A 56-year-old man with ruptured right P2-P3 junction aneurysm and a 66-year-old man with ruptured left P2-P3 junction aneurysm of the posterior cerebral artery associated with acute-stage packed intraventricular hemorrhage. The aneurysms were successfully clipped through the transcortical transchoroidal fissure approach. This approach requires less retraction of the temporal lobe, provides a wider surgical field, and the P2 segment can be easily reached. The present approach is very useful for the treatment of ruptured aneurysms at the P2-P3 junction, in particular for acute stage surgery associated with packed intraventricular hemorrhage.
一名56岁男性患有右侧大脑后动脉P2-P3交界处动脉瘤破裂，一名66岁男性患有左侧大脑后动脉P2-P3交界处动脉瘤破裂，并伴有急性期脑室内积血。通过经皮质经脉络膜裂入路成功夹闭了动脉瘤。该入路需要较少的颞叶牵拉，提供更广阔的手术视野，并且可以轻松到达P2段。本入路对于治疗P2-P3交界处的破裂动脉瘤非常有用，特别是对于伴有脑室内积血的急性期手术。
