The Relative Study Of Arteriosclerosis Obliterans Between Traditional Chinese Medicine Type Of Syndrome And MSCTA Findings

Objective: To study the correlation of ASO between TCM type of syndrome and MSCTA findings. In order to offer proofs for the syndrome differentiation and better guide the clinical diagnosis and treatment. Methods: There were total 45 cases which were definitely diagnosed of ASO and taken MSCTA scans, including 27 cases of blood stasis type and 18 ones of damp-heat invading lower Jiao type. 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 correlation between TCM type of syndrome and MSCTA findings: The findings mainly appeared in damp-heat invading lower Jiao type as follows: calcification of bilateral external iliac artery, wall thickening of bilateral external iliac artery and bilateral common femoral artery, vessel stenosis of common iliac artery, vessel stenosis of deep femoral artery overall and bilateral, vessel stenosis of popliteal artery, vessel obstruction of internal iliac artery overall and bilateral, vessel obstruction of deep femoral artery overall and unilateral, filling defect of abdominal aorta, multiple calcification of deep femoral artery. There were seldom such findings displayed on images of blood stasis type. Vessel stenosis of unilateral internal iliac artery was showed on images of blood stasis type, while it was not for damp-heat invading lower Jiao type. Conclusion: There was certain correlation between TCM type of syndrome and MSCTA findings. There were distinguished MSCTA findings between blood stasis type and damp-heat invading lower Jiao type. The results could be adopted to offer the proofs for TCM syndrome differentiation.
