The V-line: a sonographic aid for the confirmation of pleural fluid
نویسندگان
چکیده
BACKGROUND Ultrasound is being used increasingly to diagnose pathological free fluid accumulation at the bedside. In addition to the detection of peritoneal and pericardial fluid, point-of-care ultrasound allows rapid bedside diagnosis of pleural fluid. FINDINGS In this short report, we describe the sonographic observation of the vertebral or 'V-line' to help confirm the presence of pleural fluid in the supine patient. The V-line sign is a result of the fluid acting as an acoustic window to enable visualization of vertebral bodies and posterior thoracic wall, thus confirming the presence of pleural fluid. CONCLUSIONS The V-line is a useful sonographic sign to aid the diagnosis of pleural free fluid.
