- Thoracic outlet syndrome (TOS) is a rare problem mainly affecting younger people and diagnosing it can take a long time, which is not good for patient health.
- Digital subtraction angiography (DSA) is usually used to diagnose TOS, but it uses radiation which can be harmful to younger patients.
- The study found that ultrasound (US) is a better option because it doesn't use radiation, is easy to access, and works well for diagnosing arterial TOS (aTOS).
Article Synopsis
- Ultrasonography is a non-invasive method used to efficiently evaluate stenosis or occlusions in the brain-supplying arteries in patients with cerebrovascular diseases.
- The article outlines standardized techniques for assessing extracranial carotid and vertebral arteries, including grading criteria for internal carotid artery stenosis and recommendations for documenting findings.
- Additionally, it includes guidelines for measuring intima-media thickness, classifying atherosclerotic plaques, and diagnosing conditions like in-stent stenoses, vertebral artery dissections, and subclavian steal syndrome.
Ultrasonography of intracranial arteries is a non-invasive and highly efficient method for the diagnosis and follow-up of patients with cerebrovascular diseases, also in the bedside setting of the critically ill. For reliable assessment and interpretation of sonographic findings, the technique requires - apart from dedicated anatomic and pathophysiological knowledge of cerebral arteries and their hemodynamics - the comprehension of alternative imaging modalities such as CT or MR angiography. This article reviews the transcranial color-coded duplex sonographic (TCCS) examination technique including the transcranial Doppler sonography (TCD) for a standardized ultrasound assessment of the intracranial arteries and typical pathological cases.

Article Synopsis
- Implantable cardioverter defibrillators (ICDs) help prevent sudden heart problems, but sometimes they can give shocks at the wrong times, which is not good for people.
- This study looked at using a special device called laser Doppler flowmetry to check how the heart is doing during fast heart rates caused by atrial and ventricular issues.
- The results showed that laser Doppler flowmetry worked well to measure blood flow and was better at spotting heart problems than just looking at the heart rate alone.
