Pulmonary embolism

PE, a common and serious pulmonary problem, most often results as a complication of DVT in the lower extremities. There are no specific symptoms or signs that allow a clinical diagnosis of PE. The best approach to the diagnosis is controversial and is at least partially dependent on the diagnostic capabilities and expertise available at a given hospital. Pulmonary arteriography is the definitive diagnostic test and should be considered in patients with results of less-than-high probability V-Q scans, those at high risk of bleeding complications with anticoagulation therapy, and those considered candidates for thrombolytic therapy.
