“…This trend may explain the relatively low thromboembolic complication rate, but also lower rates of complete occlusion compared with some recently published series on use of adjunctive devices. 26,27 Adjunctive devices have been used in 20.4% of other published MCA series, 22 with the aim of obtaining complete occlusion to minimize the risk for subsequent hemorrhage. 28 A critical appraisal of the available literature has suggested that balloon assistance has a very similar safety profile to coiling without remodeling.…”

“…In endovascular embolization, difficulties may be created by the size of the aneurysm and its neck rather than its location 17 . The introduction of the stent-assisted technique 18 and the development of various soft coils have significantly improved the anatomical results of coil embolization in this kind of aneurysm by permitting tight coil packing and a more complete occlusion of the lesion's inflow. Therefore, an alternative endovascular technique would be of particular benefit in this group of patients.…”

This study evaluated the results of endovascular embolization of multiple intracranial aneurysms. A retrospective hospital chart and radiograph review were made of all patients with multiple intracranial aneurysms seen between March 2010 and January 2011. Ten patients presented with subarachnoid hemorrhage, four with mass effect, two with brain ischemia and twenty were incidental. These 36 patients harbored 84 aneurysms, 63 of which were treated with endovascular techniques, two by surgical clipping, and 19 were left untreated. Of the coil-treated lesions, a complete endovascular occlusion was achieved in 54 aneurysms (85.7%), and eight (12.7%) presented neck remnants with one (1.6%) stented only. Twenty-six patients (72.2%) underwent coil embolization of more than one aneurysm in the first session. Follow-up angiographic studies in 31 patients demonstrated an unchanged or improved result in 93.0% of the aneurysms (53 lesions) and coil compaction in 7.0% (four lesions). The overall clinical outcome was excellent in 33 patients (91.7%), good in one (2.8%) and fair in two (5.5%). Endovascular techniques may be a particularly suitable method for treating multiple intracranial aneurysms.

“…Bifurcation aneurysms are a challenging entity to treat and a wide variety of different coiling methods, including balloon-assisted, stent-assisted and the waffle cone technique have been used to treat these aneurysms [1][2][3][4][5][6][7]. Dedicated devices have recently entered the market that have been designed specifically to assist in the treatment of these aneurysms and include the pCONus1 and pCONus2 (phenox, Bochum, Germany), the PulseRider ® (Pulsar Vascular, Los Gatos, CA, USA), and the eCLIPs™ device (Evasc Neurovascular Enterprises, Vancouver, BC, Canada).…”

Background Recently, numerous devices dedicated to the treatment of wide-necked aneurysms have become available. We present our initial experience with the pCANvas device and present the technical success rate, clinical outcome and immediate angiographic occlusion rates. Objective We sought to determine the efficacy of flow with the pCANvas for the treatment of unruptured intracranial aneurysms. Methods We performed a retrospective review of our prospectively collected data to identify patients treated with the pCANvas device between February 2015 and February 2017. The patient demographics, aneurysm characteristics, immediate and delayed clinical and radiographic follow-up data were recorded. Results We identified 17 patients (13 female) treated only with the pCANvas device. The average age of the patients was 60.5 ± 13.3 years (range 25-75 years). The average dome width was 7.6 ± 3.2 mm (range 3-15.8 mm), dome height 7.1 ± 3.2 mm (range 3-12.9 mm) and neck width 5.4 ± 3.2 (range 3-16.3 mm). The average aspect ratio was 1.5 ± 0.8 (range 0.6-3.7). At the end of the procedure 15 aneurysms continued complete filling of the aneurysm (Raymond Roy Classification[RRC] 3) with 2 aneurysms showing only filling of the neck of the aneurysm (RRC 2). Early follow-up angiography was available for 16 patients and at this stage 11 aneurysms showed persistent and complete filling of the aneurysm (RRC 3), 5 aneurysms showed complete occlusion of the aneurysm (RRC 1) and 7 aneurysms underwent repeat treatment with coiling. Conclusion The early results on the use of the pCANvas are promising; however, longer term follow-up and larger studies are required.
