The Stealth dilation catheter was introduced for the intravascular treatment of two patients with acute and unstable ischemic stroke due to hemodynamically significant stenosis in the one case of the middle cerebral artery and in the other of the vertebral artery. Cerebral perfusion study on the two cases showed a moderately low flow area in the right cerebral hemisphere and in the left cerebellar hemisphere, respectively. Percutaneous transluminal angioplasty (PTA) using the Stealth catheter was conducted. The two cases showed marked improvement in their neurologic state just after PTA with marked increase in cerebral perfusion in the relevant regions.
隐形扩张导管被用于两名急性不稳定缺血性中风患者的血管内治疗，其中一例是大脑中动脉血流动力学显著狭窄，另一例是椎动脉血流动力学显著狭窄。对这两例患者的脑灌注研究分别显示，右侧大脑半球和左侧小脑半球存在中度低血流区域。使用隐形导管进行了经皮腔内血管成形术（PTA）。这两例患者在PTA后神经状态均有显著改善，相关区域的脑灌注显著增加。
