Fig. 2. Wall shear stress (WSS) of paired CFD virtual models before (left) and after recurrence (right). The round circle indicates the cross-sectional area of the aneurysm neck at the time of the coil embolization. Note the red color of the high WSS in the round circle of the neck. Recanalization developed at the site which corresponds to the high wall shear stress. (A) Case 1. A 48-year-old man with an aneurysm at basilar tip. (B) Case 2. A 64-year-old woman with an aneurysm at anterior communicating artery. (C) Case 3. A 44-year-old woman with an aneurysm at the origin of posterior communicating artery (D) Case 4. A 57-year-old woman with an aneurysm at the origin of posterior communicating artery (E) Case 5. A 37-year-old woman with an aneurysm at the paraclinoid internal carotid artery.
