大脑后动脉远侧段血管病变的栓塞治疗

Endovascular Treatment of Vascular Diseases in Distal Part of Posterior Cerebral Artery

目的评估血管内栓塞治疗大脑后动脉(PCA)远侧段血管病变的效果。方法回顾性分析近年来经血管内治疗的12例PCA远侧段血管病变(其中动脉瘤4个,血管畸形9个)患者的临床资料。结果2个动脉瘤采用GDC栓塞载瘤动脉,2个动脉瘤采用50%NBCA栓塞,均无偏盲等症状出现;6个AVM栓塞后造影不显影;2个P4-AVM80%栓塞;另1个P4-AVM95%栓塞;仅1例出现1/4象限盲,1例原有偏盲加重。临床随访平均15个月,无再出血和再通。结论血管内栓塞治疗PCA远侧段血管病变是安全可行的。

Objective To evaluate the curative effect of endovascular embolization on vascular diseases in the distal part of posterior cerebral artery(PCA).Methods The clinical data of the3patients with aneurysms,8with AVMs and1with aneurysm and AVM in the distal part of PCA,who received endovascular embolization,were analyzed retrospectively.Results Of4aneurysms,2were treated by embolization of the parent antery with GDC and2were embolized by50%NBCA.Of9AVMs,6were embolized by100%,1by90%and2by80%.Homonymous quadrantanopia occurred in1patient with AVM.The homonymous hemianopia was worse after the treatment than that before the treatment in1patients with AVM.None of the patient suffered from rehemorrhage and recanalization of embolized lesions during following up for15months.Conclusion The endovascular treatment is a safe and effective method for the patients with vascular diseases in the distal part of PCA.
