A 65-year-old woman with severe mitral stenosis was admitted to our hospital. She had been previously diagnosed with systemic lupus erythematosus (SLE) and had been taking prednisolone (5 mg/day) for 19 years. As SLE patients with prolonged steroid use are known to be at risk of an aortic dissection and aneurysm, femoral artery was chosen for arterial perfusion to reduce the risk of a dissection of the ascending aorta. However, hemostasis was difficult at the insertion point of the catheter to infuse the antegrade cardioplegic solution...

Granulomatosis with polyangiitis (GPA) is the name that has been used in recent years for Wegener's granulomatosis. This condition is a systemic inflammatory disease characterised by necrotizing vasculitis that affects small and medium-sized blood vessels (capillaries, arterioles, venules and arteries). The granulomatous inflammation affects the respiratory system; it also commonly affects the kidney and can very rarely affect large vessels such as the aorta and the surrounding retroperitoneal tissue. Early diagnosis and treatment is of vital importance because of the high risk of dissection and of obstruction of retroperitoneal structures...

BACKGROUND: Arterial vessel wall dissection is a rare, life-threatening and rarely described complication in childhood Takayasu Arteritis (cTA). Prevalence and risk factors for arterial dissection in cTA are unknown. We sought to study the prevalence and analyse risk factors for arterial dissection in cTA. FINDINGS: A single center retrospective review of all children with cTA was performed. Patients with arterial dissection at cTA diagnosis were reported in detail and compared to the remaining single center retrospective cohort of children without dissection...

With 16.9 million people who suffered a first-ever stroke in 2010 worldwide, stroke is a very common vascular disease. Epidemiologic studies have played an essential role in assessing this burden and in detecting the risk factors for stroke. Primary prevention of these risk factors, primarily hypertension, smoking, diabetes, and atrial fibrillation, has reduced the incidence in high-income countries. However, stroke remains a major cause of death and disability, and therefore research should be continued. Subarachnoid hemorrhages are less prevalent than strokes but have an even higher risk of death...

INTRODUCTION: To our knowledge the most recent article on celiac dissection was published in 2015 and reported 24 known cases of spontaneous isolated celiac trunk dissection [2]. While some of those cases reported hypertension as a risk factor, no other case presents as hypertensive emergency with an isolated celiac artery dissection. PRESENTATION OF CASE: A 43 year-old man with a past medical history of uncontrolled hypertension, for which he had reportedly been non-compliant with follow-up, presented with complaints of severe, sudden-onset epigastric pain which was non-radiating and constant for 1 hour prior to arrival...

BACKGROUND AND PURPOSE: Middle cerebral artery steno-occlusive disease (MCAD) is not an uncommon cause of ischemic stroke in young Asians. Aside from atherosclerosis, the pathogenesis of MCAD include various nonatherosclerotic vasculopathies, most of which are yet to be defined. This study investigated the pathogenesis of symptomatic isolated MCAD in young Asian patients using high-resolution magnetic resonance imaging (HR-MRI) and mutation analysis of RNF213. METHODS: Patients aged <60 years with stroke or transient ischemic attack caused by MCAD were prospectively enrolled...

We report the case of a patient who had developed multiple cranial nerve palsies in the course of possible paraneoplastic neurological syndrome (PNS) associated with gallbladder cancer. Twelve days prior to visiting our hospital, a 69-year-old man began experiencing neurological symptoms, beginning with diplopia and progressing to ptosis of the left palpebra and subsequent complete closure of the eye within 8 days. Results of the initial medical examination indicated paresis of left oculomotor (III) and abducens (VI) nerves...

OBJECTIVES: IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition that can affect multiple organs and lead to tumefactive, tissue-destructive lesions. Reports have described inflammatory aortitis and periaortitis, the latter in the setting of retroperitoneal fibrosis (RPF), but have not distinguished adequately between these 2 manifestations. The frequency, radiologic features, and response of vascular complications to B cell depletion remain poorly defined...

Kawasaki disease is a self-limiting vasculitis presenting in childhood that can lead to aneurysms of the coronary arteries. Patients who develop giant coronary aneurysms have a high incidence of coronary stenoses and occlusions resulting in myocardial ischemia. The mainstay of treatment for these lesions is surgical bypass due to complex coronary anatomy and a high rate of chronic total occlusions precluding traditional percutaneous coronary intervention techniques. We report the first successful percutaneous revascularization of two chronically occluded giant coronary aneurysms using the Hybrid Interventional Strategy for approaching chronic total occlusions...

Previous studies reported a 2- to 17-fold higher risk of aortic complications (dilation or dissection) in patients with giant-cell arteritis (GCA). We aimed to determine whether or not GCA patients with large-vessel involvement demonstrated by positron emission tomography with F-fluorodeoxyglucose combined with computed tomography (FDG-PET/CT) have a higher risk of aortic complications. We conducted a retrospective multicenter study between 1995 and 2014. Patients were included if they fulfilled at least 3 American College of Rheumatology criteria for GCA, or 2 criteria associated with extratemporal biopsy-proven giant-cell vasculitis; they underwent at least 1 FDG-PET/CT scan at diagnosis or during follow-up; and the morphology of the aorta was assessed by medical imaging at diagnosis...

OBJECTIVE: To review the principal findings on computed tomography angiography for segmental arterial mediolysis, and to emphasize the points that help to differentiate it from other vasculopathies such as vasculitis. We also review the protocols for follow-up and the various treatment options. CONCLUSION: Segmental arterial mediolysis is a rare disease that is defined as a non-atherosclerotic, non-hereditary, and non-inflammatory vasculopathy characterized by lysis of the medial layer of the arterial wall...

Myocardial infarction in the absence of coronary artery disease is a rare finding. Mechanisms leading to infarction include paradoxical embolism, coronary dissection, coronary spasm, hypercoagulable states, vasculitis, or-in presence of a coronary fistula-a steal phenomenon. We report for the first time a case of a patient with an arteriovenous coronary fistula and no coronary artery disease, suffering from three incidents of myocardial infarction in three different coronary regions-of which only one was located in the area supplied by the coronary artery connected to the fistula...

Acquired coronary diseases include aneurysms, fistulae, dissections, and stenosis. Aneurysms may occur secondarily to Kawasaki disease, a childhood vasculitis, the prognosis of which depends on the coronary involvement, or they may be degenerative, infectious, inflammatory, or traumatic in origin. Fistulae develop between the coronary arterial system and a pulmonary or bronchial artery, or cardiac cavity. Dissections may occur spontaneously or may be post-traumatic. These coronary abnormalities may be found incidentally or may present as complications, infarction or rupture...

BACKGROUND: Central nervous system vasculitis has multiple presentations, including stroke, seizures, cranial nerve palsies, and encephalopathy. CASE DESCRIPTION: We present the case of an unresponsive 45-year-old woman with vasculitis associated with fulminant intracranial vessel dissection and occlusion with ischemic strokes and subarachnoid hemorrhage secondary to aneurysm rupture. Imaging studies demonstrated both ischemic and hemorrhagic strokes. She had a ruptured right internal carotid artery dorsal variant aneurysm, right vertebral artery dissection with occlusion and posterior inferior cerebellar artery infarct, left vertebral artery dissection, and severe vasculitis involving intracranial and extracranial vessels...

OBJECTIVES: Takayasu arteritis is a relatively rare chronic nonspecific form of large-vessel vasculitis in which the involved vessels develop stenoses, occlusions, dilatations or aneurysms, and dissections. Dissections of the arteries in patients with Takayasu arteritis are not well understood. In this study, we explored the sonographic characterization of these rare complications secondary to Takayasu arteritis. METHODS: We evaluated arterial dissections in 72 patients with a clinical diagnosis of Takayasu arteritis by vascular sonography and transthoracic echocardiography...

BACKGROUND: High-resolution magnetic resonance vessel wall imaging (HRMR-VWI) has been used to explore vascular diseases such as vasculitis and vulnerable plaque of intracranial arteries. Although vessel wall inflammation is suspected as one of the causes of cerebral arterial dissection, there have been few reports regarding the application of HRMR-VWI to arterial dissection. We have therefore evaluated the efficacy of HRMR-VWI in patients with vertebrobasilar artery dissection. METHODS: HRMR-VWI was performed on 5 patients who had been diagnosed with nonhemorrhagic vertebrobasilar artery dissection...

Inflammatory aortic diseases may occur with and without dilatation and are complicated by obstruction, rupture and dissection. Infections originate from periaortic foci or septicaemia and tend to result in the rapid development of aneurysms. Large vessel vasculitis due to Takayasu arteritis in younger and giant cell arteritis (GCA) in older patients is located in all layers of the aortic wall and prevails in the thoracic section. GCA patients are prone to developing aortic complications in the late course of disease...

There has been no previous systematic study of bullous skin diseases with granular basement membrane zone deposition exclusively of C3. In this study we collected 20 such patients, none of whom showed cutaneous vasculitis histopathologically. Oral dapsone and topical steroids were effective. Various serological tests detected no autoantibodies or autoantigens. Direct immunofluorescence for various complement components revealed deposition only of C3 and C5-C9, indicating that no known complement pathways were involved...
