Key result
Selective pulmonary digital subtraction angiography provided excellent or adequate image quality in 98.5% of patients, with only 0.9% (95% CI 0.0-4.2%) of negative-scan patients having possible PE.
Why the study?
Is selective pulmonary digital subtraction angiography with a flow-directed catheter safe and clinically valid for diagnosing suspected acute pulmonary embolism?
Observational (n=211)
Is selective pulmonary digital subtraction angiography with a flow-directed catheter safe and clinically valid for diagnosing suspected acute pulmonary embolism?
Pulmonary DSA with a flow-directed catheter is a safe procedure that provides high-quality images and allows for the safe withholding of anticoagulation when results are negative.
No takes yet. Share an insight, caveat, or question.
May support withholding anticoagulation after negative selective pulmonary DSA; leaves open need for prospective validation before practice change.
Rooij et al. (1995) conducted an observational in Suspected acute pulmonary embolism (n=211). Selective pulmonary digital subtraction angiography (DSA) with a flow-directed catheter was evaluated on Possible PE after negative DSA (95% CI 0.0-4.2). Selective pulmonary digital subtraction angiography provided excellent or adequate image quality in 98.5% of patients, with only 0.9% (95% CI 0.0-4.2%) of negative-scan patients having possible PE.
