Figures

Figure 1
Figure 1
Example of thrombolysis in cerebral infarction (TICI) 0 and TICI 2b. Top, Anteroposterior (first 2 boxes) and lateral (last 2 boxes) in an early arterial and late capillary phases depicting TICI 0 at baseline. Bottom, Same phases depicting TICI 2b after intra-arterial therapy. Black arrow indicating the target arterial lesion (TAL): middle cerebral artery/M1 horizontal segment occlusion (TAL) distal to the lenticulostriate (LS). Black half circles approximate the target downstream territory (TDT; the presumed area supplied by the TAL).
Figure 2
Figure 2
Example of thrombolysis in cerebral infarction (TICI) 1 and TICI 3. Top, Anteroposterior (left) and lateral (right) in an early arterial and late capillary phases depicting TICI 1 at baseline. Bottom, Same phases depicting TICI 3 after intraarterial therapy. Black arrow indicating the target arterial lesion (TAL): middle cerebral artery/M1 horizontal segment occlusion (TAL) distal to the lenticulostriate (LS). Black half circles approximate the target downstream territory (TDT; the presumed area supplied by the TAL). Ischemic arteriovenous shunting is noted with opacification of straight sinus (right bottom corner).

Figure 3
Example of thrombolysis in cerebral infarction (TICI) 0 and TICI 2a (compared with TICI 2b and 3 above). Top, Anteroposterior (first 2 boxes) and lateral (last 2 boxes) in an early arterial and late capillary phases depicting TICI 0 at baseline. Bottom, Same phases depicting TICI 2a after intra-arterial therapy. Black arrow indicating the target arterial lesion (TAL): middle cerebral artery/M1 horizontal segment occlusion (TAL) distal to the lenticulostriate (LS). Black half circles approximate the target downstream territory (TDT; the presumed area supplied by the TAL).

Figure 5
Example of downstream territory (TDT) for an ICA occlusion with pre–intra-arterial therapy (IAT) data from CT angiogram showing cross-filling from the contralateral anterior cerebral artery. Top, Anteroposterior (first 2 boxes) and lateral (last 2 boxes) in an early arterial and late capillary phases depicting thrombolysis in cerebral infarction (TICI) 0 at baseline. Bottom, Same phases depicting TICI 3 after IAT. Black arrow indicating the target arterial lesion (TAL): Distal ICA proximal to the ophthalmic artery. Black half circles approximate the target downstream territory (TDT; the presumed area supplied by the TAL). Early ischemic arteriovenous shunting is noted in the right lower corner.
