Abstract

Objective To Evaluation of diagnosis and thrombolysis effect on pulmonary embolism by 256 slice spiral computed Tomography. Methods 33 patients were analyzed with pulmonary embolism 256 slice spiral CT pulmonary angiography, including 18 cases who were reviewed after thrombolytic therapy. Results 215 embolism pulmonary artery were detected in the group of 33 patients.They located in respectively the pulmonary artery: left/right pulmonary artery: lobe pulmonary artery: period of pulmonary artery branch: the period of the pulmonary artery = 3:35:40:114-23. Meanwhile, there were 25 cases of bilateral pulmonary embolism, 8 cases of unilateral pulmonary embolism, and only 18 cases turned up the presence of pulmonary intravascular filling defect to dissolution or disappear in some extent after thrombolytic therapy. Conclusion MSCTA can be a kind of fast safe and effective inspection method to clearly show the shape, size and range which are formed by endovascular thrombosis embolism, and has important clinical value to diagnose of PE guiding treatment and judging curative effect.
