ABSTRACT
Objective To estimate the value of MSCTA in the diagnosis of subclavian arterial stenosis.Methods 10 patients with suspected subclavian steal syndrome which causes subclavian artery stenosis underwent MSCTA, the contrast medium was Iohexol 80~90 ml, the flow rate was 3~4 ml/s with sure-star techniques,excretory-phase images were transferred to the workstation and shaded volume rendering (VR),multiplanar reconstruction(MPR),and curved planar reconstruction (CPR) were performed.The left subclavian artery was divided into proximal and distals by openning of left vertebral arteries. Results The narrowing positions6 cases were in proximal and 4 cases were in distal of subclavian artery.6 cases were focal stenosis,4 cases were multiple stenosis and totally 14 focus.The extent of stenosis was 0.8~2.0 cm,10 cases were ≤1 cm and 4 cases were 1.1~20 cm.The degree of stenosis included 7 cases ≤50%,3 cases in 50%~70%.The results was same comparing with that of DSA.Conclusion MSCTA plays an important role in diagnosing subclavian arterial stenosis.
