Introduction: Extracranial carotid artery aneurysms and pseudoaneurysms (ECCAs) are rare pathologies with various etiologies, presentations, and management strategies. Historically, open aneurysm resection and arterial repair have been the gold standard management of ECCAs. Our study examines the evolving experience with endovascular management of ECCAs. Methods: We performed a literature review of multiple studies on endovascular and open management of carotid artery aneurysms and pseudoaneurysms. Conclusions: Endovascular stenting is technically feasible and clinically effective for the treatment of carotid artery aneurysms and pseudoaneurysms. Further follow-up is required regarding long-term safety and efficacy.

Objective: Both true and false extracranial carotid artery aneurysms (ECAA) are a potential source of morbidity and mortality. While ECAA have historically been treated surgically, endovascular reconstruction with stenting is an emerging treatment option. The aim of our study was to report clinical/radiologic outcomes following endovascular repair of ECAAs. Methods: A comprehensive systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Results: A total of 68 case reports and case series, comprising 162 patients, were included. Most patients presented with at least one symptom or sign related to the ECAA (89.5%; N = 145/162). In 42.6% (N = 69/162) and 46.3% (N = 75/162) of the cases polytetrafluoroethylene covered and uncovered stents were deployed respectively. Immediate post-procedural imaging demonstrated complete aneurysm exclusion in 86.4% (N = 140/162) of the cases and minimal filling of the aneurysm sack in 10.5% (N = 17/162) of all cases. Perioperative adverse event rates were 3.1% for stroke, 1.2% for transient ischemic attack (TIA) and 4.3% for mortality. During a mean follow-up of 21.8months, there were additionally observed one stroke, two TIAs and three deaths. Overall 88.6 % of the patients (N = 117/132) remained asymptomatic, partially recovered or at least did not suffer from new neurologic deficits during follow up, with no signs of stenosis or occlusion of the carotid artery. Conclusions: Endovascular stenting for the treatment of ECAAs is feasible with acceptable short- and long-term clinical and radiologic outcomes. Prospective real-world studies are needed to further validate the safety and the long-term patency of endovascular repair.

Object. Carotid angioplasty with stent placement has been proposed as an alternative method for revascularization of carotid artery (CA) stenosis. A novel stent with a coiled sheet design (NexStent; EndoTex Interventional Systems, Inc., Cupertino, CA) has been introduced because it provides improved flexibility over conventional tubular designs during navigation through tortuous arterial segments. The authors report the results of a multicenter study in which they evaluated the safety, feasibility, and effectiveness of this stent in the treatment of CA stenosis. Methods. Enrollment was limited to patients with 70% or more symptomatic or asymptomatic stenosis of the internal CA. The primary end point was a technically successful implantation procedure (delivery of the stent to the target site and retrieval of the delivery device) resulting in less than 30% residual stenosis on angiograms obtained immediately postprocedure and no death or ipsilateral stroke immediately after or within 30 days following the procedure. The secondary effectiveness end point was prevention of an ipsilateral stroke within 31 days to 1 year postprocedure. The tertiary effectiveness end point was less than 70% residual stenosis demonstrated on CA Doppler ultrasonography performed at 6 and 12 months. Forty-four patients (mean age 71 years, range 51–89 years; 30 patients were men and 18 [41%] had symptomatic stenotic lesions) were treated using 45 NexStents (two stents were placed in one patient). Residual stenosis on postprocedure angiograms was less than 30% in all patients. The 1-month primary end point was achieved in 41 patients (93%). The three major adverse events that occurred within 30 days were one death related to congestive heart failure and two ipsilateral strokes, one of which resulted in death. No ipsilateral stroke occurred between 1 and 12 months postprocedure among 35 patients who completed the follow-up evaluation. Asymptomatic recurrent stenosis was identified in one patient at 6 months postprocedure, requiring the performance of repeated angioplasty. Conclusions. Placement of the NexStent was feasible and resulted in the effective treatment of patients with CA stenosis, with promising long-term results.

Abstract. Background: We present the methods and results of the surgical management of extracranial carotid artery aneurysms (ECCA). Postoperative complications including early and late neurological events were analysed. Correlation between reconstruction techniques and morphology of ECCA was assessed in this retrospective study. Patients and methods: In total, 32 reconstructions of ECCA were performed in 31 symptomatic patients with a mean age of 59.2 (range 33 - 84) years. The causes of ECCA were divided among atherosclerosis (n = 25; 78.1 %), previous carotid endarterectomy with Dacron patch (n = 4; 12.5 %), iatrogenic injury (n = 2; 6.3 %) and infection (n = 1; 3.1 %). In 23 cases, intervention consisted of carotid bypass. Aneurysmectomy with end-to-end suture was performed in 4 cases. Aneurysmal resection with patching was done in 2 cases and aneurysmorrhaphy without patching in another 2 cases. In 1 case, ligature of the internal carotid artery (ICA) was required. Results: Technical success defined as the preservation of ICA patency was achieved in 31 cases (96.9 %). There was one perioperative death due to major stroke (3.1 %). Two cases of minor stroke occurred in the 30-day observation period (6.3 %). Three patients had a transient hypoglossal nerve palsy that subsided spontaneously (9.4 %). At a mean long-term follow-up of 68 months, there were no major or minor ipsilateral strokes or surgery-related deaths reported. In all 30 surviving patients (96.9 %), long-term clinical outcomes were free from ipsilateral neurological symptoms. Conclusions: Open surgery is a relatively safe method in the therapy of ECCA. Surgical repair of ECCAs can be associated with an acceptable major stroke rate and moderate minor stroke rate. Complication-free long-term outcomes can be achieved in as many as 96.9 % of patients. Aneurysmectomy with end-to-end anastomosis or bypass surgery can be implemented during open repair of ECCA.

Fusiform dilatation of the internal carotid artery (FDCA) is a known postoperative imaging finding after craniopharyngioma resection. FDCA has also been reported following surgery for other lesions in the suprasellar region in pediatric patients and is thought to be due to trauma to the internal carotid artery (ICA) wall during tumor dissection. Here, the authors report 2 cases of pediatric patients with FDCA. Case 1 is a patient in whom FDCA was visualized on follow-up scans after total resection of a craniopharyngioma; this patient’s subsequent scans and neurological status remained stable throughout a 20-year follow-up period. In case 2, FDCA appeared after resection and fenestration of a giant arachnoid cyst in a 3-year-old child, with 6 years of stable subsequent follow-up, an imaging finding that to the authors’ knowledge has not previously been reported following surgery for arachnoid cyst fenestration. These cases demonstrate that surgery involving dissection adjacent to the carotid artery wall in pediatric patients may lead to the development of FDCA. On very long-term follow-up, this imaging finding rarely changes and virtually all patients remain asymptomatic. Neurointerventional treatment of FDCA in the absence of symptoms or significant late enlargement of the arterial ectasia does not appear to be indicated.

BackgroundCoronary artery aneurysms (CAAs) are increasingly diagnosed on coronary angiography; however, controversies persist regarding their optimal management. In the present study, we analysed the long-term outcomes of patients with CAAs following three different management strategies.MethodsWe performed a retrospective review of patient records with documented CAA diagnosis between 2000 and 2005. Patients were divided into three groups: medical management versus percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG). We analysed the rate of major cardiovascular and cerebrovascular events (MACCEs) over a period of 10 years.ResultsWe identified 458 patients with CAAs (mean age 78±10.5 years, 74.5% men) who received medical therapy (N=230) or underwent PCI (N=52) or CABG (N=176). The incidence of CAAs was 0.7% of the total catheterisation reports. The left anterior descending was the most common coronary artery involved (38%). The median follow-up time was 62 months. The total number of MACCE during follow-up was 155 (33.8%); 91 (39.6%) in the medical management group vs 46 (26.1%) in the CABG group vs 18 (34.6%) in the PCI group (p=0.02). Kaplan-Meier survival analysis showed that CABG was associated with better MACCE-free survival (p log-rank=0.03) than medical management. These results were confirmed on univariate Cox regression, but not multivariate regression (OR 0.773 (0.526 to 1.136); p=0.19). Both Kaplan-Meier survival and regression analyses showed that dual antiplatelet therapy (DAPT) and anticoagulation were not associated with significant improvement in MACCE rates.ConclusionOur analysis showed similar long-term MACCE risks in patients with CAA undergoing medical, percutaneous and surgical management. Further, DAPT and anticoagulation were not associated with significant benefits in terms of MACCE rates. These results should be interpreted with caution considering the small size and potential for selection bias and should be confirmed in large, randomised trials.

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.
