Figure 6: Example of a platelet-rich clot that is isodense on NCCT.

Figure 6:

(A) An NCCT image of the patient prior to mechanical thrombectomy. There is an absence of a Hyperdense Artery Sign in the left ICA Terminus and M1 branch of the MCA. (B) A digital subtraction angiography (DSA) image of the patient prior to mechanical thrombectomy demonstrating occlusion of the ICA Terminus and MCA. (C) A DSA image of the patient after treatment with mechanical thrombectomy to remove the occlusive clot demonstrating full revascularization (TICI3) in the MCA. (D) is the gross photograph of the retrieved clot after fixation in PFA. (E&F) Low (0.5x) and High (40) magnification image of the MSB stained slide from the clot demonstrating the presence of platelet-rich region (34.6% Platelets, Grey) within the clot.
