经皮穿刺球囊血管成形术日益广泛地应用于治疗先天性或手术后的瓣膜或血管狭窄。本文报道了此术并发脑血管意外。病例 1,男,3岁5月,体重15kg。临床和超声心动图发现主动脉瓣两叶畸形伴主动脉瓣狭窄,左室壁显著增厚、收缩力增强。体格发育和神经系统检查均正常。心导管检查左室与主动脉压差为14.7kPa,经球囊扩张5次,因不 Percutaneous balloon angioplasty is increasingly used to treat congenital or postoperative valves or vascular stenosis. This article reports the complications of cerebrovascular accident. Case 1, male, 3 years old in May, weighing 15kg. Clinical and echocardiographic findings of aortic valve two lobe malformations with aortic stenosis, left ventricular wall was significantly thickening, contractility increased. Physical development and neurological examination were normal. Cardiac catheterization left ventricular and aortic pressure was 14.7kPa, the balloon dilation 5 times, because of no
