Computed Tomography Angiography in Diagnosis and Treatment of Splenic Artery Aneurysm

Splenic artery aneurysm, without obvious symptoms, is a direct threat to the patient＇s life, once it ruptures as hemorrhagic shock.Imaging examinations have been the main diagnostic methods of splenic artery aneurysm, including ultrasound, computed tomography （CT）, magnetic resonance imaging, and digital subtraction angiography （DSA）.Although various inspective methods have their own advantages and disadvantages, abdominal CT examination is the most comprehensively applied method in clinical settings.The representative images of splenic artery aneurysm from a relatively large number of patients examined by CT are presented in this study.
