Distal anterior choroidal artery (AChA) aneurysms are infrequent. We discuss the case of a 59-year-old patient who presented with an isolated intraventricular hemorrhage (IVH) secondary to a ruptured distal AChA aneurysm. Initial noninvasive cerebral computed tomography angiography revealed no evidence of an underlying vascular pathology. The patient underwent further digital subtraction cerebral angiography, which revealed an aneurysm arising from the distal AChA segment. The aneurysm was successfully treated with surgical clip ligation. The current study highlights the importance of considering a ruptured distal AChA aneurysm as a potential source of isolated IVH.
脉络膜前动脉(AChA)远端动脉瘤较为少见。我们讨论一例59岁患者,其因脉络膜前动脉远端动脉瘤破裂导致孤立性脑室内出血(IVH)。最初的无创性脑计算机断层扫描血管造影未发现潜在血管病变的证据。患者进一步接受数字减影脑血管造影,结果显示动脉瘤起源于脉络膜前动脉远端节段。该动脉瘤通过手术夹闭成功治疗。本研究强调了将脉络膜前动脉远端动脉瘤破裂视为孤立性脑室内出血潜在病因的重要性。
