摘要
pulmonary thromboembolism is a common condition. its diagnosis usually requires pulmonary scintigraphy, computed angiotomography, pulmonary arteriography and, in order to rule out other diagnoses, the measurement of d-dimer levels. due to the fact that these diagnostic methods are not available in most brazilian hospitals, the validation of other diagnostic techniques is of fundamental importance. we describe a case of a woman with chronic pulmonary hypertension who experienced a pulmonary thromboembolism event. pulmonary scintigraphy, computed angiotomography and pulmonary arteriography were used in the diagnosis. the d-dimer test result was positive. volumetric capnography was performed at admission and after treatment. the values obtained were compared with the imaging test results.
