Mortality in untreated Stanford type A dissection increases approximately 2.6% per hour during the first 24 h and may reach 47%-55% within 24-48 h. In critically ill patients, point-of-care ultrasound has emerged as a valuable bedside tool, particularly when conventional imaging is delayed or contraindicated. We describe the case of a 43-year-old man with Marfan syndrome, prior ascending aortic replacement with a Dacron graft (without aortic valve replacement), intellectual disability, psychiatric disorders, hypertension, dyslipidemia, hypothyroidism, and a known descending aortic aneurysm. He was transferred from a rehabilitation center to the intensive care unit due to hypotension. A non-contrast thoracic CT scan had been performed in the emergency department prior to ICU admission because of a documented severe allergy to iodinated contrast media. Upon ICU arrival, he was in shock and required mechanical ventilation and vasopressor support. Parasternal windows were not interpretable due to poor acoustic quality; suprasternal and abdominal aortic views were attempted but not feasible. However, apical five- and three-chamber transthoracic views revealed a markedly dilated ascending aorta and a mobile thin intimal flap distal to the aortic valve. Color Doppler demonstrated differential flow patterns consistent with true and false lumens and moderate-to-severe aortic regurgitation. These findings were highly suggestive of Stanford type A aortic dissection. Given the unequivocal transthoracic findings, transesophageal echocardiography was not performed in order to avoid further delay, and the patient was urgently transferred to a cardiac surgery center for definitive management. Clinical outcome after transfer remains unknown.

While FS is traditionally diagnosed clinically, musculoskeletal ultrasound (MSKUS) is emerging as a valuable adjunct tool capable of identifying early-stage structural and vascular changes. This review synthesizes the current evidence on MSKUS's diagnostic utility, highlighting its capacity to visualize characteristic features such as capsular thickening, rotator interval (RI) hypervascularity, and effusion in the long head of the biceps tendon (LHBT) sheath-particularly prominent in early or intermediate disease stages. Although MSKUS is highly operator-dependent and demands substantial training, its integration into clinical assessment may enhance diagnostic precision, particularly when FS is suspected early. As the field advances, combining MSKUS findings with metabolic and inflammatory biomarkers may support a pathophysiological classification of FS, paving the way for more personalized, algorithm-based interventions. In summary, MSKUS provides a safe, accessible, and dynamic modality for detecting capsuloligamentous changes in FS. Its role in early diagnosis, differential screening, treatment monitoring, and future integration with systemic biomarkers supports its growing clinical relevance in both orthopedic and interdisciplinary settings.</p>","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":" ","pages":"943-953"},"PeriodicalIF":1.4,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145504624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
