Background and Purpose: Fibromuscular dysplasia (FMD) is a non-atherosclerotic arteriopathy most often affecting the carotid and renal arteries. In the United States Registry for FMD, 41.7% of patients experienced an aneurysm and/or dissection by the time of entry into the Registry. We sought to determine the occurrence of neurovascular events after FMD diagnosis and any changes on cervical artery imaging that may be attributable to FMD. Methods: Patients followed at the Mount Sinai Medical Center (US Registry for FMD enrollment center) with confirmed FMD and > 1 cervical artery imaging study (at least ± 6 months from the baseline carotid duplex ultrasound [CDU]) between the years 2003 and 2015 were included. Medical records and cervical artery imaging ([CDU], magnetic resonance angiogram [MRA], and computed tomography angiogram [CTA]) were reviewed. New arterial dissection, aneurysm, transient ischemic attack, stroke, or new FMD findings were recorded. Results: Among 146 FMD patients with complete information, 52 (35.6%) had an aneurysm and 52 (35.6%) had a dissection. Mean clinical follow-up was 35.3 ± 25.3 months (range 5–153 months); patients underwent 4 ± 2.7 CDU (range 1–17); 86.3% had ≥1 neck MRA or CTA. After FMD diagnosis, 3 patients (2%) experienced a new carotid artery dissection; 1 patient experienced a stroke due to concomitant atherosclerosis. No new aneurysms occurred. In patients with cervical artery FMD, imaging findings remained stable throughout follow-up. No patient developed new cervical artery FMD findings on follow-up imaging. Conclusions: No new cervical artery FMD or aneurysm was observed on subsequent imaging. New carotid dissection was uncommon over a mean follow-up period of 35.3 ± 25.3 months and was the only non-atherosclerotic vascular event observed after FMD diagnosis.

Nearly 800,000 strokes are reported in the United States annually, with an economic impact upward of $33 billion. Carotid artery disease, familiar to all vascular surgeons, accounts for just over one fifth of these strokes. However, these cases reflect an opportunity for the surgeon to intervene and mitigate the substantial burden of stroke. This review includes the epidemiology of stroke in the United States and the carotid artery and noncarotid etiologies of stroke, including atherosclerotic disease, fibromuscular dysplasia, carotid artery dissection, and cardioembolism. The clinical presentations of ischemic and hemorrhagic stroke and transient ischemia attacks are examined, as are the major findings expected in the patient history and physical examination. Strategies for further evaluation of the patient are discussed, including the use of sonographic imaging of the carotid artery and the relative advantages and disadvantages among the dominant modes of brain imaging. New updates to the review include interventional approaches toward the treatment of acute ischemic stroke, as well as the latest strategies regarding the timing of carotid endarterectomy after stroke and the utility of carotid artery stenting in these patients, with active areas of current research highlighted. Figures show a computed tomographic (CT) angiogram of fibromuscular dysplasia of an internal carotid artery, a CT angiogram of an internal carotid artery dissection showing a defect in the dissection, a CT scan demonstrating hemorrhagic conversion of cardioembolic stroke, a CT scan of acute thalamic hemorrhage, a CT scan of evolving ischemic stroke, a T2-weighted image demonstrating acute left frontal stroke and remote right frontal stroke, T1- and T2-weighted images of right parietal ischemic stroke, and M1 occlusion of a middle cerebral artery treated successfully with transcatheter thrombectomy.

Purpose: To study the clinical usefulness of serial color-coded duplex ultrasound (DUS) examinations in cervical artery dissection (CeAD) patients. Methods: Single-center, CeAD registry-based re-review of serial, routine DUS exams in consecutive CeAD patients treated at the Stroke Center Basel, Switzerland (2009–2015). Two experienced raters reassessed all DUS for the occurrence of new arterial findings during follow-up, that is. (i) recanalization of the dissected artery (if occluded at baseline), (ii) delayed occlusion of a patent dissected artery, and (iii) recurrent CeAD. We studied whether these new arterial findings were associated with clinical symptoms. Results: In 94 CeAD patients (n = 40 female [42.6%], median age 46 years [interquartile range (IQR) 36.2–53]), 506 DUS examinations were reviewed covering a median length of follow-up of 54.1 weeks (IQR 30.5–100.5). In total, 105 dissected arteries were detected, of which 27 (25.7%) were occluded. In 28/94 patients (29.8%), 31 new arterial findings were recorded, which were associated with clinical symptoms in 9/31 (30%) patients. Recanalization of occluded CeAD was observed in 22/27 (81.5%) arteries and occurred in 20/22 arteries within 3 months. In 4/22 patients (18.2%), recanalization was associated with clinical symptoms (ischemic events [n = 2], pure local symptoms [n = 2]). Delayed occlusions were observed in 4/78 (5.1%) dissected arteries patent at baseline. All were clinically asymptomatic and occurred within 14 days from baseline. Recurrent CeAD (all symptomatic) occurred in 5 previously non-dissected arteries. Conclusion: In CeAD patients, follow-up DUS identified new arterial findings, of which several were associated with clinical symptoms: we found that about 1 of 5 recanalizations were associated with clinical symptoms, of whom half were ischemic symptoms. Further, delayed occlusions occurred in patients with no or mild stenosis at baseline and were asymptomatic. This study emphasizes the potential importance of repeated DUS in CeAD particularly in the early phase of up to 4 weeks.

Abstract Isolated dissection of the internal carotid artery (ICA) is rare in young patients and is a cause for strong suspicion of fibromuscular dysplasia (FMD), especially when associated with artery elongation and tortuosity. The natural history of cerebrovascular FMD is unknown and management of symptomatic patients can be challenging. We report the case of a 44-year-old female patient with a history of transient ischemic attack in the absence of cardiovascular risk factors, associated with an isolated left ICA dissection and kinking. Carotid duplex ultrasound confirmed the diagnosis of dissection and demonstrated severe stenosis of the left ICA. The patient underwent surgical repair and histopathological evaluation confirmed the diagnosis of FMD with dissection. An autogenous great saphenous vein bypass was performed and the patient had an uneventful recovery. Cervical carotid artery dissection can be related to underlying arterial pathologies such as FMD, and the presence of ICA tortuosity highlights certain peculiarities for optimal management, which might be surgical.

Background: Cervical artery dissection (CeAD) is one of the most frequent manifestations of fibromuscular dysplasia (FMD). However, the risk factors for CeAD are unknown. We investigated factors associated with CeAD in the ARCADIA (Assessment of Renal and Cervical Artery Dysplasia) registry and performed a pooled analysis of published and unpublished data. Methods: Patients included were women and men ≥18 years, diagnosed with renal, cervical, or intracranial artery FMD, prospectively recruited at 16 university hospitals in France and Belgium. Diagnosis of CeAD was established by stroke specialists in each participating center, according to standard diagnostic criteria. Associations between CeAD and potential determinants were assessed by calculations of crude and adjusted odds ratios. Results: Among 469 patients (415 women) with FMD, 68 (14.5%) had CeAD. CeAD patients were younger, more likely to be men and to have a history of migraine, and less likely to have a history of hypertension, than non-CeAD patients. In the multivariate analysis, male sex (OR=2.75 ; CI95% 1.39-5.46), history of migraine (OR=1.93 ; 1.08-3.44), age >50 years (OR=0.41 ; 0.23-0.74), history of hypertension (OR=0.35 ; 0.19-0.63), and the number of vascular beds involved by FMD >=3 (OR=2.46 ; 1.13-5.35) remained significantly associated with CeAD. We collected data from 2 published studies and unpublished data from the US and the European Registries. There was no overlap between studies. In a pooled analysis (289 CeAD in 1933 patients), male sex was significantly associated with CeAD (pooled OR=2.04 ; 1.41-2.95, I2=0%, Figure). Conclusion: In patients with FMD, male sex and multisite involvement are associated with of CeAD, in addition to other previous known risk factors.

Background and Purpose: Antiplatelet agents and anticoagulants are both accepted and commonly used agents for treatment of cervical artery dissection (CAD), though randomized clinical trials are lacking. We report on the use of novel oral anticoagulants for CAD and compared their efficacy and safety to traditional anticoagulants. Methods: We retrospectively identified patients diagnosed with CAD at a single academic center between July 2010 and December 2012. Patients treated with novel anticoagulants (NOAC: dabigatran or rivaroxaban), other anticoagulants (AC: warfarin, heparin, or low molecular weight heparin), or antiplatelet agents (AP: aspirin, clopidogrel, or aspirin-dypyridamole) were compared for baseline characteristics, recurrent stroke, vessel recanalization on follow-up, and bleeding complications using Fisher’s exact and student t-tests. Results: During the study period, 110 patients with CAD were included, of whom 20 (18%), 61 (55%), and 29 (26%) were treated initially with a NOAC, AC, and AP, respectively. Clinical follow-up was available in 98 (89.1%) patients while radiographic follow-up was available in 88 (80%) patients. NOAC-treated patients were more likely to have presented with ischemic stroke symptoms (90% vs. 55.7%, p=0.007) but had similar rates of severe stenosis (60% vs. 53.3%, p=0.522) and intraluminal/intramural thrombus (70% vs. 57.6%, p=0.327) on initial vascular imaging compared to AC patients. There was 1 recurrent stroke in the NOAC group and 1 in the AC group. Similar proportions of patients had resolved or improved stenosis on follow-up imaging (NOAC: 66.7 vs. AC: 63.3%, p=0.217). Hemorrhagic complications were more likely to occur in AC compared to NOAC patients (17.0% vs. 0%, p=0.019). Conclusion: In this retrospective study, use of novel oral anticoagulants for CAD was associated with similar rates of recurrent stroke and vessel recanalization on follow-up imaging but with fewer hemorrhagic complications. Given their safety profile, NOACs may be a reasonable alternative to traditional anticoagulants in CAD. Prospective validation of these findings is needed.

The health issue addressed is the unmet need to universally screen and treat depression, which is one of the most common mental health disorders among adults in the United States. The US Preventive Services Task Force recommends screening adults for depression in primary care and using evidence-based protocols. This quality improvement project implemented VitalSign6, a measurement-based care program, to improve depression screening and treatment of adults in primary care at an academic medical center. A pre-post design was used to determine effectiveness of changes in screening, outcomes, and satisfaction. Of 1200 unique adult patients, 95.4% received initial screening. Providers diagnosed and administered measurement-based care to 236 patients. After 14 weeks, 27.5% returned for at least 1 follow-up. Results showed a statistically significant decrease in self-reported depression scores from baseline to follow-up. VitalSign6 was effective in improving identification and management of depression in primary care.
