From: Hemodynamic analysis for endovascular treatment in small unruptured intracranial aneurysms: a matched comparison study of flow diverter versus LVIS

Fig. 1

Digital subtraction angiography (DSA) showed a small aneurysm treated with pipeline alone (A, B, C, D arrows). Compared with the preprocedural angiographic image (A), the aneurysm showed intraaneurysmal contrast stasis in the immediately postprocedural angiographic image (B, C arrow). At 6-month follow-up, DSA indicated that the aneurysm was occluded completely (D, arrow). In hemodynamic simulation, compared with preprocedural results (left E, F, G, H), the velocity and WSS of the aneurysm had decreased after treatment (right E, F, G, H). However, the blood flow velocity near the aneurysmal neck remained concentrated (F, arrows), the wall shear stress of the region near the aneurysmal neck remained high (G, arrows). The velocity of the aneurysm neck plane was markedly reduced (H, arrows)
