@sarkarsatarupa The hallmark angiographic findings in patients with TAO are nonatherosclerotic, segmental occlusive lesions of the small and medium-sized vessels (eg, digital, palmar, plantar, tibial, peroneal, radial, and ulnar arteries) with formation of distinctive small collateral vessels around areas of occlusion, known as corkscrew collaterals. These corkscrew collaterals represent dilated vasa vasorum of the occluded arteries, which are now serving to provide distal perfusion, albeit at significantly higher resistance than the native vasculature.
