Abstract
Pulmonary thrombus emboli (PTE) have a wide clinical spectrum, from asymptomatic small PTE to life-threatening one, which may cause cardiogenic shock. It is classified as acute/chronic and massive/sub massive. PTE risk factors and relative causes to elevate its mortality are present in this review article. At last, we have a brief recommendation for treatment. There are several diagnosing test such as D-dimer, echocardiography, electrocardiography, brain natriuretic peptide, laboratory tests, chest X-ray, ultrasound, and pulmonary angiography which are different in specificity and sensitivity. Finally, in the diagnostic approach, we explain relative studies to Wells rule, Geneva rule, pulmonary embolism (PE) severity index, and PE rule out criteria.
