Abstract:

Purpose: This clinical study aimed at determining whether mean platelet volume values were useful in predicting embolic load by comparing the values of patients diagnosed with pulmonary thromboembolism with pulmonary arterial computed tomography obstruction index. Material and Methods: This retrospective study enrolled 120 inpatients with pulmonary thromboembolism diagnosis in emergency service. Patients’ mean platelet volume, Troponin-I, D-dimer values, arterial blood gases, chest radiographs, electrocardiograms, echocardiograms and venous doppler ultrasound findings were recorded. Moreover, pulmonary arterial computed tomography obstruction index for each case was calculated by extracting data from patients’ computed tomography angiographies. Results: There was a statistically significant difference particularly between pulmonary arterial computed tomography obstruction index values of the cases having mean platelet volume value < 8.5fl and mean platelet volume value > 8.5fl (25.0 and 45.0). Pulmonary arterial pressure of the group with mean platelet volume level > 8.5 was found significantly higher compared to the group with mean platelet volume level < 8.5fl. Conclusions: Usefulness of correlation between mean platelet volume and pulmonary arterial computed tomography obstruction index in assessing the severity of embolism is unclear.
