Giant intracranial aneurysms represent a very challenging aspect of aneurysmal pathophysiology with very high mortality and morbidity if left untreated. Their variety in clinical presentation (subarachnoid hemorrhage, cranial nerve palsy, etc.) and pathological and imaging properties (location, anatomy, presence of collateral circulation) pose serious questions regarding the best treatment option. Admirable advances have been achieved in surgical techniques, while endovascular modalities with flow diversion techniques have become widely used. However, there is still lack of data regarding whether a single endovascular technique can be the universal treatment for such cases. In this review, we aim to summarize the current funds of knowledge concerning giant intracranial aneurysms and the role of endovascular management in their treatment.

探索巨大动脉瘤血管内治疗的最新发现：综述

巨大颅内动脉瘤代表了动脉瘤病理生理学中非常具有挑战性的一个方面，如果不及时治疗，死亡率和发病率非常高。它们的临床表现（蛛网膜下腔出血、颅神经麻痹等）以及病理和影像学特性（位置、解剖结构、侧支循环的存在）各不相同，对最佳治疗选择提出了严重的问题。外科技术取得了令人钦佩的进步，同时采用血流改道技术的血管内治疗方式也得到了广泛应用。然而，目前仍缺乏关于单一血管内技术是否可以成为此类病例的通用治疗方法的数据。在这篇综述中，我们的目的是总结当前有关巨大颅内动脉瘤的知识以及血管内治疗在其治疗中的作用。
