One case of an aneurysm in the P3 segment and two cases of aneurysms in the P4 segment of the posterior cerebral artery are described. The P3 aneurysm in a 60-year-old female and a P4 aneurysm in a 63-year-old male were clipped or coated via the occipital interhemispheric approach. The other P4 aneurysm in a 73-year-old female was clipped via a hematoma cavity. The occipital interhemispheric approach should be selected for small or large P3 aneurysms and for P4 aneurysms associated with slack brain, as brain retraction is minimal and the approach to the aneurysm is straightforward.
本文描述了1例大脑后动脉P3段动脉瘤和2例P4段动脉瘤。1例60岁女性的P3段动脉瘤和1例63岁男性的P4段动脉瘤通过枕部纵裂入路进行夹闭或包裹。另1例73岁女性的P4段动脉瘤通过血肿腔进行夹闭。对于小型或大型P3段动脉瘤以及与脑松弛相关的P4段动脉瘤，应选择枕部纵裂入路，因为脑牵拉最小且动脉瘤显露直接。
