A ruptured brain arteriovenous malformation (bAVM) presenting with a hematoma may have unseen parts of the shunts in diagnostic angiography in the acute phase, which may lead to innate incomplete evaluation for the whole angioarchitecture of the bAVM. Even though it is generally accepted that the nidus of a ruptured bAVM may be underestimated in angiography during the acute phase due to hematoma compression, documentation of the underestimated parts has not been described in the literature. The authors report 2 cases of ruptured bAVMs in which the obscured segments were cast with liquid embolic material, which suggests a potential presence of obscured segments in bAVMs.
伴有血肿的破裂脑动静脉畸形（bAVM）在急性期诊断性血管造影中可能存在分流的隐匿部分，这可能导致对bAVM整个血管结构的先天性评估不完整。尽管一般认为，由于血肿压迫，破裂bAVM的病灶在急性期血管造影中可能被低估，但文献中尚未描述被低估部分的记录情况。作者报告了2例破裂bAVM病例，其中用液体栓塞材料对隐匿段进行了铸型，这提示bAVM中可能存在隐匿段。
