BackgroundFlow diversion represents a novel but definitive treatment for recurrent and difficult-to-coil aneurysms of the anterior communicating artery (ACoA) region, of which reports are limited.ObjectiveTo determine the effectiveness of the Pipeline embolization device (PED) in treating aneurysms in the ACoA region.MethodsWe retrospectively reviewed an IRB-approved database of patients with an aneurysm at a single institution for patients with ACoA or A1–A2 aneurysms treated with PED. Data analyzed included demographics, aneurysm characteristics, procedural details, follow-up results, and outcomes.ResultsA total of 50 procedures were performed on 41 patients, including seven patients who underwent bilateral ‘H-pipe’ PED placement. The average age was 56 years and 46% of the patients were female. The average aneurysm size was 4.5 mm, and two large (>10 mm) aneurysms were treated. The vessel of origin was either the ACoA (26 aneurysms, 63%) or the A1–A2 junction (15 aneurysms, 37%). Eighteen patients (44%) had prior subarachnoid hemorrhage and 20 had previously been treated either with clipping (6 aneurysms, 15%) or coiling (14 aneurysms, 34%). Procedural success was achieved in 48/50 cases (96%) and two cases were aborted. Coils were deployed adjunctively in two cases (4%). Procedural outcomes included no deaths, one major ischemic stroke (2%), and two patients with intracranial hemorrhage (4%). Complete aneurysm occlusion was achieved in 81% of patients at 6 months and 85% of patients at last follow-up digital subtraction angiography.ConclusionsThe PED can be used safely and effectively in the treatment of aneurysms of the ACoA region. This represents a good alternative treatment option to microsurgical clipping and endovascular coiling.

Abstract Background Aneurysmal subarachnoid hemorrhage (SAH) is a kind of destructive cerebrovascular disease which could affect people's cognition, even the life expectancy. People with SAH are considered in a fatal situation, especially in the young population. This study aimed to investigate cognitive impairment and related factors in young patients with ruptured anterior communicating artery (ACoA) aneurysms.Methods We conducted a multicentre retrospective follow-up study at three hospitals in China. The young patients (18-50 years) who underwent ruptured ACoA aneurysm treatment by microsurgical clipping or endovascular coiling at three academic institutions in China from January 2015 to November 2017 were recruited. Patient cognition and life quality were assessed by using modified Telephone Interview for Cognitive Status (TICS-m), the modified Rankin Scale (mRS), and the instrumental activities of daily living (IADL) scale 2. Multiple cox-regression analysis was used to identify variables independently associated with cognitive impairment.Results Of the total of 59 patients, 54 (91.5%) achieved good clinical outcomes (mRS score 0-2) and 51 (86.4%) had excellent quality of life (IADL score 8). Ten (16.9%) patients showed cognitive impairments (TICS-m<27). The multivariate COX regression analysis showed that mRS scores of 3-5 at discharge, female sex, and aneurysm size <5 mm was independently associated with cognitive impairment. TICS-m scores at the latest follow-up were similar after open surgery and coiling. Conclusion In this relatively young sample that excluded patients with very poor-grade SAH or serious complications, microsurgical clipping led to better clinical outcomes than endovascular coiling, while cognitive outcomes were similar across treatment modalities. These results are not completely consistent with previous studies, and should therefore be considered in the clinical practice as well as further investigated in larger patient samples.

OBJECTIVEThe utilization of the Pipeline embolization device (PED) has increased significantly since its inception and original approval for use in large, broad-necked aneurysms of the internal carotid artery. While microsurgical clipping and advances in endovascular techniques have improved overall efficacy in achieving complete occlusion, recurrences still occur, and the best modality for retreatment remains controversial. Despite its efficacy in this setting, the role of PED utilization in the setting of recurrent aneurysms has not yet been well defined. This study was designed to assess the safety and efficacy of PED in the recurrence of previously treated aneurysms.METHODSThe authors reviewed a total of 13 cases in which patients underwent secondary placement of a PED for aneurysm recurrence following prior treatment with another modality. The PEDs were used to treat aneurysm recurrence or residual following endovascular coiling in 7 cases, flow diversion in 2, and microsurgical clipping in 4. The mean time between initial treatment and retreatment with a PED was 28.1 months, 12 months, and 88.7 months, respectively. Clinical outcomes, including complications and modified Rankin Scale (mRS) scores, and angiographic evidence of complete occlusion were tabulated for each treatment group.RESULTSAll PEDs were successfully placed without periprocedural complications. The rate of complete occlusion was 80% at 6 months after PED placement and 100% at 12 months in these patients who underwent PED placement following failed endovascular coiling; there were no adverse clinical sequelae at a mean follow-up of 26.1 months. In the 2 cases in which PEDs were placed for treatment of residual aneurysms following prior flow diversion, 1 patient demonstrated asymptomatic vessel occlusion at 6 months, and the other exhibited complete aneurysm occlusion at 12 months. In patients with aneurysm recurrence following prior microsurgical clipping, the rate of complete occlusion was 100% at 6 and 12 months, with no adverse sequelae noted at a mean clinical follow-up of 27.7 months.CONCLUSIONSThe treatment of recurrent aneurysms with the PED following previous endovascular coiling, flow diversion, or microsurgical clipping is associated with a high rate of complete occlusion and minimal morbidity.

Introduction: The authors present the analysis of the microsurgical clipping of 100 cerebral aneurysms of the anterior circulation and compare the series data with the literature. Methods: Eighty-eight patients presenting with 100 anterior circulation aneurysms operated on microsurgical techniques between 2002 and 2008 by the first author (CES) were retrospectively reviewed. Results: A total of 88 patients with 100 aneurysms of the anterior circulation were treated in a six years period. Fifty eight female (66%) and thirty male (34%) with nine patients (10.2%) presenting with multiple aneurysms. The mean age was 52 years (range from 26 to 76 years). Eighty five percent of the cases were ruptured aneurysms. The mean follow-up was 52.4 months (range from 5 to 76 months). The topography of the aneurysms was distributed as it follows: Anterior communicating artery (ACoA) 25%; posterior communicating artery (p-comm) 29%; middle cerebral artery (MCA) 27%; paraclinoidal aneurysms 8%; pericallosal artery 6% and internal carotid artery (ICA) tip 5%. The mortality was 7.9%, and such cases presenting with Hunt Hess graduation 3 and 4. The permanent morbidity was 4.5%, cases with Hunt Hess graduation 3 and 4. Perioperative rupture occurred in 17% of the cases, only in previous ruptured aneurysms. There was no clinical evidence of rebleeding during the follow-up period of the series. Conclusions: The microsurgical clipping of cerebral aneurysms of the anterior circulation is a safe and curative treatment for most of such lesions. At present, studies suggest evidences of superior results of surgery compared to the endovascular techniques in the rates of total occlusion of the aneurysms, lesser rates of rebleeding of the treated cases. The results of the present series are similar to the rates of the most relevant literature.

Abstract BACKGROUND The extent of obliteration of ruptured intracranial aneurysms treated with coil embolization has been correlated with the risk of rerupture. However, many practitioners consider that a small neck remnant is unlikely to result in significant risk after coiling. OBJECTIVE To report our recent experience with ruptured anterior cerebral artery aneurysms treated with endovascular coiling, which recurred or reruptured, requiring microsurgical clipping for subsequent treatment. METHODS Retrospective review of patients with intracranial aneurysms treated at our institution since August 2018. Patient and aneurysm characteristics, initial and subsequent treatment approaches, and outcomes were reviewed. RESULTS Six patients were included. Out of those 6 patients, 5 patients had anterior communicating artery aneurysms, and 1 patient had a pericallosal aneurysm. All initially presented with subarachnoid hemorrhage (SAH) and were treated with coiling. Recurrence occurred at a median of 7.5 mo. In 2 cases, retreatment was initially performed with repeat endovascular coiling, but further recurrence was observed. Rerupture from the residual or recurrent aneurysm occurred in 3 cases. In 2 cases, the aneurysm dome recurred; in 1 case, rerupture occurred from the neck. All 6 patients underwent treatment with microsurgical clipping. Follow-up catheter angiography demonstrated a complete occlusion of the aneurysm in all cases with the preservation of the parent vessel. CONCLUSION Anterior cerebral artery aneurysms may recur after endovascular treatment, and even small neck remnants present a risk of rerupture after an initial SAH. Complete treatment requires a complete exclusion of the aneurysm from the circulation. Even in cases that have been previously coiled, microsurgical clipping can represent a safe and effective treatment option.

Primary Indication

IntroductionInternal carotid artery termination (ICAT) and proximal A1 aneurysms can be challenging for open surgical clipping or endovascular coiling. Treatment with flow diversion covering the middle cerebral artery (MCA), an end vessel supplying a terminal circulation, has not been reported.MethodsA prospective, Institutional Review Board-approved database was analysed for patients with pipeline embolisation device (PED) placement from the anterior cerebral artery (ACA) to the ICA during cerebral aneurysm treatment.ResultsNine cases were identified, including five proximal A1, three posterior communicating artery and one ICAT aneurysm locations. Average aneurysm size was 8.3 mm (range 3–17), with 67% saccular and 78% right-sided. Primary indication for treatment was significant dome irregularity (44%), recurrence or enlargement (33%), underlying collagen vascular disorder (11%) and traumatic pseudoaneurysm (11%). Preservation of the ipsilateral ACA (with PED placed in A1) was performed when the anterior communicating artery (67%) or contralateral A1 (33%) were absent on angiography. Adjunctive coiling was done in four cases (44%). There was one major stroke leading to mortality (11%) and one minor stroke (11%). Clinical follow-up was 27 months on average. Follow-up digital subtraction angiography (average interval 15 months) showed complete aneurysm obliteration (88%) or dome occlusion with entry remnant (12%). The jailed MCA showed minimal or mild delay (primarily anterograde flow) in 75% of cases and significant delay (reliance primarily on ACA and external carotid artery collaterals) in 25%.ConclusionsCovering the MCA with a flow diverting stent should be reserved for select rare cases. Strict attention to blood pressure augmentation during the periprocedural period is necessary to minimise potential ischaemic compromise.

Introduction: The pipeline embolization device (PED) is increasingly used in the endovascular management of cerebral aneurysms. Longitudinal data regarding safety and benefit of the PED in anterior communicating (ACOM) artery aneurysms are limited and particularly lacking in residual ACOM artery aneurysms. We report the use of the PED in 3 patients with ACOM artery aneurysms who were previously coiled. Methods: Three patients with ACOM artery aneurysms, all previously treated with coiling and with recurrence of the aneurysm neck, were treated with the PED. All obtained follow-up diagnostic cerebral angiograms at either 3 or 6 months. Results: Mean age of patients was 59 years. All patients received cerebral angiograms at a minimum of 3 months after treatment with the PED. Follow-up angiography was performed up to a mean of 10 months at which time point all cases demonstrated complete aneurysm occlusion, without any stenosis in the parent artery. Conclusion: The PED can be safely used for the treatment of ACOM artery aneurysms. Complete aneurysm obliteration can be achieved in cases refractory to endovascular coiling. These findings warrant replication in a larger data set.

BackgroundFlow diversion (FD) has emerged as superior minimally invasive therapy for cerebral aneurysms. However, aneurysms of small peripheral vessel segments have not yet been adequately treatable. More specifically, currently established devices necessitate large microcatheters which impede atraumatic maneuvering. The Silk Vista Baby (SVB), a novel flow diverter, offers the as yet unique feature of deliverability via a 0.017 inch microcatheter. This study reports our first experience with the SVB in challenging intracranial vessels employing a vessel-specific tailored microcatheter strategy.Materials and methods25 patients (27 aneurysms) were prospectively included. A total of 30 SVBs were employed, predominantly targeting demanding aneurysms of the anterior communicating artery complex. The efficacy of the FD was assessed using two-dimensional vector-based perfusion and conventional digital subtraction angiography (DSA) after implantation and at the first follow-up at 3 months. The first follow-up was available in 22 patients.ResultsAll devices were implanted without technical or clinical complications. Eleven treatments were performed using the recommended Headway 17. In 14 interventions the even more maneuverable Excelsior SL10 was used, which was previously tried and tested for safety ’in vitro’ as an alternative delivery system. Aneurysmal influx was strongly reduced after implantation. All parent vessels remained patent. 17/27 aneurysms were completely occluded at first follow-up (∼2.7 months), 6/27 aneurysms showed decreased influx or delayed washout and one remained unchanged. In three cases follow-up DSAs are remaining.ConclusionsSVB provides enhanced controllability in vulnerable segments beyond the circle of Willis. Smaller variants (2.25 mm and 2.75 mm) can safely be implanted via the superiorly navigable Excelsior SL10. Hence, the SVB represents the next evolutionary step in minimally invasive treatment of cerebral aneurysms.

Abstract Introduction: Aneurysmal Subarachnoid Hemorrhage (aSAH) remains a devastating and often fatal form of stroke. The aneurysm is targeted for obliteration to prevent re-bleeding and to manage the possible complications from the event. Endovascular coiling has emerged as a less invasive alternative to conventional surgical clipping to treat aneurysms. Patients and methods: This study was done in 50 cases of anterior communicating (Acommm) aneurysm presented in the department of neurosurgery, SMS medical college, Jaipur from November 2015 to August 2016 to evaluate the outcome of both modalities used in the treatment of ruptured Acommm aneurysm. 50 patients with Hunt and Hess (H&H) grade I, II or III were classified into two groups of microsurgical clipping and endovascular coiling. Results: Mortality rate was comparable in both groups that were 21. 21% in the clipping group and 23. 52% in the coiling group. Good Glasgow outcome score (GOS) were found in 60. 60% of clipping and 58. 58% of coiling group. All the complications found to be more in clipping group but that were not statistically significant except for hyponatremia which was significantly higher in clipping group(P=0. 007). Conclusion: There was no statistically significant difference in GOS at 6 month of follow up between the two groups. We recommend further interventional studies with larger sample sizes and longer follow up for better evaluation of the modalities.

Brain shifts following microsurgical clip ligation of anterior communicating artery (ACoA) aneurysms can lead to mechanical compression of the optic nerve by the clip. Recognition of this condition and early repositioning of clips can lead to reversal of vision loss.The authors identified 3 patients with an afferent pupillary defect following microsurgical clipping of ACoA aneurysms. Different treatment options were used for each patient. All patients underwent reexploration, and the aneurysm clips were repositioned to prevent clip-related compression of the optic nerve. Near-complete restoration of vision was achieved at the last clinic follow-up visit in all 3 patients.Clip ligation of ACoA aneurysms has the potential to cause clip-related compression of the optic nerve. Postoperative visual examination is of utmost importance, and if any changes are discovered, reexploration should be considered as repositioning of the clips may lead to resolution of visual deterioration.
