Endovascular treatment strategies and a new classification for multiple aneurysms of the ipsilateral ophthalmic segment of the internal carotid artery. Asian J Surg 2023; 46:3663-3672. [PMID: 37012159 DOI: 10.1016/j.asjsur.2023.03.134] [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: 11/02/2022] [Accepted: 03/23/2023] [Indexed: 04/03/2023] Open
Abstract
OBJECTIVE Aneurysms occurring in the ophthalmic segment (C6) of the internal carotid artery (ICA) have complex anatomy. This poses a challenge for the use of traditional open surgery, which is gradually being replaced by endovascular treatment (EVT). However, multiple aneurysm (MA) EVT, especially in MAs occurring ipsilaterally, has not been specifically described or discussed. The present study aimed to propose a more concise clinical classification standard for ipsilateral C6 ICA MAs and report on the clinical experience with EVT. METHODS The cases of 18 patients with ipsilateral C6 ICA MAs treated with EVT were retrospectively reviewed. The treatment results and procedure-related complications were recorded, and clinical and angiographic follow-ups were performed at least six months after surgery. RESULTS A total of 38 ipsilateral C6 ICA aneurysms were treated during the study period and classified into four main types and six total subtypes based on anatomical features. There was a failure to coil through the stent in one aneurysm, while the remaining 37 were successfully treated using various EVT methods. Of these, 36 were completely concluded. One aneurysm had a size reduction, and one had no changes during the angiographic follow-up. All Tubridge flow diverter stents were patent. All patients achieved satisfactory clinical outcomes and were independent at the final follow-up. CONCLUSION EVT may be safe and feasible for the treatment of C6 ICA MAs. Traditional stent-assisted coiling methods, the Willis covered stent, and the double-layered low-profile visualized intraluminal support stent all achieved favorable results. The flow diverter stent is also considered a safe and efficient option for selected aneurysms, but the visual deficit risk should be considered. The present study introduces a new EVT classification option based on the anatomical features of an aneurysm.

Transradial Stent-Assisted Coiling Using "Dual-Jailing" Technique for Kissing Aneurysms of the Internal Carotid Artery: Technical Note and Literature Review. World Neurosurg 2023; 170:175-181. [PMID: 36368455 DOI: 10.1016/j.wneu.2022.11.018] [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: 09/30/2022] [Accepted: 11/06/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND Kissing aneurysms are an unusual type of multiple intracranial aneurysms having different origins with partially adherent walls. Although endovascular treatment is a useful alternative to surgical clipping, endovascular management for small wide-necked kissing aneurysms has not been adequately investigated to date. Herein, we present a case of small wide-necked kissing aneurysms successfully treated with transradial stent-assisted coiling (SAC) using the "dual-jailing" technique. We also performed a review of the relevant literature. CASE PRESENTATION A 64-year-old woman who was diagnosed with small wide-necked kissing aneurysms relating to the ophthalmic artery underwent SAC using the dual-jailing technique. After a 6F Simmons guiding sheath was delivered into the target common carotid artery via transradial access, a 6F intermediate catheter was navigated into the petrous internal carotid artery to achieve both triple microcatheter manipulation and contrast injection. Two coil-delivery microcatheters were cannulated into each aneurysm, followed by a Neuroform Atlas stent deployment over the aneurysm necks via a third stent-delivery microcatheter. By using the jailed microcatheters, SAC of the kissing aneurysms was successfully achieved, preserving the ophthalmic artery. The postprocedural course was uneventful. A follow-up magnetic resonance angiography showed no evidence of recanalization 2 years 3 months post procedure. CONCLUSIONS The dual-jailing technique may provide simple and time-saving SAC compared with previous reported method. This technique can be a useful treatment option for small wide-necked kissing aneurysms.

Abstract
Background Tubridge flow diverter is a widely used device aimed at reconstructing parent arteries and occluding complex aneurysms in China. The experience of Tubridge in treating small and medium aneurysms is still limited. In this study, we aimed to evaluate the safety and efficacy of the Tubridge flow diverter for the treatment of the two types of aneurysms. Methods We reviewed the clinical records of aneurysms treated with a Tubridge flow diverter between 2018 and 2021 in a national cerebrovascular disease center. Cases were divided into small and medium aneurysms according to aneurysm size. The therapeutic process, occlusion rate, and clinical outcome were compared. Results In total, 57 patients and 77 aneurysms were identified. The patients were divided into two groups: small aneurysms (39 patients, 54 aneurysms) and medium aneurysms (18 patients, 23 aneurysms). There were 19 patients with tandem aneurysms (a total of 39 aneurysms) in the two groups, among which 15 patients (30 aneurysms) were in the small aneurysm group and four patients (nine aneurysms) were in the medium aneurysm group. The results show that the mean maximal diameter/neck in the small and medium aneurysms was 3.68/3.25 and 7.61/6.24 mm, respectively. In total, 57 Tubridge flow diverters were successfully implanted without unfolding failure, and there were six patients with new mild cerebral infarction in the small aneurysm group. The complete occlusion rate on the last angiographic follow-up was achieved in 88.46% of the small aneurysms group and 81.82% of the medium aneurysms group. The complete occlusion rate of patients with tandem aneurysms in the last angiographic follow-up was 86.67% (13/15) of the small aneurysms group and 50% (2/4) of the medium aneurysm group. Intracranial hemorrhage was nonencountered in the two groups. Conclusion Our preliminary experience suggests that the Tubridge flow diverter might be a safe and effective treatment for small and medium aneurysms along the internal carotid artery. Long stents may increase the risk of cerebral infarction. Adequate evidence is required to clarify the definite indications and complications in a multicenter randomized controlled trial with a long-term follow-up.

Microsurgical Clipping of Carotid-Ophthalmic Tandem Aneurysms: Case Report and Surgical Nuances. ACTA ACUST UNITED AC 2021; 57:medicina57070731.

Abstract
Tandem intracranial aneurysms (TandIAs) are rare but inherently complex, and special technical considerations are required for their surgical management. The present case highlights the key surgical aspects of two carotid-ophthalmic TandIAs incidentally found in a 60-year-old female. Both the aneurysms were superiorly projecting, regular in size, and involved the left ophthalmic segment of the internal carotid artery (ICA). The minimum distance between the necks was 3 mm. The patient underwent microsurgery because of the reported major complications rate of the endovascular treatment in the case of a very short minimum distance between the TandIAs. After cervical ICA exposure, both the aneurysms were excluded through a pterional approach. Intradural anterior clinoidectomy and unroofing of the optic canal allowed the mobilization of the left optic nerve. The more distal aneurysm was clipped before the opening of the distal dural ring of the ICA. The proximal aneurysm was clipped with two straight clips stacked perpendicular to the ICA. A small remnant was intentionally left to avoid the stenosis of the ophthalmic artery. Postoperative angiography showed the exclusion of both the aneurysms with a small dog-ear of the more proximal one. The patient was discharged neurologically intact and, after one year, the remnant remained stable. Microsurgical clipping is a definitive and durable treatment for carotid-ophthalmic TandIAs. In the case of a very short minimum distance between the aneurysms, the distal one should be clipped first to make the anterior clinoidectomy, opening of the distal dural ring of the ICA, and clipping of the more proximal aneurysm easier.

The Minimum Distance May Affect Perioperative Complications and Completed Occlusions of Endovascular Treatment for Tandem Intracranial Aneurysms: A Multi-Institutional Retrospective Study.

Abstract
BACKGROUND Tandem aneurysms (TAs) are a distinct type of multiple intracranial aneurysms (IAs), the treatment strategies for which remain controversial. We aimed to reveal the clinical and angiographic outcomes of endovascular treatment as well as their risk factors in these complex multiple IAs. METHODS This multicenter, retrospective follow-up study was carried out in 3 hospitals in China. In total, clinical and angiographical data of 137 patients with 145 lesions (7 patients had bilateral lesions) and 315 TAs were collected. The treatment strategies were divided into full or partial treatment, single- or multiple-session treatment, and coiling (including single coiling and stent-assisted coiling)- or flow-diverting stent (FDS) treatment. Perioperative complications, as well as angiographic and clinical outcomes and their risk factors, were analyzed using univariate analysis and a multiple regression model. RESULTS Of treated TA lesions, 17 (16.0%) perioperative complications were found. Significant differences were found between the single- and multiple-session treatment groups (p = 0.012). At the latest follow-up, there were no significant differences in the modified Raymond Scale scores between different treatment groups. Significant differences were found in the embolization degree between the coiling and FDS groups (p = 0.038) and between the single common stent (without coiling) and the other treatment groups (p < 0.001). In IAs managed by a single LVIS stent (without coiling), 60% achieved improved or completed occlusion. Multivariate regression analysis found that a shorter minimum distance (odds ratio [OR] 5.967, 95% confidence interval [CI] 1.366-26.074; p = 0.018), multiple-session treatment (OR 9.961, 95% CI 1.707-58.127; p = 0.011), and diabetes (OR 8.106, 95% CI 1.928-34.084; p = 0.004) were predictors of perioperative complications, while shorter minimum distance (OR 5.619, 95% CI 1.493-21.152; p = 0.011), greater diameter ratio (OR 3.621, 95% CI 1.014-12.937; p = 0.048), and greater size ratio (OR 2.424, 95% CI 1.007-5.834; p = 0.048) were predictors of low completed occlusion rate. CONCLUSIONS Both coiling and FDS can be utilized safely and can achieve similar clinical outcomes. FDS and LVIS are recommended for IAs that do not require embolization but cannot be prevented from being covered by stents. A multiple-session treatment may increase the treatment risk, and the minimum distance may affect the incidence of perioperative complications and completed occlusions. Further hemodynamic and prospective studies on such TAs in close proximity to one another are needed.

Abstract
The treatment of intracranial aneurysms has undergone a few very significant paradigm shifts in its history. Needless to say, microsurgery and surgical clipping served as the initial basis for successful treatment of these lesions. The pursuit of endovascular therapy subsequently arose from the desire to reduce the invasiveness of therapy. While the first breakthrough arose with Guido Guglielmi's invention of the detachable platinum coil, commercialized flow diverter therapy represents a disruptive therapy with a completely different paradigm for aneurysmal obliteration. This has not only altered the distribution of aneurysmal management strategies, but also opened the gateway to the treatment of previously inoperable lesions. With the basic flow diverter stent technology now considered an integral part of the neurointerventional armamentarium, we now consider what may lay in the future - including potential directions for research with regards to case selection; the location and type of aneurysms which may become routinely treatable; and modifications to the flow diverter, which may increase its utility and safety in terms of size, structural design, and surface modifications.

Abstract
BACKGROUND Controversy exists regarding the optimum number of flow diverters for the treatment of intracranial aneurysms. We explored the effect of the number of Pipeline embolization devices (PEDs; Medtronic, Dublin, Ireland) deployed on rates of aneurysm occlusion and complications. METHODS Consecutive patients who underwent saccular intracranial aneurysm treatment solely with the PED were included in this retrospective study. Computed tomographic, magnetic resonance, or digital subtraction angiographic images at 6 and 12 months and last follow-up (>12 months) were reviewed for aneurysm occlusion. Complication and retreatment rates were recorded and analyzed statistically. RESULTS The study included 141 aneurysm treatments in 119 patients. A single PED was deployed in 105 cases, two PEDs in 31 cases, and three PEDs in 5 cases (total = 182 devices). Six-month angiographic data were available for 103 patients. Occlusion rates were 67.1% for single-PED cases and 90.0% for cases with > 1 PED (p = 0.028). The 12-month occlusion rate (follow-up available for 132) for single-PED cases was 74.7% compared to 91.7% for multiple-PED cases (p = 0.04). On multivariate analysis, number of PEDs was an independent predictor of aneurysm occlusion at 12 months (odds ratio 6.3, 95% confidence interval 1.8-22.8, p = 0.005). Thromboembolic complication rates were the same in the single- and multiple-PED treatment groups (2.8%). The retreatment rate was higher in patients treated with a single PED (16.2% vs. 0%, p = 0.01). CONCLUSIONS Deployment of > 1 Pipeline embolization device was associated with higher intracranial aneurysm occlusion and lower retreatment rates. No significant difference was found in complication rates.

Abstract
BACKGROUND To systematically assess the efficacy and safety between flow diversion and coiling for patients with unruptured intracranial aneurysms. METHODS Potential academic articles were identified from Cochrane Library, Medline, PubMed, EMBASE, ScienceDirect, and other databases. The time range we retrieved from was the inception of electronic databases to February 2019. Gray studies were identified from the references of included literature reports. STATA version 11.0 was used to analyze the pooled data. RESULTS A total of 11 articles (10 retrospective studies and 1 prospective study) were involved in our study. The overall participants of the coiling group were 611, whereas 576 were in the flow diversion group. Our meta-analysis showed that flow diversion was preferable for unruptured intracranial aneurysms as its lower value of total cost per case (weighted mean difference, 5705.906; 95% confidence interval [CI], [4938.536, 6473236]; P < 0.001), fluoroscopy time per case (weighted mean difference, 25.786; 95% CI, 17.169-34.377; P < 0.001), and retreatment rates (odds ratio [OR], 7.127; 95% CI, [3.525, 14.410]; P < 0.001), at the same time, a higher rate of immediate completed occlusion (OR, 0.390; 95% CI, [0.224, 0.680]; P = 0.001) and follow-up completed occlusion (OR, 0.173; 95% CI, [0.080, 0.375]; P < 0.001) was demonstrated in the flow diversion group. There was no difference on intraoperative complication rates (P = 0.070), procedure-related mortality (P = 0.609) and rupture rates (P = 0.408), modified Rankin Scale (mRS) 0-2 at discharge (P = 0.077), and mRS 0-2 at follow-up (P = 0.484). CONCLUSIONS The use of flow diversion for the treatment of unruptured intracranial aneurysms may reduce total cost per case, fluoroscopy time per case, retreatment rates, and increases immediate completed occlusion and follow-up completed occlusion rates without affecting the results of mRS and intraoperative complication.

[PMID: 30167711 DOI: 10.1007/s00062-018-0723-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2018] [Accepted: 08/12/2018] [Indexed: 11/26/2022]
Abstract
BACKGROUND AND PURPOSE Intracranial adjacent tandem lesions of the internal carotid artery (ICA) are rare and the optimal treatment strategy is unknown. This study was carried out to determine whether a single flow diverter stent (FDS) could be successfully used to treat these lesions. METHODS The prospectively maintained database was retrospectively carried out to identify patients treated between February 2009 and February 2018 with multiple unruptured, tandem ICA aneurysms and treated with a single FDS. Demographic data, clinical presentation, aneurysm characteristics, treatment data, clinical result and clinical and radiological follow-up information were recorded. RESULTS A total of 69 patients (62 female, 89.8%) with average age 55 ± 14.8 years were identified. In total there were 169 aneurysms and the majority of patients (n = 47, 68.1%) had only 2 tandem aneurysms. The largest aneurysms measured 7.69 ± 5.3 mm (range 1.5-26 mm) in height, 6.64 ± 4.71 mm (range 1.5-23 mm) in width and the smaller aneurysm measured 2.61 ± 1.32 mm (range 0.8-9.5 mm) in height and 2.32 ± 1.12 mm (range 0.7-8 mm) in width. In 36 patients the p64 was used, the PED in 28 patients and Surpass in 5 patients. Follow-up was available in 54 patients (130 aneurysms). At initial follow-up (7.2 ± 4.2 months) 45 (83.3%) of the larger aneurysms and 66 (86.8%) of the smaller aneurysms were satisfactorily occluded (Raymond-Roy classification RRC 1 or 2). At delayed follow-up (18 ± 14.6 months) 48 of the larger aneurysms (88.9%) and 71 of the smaller aneurysms (93.4%) were satisfactorily occluded. There were three complications including one death. CONCLUSION A single FDS can be used to successfully treat multiple tandem aneurysms of the ICA with a high rate of aneurysm exclusion and an acceptable risk profile.

Treatment of Small and Tiny Aneurysms Before and After Flow Diversion Era: A Single Center Experience of 409 Aneurysms. World Neurosurg 2018; 116:e386-e393.

Abstract
OBJECTIVE To explore whether we should use the Pipeline embolization device (PED) as the primary treatment modality for small and tiny aneurysms at anterior circulation. METHODS This retrospective study included 409 cases of small and tiny aneurysms, including aneurysms treated by the PED (n = 77), coiling (n = 51), and stent-assisted coiling (SAC) (n = 281). We also made a comparison regarding the safety and efficacy among these treatment modalities. RESULTS A total of 55 patients with 77 small aneurysms were treated with PEDs. Technical success was achieved in 98.4% of procedures. The complete occlusion rate was 75.9% (44/58). Both the morbidity and mortality rates were 1.8%. Comparing the 3 treatment modalities, the technical event rate tended to be the highest in the PED group (4.8% vs. 2.0% and 1.1%; PED vs. Coil vs. SAC; P = 0.100), and the use of a PED neither significantly shortened the procedure duration (127.2 ± 62.8 vs. 115 ± 37.1 and 112.8 ± 40.6 minutes, P = 0.322) nor lowered the complication rate (11.1% vs. 9.8% and 6.1%; P = 0.281). SAC had the highest occlusion rate (75.9% vs. 75.8% and 94.0%; P < 0.001) and lowest morbidity rate (0.8% vs. 4.2% and 1.8%; SAC vs. Coil vs. PED; P = 0.099). Ipsilateral multiple aneurysms were more frequently seen in the PED group (33.8% vs. 3.9% and 3.2%; P < 0.001). Procedure duration tended to be lower in the PED group versus the SAC group (122.7 ± 57.4 vs. 157.5 ± 22.2 minutes; P = 0.060). For these aneurysms, the PED group had the highest occlusion rate (80.0% vs. 50.0% and 66.7%; P = 0.516). CONCLUSIONS The PED is an alternative treatment for small and tiny aneurysms. However, SAC remains the safest and most efficient treatment modality. The PED should be reserved for ipsilateral multiple aneurysms.

Abstract
OBJECTIVE Flow diversion has proven to be an efficacious means of treating cerebral aneurysms that are refractory to other therapeutic means. Patients with tandem aneurysms treated with flow diversion have been included in larger, previously reported series; however, there are no dedicated reports on using this technique during a single session to treat this unique subset of patients. Therefore, the authors analyzed the outcomes of patients who had undergone single-session flow diversion for the treatment of tandem aneurysms. METHODS The authors conducted a retrospective review of flow diversion with the Pipeline embolization device (PED) for the treatment of tandem aneurysms in a single session at 2 participating medical centers: University of Utah, Salt Lake City, Utah, and Barrow Neurological Institute, Phoenix, Arizona. Patient demographic data, aneurysm characteristics, treatment strategy and results, complications, and follow-up data were collected from the medical record and analyzed. RESULTS Between January 2011 and December 2015, 17 patients (12 female, 5 male) with a total of 38 aneurysms (mean size 4.7 ± 2.7 mm, mean ± SD) were treated. Sixteen patients had aneurysms in the anterior circulation, and 1 patient had tandem aneurysms in the posterior circulation. Twelve patients underwent only placement of a PED, whereas 5 underwent adjunctive coil embolization of at least 1 aneurysm. One PED was used in each of 9 patients, and 2 PEDs were required in each of 8 patients. There were 2 intraprocedural complications; however, in both instances, the patients were asymptomatic at the last follow-up. The follow-up imaging studies were available for 15 patients at a mean of 7 months after treatment (216 days, range 0-540 days). The mean initial Raymond score after treatment was 2.7 ± 0.7, and the mean final score was 1.3 ± 0.7. CONCLUSIONS In this series, the use of flow diversion for the treatment of tandem cerebral aneurysms had an acceptable safety profile, indicating that it should be considered as an effective therapy for this complicated subset of patients. Further prospective studies must be performed before more definitive conclusions can be made.

Abstract
OBJECTIVE To assess technical success and clinical and imaging outcomes of flow diversion (FD) treatment of multiple, tandem intracranial aneurysms. METHODS Retrospective analysis was performed of patients treated with FD for tandem intracranial aneurysms. RESULTS Twenty female patients with a mean (±SD) age of 60 (±12) years were included. One patient was treated after subarachnoid hemorrhage. In 22 separate procedures, 47 aneurysms, all located in the intracranial internal carotid artery, were treated. In 3 cases, treatment was performed for aneurysm recurrence after previous endovascular treatment. All aneurysms were successfully treated in 1 session. A single stent was used in most (82%) cases, with no adjunctive coiling. There were no intraprocedural complications. Three patients experienced mild, transient neurologic symptoms after the procedure with no long-term neurologic deficits. Follow-up imaging with digital subtraction angiography and/or contrast-enhanced magnetic resonance angiography was available in 18/20 (90%) patients at an average (±SD) of 18.8 (±11.2) months. Of 40 aneurysms with follow-up imaging, 34 (85%) were completely occluded. Clinical follow-up, available in 20/20 (100%) patients, showed that 19/20 (95%) achieved a modified Rankin Scale score of 0-2. There were no cases of aneurysm rupture after treatment, and no patients required retreatment at last available follow-up. CONCLUSIONS FD appears technically feasible, safe, and effective for treatment of tandem intracranial aneurysms, with potential advantages over traditional endovascular or surgical treatment modalities. Larger studies are needed to confirm these findings.

Abstract
BACKGROUND AND PURPOSE Tandem aneurysms are defined as multiple aneurysms located in close proximity on the same parent vessel. Endovascular treatment of these aneurysms has rarely been reported. Our aim was to evaluate the safety and efficacy of a single Pipeline Embolization Device for the treatment of tandem aneurysms of the internal carotid artery. MATERIALS AND METHODS A retrospective analysis of consecutive aneurysms treated with the Pipeline Embolization Device between 2009 and 2016 at 3 institutions in the United States was performed. Cases included aneurysms of the ICA treated with a single Pipeline Embolization Device, and they were divided into tandem versus solitary. Angiographic and clinical outcomes were compared. RESULTS The solitary group (median age, 58 years) underwent 184 Pipeline Embolization Device procedures for 184 aneurysms. The tandem group (median age, 50.5 years) underwent 34 procedures for 78 aneurysms. Aneurysms were primarily located along the paraophthalmic segment of the ICA in both the single and tandem groups (72.3% versus 78.2%, respectively, P = .53). The median maximal diameters in the solitary and tandem groups were 6.2 and 6.7 mm, respectively. Complete occlusion on the last angiographic follow-up was achieved in 75.1% of aneurysms in the single compared with 88.6%% in the tandem group (P = .06). Symptomatic thromboembolic complications were encountered in 2.7% and 8.8% of procedures in the single and tandem groups, respectively (P = .08). CONCLUSIONS Tandem aneurysms of the ICA can be treated with a single Pipeline Embolization Device with high rates of complete occlusion. While there appeared to be a trend toward higher thromboembolic complication rates, this did not reach statistical significance.

Abstract
OBJECTIVE Postoperative visual outcomes following repair of unruptured paraclinoid aneurysms (UPAs) are not well defined. We aim to investigate the influence of treatment modality on visual function. METHODS A systematic literature analysis using the Ovid Medline and EMBASE databases was performed, encompassing English language studies (published between 1996 and 2016) reporting treatment outcomes for UPAs. Rates of visual morbidity (new, permanent postoperative deficit, worsening preoperative deficit); angiographic (occlusion, recurrence, retreatment) and clinical outcomes (death, disability, post-treatment subarachnoid hemorrhage) were recorded. Random effects meta-analysis was performed. RESULTS Twenty-eight studies reported visual outcomes, with data for 1013 endovascular and 691 microsurgical patients. In patients with normal vision undergoing elective repair of UPAs, rates of postoperative visual morbidity were higher following microsurgical (10.8%; 95% confidence interval [CI] 8.5-13.7) than endovascular (2.0%; 95% CI 1.2-3.2) interventions, P < 0.001. In those presenting with preoperative visual impairment, surgery was associated with a modest advantage in visual recovery compared with endovascular therapies (65.2% vs. 48.9%, P < 0.03). There were no differences in visual morbidity following treatment with any of the endovascular modalities. Meta-analysis of comparative studies suggested a trend toward poor visual (ES = 0.42; 95% CI 0.08-2.09) and clinical outcomes (ES = 0.57; 95% CI 0.07-4.44) following microsurgery and a trend toward angiographic recurrence (ES = 2.52; 95% CI 0.80-7.90) and retreatment (ES = 1.62; 95% CI 0.46-5.67) after endovascular interventions. CONCLUSION In patients with normal vision undergoing repairs for UPAs, there is a positive correlation between visual outcomes and endovascular treatments. When visual compromise is present, surgery provided modest advantage in visual recovery. However, definitive conclusions were not possible due to data heterogeneity.

Comparison of Stent-Assisted Coil Embolization and the Pipeline Embolization Device for Endovascular Treatment of Ophthalmic Segment Aneurysms: A Multicenter Cohort Study. World Neurosurg 2017; 105:206-212. [PMID: 28559080 DOI: 10.1016/j.wneu.2017.05.104] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2017] [Revised: 05/17/2017] [Accepted: 05/18/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND Stent-assisted coil embolization and flow diversion with the Pipeline embolization device (PED) are both effective endovascular treatment options for ophthalmic segment aneurysms (OSAs) of the internal carotid artery. Here we present a large comparative cohort study. METHODS A multicenter, retrospective cohort comparison study of consecutively treated OSAs was conducted at 2 academic institutions in the United States comparing stent-coiling (between 2007 and 2015) and PED (between 2011 and 2016). RESULTS A total of 62 of OSAs were treated with stent-coiling and 106 were treated with the PED. The stent-coiling-treated aneurysms were larger, although the maximum diameter was not significantly different between the 2 groups (P = 0.05). The median duration of follow-up was 22.5 months for the stent-coiling group and 8.7 months for the PED group (P = 0.0002). Complete occlusion at last follow-up was achieved in 75.9% of aneurysms in the stent-coiling group and in 81.1% of aneurysms in the PED group (P = 0.516). The retreatment rate was higher with stent-coiling, but the difference did not reach statistical significance (P = 0.062). A good functional outcome was achieved in 96.6% of patients in the stent-coiling group and in 94.7% of those in the PED group (P = 0.707). The rate of neurologic complications was 4.8% in the stent-coiling group and 9.4% in the PED group (P = 0.376). CONCLUSION Stent-coiling and the PED were equally effective for treating OSAs. There were no significant differences in terms of procedural complications, angiographic, functional, and visual outcomes. PED may be more favorable for multiple adjacent OSAs.

Abstract
BACKGROUND Aneurysms of the cerebral vessels are relatively common and aneurysms of the ophthalmic segment of the internal carotid artery (ICA) represent approximately 10% of intradural aneurysms. ANATOMICAL ASPECTS The ophthalmic segment of the ICA extends from the origin of the ophthalmic artery to the origin of the posterior communicating artery. Aneurysms can originate from the ophthalmic artery itself or directly from the ICA at a distance from the ophthalmic artery. The various anatomic configurations can alter the risks of treatment. SURGICAL TREATMENT Surgical treatment of aneurysms of the ophthalmic segment poses unique challenges for the neurosurgeon, given the deep location and complex nearby structures and optic nerve. The necessity to remove the clinoid process can make the operation technically challenging. ENDOVASCULAR TREATMENT Endovascular treatment of paraophthalmic aneurysms includes coil occlusion, and also stent- or balloon-assisted coil occlusion. More recently, hemodynamically active flow diverter stents improved the treatment results. CONCLUSION The management of paraophthalmic aneurysms is associated with specific risks. Careful consideration of the available techniques is necessary before each invention. Coil-occlusion remains the first choice for ruptured paraophthalmic aneurysms. For unruptured paraophthalmic aneurysms flow diversion offers improved results. The overall complication rates of these procedures are low; however, cerebral ischemia, intracranial hemorrhage and visual complications must be considered in advance and the patient must be informed of the risks.

Abstract
OBJECTIVE To review the literature on flow-diverting device (FDD) treatments for intracranial aneurysms (IAs) and to compare the safety and efficacy of FDDs with coil embolization treatment (CET) for IAs using a meta-analysis of published studies. METHODS A systematic electronic search was conducted of PubMed, Springer Link, EBSCO, and the Cochrane Database on all accessible published articles through September 2015. Abstracts, full-text manuscripts, and the reference lists of retrieved articles were analyzed. Studies that explicitly compared FDD and CET approaches to the treatment of IAs were included. Odds ratios (ORs) and 95% CIs were calculated for the complete occlusion rate and the morbidity rate using a random-effects model. RESULTS Nine studies were included in the analysis, containing retrospectively collected data for 863 patients. FDD treatment showed a significantly higher complete occlusion rate than CET (OR = 3.13; 95% confidence interval [CI], 2.11-4.65) and the subgroup of stent-assisted coiling did (OR = 2.08; 95% CI, 1.34-3.24). FDDs did not achieve a significantly lower overall morbidity rate compared with CET (OR = 0.87; 95% CI, 0.45-1.69) or the SAC (stent-assisted coiling) subgroup (OR = 0.86; 95% CI, 0.33-2.26), and our results did not show a significant difference in mortality between the two techniques. CONCLUSIONS FDD treatment of IAs yielded satisfactory results in complete occlusion rate compared with CET. The FDD procedure is feasible and has no significant difference in morbidity risk. Despite the findings reported herein, further validation with well-designed, multicenter randomized controlled trials is needed.

Abstract
BACKGROUND Flow-diverter devices (FDDs) are new-generation stents placed in the parent artery at the level of the aneurysm neck to disrupt the intra-aneurysmal flow thus favoring intra-aneurysmal thrombosis. OBJECTIVE The objective of this review article is to define the indication and results of the treatment of intracranial aneurysms by FDD, reviewing 18 studies of endovascular treatment by FDDs for a total of 1704 aneurysms in 1483 patients. METHODS The medical literature on FDDs for intracranial aneurysms was reviewed from 2009 to December 2014. The keywords used were: "intracranial aneurysms," "brain aneurysms," "flow diverter," "pipeline embolization device," "silk flow diverter," "surpass flow diverter" and "FRED flow diverter." RESULTS The use of these stents is advisable mainly for unruptured aneurysms, particularly those located at the internal carotid artery or vertebral and basilar arteries, for fusiform and dissecting aneurysms and for saccular aneurysms with large necks and low dome-to-neck ratio. The rate of aneurysm occlusion progressively increases during follow-up (81.5% overall rate in this review). The non-negligible rate of ischemic (mean 4.1%) and hemorrhagic (mean 2.9%) complications, the neurological morbidity (mean 3.5%) and the reported mortality (mean 3.4%) are the main limits of this technique. CONCLUSION Treatment with FDDs is a feasible and effective technique for unruptured aneurysms with complex anatomy (fusiform, dissecting, large neck, bifurcation with side branches) where coiling and clipping are difficult or impossible. Patient selection is very important to avoid complications and reduce the risk of morbidity and mortality. Further studies with longer follow-up are necessary to define the rate of complete occlusion.

Abstract
OBJECTIVE Unruptured paraophthalmic aneurysms present unique challenges, and the ideal management remains unknown. METHODS We performed a pooled analysis of single-center experiences to compare the risks and effectiveness involving patients with unruptured paraophthalmic aneurysms treated with clipping, coiling alone, stent-assisted coiling, and flow-diversion. The MEDLINE database was searched and thirty-three series (including our institutional experience) were included. RESULTS Clipping caused more intracranial hemorrhage (ICH) and neurologic complications (NCs) than coiling alone (ICH: odds ratio [OR] = 3.058, P = 0.013; NC: OR = 5.809, P < 0.001), stent-assisted coiling (ICH: P = 0.018; NC: OR = 7.367, P < 0.001), and flow-diversion (ICH: P = 0.006; NC: OR = 16.954, P < 0.001). Clipping also caused more unfavorable visual outcomes than both coiling alone (OR = 3.037, P = 0.001) and stent-assisted coiling (OR = 6.055, P = 0.005). Clipping resulted in a lower reoperation rate than coiling alone in large/giant aneurysm group, which approached statistical significance (OR = 0.133, P = 0.057). Clipping, stent-assisted coiling, and flow-diversion all showed higher occlusion rates compared with coiling alone (OR [clipping vs. coiling alone] = 2.852, P ≤ 0.001; OR [coiling alone vs. stent-assisted coiling] = 0.302, P = 0.003; OR [coiling alone vs. flow-diversion] = 0.400, P = 0.013). Flow-diversion showed comparative complication rate, clinical outcomes, and angiographic result compared with stent-assisted coiling. No significant differences were found among all 4 treatment modalities on mortality and poor outcome. CONCLUSIONS Endovascular therapies have benefits over surgical clipping in terms of fewer intracranial hemorrhage complications, fewer NCs, and lower unfavorable visual outcome rate. Flow diversion showed comparative safety and effectiveness to stent-assisted coiling, and they both achieved better radiologic results than coiling alone. Further validation by randomized cohort studies is still needed to provide robust evidence.

Stepwise stent deployment technique for tandem intracranial aneurysms: a review of 21 cases. Eur Radiol 2015; 26:351-8. [PMID: 26007603 DOI: 10.1007/s00330-015-3823-z] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2015] [Revised: 04/13/2015] [Accepted: 04/22/2015] [Indexed: 10/23/2022]
Abstract
OBJECTIVES We performed this study to report our experience using a stepwise stent deployment technique for the treatment of tandem intracranial aneurysms. METHODS Patients with intracranial tandem aneurysms that were treated with a stepwise stent deployment technique between May 2009 and June 2013 were retrospectively reviewed. RESULTS Twenty-one patients with 42 tandem aneurysms were identified (11 men, 10 women), with a mean age of 53.7 years (range, 17-82 years). Subarachnoid haemorrhage was confirmed in 12 patients using computed tomography at onset. Complete occlusion was achieved in 20 of the aneurysms (47.6%) after the procedure, neck remnant in 9 (21.4%), and aneurysm remnant in 13 (31.0%). The perioperative complications included in-stent thrombosis in one case and vasospasm in two cases, none of which left a permanent neurological deficit. The modified Rankin Scale (mRS) score at discharge was 0-2 in 20 cases and 3 in one case. The follow-up angiograms available for 17 patients showed complete occlusion in 26 aneurysms, improved in 4, and stable in 4. All of the patients had mRS scores of 0-1 during the clinical follow-up period. CONCLUSIONS The stepwise stent deployment technique is feasible and helpful in the treatment of intracranial tandem aneurysms. KEY POINTS • Treating wide-necked intracranial aneurysms with stent-assisted coiling is preferable. • Tandem wide-necked intracranial aneurysms can be treated with a single stent. • Stepwise stent deployment is technically feasible for embolizing tandem intracranial aneurysms.
