摘要
目的探讨多层螺旋CT血管成像(MSCTA)在肾动脉瘤(renal artery aneurysms,RAA)诊断中的应用价值。资料与方法根据肾动脉局限性膨大1.5倍或以上并与正常肾动脉节段间界限分明诊断RAA,回顾性分析14例RAA患者的MSCTA表现。结果 14例共检出RAA 15个,瘤体大小5 mm×6 mm～26 mm×33 mm。其中2个位于肾动脉主干,11个位于一级分支,2个位于二级及以下分支;1例为多发,其余13例均为单发;8个有明显瘤体钙化,4个可见血栓形成,1例因瘤体破裂伴有肾周积血。结论 MSCTA能为RAA的临床诊断和治疗提供有价值的信息,可作为RAA诊断的首选影像学方法。
Objective To explore diagnostic value of multi-slice spiral CT angiography（MSCTA） in renal artery aneurysms（RAA）.Materials and Methods The MSCTA data of 14 patients with RAA were analyzed retrospectively.The diagnosis of RAA was made based on the standard of renal artery diameter dilated to 1.5 times or above than normal with clear boundary.Results 15 RAAs with the size of 5mm×6mm to 26mm×33mm were detected in 14 subjects.2 cases of RAA were located on renal artery,11 cases on level 1 bifurcation and 2 cases on level 2 or above bifurcations.One lesion was multiple aneurysms and the other 13 lesions were solitary aneurysm.Obvious calcification were showed in 8 cases,visible thrombosis in 4 cases,and perinephric hematoma due to tumor rupture was showed in 1 case.Conclusion MSCTA has valuable in diagnosis and treatment of RAA,and can be prefered as first choice in diagnosis.
