Abstract:
50%,0-patent lumen.Those legs with dominant crural arterial lesion (gradeⅠ,Ⅱor Ⅲ) on at least one segments and without femoropopliteal arterial obstructions were selected.Results Totally 75 legs were involved.There were 53 legs( 70.7%) with only 1 main artery damaged,14 legs( 18.7%) with 2 main arteries damaged,and 8 legs( 10.6%) with all 3 main arteries damaged.Among the 5 arterial segments,the anterior tibial arterial lesions were found most frequently ( 73.3%,55/75),in which the segmental occlusion (gradeⅡ) was the most common type.The peroneal arterial lesions appeared least ( 20.0%,15/75).In the damaged main arteries,1/3 anterior tibial-dorsal arteries and 1/5 posterior tibial arteries had greatly improved distal vascularity compared with their proximal and middle portion,owing to the collateral arteries around the ankle.Statistical analysis showed that there was close relationship between the blood flow damage of the distal portion of the posterior tibial arterial segments (medial trans-ankle flow) and the peroneal artery with the clinical ischemic manifestations.Conclusions The dominant occlusive crural arterial lesions and the collateral arteries can be well imaged and diagnosed by color Doppler ultrasonography,which is helpful in providing accurate information of the blood supply of the distal part of the lower extremity.
