A hyperplastic anterior choroidal artery with double persistent anastomotic channels.

چکیده
We describe a case of a hyperplastic anterior choroidal artery (AChA) with double persistent anastomotic channels. This hyperplastic AChA, which was detected at vertebral angiography, is different from previously reported cases, because it has an unusual, secondary anastomotic channel.

In the first part of this investigation, 216 consecutive carotid angiograms from 108 patients were reviewed to analyze variations of the anterior choroidal artery (AChA) for the origin, size, and course of the stem and for the possible identification of the uncal branch, perforating branches, and plexal segment of the AChA. In the second part of our investigation, we analyzed anomalies of the A...

A 65-year-old man presented with a hyperplastic anomalous anterior choroidal artery (AChA) associated with a ruptured internal carotid artery aneurysm at the origin of a perforating artery manifesting as sudden onset of headache and vomiting. The aneurysm was too small for endovascular embolization, so we performed open surgery via the left pterional approach. Aneurysm clipping with preservatio...

An 18-year-old man presented with a rare case of a ruptured internal carotid artery (ICA)-persistent primitive anterior choroidal artery (PPAchA) manifesting as sudden onset of headache. Computed tomography (CT) showed subarachnoid hemorrhage. Three-dimensional CT angiography showed a saccular aneurysm at the right ICA-AchA region. Right internal carotid angiography showed a PPAchA and saccular...
متن کاملAnterior choroidal artery patency and clinical follow-up after coverage with the pipeline embolization device.
BACKGROUND AND PURPOSE Endoluminal reconstruction with the Pipeline Embolization Device is an effective treatment option for select intracranial aneurysms. However, concerns for the patency of eloquent branch arteries covered by the Pipeline Embolization Device have been raised. We aimed to examine the patency of the anterior choroidal artery and clinical sequelae after ICA aneurysm treatment. ...
