The basic disorder might be vascular dysfunction leading to local vasospasm and to systemic hypotension. 其基本的改變可能是血管的功能障礙導致局部的血管痙攣和低血壓。
Furthermore, ECs obtained from these vascular malformations can be used as an experimental model to study SAH-induced vasoconstriction. 此外，這些來源于畸形血管的內皮細胞可作為研究蛛網膜下腔出血引發血管收縮的實驗模型。
