Abstract

Introduction: The aim of this study is to determine the relationship between the Geneva clinical rules, pulmonary artery computed tomography index ratio (PACTOIR) and patient mortality in patients with suspected pulmonary thromboembolism (PTE).

Material and Method: The spiral tomographic pulmonary angiographies of 88 patients were analyzed retrospectively in search of PTE. The Geneva clinical possibility scoring for each patient was also calculated. The exitus patients were investigated.

Results: 37 (42%) of the patients were diagnosed to have PTE, while this diagnosis was sidelined in 51 (58%) of them. While according to the Geneva clinical scoring system 27.2% of the patients had a high clinical possibility, 52.3% had a medium clinical possibility and 20.5% had low possibility for PTE, patients with PTE displayed the clinical risks to be 48.7%, 37.8% and 13.5% respectively. In the groups of clinical possibility classification, the averages of PACTOIR for differentiation analysis was found to be significant (p<0.005). In this study we found that 6 patients had died. In all patients lost due to PTE, there was a higher rate of clinical possibility and high PACTOIR rates.

Conclusion: Pulmonary artery computed tomography obstruction index ratio shows the load of the thrombus thus giving the clinician a good perspective about the prognosis of the patients.
