“…Although these complication rates for SACP in ruptured aneurysms are higher than those reported for SACP in unruptured aneurysms (14)(15)(16), they are similar to those of balloon-assisted coil placement (17) and, according to some prior literature, even NEURORADIOLOGY: Stent-assisted Coil Placement for Acutely Ruptured Wide-necked Intracranial Aneurysms Yang et al Table 1 Potential (10) 47 (90) 2 (4) 50 (96) 0 (0) 52 (100) 7 (13) 45 (87) Women 12 (8) 147 (92) 7 (4) 152 (96) 4 (3) 155 (97) 23 (14) 136 (86) Hunt (8) 178 (92) 9 (5) 185 (95) 4 (2) 190 (98) 29 (15) 165 (85) Grade IV-V 1 (6) 16 (94) 0 (0) 17 (0) 0 (0) 17 (100) 1 (6) 16 ( (18) 37 (82) 4 (9) 41 (91) 0 (0) 45 (100) 12 (27) 33 (73) Middle cerebral artery (MCA) bifurcation 2 (20) 8 (80) 2 (20) 8 (80) 0 (0) 10 (100) 4 (40) 6 …”

Purpose:To evaluate the safety and angiographic and clinical outcome of stent-assisted coil placement (SACP) for acutely ruptured wide-necked intracranial aneurysms treated in a single center during an 11-year period. Materials and Methods:According to an institutional review board-approved protocol, the angiographic and clinical data of 211 patients (52 men, 159 women; median age, 56 years; age range, 31-83 years) with acutely ruptured wide-necked intracranial aneurysms (neck . 4 mm and/or dome-to-neck ratio  2) treated with SACP from September 2000 to December 2011 were reviewed retrospectively. Baseline characteristics, procedure-related complications, angiographic follow-up results, and clinical outcome were analyzed statistically. A Mann-Whitney U test was performed for non-normally distributed continuous variables. A Pearson x 2 or Fisher exact test was performed for categorical variables. Univariate analysis and logistic regression analysis were performed to determine the association of procedure-related complications and clinical outcome with potential risk factors. Results:Procedure-related complications occurred in 30 patients (14.2%). They were more common in the anterior communicating artery (26.7%, 12 of 45) and middle cerebral artery bifurcation (40%, four of 10) aneurysms than in aneurysms at other locations (9.0%, 14 of 156). Clinical outcome (median, 33 months) was good in 175 patients (82.9%) with a modified Rankin Scale score of up to 2. Older age (P = .013, odds ratio = 1.054) and higher Hunt and Hess grade (P , .001, odds ratio = 15.876) were independent risk factors for unfavorable outcome. One hundred fifty-two of 190 patients who survived (80%) underwent angiographic follow-up at least once (median, 12 months). The complete occlusion rate improved from an immediate 45.5% to 75.7% at follow-up (115 of 152 patients). Conclusion:Angiographic and clinical outcomes in our series were comparable to those reported by using coil placement alone or balloon-assisted coil placement techniques. SACP for the treatment of acutely ruptured middle cerebral artery bifurcation and anterior communicating artery aneurysms was associated with a significantly higher incidence of complications than was the case for treatment of aneurysms at other locations.q RSNA, 2015

“…1 The number of cases of coil embolization for aneurysms is increasing, and the stent-protection technique has widened the applicability to cases that had been otherwise difficult to treat with conventional coil embolization. 2 Nevertheless, there is a risk of coil compaction or in-stent restenosis after stent-assisted coil embolization. X-ray digital subtraction angiography is the optimal technique used to examine these adverse events, and it is commonly used as a follow-up tool after using an intracranial stent.…”

BACKGROUND AND PURPOSE:Blood flow in an intracranial stent cannot be visualized with 3D time-of-flight MR angiography owing to magnetic susceptibility and radiofrequency shielding. As a novel follow-up tool after stent-assisted coil embolization, we applied MRA by using a Silent Scan algorithm that contains an ultrashort TE combined with an arterial spin-labeling technique (Silent MRA). The purpose of this study was to determine whether Silent MRA could visualize flow in an intracranial stent placed in the anterior circulation.

“…We have developed a new swine terminal-type aneurysm model that maintains its patency for 3 months [9], which we intend to use for mid-and long-term studies. Moreover, several endovascular approaches are now available for the treatment of intracranial aneurysms, including standard coiling, balloon-assisted coiling, stent-assisted coiling, and flow diversion [20][21][22]. We are also mindful that consideration should be given to establishing the influence of these device choices on endothelialization of wide neck-type and low packing attenuation aneurysms.…”
