Transcatheter arterial embolization using a coaxial microcatheter and micro-coil was performed in eight patients with vascular lesions; one each with aneurysm of the basilar artery, cerebellar artery, and pancreatic artery, pseudoaneurysm of the common hepatic artery, gastroduodenal artery, and gluteal artery, carotid-cavernous fistula, and thoracic paraspinal arteriovenous malformation. Complete occlusion was achieved in five patients with aneurysm and pseudoaneurysm by occluding the aneurysmal cavity and/or the orifice. A patient with recurrent carotid-cavernous fistula was also completely embolized. A case of basilar artery aneurysm resulted in partial occlusion because the posterior cerebral artery originated from the aneurysm. The unsatisfactory result in a case of paraspinal AVM was due to its wide extension with multiple feeding arteries. No apparent complication was seen. In conclusion, super-selective arterial embolization therapy with coaxial microcatheter and micro-coils was found to be a useful method for vascular lesions that would have been technically difficult to embolize with the standard catheter and coils.
对8例血管病变患者采用同轴微导管和微弹簧圈进行经导管动脉栓塞术；其中1例为基底动脉、小脑动脉和胰动脉动脉瘤，1例为肝总动脉、胃十二指肠动脉和臀动脉假性动脉瘤，1例为颈内动脉海绵窦瘘，1例为胸段椎旁动静脉畸形。5例动脉瘤和假性动脉瘤患者通过闭塞瘤腔和/或瘤口实现了完全闭塞。1例复发性颈内动脉海绵窦瘘患者也完全栓塞。1例基底动脉动脉瘤因大脑后动脉起源于动脉瘤而导致部分闭塞。1例椎旁动静脉畸形治疗效果不佳是由于其广泛延伸且有多个供血动脉。未观察到明显并发症。总之，对于使用标准导管和弹簧圈在技术上难以栓塞的血管病变，同轴微导管和微弹簧圈超选择性动脉栓塞治疗是一种有用的方法。
