Objective: To study on lesion characteristic and treatment of atherosclerosis occlusion (ASO).
Methods: Collect and analysis 413 patients, 778 lower extremities digital subtraction angiography (DSA) from Jan. 1, 1996 to Dec. 31, 2007 in our hospital.
Results: Left 220 (28.3%), right 208 (26.7%), both 350 (45.0%); type I 65 (8.4%), type II 194 (24.9%), type III 519 (66.6%); single level 135 (17.4%), multilevel 643 (82.6%); profound lesions stenosis 82 (10.5%), occlusion 16 (2.1%).
Conclusions: Multilevel lesions are the main characteristic in all cases (about 4/5); we should design individual treatment dependent on lesion characteristic. Endovascular intervention and bypass reconstruction is main treatment for ASO.
