经皮腔内血管成形术(PTA)目前正用于治疗主动脉上部动脉粥样硬化,微球囊导管技术的发展使得颅内动脉甚至闭塞血管的PTA成为可能。经皮腔内脑血管成形术(PTCBA)的长期疗效受血管再狭窄的限制,症状的复发发生于血管再狭窄之后,但至今尚未见到关于PTCBA术后序列脑血管造影的随访报道。作者探讨了PTCBA术后首次血管造影的最佳时机、血管再狭窄率以及预告PTCBA成功及低血管再狭窄发生率的血管损伤特点。
Percutaneous transluminal angioplasty (PTA) is currently being used to treat atherosclerosis of the aorta. The development of microcapillary catheterization has made PTA of intracranial arteries and even occluded blood vessels possible. Long-term efficacy of percutaneous transluminal cerebral angioplasty (PTCBA) is limited by restenosis, and recurrence of symptoms occurs after restenosis. However, up to now, no follow-up reports of sequential cerebral angiography have been reported. The authors explored the best timing of first angiography after PTCBA, the rate of vascular restenosis, and the characteristics of vascular lesions that predictor PTCBA success and low rates of vascular restenosis.
