Multicenter Study
A detailed evaluation of patients with acute pulmonary embolism and low- or very-low-probability lung scan interpretations.
To determine the clinical characteristics of patients with pulmonary embolism (PE) and low- or very-low-probability ventilation-perfusion lung scan interpretations. ⋯ Patients with a history of immobilization, trauma to the lower extremities, recent surgery, or central venous instrumentation were more likely to have false-negative lung scan interpretations. Therefore, this population warrants special attention when deciding on the need for peripheral venous studies or angiography in patients with low- or very-low-probability lung scan interpretation.
