PURPOSE
To review our experience with intracranial angioplasty, including the complications we encountered.
METHODS
During a 3-year period, from 1993 to 1996, 10 patients had intracranial percutaneous transluminal angioplasty (PTA). The stenosed vessels included three internal carotid arteries, one middle cerebral artery, one basilar artery, and five vertebral arteries. Stenosis in all patients was 75%, or greater. PTA was technically successful in eight patients; in two patients it could not be performed owing to inability to traverse the stenosed area.
RESULTS
Two patients had successful and uneventful PTA. Five patients had vasospasm, which resolved with local vasodilators in two and with repeat PTA in one. Vasospasm led to stroke in two patients. Compromise of perforating vessels and arterial dissection were associated with stroke in two patients.
CONCLUSION
Intracranial PTA is technically feasible but associated with risks related to vasospasm, arterial trauma, and compromise of perforating vessels.
目的
回顾我们在颅内血管成形术方面的经验，包括我们所遇到的并发症。
方法
在1993年至1996年的3年期间，10例患者接受了颅内经皮腔内血管成形术（PTA）。狭窄血管包括3条颈内动脉、1条大脑中动脉、1条基底动脉和5条椎动脉。所有患者的狭窄程度均为75%或更高。8例患者的PTA技术成功；2例患者因无法穿过狭窄区域而未能进行该操作。
结果
2例患者PTA成功且过程顺利。5例患者发生血管痉挛，其中2例通过局部使用血管扩张剂缓解，1例通过重复PTA缓解。血管痉挛导致2例患者发生卒中。穿支血管受损和动脉夹层与2例患者的卒中有关。
结论
颅内PTA在技术上是可行的，但与血管痉挛、动脉损伤和穿支血管受损相关的风险有关。
