Relationship between computerized tomographic pulmonary angiography findings with clinical indices and scoring parametres in pulmonary embolism

Abstract

Pulmonary embolism is an important cause of mortality and morbidity. We aimed to evaluate relationship between computerized tomographic pulmonary angiography findings with clinical presentation and clinical scoring parameters. We categorized pulmonary embolism locations as subsegmental, segmental, lobar and main branches depending to radiologic findings and calculate Wells and Pulmonary Embolism Severity Index (PESI) scores in patients diagnosed with pulmonary embolism in emergency department , outpatient clinics, wards or intensive care units. Patients were followed for 30 days mortality. Totally 218 patients (M/F:114/104, mean age: 52,4 years) were included in the study. According to Wells scoring there were 22 patients in low probability group, 190 in moderate probability group and 6 in high probability group. According to PESI score there were 27(12%) in categoryI, 33(%15) in categoryII, 43(%20) patients categoryIII, 46(%21) patients in categoryV and 69((%32) in categoryIV. Wells and PESI scores did not show any significant difference according to localization of pulmonary embolism. Wells and PESI scores have positive correlation (r:0,232, p We could not show any relation between localization of pulmonary embolism and clinical scores but mortality and presence of pleural effusion were common in PESI categoryV. PESI scoring is highly important for clinical follow up in pulmonary embolism patients.
