Article Synopsis
- Ultrasound (US) is a valuable tool for assessing acute tendon injuries, enabling quick evaluations and decisions on treatment at the bedside.
- It surpasses physical exams in sensitivity and specificity, making it critical for accurately identifying conditions like distal triceps tears that show similar symptoms but have different severities.
- US also helps characterize the injury's location and extent, which guides treatment choices, and can eliminate misdiagnoses by distinguishing between musculoskeletal and nonmusculoskeletal issues like deep venous thrombosis.
Should all critical care patients with a central venous catheter in situ be screened for central catheter related thrombosis?
Br J Hosp Med (Lond)
May 2024
Department of Anaesthesia, Peterborough City Hospital, North West Anglia NHS Foundation Trust, Peterborough, UK.
Article Synopsis
- There are limited studies specifically on central catheter related thrombosis (CCRT) in adults in critical care, despite many studies on CCRT in general.
- Research involving bedside duplex ultrasound has shown that the incidence of CCRT ranges from 17-38%, with most cases identified within a week of catheter insertion.
- Almost all cases of CCRT are asymptomatic, lacking serious complications like pulmonary embolism or significant mortality impacts, leading to the recommendation against routine screening for CCRT in these patients.

Department of Rehabilitation Medicine, Nanjing Drum Tower Hospital, The Affiliated Hospital of Nanjing University Medical School, 321 Zhongshan Road, Nanjing, 210008, Jiangsu, People's Republic of China.
Article Synopsis
- Deep vein thrombosis (DVT) is a serious risk for patients undergoing total hip arthroplasty (THA), especially if pre-surgical DVT is missed, as it can be mistaken for a post-operative condition.
- A study involving 1242 patients identified that 3.1% had preoperative DVT, with significant risk factors including age, D-dimer levels, female gender, and revision THA.
- The findings highlight that patients aged 75 and older, females, and those with higher D-dimer levels are particularly at risk, suggesting the need for careful preoperative screening.*
Article Synopsis
- * Emergency compression ultrasound (US) conducted by non-radiologists or cardiologists shows promising results for quickly and accurately diagnosing DVT, with sensitivity between 86-93% and specificity ranging from 90-97.1%.
- * For the effective implementation of emergency compression US as a diagnostic tool for DVT by general practitioners and emergency physicians, standardized training is essential to ensure high diagnostic accuracy.

Hospital Medicine, Inova Fairfax Hospital, Falls Church, USA.
Article Synopsis
- Pulmonary embolus (PE) is a serious condition that can be fatal if not treated quickly with anticoagulants, and diagnosing it can be difficult without advanced imaging like CT angiography.
- Point-of-care ultrasound (POCUS) is a valuable tool that can help directly assess deep vein thrombosis (DVT) and indirectly check for PE at the bedside.
- In a recent case, a patient with hypotension from a suspected urinary tract infection was found to have significant right heart strain and femoral DVT through POCUS, demonstrating its crucial role in evaluating cardiopulmonary issues.*
Article Synopsis
- Point-of-Care Ultrasound (POCUS) is a bedside imaging technique used by clinicians for quick diagnosis and monitoring of patients, often in emergency and inpatient settings.
- It enhances physical exams by providing real-time information, helping identify acute conditions like shock and respiratory issues, while also evaluating cardiac function and lung health.
- POCUS is valuable for assessing venous status, diagnosing abdominal fluid, detecting kidney congestion, and guiding invasive procedures, offering immediate feedback and the ability to perform repeat scans as necessary.
Fluoroscopically guided repositioning of peripherally inserted central catheter in patients failing ultrasound-guided-only placement: a retrospective five-year study.
Acta Radiol
June 2023
Department of Interventional Radiology, Qingdao Hospital, University of Health and Rehabilitation Sciences (Qingdao Municipal Hospital), Qingdao, PR China.
Article Synopsis
- Ultrasound-guided insertion of PICCs is generally safe but can be tricky in special cases, leading to failures in placement.
- This study analyzed 1560 patients, finding that fluoroscopically guided tip repositioning successfully corrected issues in 32 individuals who failed the initial ultrasound-guided attempts, with minimal complications.
- The findings suggest that fluoroscopic adjustments can improve success rates and should be recommended for patients who experience difficulties with ultrasound-guided PICC placements.

Point-of-Care Ultrasound in the Diagnosis of Venous Thoracic Outlet Syndrome.
J Emerg Med
December 2022
Department of Emergency Medicine, Emory University School of Medicine, Atlanta Georgia.
Article Synopsis
- Clinicians trained in point-of-care ultrasound (POCUS) can enhance their diagnostic capabilities, but the use of POCUS for diagnosing thoracic outlet syndrome (TOS) has not been widely documented.
- A case involving a 46-year-old man with progressive left upper extremity symptoms led to a POCUS examination that revealed signs of venous compression, ultimately diagnosing him with venous thoracic outlet syndrome (vTOS).
- Emergency physicians should recognize the importance of timely diagnosis and treatment of TOS to prevent chronic pain and disability, as POCUS can serve as an effective initial imaging tool in suspected cases of vTOS.

Department of Cardiology, University Medical Center of the Johannes Gutenberg-University, Mainz, Germany.
Article Synopsis
- In pregnant women experiencing acute pulmonary embolism (PE) with unstable blood flow, the initial diagnostic step is a bedside echocardiogram to evaluate right ventricular (RV) function.* -
- If RV dysfunction is detected, immediate treatment such as thrombolysis may be necessary despite its relative contraindication during pregnancy.* -
- Collaboration with a specialized multidisciplinary team is essential to determine the most appropriate treatment methods, which may include surgical options or catheter-directed therapies.*
Article Synopsis
- Point of care ultrasound (PoCUS) is valuable for diagnosing thrombosis related to central venous catheters used for dialysis, but its use is not widespread, leading to underdiagnosis of the condition.* -
- In a study, two medical students trained in a short PoCUS course assessed patients with central venous catheters, and their results were compared to experienced doctors using Doppler studies.* -
- The experts exhibited high accuracy with the compression technique for diagnosing thrombosis, while the students showed lower sensitivity, suggesting while training novices in PoCUS is possible, it may not yield reliable diagnostic results.*

Neurology Department, Coimbra University and Hospital Centre, Coimbra, Portugal.
Article Synopsis
- Cerebral venous thrombosis (CVT) can lead to sudden loss of balance and coordination (vestibulopathy) without significant hearing loss, attributed to reduced blood flow in the inner ear.
- A unique case involved a 69-year-old woman who experienced acute vertigo; MRI revealed a blockage in her brain's venous drainage and bleeding in the inner ear.
- The case emphasizes the need for MRI to differentiate vestibular neuritis from conditions like CVT and highlights that vestibular issues could arise from complications like inner ear bleeding due to CVT.

Eye-Neck Integrated Ultrasound in Idiopathic Intracranial Hypertension and Cerebral Venous Sinus Thrombosis.
Front Neurol
July 2021
Department of Neurology, The First Hospital of Jilin University, Changchun, China.
Article Synopsis
- Researchers explored using eye-neck integrated ultrasound to differentiate between cerebral venous sinus thrombosis (CVST) and idiopathic intracranial hypertension (IIH), as there is no existing screening tool for these conditions.
- They analyzed data from 20 IIH patients, 30 CVST patients, and 40 healthy controls, measuring the optic nerve sheath diameter (ONSD) and blood flow in the internal jugular veins (IJVs).
- Findings showed that a larger ONSD was predictive of IIH, while reduced blood flow volume (BFV) indicated CVST, suggesting this ultrasound method could effectively assess intracranial pressure and differentiate between these two conditions.
