Multislice computed tomography angiography in the diagnosis of splenic artery aneurysm

Objective: To assess the clinical value of multislice computed tomography angiography (MSCTA) in the diagnosis and treatment planning of splenic artery aneurysm. Methods: Twelve patients with splenic artery aneurysms underwent MSCTA, The axial and 3D reconstruction images including multiplanar reformation (MPR), curved planar reformation (CPR), maximum intensity projection (MIP) and volume rendering (VR) were reviewed. Results: The mean diameter of the 12 aneurysms was 27 mm. MSCTA demonstrated the location, size and morphology of the aneurysms clearly. MSCTA was superior to digital subtraction angiography with 3D display of the aneurysm and its relationship with surrounding structures. The patients were treated by resection of splenic aneurysm, spleen and pancreatic tail (2), resection of splenic aneurysm and reconstruction of splenic artery (2), and endovascular embolization (4). Conclusions: MSCTA is noninvasive and provides accurate 3D anatomic information for diagnosis and treatment planning of splenic artery aneurysms. (authors)
