Endovascular treatment is a safe and efficient therapy for intracranial aneurysms with lower complication and mortality rates compared to surgical clipping. Wide-neck aneurysms still represent a challenge to complete and safe aneurysm occlusion in spite of techniques such as stent-assisted or balloon-assisted coiling, developed in order to achieve better occlusion rates. These techniques themselves may lead to further complications, so alternative methods such as the dual microcatheter technique were developed. This technique assumes that, via two microcatheters inserted into an aneurysm, simultaneous deployment of two coils achieves a stable coil frame without the use of adjunctive devices. The aim of this paper is to present a successfully treated basilar tip wide-neck aneurysm treated with the dual microcatheter technique.Case report. A 46-year-old male patient with acute onset of severe headache presented in the emergency room with altered state of consciousness. Non-enhanced CT scan showed subarachnoid and intraventricular haemorrhage. CT angiography revealed a wide-neck basilar tip aneurysm. Digital subtraction angiography confirmed the presence of an aneurysm with a wide, 4.9 mm neck.Dual microcatheter technique was chosen as the first treatment option, while a hypercompliant balloon was kept as backup. Two microcatheters were placed inside de aneurysm and two coils were introduced in order to form a stable framing coil mass that served as a support for further coils deployed in an alternately manner through each microcatheter. No procedural complication occurred, and the patient’s evolution was uneventful with no neurological deficits at discharge.Conclusion. The dual microcatheter technique is a safe and effective therapeutic option for wide-neck ruptured or unruptured intracranial aneurysms. Periprocedural complication rates are similar to simple coiling or balloon-assisted coiling, but lower than for stent-assisted coiling.

Background and purposeTo evaluate the safety and effectiveness of the low-profile braided intracranial stents called the Low Profile Visualized Intraluminal Support (LVIS) devices for stent-assisted coil embolization of wide-necked intracranial aneurysms.Materials and methodsThis was a prospective, multicenter, observational study of unruptured and ruptured intracranial aneurysms treated with the LVIS devices. Imaging and clinical data were independently analyzed respectively by CoreLab and Clinical Event Committee. Primary endpoints were clinical safety, effectiveness, and angiographic stability of the results at 6 and 18 months.ResultsTen centers participated in the study; 102 patients were included and 90 patients (42.2% men, 57.8% women) were eventually analyzed, among which 27 (30.0%) had multiple aneurysms. Twenty-three (25.6%) were ruptured aneurysms, four of which (4.4%) were treated in the acute phase. One aneurysm was treated per patient; 92 LVIS and LVIS Jr devices were placed overall. The total aneurysm occlusion rate was 91.0% on immediate post-procedure angiograms, which remained unchanged at 6-month follow-up and was 92.4% at 18-month follow-up. One patient (1.1%) underwent retreatment between 6 and 18 months of follow-up. A modified Rankin score of 0 was documented for most cases immediately after the procedure (86.7%) and at 6-month (86.8%) and 18-month (83.3%) follow-up. The overall permanent morbidity rate at 18 months was 5.6% and the overall rate of events with sequelae related to the stent was 2.2%. The 18-month procedure-related mortality rate was 3.3%. No patient was deemed to require retreatment at 18-month follow-up.ConclusionThe LVIS/LVIS Jr endovascular devices are safe and effective in the treatment of ruptured and unruptured intracranial aneurysms, with acceptable complication rates, very high immediate total occlusion rates, and stable angiographic results.

Background: Unruptured intracranial aneurysms (UIAs) are treated using endovascular treatment or microsurgical clipping. The safety and efficacy of treatments have not been compared in a randomized trial. Methods: We randomly allocated clipping or coiling to patients with 3-25mm UIAs judged treatable both ways. The primary outcome was treatment failure, defined as: initial failure of aneurysm treatment, intracranial hemorrhage or residual aneurysm on one year imaging. Secondary outcomes included neurological deficits following treatment, hospitalization >5 days, overall morbidity and mortality and angiographic results at one year. Results: 136 patients were enrolled from 2010 through 2016 and 134 patients were treated. The one-year primary outcome, available for 104 patients, was reached in 5/48 (10.4% (4.5%-22.2%)) patients allocated surgical clipping, and 10/56 (17.9% (10.0%-29.8%)) patients allocated endovascular coiling (OR: 0.54 (0.13, 1.90), P=0.40). Morbidity and mortality (mRS>2) at one year occurred in 2/48 (4.2% (1.2%-14.0%)) and 2/56 (3.6% (1.0%-12.1%)) patients allocated clipping and coiling respectively. New neurological deficits (15/65 vs 6/69; OR: 3.12 (1.05, 10.57), P=0.031), and hospitalizations beyond 5 days (30/65 vs 6/69; OR: 8.85 (3.22,28.59), P=0.0001) were more frequent after clipping. Conclusions: Surgical clipping led to greater initial treatment-related morbidity than endovascular coiling. At one year, the superior efficacy of clipping remains unproven and in need of randomized evidence.

Object Placement of covered stents has emerged as a promising therapeutic option for cerebrovascular diseases. However, the medium- and long-term efficacy and safety of covered stents in the treatment of these diseases remain unclear. The purpose of this study was to evaluate the medium-term clinical and angiographic outcomes of covered stent placement for the treatment of intracranial aneurysms. Methods The authors' institutional review board approved the study. Thirty-four patients (13 females and 21 males; mean age 41.9 years) with 38 intracranial aneurysms were treated with the Willis covered stent. Clinical and angiographic follow-up were performed at 3 months, at 6–12 months, and annually thereafter. The initial procedural and follow-up outcomes were collected and analyzed retrospectively. Results Forty-two covered stents were successfully implanted into the target artery in 33 patients with 37 aneurysms, and 1 covered stent navigation failed in 1 patient. A complete aneurysm exclusion was initially achieved in 24 patients with 28 aneurysms, and a minor endoleak occurred in 9 patients with 9 aneurysms. Postoperatively, 2 patients died of complications related to the procedure. Angiographic and clinical follow-up data are available in 30 patients. The angiographic follow-up (17.5 ± 9.4 months [mean ± SD]) exhibited complete occlusion in 28 patients with 31 aneurysms, and incomplete occlusion in 2 aneurysms, with an asymptomatic in-stent stenosis in 3 patients (10%). The clinical follow-up (26.7 ± 13 months [mean ± SD]) demonstrated that 16 patients (53.3%) experienced a full recovery, and 14 patients (46.7%) improved. No aneurysm rupture, thromboembolic events, or neurological deficits resulting from closure of a perforating vessel by covered stent placement occurred. Conclusions Endovascular reconstruction with the Willis covered stent represents a safe, durable, and curative treatment option for selected intracranial aneurysms, yielding an excellent medium-term patency of the parent artery and excellent clinical outcomes.

Background and purposeAssisted coiling with stents or balloons enables a higher percentage of complete occlusions of saccular unruptured intracranial aneurysms to be achieved with a reasonable complication rate. The aim of this study was to compare stent-assisted coiling and the balloon remodeling technique in terms of efficacy, stability, and safety for the treatment of comparable unruptured saccular intracranial aneurysms.Materials and methods268 patients with 286 saccular unruptured wide-necked intracranial aneurysms were treated at our institution with stent- or balloon-assisted coiling and retrospectively reviewed. Statistical analysis was performed to assess significant differences between the two groups.ResultsThe rate of complete occlusion at the end of the procedure was higher with stent-assisted coiling than with balloon-assisted coiling (86.8% vs 78%) and the same results were also observed after 6 months (92.1% vs 77.6%; p=0.05). About 50% of major recurrences occurred in large to giant aneurysms (p<0.001). The overall complication rate was similar in the stent-assisted and balloon-assisted groups (10.3% vs 9.3%). Independently of the technique, a higher complication rate was observed with bifurcational aneurysms, particularly in the middle cerebral artery (p=0.016).ConclusionsStent-assisted coiling achieved better results in terms of complete occlusion and stability than balloon-assisted coiling with a lower rate of recurrence without being associated with a higher risk of intraprocedural complications. Bifurcational and large to giant aneurysms were associated with higher complication rates and higher recurrence rates, respectively, and still represent a challenge for both techniques.

Background:The ISAT and ISUIA studies, along with the improvement of endovascular treatment (EVT) have strongly influenced the management of intracranial aneurysms (IAs). We present our experience in the microsurgical treatment of unruptured IAs (UIAs) in this context.Methods:We retrospectively reviewed a consecutive series of non-giant UIAs selected for surgery during a five-year period. Patients and aneurysms characteristics, surgical results and outcome assessed by the Glascow Outcome Scale (GOS) at three month follow-up were studied.Results:Eighty-five patients underwent 93 surgical procedures to obliterate 113 UIAs. Those were incidental in 89% of the cases and mainly located on the middle cerebral artery (65%). Patients were assigned to surgery according to their medical history (young, previous subarachnoid haemorrhage), aneurysm characteristics (wide neck, branch at the neck, “small” size, associated “surgical” aneurysm) or failure of EVT (5%). Operatively, 48% of UIAs had thin wall or blebs and 71% were occluded with one titanium clip. Thrombectomy or temporary clipping were necessary in 4% and 11% of the cases, three aneurysms peroperatively ruptured, four were deemed unclippable, three paraclinoid UIAs had an intracavernous residue and 16% were wrapped because of a small neck remnant (class 2). The mortality rate was 0% and 4% of the patients experienced a definitive major neurological deterioration. Final GOS was unchanged in 96% of the patients.Conclusions:Despite reduction in operative cases and in appropriately selected patients ineligible to EVT, microsurgical clipping of non-giant anterior circulation UIAs can still achieve good outcome with very low mortality and neurological morbidity.

Deep Location

Among posterior circulation aneurysms, basilar tip aneurysm is the most difficult to treat. Because of their deep location in front of the brainstem and their intimate relationship to perforating vessels, morbidity and mortality rates associated with direct exposure used to be daunting. Complex intracranial aneurysms are not uncommonly encountered in cerebrovascular practice. Often their complexity can render standard treatment either impossible or exceedingly hazardous. Although endovascular therapy is an available alternative to surgical clipping, it is not without risks. The Neuroform stent represents a significant advance in the endovascular treatment of intracranial aneurysms. The Y-configured reconstruction method of the Neuroform stent may represent a variable therapeutic option especially in the case of terminal type including bifurcation aneurysms. We report the results of our experience in two small basilar tip aneurysms using stent-assisted coiling.

Abstract BACKGROUND: Treatment of unruptured intracranial aneurysms (UIAs) involves endovascular coiling or aneurysm clipping. While many studies have compared these treatment modalities with respect to various clinical outcomes, few studies have investigated the economic costs associated with each procedure. OBJECTIVE: To determine the reoperation rate, postoperative complications, and inpatient and outpatient costs associated with surgical or endovascular treatment of patients with UIAs in the United States. METHODS: We utilized the MarketScan database to examine patients who underwent surgical clipping or endovascular coiling procedures for UIAs from 2000 to 2009, comparing reoperation rates, complications, and angiogram and healthcare resource use. Propensity score matching techniques were used to match patients. RESULTS: We identified 4,504 patients with surgically treated UIAs, with propensity score matching of 3,436 patients. Reoperation rates were significantly lower in the clipping group compared to the coiling group at 1- (P &lt; .001), 2- (P &lt; .001), and 5 years (P &lt; .001) following the procedure. However, postoperative complications (immediate, 30 and 90 days) were significantly higher in those undergoing surgical clipping. Although hospital length of stay and costs were higher in the clipping group for the index procedure, the number of postoperative angiograms and outpatient services used at 1, 2, and 5 years were significantly higher in the coiling group. CONCLUSION: Though surgical clipping resulted in lower reoperation rates, it was associated with higher complication rates and initial costs. However, overall costs at 2 and 5 years were similar to endovascular coiling due to the significantly higher number of follow-up angiograms and outpatient costs in these patients.

Background Eclipse 2L is a new double lumen balloon microcatheter for neurovascular use, with several design features that separate it from previous generation devices. We aimed to report our initial experience of balloon-assisted coiling of intracranial aneurysms using the Eclipse 2L balloon. Materials and methods Retrospective single-center review of patients who underwent balloon-assisted coiling with the Eclipse 2L balloon, for ruptured or unruptured intracranial aneurysms between 1 June 2016 and 31 December 2018. Cases with adjunctive use of stents and recurrences of previously embolized aneurysms were excluded. Patient files were used to extract aneurysm characteristics, complications, immediate and long-term results. Results We identified 120 patients with 126 aneurysms, of which 83 (65.8%) unruptured. Average aneurysm size was 5.9 mm (standard deviation 3.2 mm), with a dome-to neck-ratio of 1.7 (SD 0.6). Most aneurysms (79.3%) were wide necked. Immediate angiographic exclusion (Raymond-Roy grade I–II) was obtained in 95.1% of cases (81.7% grade I and 13.4% grade II). Procedural morbidity was 3.2% with no procedural mortality. Follow-up imaging was available for 115 aneurysms (91.2%). After an average follow-up period of 8.9 months (SD 7.3 months), 96.5% of aneurysms presented class I–II occlusion. Two aneurysms (1.7%) were retreated during follow-up. Conclusion Balloon-assisted coiling using the Eclipse 2L double lumen balloon is feasible for aneurysms in a wide range of locations in the anterior and posterior circulation. The angiographic results and complication rates compare favorably with previously published studies.

Flow diversion prostheses represent a new endovascular approach aimed at treating patients with large wide-neck aneurysms. Our objective is to present this new technology, to review the clinical studies on efficacy, and to emphasize its current limits. Flow diversion prostheses consist of a cylinder made of a large number of braided microfilaments providing a large metallic surface when deployed and inducing a blood flow diversion outside the aneurysm. Two different brands are currently available. Clinical data supporting their efficacy are currently limited to six non comparative cohort studies that included between 18 and 107 patients. Procedural implantation was shown to be feasible in more than 90% and safe with a thirty-day mortality between 2.8 and 5.5%. Complete occlusion rates at twelve months varied between 85.7 and 100%. Even though promising, the current status of flow diversion prostheses needs further evaluation with randomized, prospective, clinical trials with comparison to conventional strategies including endovascular coiling or surgical clipping.
