Fibromuscular dysplasia carotid

We present a case of a 41-year-old female presenting with recurrence of ischemic stroke on subtherapeutic doses of dabigatran. She had a history of embolic stroke of undetermined sources at the age of 40, and underwent implantable cardiac monitor implantation and had started dabigatran. One year after the first ischemic stroke, she presented with sudden dysarthria and left hemiparesis and was admitted to our hospital. An MRI of the head revealed acute cerebral infarction in the right corona radiata, and an MR angiography revealed right M2 occlusion...

One of the uncommon stroke presentations is the isolated wrist drop syndrome, caused by a stroke affecting the hand knob area, with the embolic mechanism being the most commonly identified mechanism. Here, we present the case of a 62-year-old female patient who presented with acute-onset isolated wrist drop secondary to right internal carotid artery fibromuscular dysplasia with a string of beads appearance and coexisting proximal atherosclerotic severe stenosis. The patient underwent successful carotid artery stenting...

Fibromuscular dysplasia (FMD) is an idiopathic and systemic non-inflammatory and non-atherosclerotic arterial disease. Fifteen to 25 % of patients with FMD present with arterial dissection in at least one arterial bed. Conversely, a substantial number of patients with renal, carotid and visceral dissection have underlying FMD. Also, while few patients with FMD develop coronary artery dissection, lesions suggestive of multifocal FMD have been reported in 30 to 80% of patients with Spontaneous Coronary Artery Dissection (SCAD), and the relation between these two entities remains controversial...

Neurofibromatosis Type 1 (NF1) is a rare cause of ischemic stroke (IS) in the general population. We report a case of a young patient with NF1 in whom IS was caused by fibromuscular dysplasia. An angiographic study demonstrated occlusion in the right internal carotid artery (ICA), just after its origin, and the left ICA, just before the intracranial portion, and brain magnetic resonance imaging showed the limits of an area of brain infarction in the right frontoparietal region. Despite these concomitant neuroimaging findings, this association is rare, and it is difficult to establish the contribution to the outcome made by each of these diseases, which treatment is the best to implement, or what prognosis is...

INTRODUCTION: Described for 60 years under various names, the carotid web is a suspected cause of cryptogenic stroke, especially in young patients. The web creates an intraluminal protrusion that may contribute to turbulent flow and thrombus embolization into cerebral arteries. Although the carotid web has frequently been related to arterial fibrodysplasia, its natural history and pathological description remain unclear. PATIENTS: Among all consecutive patients admitted to the stroke unit of Sainte-Anne hospital and referred to the vascular surgery department from January 2015 to December 2022, we retrospectively identified 9 patients with a carotid web...

Atypical fibromuscular dysplasia of the bulb or carotid web is a nonatheromatous pathology more common in African and African-American populations. It is implicated in the occurrence of cerebral infarcts of unknown causes. Its diagnosis is made by angio-CT of the supra-aortic trunks and is characterized by a defect in the posterior wall of the bulb. Treatment with antiplatelet agents prevents the occurrence of stroke, but radical treatment remains surgical and endovascular. We report 2 observations of carotid web diagnosed and medically managed at the regional hospital of Saint Louis...

Carotid web (CW) is considered a variant of intimal fibromuscular dysplasia. CW represents between 9.4% and 37% of ischemic strokes that were initially misclassified as "cryptogenic." However, in Latin America, there is a lack of detection. We present 5 cases of ischemic stroke due to CW and discuss the usefulness of multiplanar reformatting (MPR) imaging in computed tomography angiography. The identification of CW with the use of tridimensional (3D) reconstructions and maximum intensity projection was 20%, the rest was misdiagnosed as atherosclerotic plaque...

Since ancient times, physicians have been aware of correlations between the carotid artery and consciousness; however, carotid stenosis was only recently identified as the cause of atherothrombotic ischemic stroke. In 1658, Wepfer described the first suggestion of a link between symptoms of cerebral arterial insufficiency and carotid pathology. In 1951, Fisher reported details of the symptoms and pathological findings and emphasized that cervical atheromatous lesions induced cerebral infarction with various symptoms...

Carotid artery web (CaW) is a rare focal fibromuscular dysplasia, which is an underappreciated risk factor for transient ischemic attack. This case illustrates the dynamic evolution of secondary thrombus and plaque in CaW, and the importance of carotid doppler ultrasound in early detection and follow-up.

Cerebral cavernous malformations (CCMs) are the second most common type of cerebral vascular lesions. They are often associated with other vascular lesions, typically developmental venous anomalies. CCMs are not known to be associated with cerebral aneurysms and there is a paucity of literature on this occurrence. We report the case of a patient who presented with a focal seizure from a symptomatic CCM with acute hemorrhage and was incidentally found to have a cerebral aneurysm and bilateral internal carotid artery (ICA) dissections secondary to fibromuscular dysplasia...

BACKGROUND: Carotid artery stenting (CAS) is considered an important tool in carotid revascularization. Carotid artery stenting is usually performed by using self-expandable stent with different designs. The stent design influences many physical characteristics. Also, it may affect the complication rate with special relevance to perioperative stroke, hemodynamic instability, and late restenosis. METHODS: This study comprised all consecutive patients who underwent carotid artery stenting for atherosclerotic carotid stenosis from March 2014 to May 2021...

BACKGROUND: Fibromuscular dysplasia (FMD) has a high prevalence of associated nontraumatic carotid artery dissection, which could further result in transient ischaemic attack (TIA) or stroke. Limb shaking TIA is an unusual form of TIA that is commonly discribed in elderly patients with atherosclerotic backgrounds, while there are limited data about it in patients with FMD. Furthermore, discussions of limb shaking TIA in nonelderly patients are scarce. CASE PRESENTATION: An Asian 47-year-old female presented with intermittent involuntary movement of the left upper limb accompanied by neck torsion...

OBJECTIVES: The aim of this study was to investigate the clinical characteristics of renal artery fibromuscular dysplasia (FMD) in patients in China and identify the cure rate of hypertension after angioplasty. METHODS: Consecutive hypertensive patients with renal artery stenosis caused by FMD who underwent catheter-based angiography, and were followed at two Chinese referral centres, were retrospectively analysed. All patients underwent a detailed investigation, including demographic characteristics, clinical characteristics, biochemical sampling, Doppler ultrasonography of carotid arteries, magnetic resonance angiography (MRA) of the intracranial artery, and CTA or MRA of the abdominal artery and catheter-based renal angiography...

BACKGROUND: Fibromuscular dysplasia (FMD) is a rare vasculopathy for which limited data are available particularly from Europe. Our aim was to study the clinical characteristics of a regional cohort of carotid fibromuscular dysplasia patients to assess their clinical outcomes and the rate of vascular complications. METHODS: A retrospective cohort study of all cases of carotid/cerebrovascular FMD presenting to our regional vascular service (catchment population approximately 2 million), between 1998 and 2020...

UNLABELLED: Fibromuscular dysplasia (FMD) is non-atherosclerotic, non-inflammatory vascular disease that results in arterial stenosis. The lesions in FMD are commonly found in the renal and extracranial carotid and vertebral arteries, but the prevalence of FMD with lesions in the coronary artery is unclear. Although the vascular morphology of coronary artery lesion in FMD is mostly dissection, the following case of FMD showed the stenotic and aneurysmal lesions in coronary arteries, which was treated by percutaneous coronary angioplasty...

Fibromuscular dysplasia (FMD) can manifest outside of its classic presentation with unusual pathology. In the present report, we have described a case of an older male patient with aortic degeneration related to acute type B dissection who had required emergent left carotid-subclavian transposition and aortic stenting. Intraoperatively, his axillary artery FMD led to acute upper extremity ischemia. The patient was treated with classic maneuvers, including balloon angioplasty, reflecting the best practices in vascular surgery...

BACKGROUND: Fibromuscular dysplasia (FMD) is a noninflammatory and nonatherosclerotic arteriopathy that is characterized by irregular cellular proliferation and deformed construction of the arterial wall that causes segmentation, constriction, or aneurysm in the intermediate-sized arteries. The incidence of FMD is 0.42-3.4%, and the unilateral occurrence is even rarer. Herein, we report a rare case of a localized extracranial carotid unilateral FMD associated with recurrent transient ischemic attacks (TIAs) treated by extracranial-intracranial bypass for indirect revascularization...

OBJECTIVE: Fibromuscular dysplasia (FMD) is a noninflammatory arterial disease that affects extracranial carotid arteries in young patients. The ideal treatment of FMD is still debatable and the role of carotid artery stenting (CAS) is controversial. The aim of this study was to assess the feasibility and outcomes of CAS in patients with FMD. METHODS: Retrospective analysis of patients who underwent CAS was performed utilizing the Vascular Quality Initiative (VQI) database from December 2012 to May 2021...

Cervical Artery Dissection (CeAD) is a frequent stroke etiology for patients younger than 50 years old. The most common immediate complications related to CeAD are headache and neck pain (65-95%), TIA/ischemic stroke (>50%), and partial Horner's syndrome (25%). The prevailing hypothesis regarding the pathogenesis of sCeAD is that the underlying constitutional vessel wall weakness of patients with sCeAD is genetically determined and that environmental factors could act as triggers. The stroke prevention treatment of CeAD remains controversial, involving anticoagulation or antiplatelet therapy and potentially emergent stenting and/or thrombectomy or angioplasty for selected cases of carotid artery dissection with occlusion...
