It is known that unexpected deaths can occur due to pulmonary thromboembolism (PTE) and that anticoagulation is frequently effective in reducing the possibility of a new embolic event and death. A correlação da fDlate com os resultados de imagem confirma a validade desta nova ferramenta diagnóstica não-invasiva. A fDlate pós-operatória foi de - 0,04, um valor inferior ao valor de corte de 0,12 e foi caracterizada como negativa. A fDlate pré-operatória foi de 0,16 e foi considerada positiva por estar acima do valor de corte de 0,12. O cálculo da fDlate se baseou na capnografia volumétrica e na gasometria arterial de acordo com ERIKSSON et al. O TEP foi diagnosticado por ultrassonografia ecodoppler de membros inferiores, cintilografia pulmonar, tomografia helicoidal computadorizada e arteriografia pulmonar. The agreement of fDlate with the imaging results confirms the validity of this new, noninvasive diagnostic tool.Įste relato de caso apresenta os resultados da fDlate (fração tardia de espaço morto) em um paciente submetido a embolectomia por tromboembolismo pulmonar (TEP). The postoperative fDlate value was - 0.04, which was below 0.12 and was characterized as negative. The preoperative fDlate value was 0.16, which was considered positive for the diagnosis of PTE, as it was higher than the cut-off point of 0.12. The fDlate was calculated based on volumetric capnography as well as on arterial blood gases according to ERIKSSON et al. Pulmonary thromboembolism (PTE) was diagnosed by echo-Doppler ultrasound of the lower limbs, lung scintigraphy, computerized helical tomography and angiography. This report presents data on the late dead space fraction (fDlate) of a patient submitted to surgical pulmonary embolectomy.
