Deep venous thrombosis (DVT) probably accounts for the majority of detached thrombus that becomes lodged in the pulmonary arteries giving rise to pulmonary embolism (PE).
Negative highly sensitive D-dimer test with a low or indeterminate pretest probability essentially excludes VTE.
High-risk or massive PE is defined by the American Heart Association as ‘sustained hypotension (systolic blood pressure of <90 mmHg for more than 15 min) or the requirement for inotropes or signs of shock’.
Thrombolysis is only recommended for patients who have a diagnosis of massive PE.
