PULMONER TROMBOEMBOLİ TANISINDA SPİRAL BİLGİSAYARLI TOMOGRAFİ

Spiral computed tomography in the diagnosis of pulmonary thromboembolism. Pulmonary embolism (PE) İs a common dİsease with hİgh morbidity and mortality. The aim of the study was to compare the accuracy of spiral computed tomography (CT) widı ventilation-perfusion scintigraphy for the diagnose of pulmonary embolism. Eighteen patients (9 female, 9 male, mean age 44.4±14.3 year) were İncluded. CT İmages for the patients were viewed at settings for pulmonary vasculature, lung parenchyma and pleural pathologies. The presence of clot in the main and segmental pulmonary arteries was observed in 7 (39%) patients. In 6 patients (33%), the İndirect sign of pulmonary thromboembolism, localized vasculary enlargement was observed. In pulmonary vessel, there were no clot sign in 5 patients (28%). Parenchymal infiltrates were seen togetlıer in 3 of them. Minimal pleural effuision was seen 13 patients (72%). Four of the 5 patients underwent CT scan in which did not have clot formatİon in pulmonary artery vasculature had mediai lobe parenchymal consolidatİon. Ventilation- perfusion lung seans were found as hİgh probabiüty in 10 patients. Clot formation findings on spiral CT were found in 7 patients (70%) with high probabity scintigraphic scan for pulmonary embolism. In addition, 6 of the 8 patients (75%) with low or moderate V/Q scan also had findings of clot fİndİngs on spiral CT. It was coneluded that, spiral CT and V/Q scintigraphy when combined havc sİgnifİcant value for diagnosing of acute PE.
