Polyarteritis nodosa (PAN) is a necrotising vasculitis that involves medium and small vessels. PAN generally presents with constitutional, cutaneous, neurological, renal and gastrointestinal manifestations. However, PAN initially involving a single organ/system is uncommon. Here, we present a 42-year-old man who was hospitalised because of severe right upper quadrant abdominal pain that started 2 months before. Physical examination was remarkable for right upper quadrant abdominal tenderness. Abdominopelvic CT showed lymphadenopathy but no hepatic, gallbladder, pancreatic, intestinal or renal abnormalities...

Metal-induced encephalopathy after stent-assisted coil embolization is extremely rare. The present report describes two patients who presented with symptomatic intracranial parenchymal edematous lesions after stent-assisted coil embolization. A 64-year-old woman underwent stent-assisted coil embolization for a left internal carotid artery aneurysm; 21 days after the procedure she presented with right hand weakness and MRI revealed multifocal white matter lesions. Another woman aged 52 years underwent stent-assisted coil embolization for right vertebral artery aneurysm; 18 days after the procedure she presented with left-sided sensory disturbance and MRI demonstrated multiple white matter lesions...

BACKGROUND: Interventions for aortic aneurysm sac growth have been reported across multiple time points after endovascular aortic aneurysm repair (EVAR). We report the long-term outcomes of patients after EVAR monitored with duplex ultrasound (DUS) imaging with respect to the need for and type of intervention after 5 years. METHODS: We report a series of patients who were monitored with DUS imaging for a minimum of 5 years after EVAR. DUS imaging was performed in an accredited noninvasive vascular laboratory, and computed tomography angiography was only performed for abnormal DUS findings...

Pathophysiological processes following subarachnoid hemorrhage (SAH) present survivors of the initial bleeding with a high risk of morbidity and mortality during the course of the disease. As angiographic vasospasm is strongly associated with delayed cerebral ischemia (DCI) and clinical outcome, clinical trials in the last few decades focused on prevention of these angiographic spasms. Despite all efforts, no new pharmacological agents have shown to improve patient outcome. As such, it has become clear that our understanding of the pathophysiology of SAH is incomplete and we need to reevaluate our concepts on the complex pathophysiological process following SAH...

Heterozygous mutations in the SMAD3 gene were recently described as the cause of a form of non-syndromic familial aortic thoracic aneurysm and dissection (FTAAD) transmitted as an autosomal dominant disorder and often associated with early-onset osteoarthritis. This new clinical entity, called aneurysms-osteoarthritis syndrome (AOS) or Loeys-Dietz syndrome 3 (LDS3), is characterized by aggressive arterial damages such as aneurysms, dissections and tortuosity throughout the arterial tree. We report, here, the case of a 45 year-old man presenting multiple visceral arteries and abdominal aortic aneurysms but without dissection of the thoracic aorta and without any sign of osteoarthritis...

Background A major challenge in the management of patients with unruptured intracranial aneurysms (UIAs) is to identify criteria indicating a higher risk of future UIA rupture. We report a rare patient with documented short-term bleb growth of an UIA followed by a fatal aneurysm rupture supporting the high risk of rupture of short-term shape changes in UIAs. Case Description A 72-year-old man with an incidental unruptured anterior communicating artery aneurysm of 9 mm showed a bleb growth on the aneurysm sac at 6-week follow-up computed tomography angiography (CTA)...

Neurofibromatosis type I (NFI), also called Von Recklinghausen disease, is an autosomal dominant disease secondary to a genetic mutation on the long arm of chromosome 17. This disorder affects neural crest cells. Cutaneous clinical forms are the most frequent with multiple benign skin neurofibromas, associated with café au lait skin spots and iris hamartomas. Vascular abnormalities in NF1 are rare but have also been well described. The most frequent abnormalities are characterized by arterial aneurysm degeneration, stenosis, and malformations...

BACKGROUND: Kawasaki disease (KD) is classified as a systemic vasculitis syndrome and QT interval dispersion (QTD) has been associated with cardiac involvement and disease activity in patients with cardiovasculitis. We examined whether baseline QTD could predict a response to intravenous immunoglobulin (IVIG) in KD.Methods and Results:QTD was recorded in 86 patients with KD before IVIG, who were separated into IVIG responders (R group; n=62) and nonresponders (N group; n=24). The association between baseline QTD and response to IVIG was investigated, and the predictive response value was compared with conventional risk scores from Gunma and Kurume universities...

OBJECTIVE: Secondary brain injury leads to high morbidity and mortality rates in patients with aneurysmal subarachnoid hemorrhage (aSAH). However, evidence-based treatment strategies are sparse. Since heparin has various effects on neuroinflammation, microthromboembolism and vasomotor function, our objective was to determine whether heparin can be used as a multitarget prophylactic agent to ameliorate morbidity in SAH. METHODS: Between June 1999 and December 2014, 718 patients received endovascular treatment after rupture of an intracranial aneurysm at our institution; 197 of them were treated with continuous unfractionated heparin in therapeutic dosages after the endovascular procedure...

BACKGROUND: Genetic disorders affecting the arterial tree in the form of aneurysms and dissections are highly morbid conditions that strike younger persons leading to bleeding, infarction, or even death. Although clinically recognizable syndromes, notably Marfan, Ehlers Danlos, and Loeys--Dietz syndromes encompass the principal diagnosable phenotypes along the genetic vascular disorder spectrum, a substantial subset of patients cannot be adequately classified under a known diagnosis through clinical or molecular diagnostic methods...
