Object Anterior choroidal artery (AChA) aneurysms are difficult to treat, and the clinical outcome of patients is occasionally compromised by ischemic complications after clipping operations. The purpose of this study was to document the outcome and follow-up results of endovascular coil embolization in patients with AChA aneurysms. Methods Between July 1999 and March 2008, 88 patients with 90 AChA aneurysms (31 ruptured and 59 unruptured aneurysms) were treated with endovascular coil embolization in 91 sessions. There were 87 small aneurysms (< 10 mm) and 3 large aneurysms, with a mean aneurysm volume of 60.9 ± 83.3 mm3. Preprocedural oculomotor nerve palsy associated with AChA aneurysms was noted in 8 patients. Efficacy and safety were evaluated based on the degree of initial occlusion, procedure-related complications, patient outcome based on the Glasgow Outcome Scale score, and follow-up results. Results The degree of angiographic occlusion of the aneurysms was complete for 15 aneurysms (17%), near complete for 69 aneurysms (77%) and partial for 6 aneurysms (7%). There were 4 (4.4%) symptomatic procedure-related complications (3 thromboembolic events and 1 procedural hemorrhage). The procedural hemorrhage resulted in death; however, the thromboembolic events only caused transient deficits. A favorable outcome (Glasgow Outcome Scale score of 5 or 4) was achieved in 90% (79 of 88) of the patients at the time of discharge. No patient showed signs of bleeding or rebleeding during the follow-up period (mean 25 months). Major aneurysm recanalization occurred in 2 cases. The AChA aneurysm–associated oculomotor nerve palsy tended to become aggravated transiently after coil embolization and then completely recovered over the course of 2–9 months. Conclusions Coil embolization is a safe and effective treatment modality in cases of AChA aneurysms. Coil embolization enables procedural recognition of arterial compromise and immediate reestablishment of flow, thus contributing to a favorable outcome.

A 65-year-old male received coil embolization for a large internal carotid-posterior communicating artery aneurysm. Pre- and postoperative angiography at surgery demonstrated that the ipsilateral anterior choroidal artery branched from the internal carotid artery near the distal side of the aneurysm, and elevated and expanded on the aneurysmal dome, but was clearly visualized. Three days following endovascular treatment, the patient presented hemiparesis on the left side, with brain infarction in the territory of the right anterior choroidal artery despite antithrombotic therapy. The delayed brain infarction was likely caused by a reduction in anterior choroidal artery perfusion caused by mechanical compression following a postoperative increase in internal carotid-posterior communicating artery aneurysmal volume during intra-aneurysmal thrombosis. Transient volume expansion after coil embolization for intracranial aneurysms is rarely reported as a cause of brain infarction. It is important to recognize these arteries as potential postoperative complication risks, and consider the use of open surgery to avoid this risk.

We describe a case of arteriovenous fistula (AVF) successfully treated by coil embolization with an anchor coil inserted in the varix to facilitate dense packing at the shunting site. AVF of the left anterior choroidal artery (AChoA) draining into the ipsilateral basal vein of Rosenthal was incidentally found in a newborn female. A single detachable coil was inserted as an anchor into the varix adjacent to the shunt, and the microcatheter was pulled back to the shunting point. Three more detachable coils were delivered at the shunting point without migration under the support of the anchor coil, and the AVF was successfully obliterated with preservation of AChoA blood flow. The anchor coil technique can reduce the risk of coil migration and the number of coils required.

Background Treatment of true ophthalmic artery (OA) or anterior choroidal artery (AChA) aneurysms with preservation of the parent vessel may be challenging. Flow diverters have limitations when dealing with branch vessels arising from the aneurysm sac. Visual loss or AChA territory infarcts have been reported both for surgical and endovascular treatment. Methods We evaluated the safety and efficacy of an open-cell design, laser-cut, self-expanding Nitinol stent, and use of cone-beam computed tomography (CBCT) for stent-assisted coil embolization. Results A total of seven patients with unruptured OA or AChA aneurysms were enrolled in this prospective small case study and the data were analyzed retrospectively. A complete obliteration was achieved in all aneurysms immediately post-intervention or at six-month follow-up without any evidence for recanalization at up to three-year follow-up. All patients tolerated the procedure well and there was no change in baseline modified Rankin Scale. Conclusions Our study suggests that specific features of an open-cell stent allow a safe and effective treatment of OA or AChA aneurysms with a high technical success rate and excellent mid-term angiographic and clinical outcome. CBCT is a useful intraoperative imaging tool.
