World Neurosurg 2024; 187:e1072-e1082. [PMID: 38750889 DOI: 10.1016/j.wneu.2024.05.050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 05/08/2024] [Accepted: 05/09/2024] [Indexed: 07/07/2024]
Abstract
OBJECTIVE This study describes our experiences with anterior choroidal artery (AChA) aneurysm clipping with a focus on visualizing the AChA just behind the aneurysm to identify the risk factors for adhesion of the AChA or its branches to the posterior wall of the AChA aneurysm. METHODS The initial segment of the AChA just behind the aneurysm was evaluated preoperatively using three-dimensional (3D) rotational angiography, and its course was designated as posteromedial, posterior, or posterolateral. The posterior aspect of the AChA aneurysm was inspected intraoperatively using an endoscope or micromirror. RESULTS Based on 3D rotational angiography, the main trunk of the AChA showed a posteromedial (n = 47, 57.3%), posterior (n = 18, 22.0%), or posterolateral (n = 17, 20.7%) course just behind the aneurysm. Intraoperatively, 14.6% (12 of 82) of the clipped AChA aneurysms revealed an AChA branch adhered to the posterior wall of the aneurysm. A multivariate analysis revealed that the posterior or posterolateral course of the initial segment of the AChA was a statistically significant risk factor for adhesion of an AChA branch to the posterior wall of the aneurysm (odds ratio [OR] 21.083, 95% confidence interval [CI] 2.567-173.166, P = 0.005). CONCLUSIONS The initial course of the AChA just behind an AChA aneurysm can be evaluated using 3D rotational angiography. In contrast to a posteromedial course, a posterior or posterolateral course of the AChA just behind an AChA aneurysm can be a significant risk factor for adhesion of an AChA branch to the posterior wall of an AChA aneurysm.

J Stroke Cerebrovasc Dis 2024; 33:107679. [PMID: 38499080 PMCID: PMC11088492 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107679] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Revised: 03/07/2024] [Accepted: 03/13/2024] [Indexed: 03/20/2024] Open
Abstract
BACKGROUND Anterior choroidal artery (AchoA) aneurysms are relatively rare compared to other types of aneurysms. However, the occurrence of transient or permanent occlusion of the choroidal artery during endovascular or surgical treatment is an uncommon but potentially serious complication. In this study, we aim to investigate the safety and efficacy profile of endovascular treatment (EVT) for AchoA aneurysms. METHODS The primary outcome of interest was angiographic and clinical outcomes. Secondary outcome variables transient and permanent ischemic complications, symptomatic choroidal artery occlusion and retreatment rates. A random-effects model was used to calculate prevalence rates and their corresponding 95 % confidence intervals (CI), and subgroup analyses were performed to assess the complication rates for Type 1(arterial type, directly arising from ICA) and Type 2(neck type, arising from AchoA branch)) AchoA aneurysms, ruptured vs non-ruptured and for flow diverter (FD) treatment versus coiling. RESULTS Our study included 10 studies with 416 patients with 430 AchoA aneurysms. The overall good clinical outcome rate (mRS score 0-2) is 94.5 % with a retreatment rate of 2.0 %. A subgroup analysis showed no statistical difference between coiling(75.3 %) and flow diverter(80.9 %) treatment in terms of complete occlusion(p-value:0.62). Overall permanent complication rate is 1.4 % (p-value:0.54) and transient ischemic complications rate is 4.2 %(p-value:0.61). Symptomatic choroidal artery occlusion rate is 0.8 %(p-value:0.51)Type 2 AchoA aneurysms had a significantly higher complication rate of 9.8 % (p-value<0.05) compared to Type 1 aneurysms. Unruptured aneurysms have significantly better clinical outcomes than ruptured aneurysms(OR: 0.11; [0.02;0.5], p-value:<0.05) CONCLUSION: Endovascular treatment of AchoA aneurysms demonstrated positive clinical results, with low rates of retreatment and complications. Coiling and flow diverters proved similar outcomes in achieving aneurysm occlusion. Ruptured aneurysms have lower good clinical outcomes comparing to unruptured aneurysms. Type 2 AchoA aneurysms had a higher risk of complications compared to Type 1.

Int J Neurosci 2024:1-8. [PMID: 38189419 DOI: 10.1080/00207454.2024.2303369] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Accepted: 01/04/2024] [Indexed: 01/09/2024]
Abstract
OBJECTIVE To compare the therapeutic efficacy of endovascular interventional embolization and microsurgical clipping in patients with ruptured cerebral aneurysms and investigate their subsequent influence on inflammatory indices, neurological function, prognosis, and recovery. METHODS The two groups were compared in terms of surgery duration, hospital stay, Hunt-Hess classification, and inflammatory indices before and after the surgery, as well as National Institutes of Health Stroke Scale (NIHSS), Baethel Index (BI), and one-year prognosis of patients affected. RESULTS The surgery duration and hospital stay of the intervention group were (116.27 ± 12.32) min and (19.82 ± 2.26) d, respectively, and those of the clipping group was (173.87 ± 10.39) min and (24.11 ± 2.33) d, respectively (both p < 0.05). Neither the intervention nor the microscopic approach had a significant impact on the severity of the patients' conditions in terms of Hunt-Hess classification (p > 0.05). In the intervention group, CRP was changed to (5.31 ± 1.22) mg/L and PCT decreased to (1.17 ± 0.39) μg/L after the surgery, while the corresponding values in clipping group were (9.78 ± 2.35) mg/L and (2.75 ± 0.81) μg/L (p > 0.05). After surgery, both groups' NIHSS scores declined dramatically, with the intervention group scoring lower than the microscopy group (6.81 ± 1.22 vs 8.72 ± 1.27) (p < 0.05). CONCLUSION The findings of this study support the potential advantages of endovascular interventional embolization (coiling) over microsurgical clipping for the management of ruptured cerebral aneurysms. These advantages include shorter surgical duration, reduced hospital stay, lower inflammatory response, improved neurological and functional outcomes, and better long-term prognosis.

Abstract
PURPOSE Temporary arterial occlusion (TAO) is a widespread practice in the surgical treatment of intracranial aneurysms. This study aimed to investigate TAO's role during ruptured aneurysm clipping as an independent prognostic factor on short- and long-term outcomes. METHODS This prospective cohort included 180 patients with ruptured intracranial aneurysms and an indication of microsurgical treatment. Patients who died in the first 12 hours after admission were excluded. RESULTS TAO was associated with intraoperative rupture (IOR) (odds ratio - OR = 10.54; 95% confidence interval - 95%CI 4.72-23.55; p < 0.001) and surgical complications (OR = 2.14; 95%CI 1.11-4.07; p = 0.01). The group with TAO and IOR had no significant difference in clinical (p = 0.06) and surgical (p = 0.94) complications compared to the group that had TAO, but no IOR. Among the 111 patients followed six months after treatment, IOR, number of occlusions, and total time of occlusion were not associated with Glasgow Outcome Scale (GOS) in the follow-up (respectively, p = 0.18, p = 0.30, and p = 0.73). Among patients who underwent TAO, IOR was also not associated with GOS in the follow-up (p = 0.29). CONCLUSIONS TAO was associated with IOR and surgical complications, being the latter independent of IOR occurrence. In long-term analysis, neither TAO nor IOR were associated with poor clinical outcomes.

Abstract
SAH (subarachnoid hemorrhage) caused by aneurysm rupture has the greatest mortality rate, with nearly 50% of patients unable to survive beyond 1 month after the attack. Anterior choroidal artery (AChA) aneurysms are one of the most difficult to treat among the numerous types of aneurysms. Until now, some neurosurgeons employed shearing while others employed coiling. In this trial, researchers will compare surgical clipping and endovascular coiling treatments for anterior choroidal artery aneurysms in terms of mortality, rebleeding, retreatment, and post-procedure outcomes. Using the PubMed electronic database, the Cochrane library, the Medline Database, the Directory of Open Access Journals, and EBSCHOHOST, a systematic review compared surgical clipping and endovascular coiling in all cases of choroidal artery aneurysm. There were 17 studies that met the eligibility requirements, with a total of 1486 patients divided into groups that underwent clipping (1106) or endovascular coiling (380). The mortality rate for clipping is 1.8%, while the mortality rate for endovascular coiling is 2.34%. Rebleeding occurs in 0% of patients undergoing endovascular coiling and 0.73% of patients undergoing clipping. Retreatment of clipping was 0.27%, while endovascular coiling was 3.42%. Post-complication procedures occurred in 11.12% of patients undergoing endovascular clipping and 15.78% of patients undergoing endovascular coiling. The intervention technique of clipping has a reduced rate of mortality, reoperation, and post-operative complications. Endovascular coiling results in a reduced rate of rebleeding than clipping.

Abstract
BACKGROUND This study aimed to identify the association between the number of anterior choroidal arteries (AchoAs) and procedure-related ischemic complications in microsurgical clipping of unruptured AchoA aneurysms. METHODS We retrospectively reviewed the clinical, radiological, and intraoperative findings of 153 patients with unruptured AchoA aneurysms treated with microsurgical clipping between January 2012 and November 2020 in a single tertiary institution. Intraoperative video clips were reviewed, and the AchoA type was categorized into two according to the number of AchoAs: (1) single-type group with single origin and single branch and (2) multiple-type group with duplicated origin or divided multiple branches. Uni- and multivariate analyses were performed to assess the relationship between clinical and radiological factors and perioperative ischemic complications. RESULTS Of the 153 patients, 52 (34%) were categorized as multiple-type group. The frequency of perioperative ischemic complications, including decreased intraoperative motor evoked potential (MEP), silent infarction, and postoperative ischemic symptoms, was significantly higher in the multiple-type group than in the single-type group (13 [25%] vs 6 [5.9%], p = 0.001). Multivariate logistic regression analysis showed that multiple-type group (odds ratio [OR], 3.725; 95% confidence interval [CI], 1.171-11.845, p = 0.026) and multilobulated shape (OR, 9.512; 95% CI, 2.093-43.224; p = 0.004) were significantly associated with perioperative ischemic complications. Among 9 patients with decreased MEP, postoperative ischemic symptoms developed in 2 patients after clip adjustment. CONCLUSIONS Multiple-type AchoA aneurysms and multilobulated shape are significantly correlated with perioperative ischemic complications. Postoperative ischemic complications can be minimized by recognizing these variations and using multimodal approach with MEP monitoring.

Abstract
During intraoperative monitoring of motor evoked potentials (MEP), heterogeneity across studies in terms of study populations, intraoperative settings, applied warning criteria, and outcome reporting exists. A scoping review of MEP warning criteria in supratentorial surgery was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Sixty-eight studies fulfilled the eligibility criteria. The most commonly used alarm criteria were MEP signal loss, which was always a major warning sign, followed by amplitude reduction and threshold elevation. Irreversible MEP alterations were associated with a higher number of transient and persisting motor deficits compared with the reversible changes. In almost all studies, specificity and Negative Predictive Value (NPV) were high, while in most of them, sensitivity and Positive Predictive Value (PPV) were rather low or modest. Thus, the absence of an irreversible alteration may reassure the neurosurgeon that the patient will not suffer a motor deficit in the short-term and long-term follow-up. Further, MEPs perform well as surrogate markers, and reversible MEP deteriorations after successful intervention indicate motor function preservation postoperatively. However, in future studies, a consensus regarding the definitions of MEP alteration, critical duration of alterations, and outcome reporting should be determined.
