Abstract:
Objective To explore the application value of triggered angiography non-contrast enhanced (TRANCE) technology in diagnosing lower limb arterial occlusive disease.Methods Totally 22 lower limb arterial occlusive disease patients were randomly selected,and then underwent TRANCE and DSA examinations.The arteries from the abdomen to the lower limb were divided into abdominal aorta,common iliac artery,external iliac artery,internal iliac artery,superficial femoral artery,deep femoral artery,popliteal artery,anterior tibial artery,posterior tibial artery and peroneal artery.Totally 337 sections displayed clearly were chosen to go through examinations by TRANCE and DSA.Results Of the 337 sections there were 312 ones with the same stenoses found by TRANCE and DSA,TRANCE found 16 sections with worse stenoses and 9 milder ones than by DSA.There were 153 sections with the same moderate stenoses (≥50％) displayed by TRANCE and DSA;Of the 153 sections,there were 15 ones with worse stenoses and 6 ones with milder stenoses found by TRANCE than by DSA.Kappa value of the two methods was 0.905.Conclusion TRANCE technology is a non-invasive,safe and nonradiative diagnosing method for the lower limb arterial occlusive disease.
