Özet
Our aim was to investigate the role of computed tomography pulmonary angiography (CTPA) in the diagnosis of right ventricular dysfunction (RVD) and massive pulmonary thromboembolism (PTE). We retrospectively involved a total of 61 patients. In CTPAs, pulmonary arterial obstruction index (PAOI), right ventricular/left ventricular diameter ratio (RV/LV), and superior vena cava (SVC) diameters were calculated, followed by echocardiography (ECHO), and clinical results were evaluated based on the reports available. CTPA findings that included PAOI, RV/LV ratio, and SVC diameter were, respectively, 54.9 +/- A 22.7 %, 1.58 +/- A 0.51, and 20.3 +/- A 0.2 mm in patients with RVD on ECHO, whereas corresponding values were, respectively, 37.8 +/- A 24.2 %, 1.32 +/- A 0.47, and 18.4 +/- A 3.3 mm in those without RVD (respectively, p = 0.006, p = 0.038, and p = 0.026). PAOI was 63.3 +/- A 22.0 % in patients among whom massive PTE was detected and 43.1 +/- A 23.9 % in the group without massive PTE (p = 0.01). As for mortality; given an RV/LV ratio > 1.0, this ratio had 100 % sensitivity and 35.6 % specificity, whereas given a PAOI of a parts per thousand yen50 %, sensitivity and specificity were 83.3 % and 57.8 %, respectively. We concluded that in the patients with PTE, PAOI a parts per thousand yen50 % and RV/LV > 1.0 in CTPA could be helpful to demonstrate RVD.
