The length of a clot depends on pial collateral status, and the branching pattern of arteries (angio-architecture) around the original clot. Panel (a) shows normal internal carotid artery and its branching vessels. (b) is the explanation of the sympoles. We think it is a self-explanatory. Panels (c-f) show varying clot lengths depending on pial collateral status and angio-architecture around the original clot. Panel c shows small clot with minimal stasis due to good collaterals and efficient angio-architecture. Panel (d) shows longer overall clot with good collaterals but inefficient angio-architecture. Panel (e) shows long clot due to poor collaterals. Panel (f) shows a very long clot because of poor collaterals and inefficient angio-architecture. Adapted from Qazi et al. 2015 [10]
