Pulmonary thromboembolism (PTE) is a clinical condition that can result in sudden death. Computed tomography pulmonary angiography (CTPA) the most sensitive imaging technique for diagnosis of PTE. Filling defects veins, which be identified areas adjacent to PTE, have been named 'pulmonary vein sign' (PVS).The aim our study determine frequency, sensitivity and specificity PVS due decreased venous drainage affected area PTE patients.Patients who were admitted emergency department suspicion underwent CTPA evaluated retrospectively. The group consisted patients had an arterial filling defect on diagnosed with control no CTPA.This included 286 mean age 62(20-94) years. was detected 51(32.7%) 15(11.5%) group. 32.69%, 88.46%, positive predictive value 77.27% negative 52.27% significantly more common having bilateral arteries or main arteries.Despite low sensitivity, presence radiographic marker high To use practice, there need studies large numbers patients.
