Blood blister-like aneurysms in Tibetans: A retrospective observational study

Blood blister-like aneurysms (BLAs) are a high-risk neurovascular disease with high morbidity and mortality. First described in 1988, BLAs account for only 0.3%-6.6% of all intracranial aneurysms [8,11,12,17]. Their typical characteristics are fully understood as a thin hemispherical wall with a predilection to a non-branching dorsal part of the internal carotid artery (ICA) [18,27]. Due to their extremely fragile thin walls [17,28,29], severe perioperative rebleeding (33% –80%) has been a great challenge for neurosurgeons [22].
