TY - JOUR T1 - Delayed collapse of flow diverter due to acute severe vasospasm: another concern for flow diversion in ruptured aneurysms JF - Journal of NeuroInterventional Surgery JO - J NeuroIntervent Surg SP - 176 LP - 177 DO - 10.1136/neurintsurg-2022-018984 VL - 15 IS - 2 AU - Ajay Kumar AU - Neha Choudhary AU - Anuj Prabhakar AU - Vikas Bhatia Y1 - 2023/02/01 UR - http://jnis.bmj.com/content/15/2/176.abstract N2 - In vivo morphological change of flow diverter stents (FDS) is a known phenomenon and can be seen secondary to various device- and vasculature-related factors such as improper sizing of the device, twisting of the device in tortuous anatomy, insufficient proximal landing zone, and insufficient chronic resistive force of the stent, etc. However, we have encountered a case where severe vasospasm due to aneurysmal subarachnoid hemorrhage led to the collapse of the proximal end of the FDS. Development of vasospasm and consequent possible failure of the device should be taken into consideration when planning flow diversion in ruptured aneurysms. ER -
