Giant aneurysms are defined as having a maximal diameter higher than 25mm. The dynamic aspect of giant aneurysms, in particular, is its growth, which was responsible for parenchyma sequellae either due to haemorrhagic complications or a compression of cranial nerves. The treatment of these giant aneurysms was challenging because of its size, the mass effect and the neck diameter. These morphologic conditions required complex endovascular procedures such as remodelling, stenting, using flow diverters. Subsequently, the complex procedures increased the risk of morbidity because of ischemic complications. Despite these procedures, the risk of recurrence was high.
巨大动脉瘤被定义为最大直径超过25毫米。尤其是巨大动脉瘤的动态特征在于其生长，这会因出血性并发症或颅神经受压而导致实质后遗症。由于其大小、占位效应和颈部直径，这些巨大动脉瘤的治疗具有挑战性。这些形态学状况需要诸如重塑、支架置入、使用血流导向装置等复杂的血管内介入操作。随后，由于缺血性并发症，这些复杂操作增加了发病风险。尽管采取了这些操作，复发风险仍然很高。
