Percutaneous Transluminal Angioplasty (PTA) is applied to supra-aortic arteries. Although first follow-up angiography after coronary angioplasty is usually undergone three or four months later, there are few reports of follow-up angiography after PTA of supraaortic arteries. Because of this, we performed follow-up angiography three months after successful PTA on eight cases of stenosis in seven patients. Although no symptom due to restenosis occurred, it was shown to have occurred in one of four cases of internal carotid arterial stenosis. It was a case of ostial stenosis of a left common carotid artery. Restenosis occurred in neither two cases of subclavian arterial stenosis, nor in a case of left middle cerebral arterial stenosis. The overall restenosis rate was 25%. We suspect that it is important to perform a follow-up angiography after angioplasty of supra-aortic arteries, and our result suggests that the restenosis might occur before three months after PTA as well as after coronary angioplasty.
经皮腔内血管成形术（PTA）应用于主动脉弓上动脉。虽然冠状动脉成形术后的首次随访血管造影通常在三四个月后进行，但关于主动脉弓上动脉PTA术后随访血管造影的报道很少。因此，我们对7例患者的8处狭窄进行了成功的PTA术后3个月的随访血管造影。虽然没有发生因再狭窄引起的症状，但在内颈动脉狭窄的4例病例中，有1例显示发生了再狭窄。这是一例左颈总动脉开口处狭窄的病例。锁骨下动脉狭窄的2例病例和左大脑中动脉狭窄的1例病例均未发生再狭窄。总体再狭窄率为25%。我们怀疑在主动脉弓上动脉血管成形术后进行随访血管造影很重要，我们的结果表明，再狭窄可能在PTA术后3个月之前以及冠状动脉成形术后发生。
