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.

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 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.

Purpose: To report several cases illustrating the feasibility and mid-term efficacy of deploying a self-expanding stent-graft to treat traumatic ruptures, pseudoaneurysms, and a spontaneous dissection of the internal carotid artery (ICA). Case Reports: One patient suffered a stab wound and another developed a large pseudoaneurysm years after a gunshot to the neck. The third patient presented with a spontaneous rupture in the setting of fibromuscular dysplasia, and the final patient developed a pseudoaneurysm following carotid endarterectomy in an irradiated neck. All 4 patients were successfully treated with Wallgrafts deployed in the ICA using either an open carotid (first 3 cases) or percutaneous approach (fourth patient). There were no adverse neurological events. During a mean 16-month follow-up (range 6–24), duplex ultrasound and CT scanning found no evidence of restenosis, occlusion, or persistent perfusion of the pseudoaneurysm, which was noted to decrease in all cases. Conclusions: The thin-walled fabric of the Wallgraft appears capable of completely excluding the pseudoaneurysm, resulting in decreased aneurysm size overtime.

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 &lt; .05). The mean National Institutes of Health Stroke Scale score improved from 7.5 to 1.4 (P &lt; .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.

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.

Purpose The diagnosis of carotid artery fibromuscular dysplasia is usually made with conventional angiography performed to evaluate a suspected carotid stenosis. The ultrasound findings with fibromuscular dysplasia have not been well described. This study was performed to assess the characteristics of carotid artery fibromuscular dysplasia with duplex ultrasonography. Methods The hospital records for all patients who had carotid duplex ultrasonography were reviewed from January 2000 to October 2003. Patients with findings suspicious for fibromuscular dysplasia formed the basis of this study. The patient demographics, their presenting symptoms, and ultrasound findings were analyzed. Results Carotid duplex studies were performed on 9157 patients during the study period. The presumptive diagnosis of fibromuscular dysplasia was made in 13 female patients (1.2%), with a mean age of 67 ± 10 years (range, 52-79 years). Patients were referred for asymptomatic carotid bruits ( n = 10, 77%) or transient ischemic attack ( n = 3, 23%). Both mid and distal internal carotid artery involvement were seen in five patients (38%), whereas eight patients (62%) had disease isolated to the distal internal carotid artery. Bilateral carotid artery involvement occurred in eight patients (62%). A consistent finding in all patients was multiple areas of alternating focal thickening with thin, dilated arterial walls. Other sonographic findings included velocity increases (mean, 181 cm/sec; range, 135-318 cm/sec), color flow disturbance, and scarcity of plaque in the suspected arterial segment. Magnetic resonance angiography or carotid angiography was performed on seven (54%) patients, confirming the ultrasound diagnoses. One symptomatic patient was successfully treated with open graduated endoluminal dilatation. One patient with asymptomatic carotid bruit underwent carotid stent placement for rapid progression of the disease. No disease progression was seen on follow-up duplex examination in the remaining group, and no patient became symptomatic. Conclusions Fibromuscular dysplasia should be suspected in female patients with high-grade mid to distal carotid artery stenosis without significant atherosclerotic disease. This study demonstrates the usefulness of duplex ultrasound as both a screening test and diagnostic examination for carotid artery fibromuscular dysplasia. Follow-up is warranted in these patients.

Object Fusiform dilation of the supraclinoid internal carotid artery (FDCA) is a reported occurrence following surgery for suprasellar tumors, in particular craniopharyngiomas. We report our experience of the incidence and natural history of FDCA following aggressive surgical resection of craniopharyngiomas in children. Methods Between 1986 and 2006, 86 patients under the age of 21 underwent radical resection of craniopharyngiomas at our institution. Ten cases with < 1 year of follow-up imaging (6), perioperative death (3), or nonsuprasellar tumors (1) were excluded. Data were retrospectively collected on the remaining 76 patients (43 male, 33 female; mean age 9.5 years; mean tumor size 3.3 cm) to determine the risk factors for and the rate and clinical significance of FDCA. Results Fifty patients had primary tumors and 26 patients received treatment before referral to our center. Sixty-six children (87%) had gross-total resection. At a mean follow-up time of 9.9 years, FDCA had developed in 7 patients (9.2%), all of whom had primary tumors and gross-total resection. The mean time to onset of FDCA was 6.8 months (range 3–11 months) with stabilization occurring at mean of 17.7 months (range 9–29.5 months). The mean size of the aneurysms was 9.1 mm (range 7.1–12 mm). After arrest, no lesions showed continued growth on serial imaging or produced symptoms or required treatment. There were no significant differences in age, sex, tumor size, pre- or retrochiasmatic location, extent of resection, or surgical approach (p > 0.05) between patients with and without FDCA. Conclusions Fusiform dilation of the supraclinoid internal carotid artery occurred in almost 10% of children following radical resection of craniopharyngiomas. In agreement with other reports, the authors concluded that FDCA probably occurs as a result of surgical manipulation of the supraclinoid carotid artery and should be managed conservatively because very few patients exhibit continued symptoms or experience growth or rupture of the lesion.
