Four women are described with stenoses of the feeding arteries to cerebral arteriovenous malformations. These stenoses were hemodynamically significant in that the nidus malformations filled late in the arterial phase of angiography and the draining veins did not fill much earlier than the usual venous phase. In two of these patients, who were referred for possible embolization, the stenosis served as an impediment to balloon navigation in the feeding vessel in one and served as a partial contraindication to embolization in the other. It is possible that if these stenoses progress, they may lead to thrombosis of the arteriovenous malformations.
本文描述了4例患有脑动静脉畸形供血动脉狭窄的女性患者。这些狭窄在血流动力学上具有重要意义，因为畸形病灶在血管造影的动脉期晚期才显影，且引流静脉的显影时间并不比正常静脉期早很多。在其中2例因可能需要进行栓塞治疗而前来就诊的患者中，1例患者的狭窄阻碍了球囊在供血血管中的导航，另1例患者的狭窄则成为栓塞治疗的部分禁忌证。如果这些狭窄继续发展，有可能导致动静脉畸形发生血栓形成。
