Why DUSK

Distal and medium vessel occlusions account for 25 to 40% of ischemic strokes, yet there is no universal treatment strategy. Deficits can look mild on a scale and still be disabling, while thrombectomy in smaller, more distal arteries carries its own risk. DUSK is designed to settle the question with randomized evidence.
