Middle Cerebral Artery Aneurysms

Our objective was to study the dynamics of remote results of MCA SA endovascular occlusion. 149 patients with MCA SA were examined and operated, 127 patients were selected for 36 months follow-up, 112 patients in 1 year follow-up, 52 patients were to be examined in 23 years, 17 in 45 years and 14 patients in more than 5 years. Endovascular occlusion was carried out by means of different coils during reconstructive 138 (92.6%) and unplanned deconstructive occlusions 8 (5.4%). For planned deconstructions detachable balloons were used 3 (2%). 17 (11.4%) recurrences were diagnosed and 12 (8%) repeated operations were performed. 19 (12.8%) intra-and postoperative complications/ predictors and 18 (12.1%) complications unrelated to surgery were observed in the first 30 days and only 1 (1.1%) mass effect was identified in 36 months. After our research we were ableto trackthe dynamicsof thepatientslife quality according totheRankinscale; tomonitorthe changes in SA occlusion degree; to define the frequency of recurrences and complications/predictors of complications and to determine the amount of reoperations. We noted a considerable increase in the quantity of total occlusions after reoperations, which resulted in much better filling of the CA cavity, because the prophylaxis of the repeated hemorrhages is the main goal of SA endovascular treatment.

Background The safety and efficacy of the TuBridge flow diverter in treating middle cerebral artery aneurysms remains unknown. In this study, we report our preliminary experience treating complex middle cerebral artery aneurysms using the TuBridge flow diverter. Methods A prospectively maintained database of intracranial aneurysms treated with the TuBridge flow diverter was retrospectively reviewed, and patients with middle cerebral artery aneurysms were included in this study. Demographics, aneurysm features, complications, and clinical and angiographic outcomes were assessed. Evaluation of the angiographic results included occlusion grade of aneurysm (O’Kelly–Marotta grading scale), patency of jailed branch(es), and in-stent stenosis. Results Eight patients with eight middle cerebral artery aneurysms were included in this study. The mean aneurysm size was 11.8 ± 6.8 mm. There were no procedure-related complications and there was no morbidity or mortality at a mean follow-up of 11.3 ± 3.6 months. All patients had follow-up angiograms at a mean of 7.5 ± 4.0 months after surgery. Of the eight patients, there was 1 (12.5%) O’Kelly–Marotta grading scale A, 3 (37.5%) O’Kelly–Marotta grading scale B, 1 (12.5%) O’Kelly–Marotta grading scale C, and 3 (37.5%) O’Kelly–Marotta grading scale D. Of the seven patients with jailed branch, the blood flow of jailed branch was unchanged in 4 (57.1%), decreased in 2 (28.6%), and occluded in 1 (14.3%). In-stent stenosis was mild in 2 (25%) patients and moderate in 1 (12.5%) patient. Conclusion Midterm results suggest that endovascular treatment of middle cerebral artery aneurysms using the TuBridge flow diverter is safe and associated with good outcomes. The TuBridge flow diverter may be an option for complex middle cerebral artery aneurysms that are difficult to treat with either clipping or coiling.

Background Endovascular treatment is an alternative choice for the treatment of distal middle cerebral artery (dMCA) aneurysm, in addition to open surgery; but is still seldom considered. We performed this retrospective study to evaluate the outcome of dMCA in patients. Methods During a period of 10 years, we were able to identify seven patients with a total of eight dMCA aneurysms that were treated endovascularly. They were five men and two women, with a mean age of 36.1 years. All of the aneurysms, including five infectious and three dissecting ones, were treated for the aneurysm and its parent artery’s occlusion, using coils and/or glue. Results The clinical follow-up (9–96 m, mean 36.8 m) showed that they all improved over baseline; except for one patient in whom a mild right hemiparesis remained, after the hematoma evacuation. Angiographic follow-up (7–24 m; mean: 14.6 m) showed that all of them were stable and without the need for recanalization. Conclusions Our data indicated that endovascular treatment is a safe and effective alternative for the treatment of dMCA aneurysms, and should be considered when treating these aneurysms.

OBJECTIVEA direct comparison of endovascular versus microsurgical treatment of ruptured middle cerebral artery (MCA) aneurysms in randomized trials is lacking. As endovascular treatment strategies continue to evolve, the number of reports of endovascular treatment of these lesions is increasing. Herein, the authors report a detailed post hoc analysis of ruptured MCA aneurysms treated by microsurgical clipping from the Barrow Ruptured Aneurysm Trial (BRAT).METHODSThe cases of patients enrolled in the BRAT who underwent microsurgical clipping for a ruptured MCA aneurysm were reviewed. Characteristics of patients and their clinical outcomes and long-term angiographic results were analyzed.RESULTSFifty patients underwent microsurgical clipping of a ruptured MCA aneurysm in the BRAT, including 21 who crossed over from the endovascular treatment arm. Four patients with nonsaccular (e.g., dissecting, fusiform, or blister) aneurysms were excluded, leaving 46 patients for analysis. Most (n = 32; 70%) patients presented with a Hunt and Hess grade II or III subarachnoid hemorrhage, with a high prevalence of intraparenchymal blood (n = 23; 50%), intraventricular blood (n = 21; 46%), or both. At the last follow-up (up to 6 years after treatment), clinical outcomes were good (modified Rankin Scale score 0–2) in 70% (n = 19) of 27 Hunt and Hess grades I–III patients and in 36% (n = 4) of 11 Hunt and Hess grade IV or V patients. There were no instances of rebleeding after the surgical clipping of aneurysms in this series at the time of last clinical follow-up.CONCLUSIONSMicrosurgical clipping of ruptured MCA aneurysms has several advantages over endovascular treatment, including durability over time. The authors report detailed outcome data of patients with ruptured MCA aneurysms who underwent microsurgical clipping as part of a prospective, randomized trial. These results should be used for comparison with future endovascular and surgical series to ensure that the best results are being achieved for patients with ruptured MCA aneurysms.

Abstract BACKGROUND: Middle cerebral artery (MCA) aneurysms are often considered unsuitable for endovascular coiling because of unfavorable morphological features. With improvements in endovascular techniques, several series have detailed the results and complications of endovascular treatment of MCA aneurysms. OBJECTIVE: We performed a systematic review of published series on endovascular treatment of MCA aneurysms including our experience. METHODS: We conducted a computerized MEDLINE search of the literature on endovascular treatment of MCA aneurysms. Only studies examining a consecutive case series of MCA aneurysms were included. We then extracted information regarding intraprocedural complications, procedural mortality and morbidity, immediate and long-term angiographic outcomes, and re-treatment rate. Analysis was done including 40 MCA aneurysms treated at our institution. RESULTS: Twelve studies including our institution's consecutive case series were included. Approximately 50% of the aneurysms presented as ruptured. Intraprocedural rupture rate in unruptured aneurysms was 1.7% (95% confidence interval [CI] = 0.7%-3.6%) compared with 4.8% (95% CI = 3.1%-7.4%) for ruptured aneurysms (P = .02). The risk of early postprocedural hemorrhage was 1.1% (95% CI = 0.5%-2.5%) for ruptured aneurysms. Overall procedure-related permanent morbidity and mortality were 5.1% and 6.0% for unruptured and ruptured aneurysms, respectively. The overall rate of complete or near-complete obliteration at angiographic follow-up was 82.4%. CONCLUSION: Endovascular treatment of MCA aneurysms is feasible and effective in selected cases. The combined periprocedural mortality and morbidity is not negligible (5.1%) and the overall rate of complete or near-complete angiographic obliteration at follow-up approaches 82%.

Abstract BACKGROUND: Bifurcation middle cerebral artery (MCA) aneurysms with wide neck are amenable to endovascular coiling with pCONus stent, a recent device dedicated to wide-neck bifurcation intracranial aneurysms. OBJECTIVE: To evaluate the 1-year angiographic follow-up of wide-neck MCA aneurysms treated with pCONus. METHODS: Forty MCA aneurysms (mean dome size, 7.7 mm; mean neck size, 5.6 mm) coiled with pCONus were retrospectively evaluated. “Recanalization” was defined as worsening, and “progressive thrombosis” was defined as improvement on the Raymond scale. RESULTS: Angiographic midterm (mean, 11.9 months; range, 3-20) follow-up was obtained in all aneurysms. Retreatment was performed in 9 aneurysms (22.5%) without clinical complications, and postoperative angiographic outcome included 2 complete occlusions and 7 neck remnants. Six aneurysms were followed after retreatment (mean, 8.8 months), and presented complete occlusion in 1 case, neck remnant in 4 cases, and aneurysm remnant in 1 case. Among the 31 aneurysms, follow-up showed complete occlusion in 67.7% (21/31), neck remnants in 29% (9/31), and aneurysm remnants in 3.3% (1/31). Adequate aneurysm occlusion (total occlusion and neck remnant) was obtained in 96.7% (30/31). Among these 31 aneurysms, improvement of the rate of occlusion was observed in 15 aneurysms (48.4%), and recurrence in 2 aneurysms (6.5%). There was no 1-year angiographic recurrence of 3- or 6-month totally occluded aneurysms. CONCLUSION: pCONus stent allows a safe coiling of wide-neck MCA aneurysms usually considered as surgical with a low recanalization rate for those adequately occluded at 3 to 6 months. Angiographic results improve over time due to progressive aneurysm thrombosis in around 50% of cases.

Middle Cerebral Artery Aneurysms

Abstract BACKGROUND: Since the International Subarachnoid Aneurysmal Trial, endovascular coiling has been increasingly used as primary treatment option for ruptured or unruptured aneurysms that are feasible for coiling. OBJECTIVE: To evaluate the feasibility and clinical and angiographic outcomes of coiling for unruptured middle cerebral artery aneurysms. METHODS: The records of 70 consecutive patients with 76 unruptured middle cerebral artery aneurysms who underwent coiling were retrospectively evaluated. RESULTS: Thirty-one aneurysms were treated by single-catheter, 18 by multicatheter, 11 by balloon-assisted, 13 by stent-assisted, and 3 by a combination of multicatheter and balloon-assisted techniques. Coiling was accomplished in 75 but failed in 1 aneurysm. One patient died of consequences of subarachnoid hemorrhage occurring 9 hours after coiling. One intraprocedural aneurysm rupture occurred, which was controlled by further coil insertions and left no sequelae. There were 1 cortical infarction and 1 basal ganglia infarction, both of which recovered completely. Treatment-related permanent morbidity and mortality rates were 0% and 1.4%, respectively. Postembolization control angiography revealed 40 complete, 30 neck remnant, and 5 incomplete occlusions. Clinical follow-up was available in all patients (mean, 25 months; range, 7-105 months). There was no subarachnoid hemorrhage during follow-up, but 1 death resulting from acute myocardial infarction occurred 3 months after coiling. None of the surviving patients had any neurological deterioration. Follow-up angiography was available in 69 aneurysms at 6 to 24 months (mean, 12 months). Three major and 6 minor recurrences were detected. All 3 major recurrent aneurysms were re-treated by coiling without any complications. CONCLUSION: Most unruptured middle cerebral artery aneurysms could be safely treated by coiling with acceptable short-term to midterm outcomes. Our results warrant further study with a longer follow-up period in a larger population.
