This case illustrates rapid aneurysm enlargement, presumably due to altered hemodynamics resulting from endovascular treatment of aneurysms on the same artery. We postulate that increased hemodynamic force directed to the inflow zone of the posterior communicating artery aneurysm was caused by the treatment of the two ophthalmic artery aneurysms. Originally, many of the flow vectors may have been directed into the larger ophthalmic segment aneurysm, located on the outside of the curve of the internal carotid artery. After treatment, flow may have been directed more smoothly around the carotid siphon and into the posterior communicating artery aneurysm.
该病例显示了动脉瘤的快速增大，推测是由于对同一动脉上的动脉瘤进行血管内治疗导致血流动力学改变所致。我们推测，对两个眼动脉动脉瘤的治疗导致了向后交通动脉瘤流入区的血流动力学力增加。最初，许多血流向量可能指向位于颈内动脉曲线外侧的较大的眼段动脉瘤。治疗后，血流可能更顺畅地绕过颈动脉虹吸部并流入后交通动脉瘤。
