Intra-operative transluminal angioplasty of supra-aortic vessels was performed in 9 patients. All subjects had lesions which were considered difficult or impossible to operate upon. In 2 patients a proximal occlusion of the left subclavian artery was dilated. Seven subjects showed severe stenoses of the supra-aortic vessels: common carotid artery: 1, internal carotid artery: 2, external carotid artery: 1, external carotid artery prosthetic graft: 1, brachiocephalic trunk: 1, vertebral artery: 1. All patients suffered from symptoms which corresponded to the site of the lesions in question. Intra-operative angioplasty was primarily successful in all 9 patients. Re-occlusion occurred within a few days in both patients who underwent angioplasty of the subclavian artery. Six of the seven subjects with stenotic lesions remained free of symptoms and of restenosis. In the case of dilatation of a prosthetic graft of the external carotid artery asymptomatic occlusion developed within 8 weeks. In selected cases intra-operative angioplasty is a potentially valuable alternative in the treatment of surgically inaccessible lesions of the supra-aortic vessels.
9例患者接受了术中经腔主动脉弓血管成形术。所有患者的病变均被认为难以或无法进行手术治疗。2例患者扩张了左锁骨下动脉近端闭塞病变。7例患者表现为主动脉弓血管严重狭窄：颈总动脉1例，颈内动脉2例，颈外动脉1例，颈外动脉人工血管1例，头臂干1例，椎动脉1例。所有患者的症状均与相关病变部位相符。术中血管成形术在所有9例患者中初步成功。接受锁骨下动脉血管成形术的2例患者在数天内发生再闭塞。7例狭窄病变患者中有6例无症状且无再狭窄。在颈外动脉人工血管扩张的病例中，8周内出现无症状闭塞。在某些特定病例中，术中血管成形术是治疗主动脉弓血管手术难以触及病变的一种潜在有价值的替代方法。
