Investigating The Prognostic Value Of CT Angiography Criteria In Patients With Acute Pulmonary Thromboembolism

Background: Today, knowing the prognosis of PTE patients is of particular importance, because currently some of these patients can be treated on an outpatient basis, as well as determining the assignment of these patients in the emergency medicine service according to the prognosis of these patients helps a lot in survival. These patients will also reduce costs. Methods: The present study is a longitudinal and retrospective study for all patients hospitalized in Qaem and Imam Reza emergency rooms between ۲۰۱۷ and ۲۰۲۳, who were over ۱۸ years old and were candidates for CT angiography of the lung according to the standard protocol, and they had acute embolism. In CT angiography it was diagnosed by the radiologist, it was considered. Qualitative and quantitative imaging criteria were evaluated. Results: No statistically significant relationship was found between survival status and gender, presence of DVT, history of smoking and history of retplase injection (P>۰.۰۵). There was a significant difference in the systolic and diastolic blood pressure of patients in the two groups, and in the improved group, blood pressure was lower, but no significant difference was observed in the breathing rate and heart rate (P>۰.۰۵). Adjusted for age, sex, systolic and diastolic blood pressure, having a higher ratio of the maximum longitudinal and transverse diameters of the right to left ventricle, protrusion (Bow) of the interventricular septum and having an embolism at the fourth level and age over ۶۵ years with a higher chance of death was associated (P<۰.۰۵). Conclusion: The results indicated that CT angiography criteria have predictive value in patients with acute pulmonary thromboembolism.
