Which statement best describes mTICI grade 3?

Which statement best describes mTICI grade 3?

• A. No reperfusion
• B. Flow beyond occlusion with distal branch reperfusion
• C. Reperfusion beyond occlusion with distal branches fully reperfused
• D. Complete reperfusion of downstream target arterial region and distal branches

Answer: (D)

The main idea here is what complete reperfusion looks like on the mTICI scale after thrombectomy. The modified scale runs from no perfusion to full perfusion of the downstream territory. Grade 3 means complete reperfusion of the entire downstream arterial region that was at risk, including all distal branches. In other words, flow is restored throughout the target territory with no remaining perfused tissue outside the desired area still showing blockage. This is more than just perfusion beyond the occlusion or partial reperfusion; it reflects full restoration of flow to the whole downstream vascular bed. Other descriptions fit partial or absent reperfusion, but none indicate the entire territory and its distal branches are fully perfused, which is what grade 3 conveys.
