Correlations of two segmented thrombi with different histological compositions and the respective radiological findings. The upper row demonstrates a red blood cell (RBC)-rich clot (a) that had caused an M1 occlusion as demonstrated by the CTA ((b) occlusion marked by an arrow). In first-run DSA the clot had migrated to the proximal M2 ((c) occlusion marked by an arrow). The lower row shows a non-RBC-rich clot (d) that had caused an MCA occlusion in the middle M1 segment without signs of migration. In CTA (not shown) and first-run DSA the proximal lenticulostriate arteries were uncovered by the thrombus and were apparent ((e) occlusion marked by an arrow). The occlusion site fits very well to the infarct pattern later seen on MRI three days after mechanical thrombectomy, sparing the caudate head and the rostral part of the putamen. Note a focal SAH in the sylvian fissure as an ancillary finding. CTA: computed tomography angiography; DSA: digital subtraction angiography; MCA: middle cerebral artery; MRI: magnetic resonance imaging; SAH: subarachnoid hemorrhage.
