ASO与DMASO的MSCTA影像学表现差异性研究

The differential study of MSCTA findings between arteriosclerosis obliterans and diabetic arteriosclerosis obliterans

目的:探讨动脉硬化性闭塞症(ASO)与糖尿病动脉硬化性闭塞症(DMASO)的MSCTA影像学表现的差异性,以期为两种疾病的鉴别诊断提供客观依据,更好的指导临床诊断与治疗。方法:纳入66例诊断为ASO与DMASO的患者,其中ASO41例,DMASO25例。行MSCTA检查,将获得的动脉期轴位图像数据结合多种后处理图像,对扫描范围内动脉节段的观察指标进行记录及分析。结果:ASO与DMASO的MSCTA影像学表现差异性,与糖尿病动脉硬化性闭塞症相比较,动脉硬化性闭塞症在髂总动脉双侧狭窄、髂外动脉的双侧钙化、髂外动脉单侧增厚、髂内动脉单双侧狭窄及单双侧闭塞、股总动脉单双侧狭窄、股深动脉双侧狭窄及双侧闭塞、动脉单侧狭窄等方面占比重较大。结论:动脉硬化性闭塞症与糖尿病动脉硬化性闭塞症的MSCTA影像学表现存在差异性。研究结果可以为两种疾病的鉴别诊断提供客观依据。

Objectlve：To study the differentiation study of MSCTA findings between arteriosclerosis obliterans and diabetic arteriosclerosis obliterans. In order to offer proofs for the syndrome differentiation and better gnidance for the clinical diagnosis and treatment. Methods： There were total 66 cases which were definitely diagnosed of ASO and DMASO taken MSCTA scans, including 25 cases of DMASO and 41 cases of ASO. The images acquired by post processing with applicable techniques combined with axial ones were analyzed according to the artery segments and observed indexes. Then the data were analyzed by statistics. Results： The differentia study of MSCTA findings between arteriosclerosis obliterans and diabetic arteriosclerosis obliterans demonstonted that compared with DMASO, ASO taken up the most part in vessel stenosis of popliteal artery, calcification of bilateral external iliac artery, wall thickening of unilateral external iliae artery, vessel stenosis and obstruction of internal iliac artery overall, bilateral and unilateral, vessel stenosis of unilateral femoral artery, vessel stenosis and obstruction of bilateral deep femoral artery. Conclusion： There was certain diffrence of MSCTA findings between ASO and DMASO. There were distinguished MSCTA findings between ASO and DMASO. The results could be adopted to offer the proofs for distinguishing the two diseases.
