ABSTRACT BACKGROUND: The prognosis of ischemic anterior circulation intracranial dissection (AC-ICD) is poor and its optimal management is still controversial. OBJECTIVE: To evaluate the safety and efficacy of a self-expanding stent for ischemic AC-ICD. METHODS: Eight patients (mean age, 36 years) underwent self-expanding stenting for ischemic AC-ICD. Imaging findings of ischemic AC-ICD, the reason for stenting, and the clinical and angiographic outcomes were retrospectively evaluated. RESULTS: AC-ICD involved intracranial internal carotid artery to middle cerebral artery (MCA) in 2, intracranial internal carotid artery alone in 3, and MCA alone in 3 patients. Six AC-ICDs showed complete or near occlusions while 2 had a severe degree of stenosis. Six AC-ICDs showed an intimal flap and 3 had intramural hematomas. Six patients underwent emergent stenting for acute stroke within 6 hours (n = 2) or crescendo-type stroke within 24 hours (n = 4), while 2 patients had stenting for recurrent ischemia on dual antiplatelet and/or anticoagulation after the initial attack. The mean dissection-related stenosis improved from 93.1% to 20.3% after stenting (P < .05). The mean National Institutes of Health Stroke Scale score improved from 7.5 to 1.4 (P < .05). All patients had excellent or favorable outcomes at 3 months: modified Rankin Scale score, 0 in 3, 1 in 3, and 2 in 1 patient(s). No patients had subarachnoid hemorrhage or ischemic symptom recurrence during the clinical follow-up (mean, 27 months). All stented arteries were patent without significant in-stent stenosis on angiographic follow-up (range, 3–12 months). CONCLUSION: Self-expanding stents seem to be safe and effective for AC-ICD presenting with acute/crescendo-type stroke or recurrent ischemia despite adequate medication.

Abstract BACKGROUND: Blister aneurysms of the internal carotid artery (ICA) are uncommon. There is a paucity of data on the long-term outcomes of patients. OBJECTIVE: To review our experience with the treatment of these lesions. METHODS: We retrospectively reviewed all aneurysms treated at our institution between 1994 and 2005. Relevant operative notes, radiology reports, and inpatient/outpatient records were reviewed. RESULTS: Seventeen patients (3 male, 14 female) with 18 blister aneurysms of the ICA were identified. The mean age was 44.6 years (range, 17–72; median, 42 years). Twelve patients (70.6%) presented with aneurysmal subarachnoid hemorrhage. The mean admission Glasgow Outcome Scale score was 4.3 (range, 2–5; median, 5). All patients were initially treated using microsurgical technique with direct clipping (n = 15; 83.3%) or clip-wrapping with Gore-Tex (n = 3, 16.7%). There were 4 cases of intraoperative rupture, all associated with attempted direct clipping; all 4 cases were successfully clipped. Two cases rebled post-treatment. Both rebleeding episodes were managed with endovascular stenting. Follow-up angiography was available for 14 patients and revealed a new aneurysm adjacent to the site of clipping in 1 patient and in-stent stenosis in 2. At the mean follow-up of 74.5 months (median, 73; range, 7–165), the mean Glasgow Outcome Scale score was 4.6 (range, 2–5; median, 5). CONCLUSION: Microsurgical treatment of blister aneurysms of the ICA results in excellent outcome. In the evolution of treating these friable aneurysms, we have modified our clip-wrapping technique and use this technique when direct clipping is not feasible.

BackgroundThe pipeline embolization device (PED) is approved for the treatment of large aneurysms of the proximal internal carotid artery (ICA). Its off-label application in treating aneurysms located specifically at the ICA terminus (ICA-T) has not been studied.MethodsWe conducted a retrospective chart review of patients from 2011 to 7 treated with PEDs. Out of 365 patients, 10 patients with ICA-T aneurysms were included. Patient demographics, procedural information, follow-up imaging, and clinical assessments were recorded.ResultsMean age was 46.9 years (± 8.8), and 6 (60%) patients were women. The mean maximum diameter of the aneurysms treated was 14.7 mm (± 10.7) and the mean neck diameter was 9.3 mm (± 6.6). Reasons for presentation included six incidental findings, one acute subarachnoid hemorrhage (SAH), and three patients with prior SAH. Kamran–Byrne Occlusion Scale scores for the treated aneurysms were as follows: three class IV (complete obliteration), four class III (<50% filling in both height and width for fusiform aneurysms or residual neck for saccular aneurysms), one class II fusiform aneurysm, 1 class 0 saccular aneurysm (residual aneurysm body), and one not classified due to pipeline thrombosis. Two clinically asymptomatic complications were noted: one patient who had a small distal cortical SAH post PED and one patient whose stent was found to be thrombosed on follow-up angiogram. All patients were seen in follow-up, and no patients were found to have worsening of their pre-procedure modified Rankin Scale score.ConclusionThe PED has potential for treating ICA-T aneurysms not amenable to conventional treatment strategies. Further studies are warranted to confirm the long term outcomes.

Abstract The natural course of fibromuscular dysplasia (FMD) of the internal carotid artery (ICA). a stenosing angiopathy associated with cerebrovascular insufficiency, has not been described. A search of medical records located 16 female patients with angiographically demonstrated FMD of the ICA. The identical twin of 1 patient was included in the registry on the basis of noninvasive studies consistent with FMD of the ICA. The mean age at diagnosis was 58 years. Follow-up examinations were performed an average of 3.8 years after diagnosis (range, 1 to 9 years); the evaluation included clinical, angiographic, and Doppler studies. Fifteen patients showed no evidence of progression of FMD, whereas 2 patients with coincident atherosclerotic disease had suffered strokes. One patient had undergone surgical dilatation of the ICA. 3 had received oral anticoagulants, and 13 had received either aspirin or no specific therapy. In light of the apparently benign clinical course of uncomplicated FMD of the ICA, it is concluded that dilatation is rarely warranted.

Object Ruptured blood blister–like aneurysms (BBAs) of the internal carotid artery (ICA) are rare but carry a high rate of morbidity and mortality. Furthermore, BBAs are very difficult to treat surgically as well as endovascularly. The authors present their experience in treating BBAs with reconstructive endovascular methods. Methods Nine ruptured BBAs in 9 consecutive patients (2 men and 7 women; mean age 50 years, range 42–57 years) were treated using reconstructive endovascular methods between January 2006 and November 2007. Treatment methods and angiographic and clinical outcomes were retrospectively evaluated. Results All 9 BBAs were initially treated with stent-assisted coil (SAC) embolization. This was followed by a second stent insertion using the stent-within-a-stent (SWS) technique in 3, covered stent placement in 3, and SAC embolization alone in 3. All 3 patients who underwent SWS placement had excellent outcomes (Glasgow Outcome Scale Score 5) with complete angiographic resolution of the BBAs. There were no treatment-related complications in the SWS group. Two of the 3 patients who received covered stents had excellent outcomes (Glasgow Outcome Scale Score 5) and complete occlusion of the BBA was achieved. The remaining patient who received a covered stent died of ICA rupture during the procedure. Aneurysm regrowth without rebleeding occurred in the 3 patients who underwent SAC embolization. Two of the 3 recurrent BBAs were treated with coil embolization with a second stent insertion, and as a result these belonged to the SWS group. The other recurrent BBA was treated with a covered stent. Of the 8 surviving patients, 5 underwent SWS, and 3 underwent covered stent placement. All surviving patients had excellent outcomes during the clinical follow-up period (mean 11 months, range 4–26 months); complete BBA resolution and smooth reconstruction of the affected ICA segment was shown on follow-up angiography. Conclusions In the present study, the SWS and covered-stent techniques effectively prevented rebleeding and regrowth of the BBA without sacrifice of the ICA. The SWS and covered-stent techniques can be considered an alternative treatment option for BBAs in selected patients in whom ICA sacrifice is not feasible. Stent-assisted coiling alone seems insufficient to prevent BBA regrowth.

Object Population-based data on pediatric patients with aneurysms are limited. The aim of this study is to clarify the characteristics and long-term outcomes of pediatric patients with aneurysms. Methods All pediatric patients (≤ 18 years old) with aneurysms among the 8996 aneurysm patients treated at the Department of Neurosurgery in Helsinki from 1937 to 2009 were followed from admission to the end of 2010. Results There were 114 pediatric patients with 130 total aneurysms during the study period. The mean patient age was 14.5 years (range 3 months to 18 years). The male:female ratio was 3:2. Eighty-nine patients (78%) presented with subarachnoid hemorrhage. The majority of the aneurysms (116 [89%]) were in the anterior circulation, and the most common location was the internal carotid artery bifurcation (36 [28%]). The average aneurysm diameter was 11 mm (range 2–55 mm) with 16 giant aneurysms (12%). Eighty aneurysms (62%) were treated microsurgically, and 37 (28%) were treated conservatively due to poor medical and neurological status of the patient or due to technical reasons during the early years of the patient series. No connective tissue disorders common to pediatric aneurysm patients were diagnosed in this series, with the exception of 1 patient with tuberous sclerosis complex. The mean follow-up duration was 24.8 years (range 0–55.8 years). At the end of follow-up, 71 patients (62%) had a good outcome, 3 (3%) were dependent, and 40 (35%) had died. Twenty-seven deaths (68%) were assessed to be aneurysm-related. Factors correlating with a favorable long-term outcome were good neurological condition of the patient on admission, aneurysm location in the anterior circulation, complete aneurysm closure, and absence of vasospasm. Six patients developed symptomatic de novo aneurysms after a median of 25 years (range 11–37 years). Fourteen patients (12%) had a family history of aneurysms. There was no increased incidence for cardiovascular diseases in long-term follow-up. Conclusions Most aneurysms were ruptured and of medium size. Internal carotid artery bifurcation was the most frequent location of the aneurysms. There was a male predominance of pediatric patients with aneurysms. Most patients experienced good recovery, with 91% of the long-term survivors living at home independently without assistance and meaningfully employed. Altogether, almost a third of these patients finished high school and one-fifth had a college or university degree. Pediatric patients had a tendency to develop de novo aneurysms.

This case illustrates the usefulness of an endovascular stent to treat a pseudoaneurysm of the cervical internal carotid artery. A 46-year-old male patient presented with a spontaneous dissection of the cervical internal carotid artery. After failing conservative therapy, he was treated by endovascular placement of a Palmaz stent at level of the pseudoaneurysm and dissection. Immediate obliteration of pseudoaneurysm was achieved, and patency of the internal carotid artery was maintained. The patient sustained no neurological complications and the stenosis of treated carotid artery did not occur during the 6-month follow-up period. For internal carotid artery dissection, stent placement seems to be a reasonable therapeutic alternative to direct surgery.

Background and Purpose: Blood Blister-like aneurysms (BBAs) of the internal carotid artery (ICA) are rare entities of cerebral aneurysms. FD use in acutely ruptured aneurysms, timing of treatment and antiplatelet regimen are main debate topics in clinical practice when the treatment decision is flow diversion. The aim of this study is to report the safety and efficacy of a single-center FD treatment for ruptured BBAs in the early phase of SAH using the SAPT regimen.Material and Method: This study involved a retrospective analysis of a prospectively collected database. Records of patients admitted to our clinic and treated by endovascular route on ruptured BBA between January 2013 and December 2020 were reviewed. Ruptured supraclinoid ICA BBAs treated with FD devices with SAPT within 48 h from ictus of SAH are included. BBA of atypical anatomic locations, other endovascular techniques performed, and delayed admissions (&gt;48 h) were excluded from the study. Demographic, clinical and angiographic features of patients and aneurysms, FD types and numbers, periprocedural complications, immediate and follow-up angiographic and clinical outcomes were recorded.Results: A total of six patients with ruptured BBAs treated via FDs within 48 h and used SAPT were included in the study. The mean age was 41.6 years (range from 34 to 45 years), and four of six patients were female. All patients were treated within 48 h after ictus, and the mean treatment day was 1.33 days. One patient received ticagrelor, and five patients received prasugrel as SAPT for one year after treatment. No procedure-related death and rebleeding were recorded. One (16.7 %) treatment responsive procedure-related complication occurred (transient ischemia). Overall good outcome rate was 83.3%. One patient died due to pneumonia. The immediate control angiograms showed complete occlusions of BBAs in one patient (16.6%). The complete occlusion rate was 100 % for five survivors at the control angiogram. The median follow-up was 49.5 months.Conclusion: This single-center experience suggests that early treatment (&lt;2 days) within SAH of ruptured BBAs with FDs using SAPT is safe and effective in terms of clinical and radiological long-term outcomes.
