OBJECTIVES: In the last 20 years, with the use of computed tomography (CT) angiography, the number of patients diagnosed with pulmonary thromboembolism (PTE) has increased. At the same time, data show that pulmonary embolism mortality has also reduced in this duration.


MATERIAL AND METHODS: In this study, we analyzed records of patients with PTE (using ICD’s) in the hospital automation system from 2001 to 2013. Data regarding age, sex, date of diagnosis, diagnosis of cancer, hemodynamic status, initial and maintenance treatment, hospital length of stay, and hospital mortality were recorded. Primary endpoints  of the study were hospital length of stay and all-cause hospital mortality.


RESULTS: The total number of patients included in the study was 1185. The median age was 61 years in 2001 and 71 years in 2013. The number of patients who were diagnosed using CT increased from 10% to 92.8%. Between 2001 and 2013, the number of patients diagnosed with PTE increased, and of all patients with PTE, 13.7% was diagnosed in 2009. The hospital length of stay of 13 days declined to 9 days. The use of a vena cava filter in 2007 was 1.1% and that in 2013 was 4.6%. Mortality rate was 15%, however hospital mortality did not significantly differ over the years but varied between 9.4% and 18.8%. Increased use of thrombolytics in patients with massive PTE has been observed over the years. Massive PTE ratio in 2006 was 8.5% and thrombolytic use was 5.8%, however in 2013, these ratios were 2.6%, 6% respectively (p=0.017).


CONCLUSION: Finally, despite the increased number of patients diagnosed with PTE over the years, the mortality rate was not observed to have changed from 2001 to 2013.
