An increased total stent length (TSL) might be associated with a higher risk of clinical events; however, in patients with multivessel disease (MVD), a considerable TSL is often required. In patients presenting with acute coronary syndrome and MVD, immediate complete revascularization was associated with shorter TSL in the BIOVASC (Immediate versus staged complete revascularisation in patients presenting with acute coronary syndrome and multivessel coronary disease) Trial. This is a subanalysis of the BIOVASC trial comparing clinical outcomes in patients with either <60 or ≥60 mm TSL.

Low Diagnostic Accuracy of Transthoracic Ultrasound for the Assessment of Spontaneous Pneumothorax in the Emergency Setting: A Multicentric Study.

J Clin Med

August 2024

Unit of Interventional and Diagnostic Ultrasound of Internal Medicine, Fondazione IRCCS Casa Sollievo della Sofferenza, 71013 San Giovanni Rotondo, Italy.

Article Synopsis
  • Pneumothorax (PNX) is frequent in emergency departments and needs quick diagnosis and treatment; this study examined how well transthoracic ultrasounds (TUSs) identify spontaneous PNX.
  • 637 adult patients with chest pain and breathing issues from four Italian hospitals were included, and TUS results were compared to chest CT scans to determine accuracy metrics like sensitivity and specificity.
  • TUS accurately identified 89.2% of spontaneous PNX cases but had low specificity (43.8%), indicating it shouldn't be the sole diagnostic tool; TUS results should be corroborated with a chest X-ray or CT scan for proper patient management.
