“…Causes of the AChA syndrome after surgery mainly include excessive turbulence of blood vessels during surgery, thromboembolism of the AChA and its branches, edema, clip displacement, vasospasm, and reduction of the collateral blood supply. 12,[15][16][17][18] In recent years, many authors have used a variety of methods for detection of accidental AChA obliteration by the clip: intraoperative angiography, muscle motor evoked potentials monitoring 19 ; and intraoperative micro Doppler sonography.…”

Purpose To explore factors affecting the prognosis of choroidal anterior artery aneurysm (AChAA) and provide a reference for improving the postoperative outcome. Methods The clinical data of 86 patients with AChAA who underwent treatment by a single surgeon were collected and analyzed retrospectively. Univariate analysis and multivariate logistic regression analysis were conducted to examine 12 factors that possibly affected outcome. Results The five factors that affected the patient outcomes were times of subarachnoid hemorrhage (SAH), characteristics of SAH on computed tomography (CT), Hunt-Hess grade, aneurysm size, and presence or absence of postoperative complications. Characteristics of SAH on CT (odds ratio [OR]: 3.727; p = 0.000; 95% confidence interval [CI], 1.850–7.508), aneurysm size (OR: 6.335; p = 0.000; 95% CI, 2.564–15.647), and presence or absence of postoperative complications (OR: 4.141; p = 0.000; 95% CI, 1.995–8.599) were independent risk factors influencing the prognosis. In addition, the incidence of postoperative ischemia (caused by anterior choroidal artery syndrome) is related to the aneurysm emitting part and presence or absence of intraoperative rupture. Conclusions The analysis of characteristics of SAH on CT, aneurysm size, and presence or absence of postoperative complications can roughly determine the outcome of patients with AChAAs.

“…Of all diseases that involve the AChA, aneurysms are the most common lesions that can originate from the ICA near the origin of the AChA or arise from the distal AChA 14 . Aneurysms at the junction of the AChA and ICA account for 2%-4% of all intracranial aneurysms; however, distal AChA aneurysms are rare as fewer than 40 cases have been reported to date 15 , 16 . Most distal AChA aneurysms are located in the choroidal segment beyond the plexal point and are associated with MMD, whereas AChA aneurysms in the cisternal segment are extremely rare 17 , 18 .…”

“…Among the appropriate treatments for AChA aneurysms, surgical clipping and resection or endovascular embolization remain the most ideal approaches 15 , 24 . The treatments for aneurysms at the junction of the AChA and ICA are similar to those for other supraclinoid ICA aneurysms.…”

The anterior choroidal artery (AChA) is a critical artery in brain physiology and function. The AChA is involved in many diseases, including aneurysm, brain infarct, Moyamoya disease (MMD), brain tumor, arteriovenous malformation (AVM), etc. The AChA is vulnerable to damage during the treatment of these diseases and is thus a very important vessel. However, a comprehensive systematic review of the importance of the AChA is currently lacking. In this study, we used the PUBMED database to perform a literature review of the AChA to increase our understanding of its role in neurophysiology. Although the AChA is a small thin artery, it supplies an extremely important region of the brain. The AChA consists of cisternal and plexal segments, and the point of entry into the choroidal plexus is known as the plexal point. During treatment for aneurysms, tumors, AVM or AVF, the AChA cisternal segments should be preserved as a pathway to prevent the infarction of the AChA target region in the brain. In MMD, a dilated AChA provides collateral flow for posterior circulation. In brain infarcts, rapid treatment is necessary to prevent brain damage. In Parkinson disease (PD), the role of the AChA is unclear. In trauma, the AChA can tear and result in intracranial hematoma. In addition, both chronic and non-chronic branch vessel occlusions in the AChA are clinically silent and should not deter aneurysm treatment with flow diversion. Based on the data available, the AChA is a highly essential vessel.

“…Some of the particular concerns while considering treatment of these aneurysms are related to the proximity of the AChA and the eloquence of the territory supplied by the AChA 3. Occlusion of the AChA and infarction of its territory classically results in contralateral hemiparesis, hemianesthesia, and homonymous hemianopsia 4.…”

“…In addition, it is often necessary to leave a neck remnant during coil embolization to preserve the patency of the AChA, given their frequent shared origin. Thus, FD offers an attractive alternative: it has worked well for other aneurysms of the carotid siphon, avoids direct aneurysmal catheterization, and may offer better occlusion rates for these aneurysms that are challenging for coiling 3. To date, the results of FD on AChA aneurysms has not been reported in detail as a separate entity.…”
