Management of a ruptured intraventricular aneurysm arising from distal anterior choroidal artery (AChA): pediatric case report

3D slicer combined with neuroendoscope in treatment of a distal segment aneurysm of the anterior choroidal artery complicated intraventricular hemorrhage: A case report and literature review

“…Because the choroidal artery is a peripheral artery, lacks collateral circulation, and supplies key brain structures such as the basal ganglia and optic tract, surgical treatment of distal choroidal artery aneurysms is extremely challenging and dangerous. At present, there are three surgical methods for such aneurysms, including routine microsurgery, intravascular interventional therapy and neuroendoscopic surgery [ 3 ]. Although conventional microsurgery is technically mature, it has disadvantages such as large trauma and serious complications, which is not the best choice for aneurysms at the distal segment of the artery that are not easy to locate accurately.…”

“…They are usually located at the origin of the anterior choroidal artery, while aneurysms located at the distal segment of the anterior choroidal artery are extremely rare. At present, there are about 31 cases reported in the literature [ 3 ], and fewer aneurysms occur in the posterior choroidal artery, with only 11 cases reported in the literature [ 4 ]. In the past, conservative treatment was often used for such aneurysms, of which about 60% had a poor prognosis due to clinical progressive deterioration or rebleeding.…”

“…With the development of micro-neurosurgery, surgical intervention for these kinds of aneurysms had been gradually attempted. The surgical methods include craniotomy microscope surgery, intravascular interventional therapy and neuroendoscopic surgery [ 3 , 5 ]. Our team recently completed the treatment about a case of pure intraventricular hemorrhage secondary to rupture of a distal segment aneurysm of the anterior choroidal artery using 3D slicer reconstruction and localization system combined with neuroendoscopy.…”

Intraplexal aneurysm of the distal segment of the anterior choroidal artery: A case report and review of literature.

“…146 cases of AchA aneurysms to describe a systematic approach to reduce ischemic complications; none of these cases included post-plexal distal AchA aneurysms, highlighting their rarity (3). We also conducted a literature search using PubMed and found 4 more cases since 2019 (4,5,6). Due to their relatively small size and deep location, the management of distal AChA aneurysms is challenging.…”
