Background: Fibromuscular dysplasia affects generally renal artery, causing renovascular hypertension. The most classical angiographic pattern, string-of-beads, can be found in cervical and more ...rarely in other arteries. With the advance of endovascular procedures techniques, the number of open surgeries is decreasing, and complications related to the selective catheterization of diseased vessels are increasing.
Case Report: A 37-year-old man presenting with subarachnoid hemorrhage was submitted to angioplasty for dissecting aneurysms of vertebral artery with a good outcome. Several arteries were angiographically diagnosed with the dysplasia (renal, carotid, femoral), and some complications like stenosis, dissection, arteriovenous fistula, and dissecting aneurysm occurred in sequence.
Conclusions: FMD of cervical arteries is usually asymptomatic. There are no guidelines or protocols to cervical FMD treatment, being indicated only for the complications. Because of the vessels fragility, a several spontaneous or post endovascular procedure complications can be disastrous.
The life and death of Henrique Dumont (1832-1892) is little known, being usually remembered as Alberto Santos-Dumont's father. This report describes the history of this Brazilian engineer, also known ...as the King of Coffee, who achieved enormous business success and fortune in the late nineteenth century. In 1890, during the inspection of his farm, the world's largest coffee plantation at that time, he fell from a carriage, which left him a hemiplegic. This forced him to sell the farm and move to France for treatment. Before his death two years later, he gave his 18-year-old son bits of advice, and distributed his inheritance, which allowed Alberto to study in Paris and finance his experiments that would culminate in the development of the airplane. The diagnostic and therapeutic possibilities are also discussed.

Moyamoya disease is a chronic occlusive cerebrovascular disease that is non-inflammatory and non-atherosclerotic. It is characterized by endothelial hyperplasia and fibrosis of the intracranial ...portion of the carotid artery and its proximal branches, leading to progressive stenosis and occlusion, often clinically manifesting as ischemic or hemorrhagic stroke with high rates of morbidity and mortality. On cerebral angiography, the formation of collateral vessels has the appearance of a puff of smoke (moyamoya in Japanese), which became more conspicuous with the refinement of modern imaging techniques. When there is associated disease, it is known as moyamoya syndrome. Treatments are currently limited, although surgical revascularization may prevent ischemic events and preserve quality of life. In this review, we summarize recent advances in moyamoya disease, covering aspects of epidemiology, etiology, presentation, imaging, and treatment strategies.
Background
Cerebellar mutism is usually associated with posterior fossa tumor surgery.
Case Report
We report a case of a 17-year-old female, presented with headache and tremor after hemorrhage from a ...vermian arteriovenous malformation. She was successfully treated by embolization; however, on immediate postoperative, she developed persistent mutism. To the best authors’ knowledge, this is the first case of cerebellar mutism after endovascular treatment reported in the medical literature.
Conclusion
The endovascular approach may have the same potential of complication of conventional surgery; therefore, more study is necessary to clarify the role and limits of this technique to treat cerebellar arteriovenous malformation.
Dural arteriovenous fistulas (DAVFs) are characterized by pathologic shunts between meningeal arteries and venous sinuses, without nidus. Although many lesions are considered idiopathic, there may be ...an association with inflammatory processes, including sinus thrombosis, venous hypertension, craniotomy, trauma, and infections.
A 50-year-old woman with an infectious complication of a dental implant evolved with an occipital DAVF. To our knowledge, this is the first case of a dental implant-related DAVF reported in the medical literature.
Physicians should be aware of the possibility of DAVF formation after craniofacial infections. Better understanding of the etiopathogenesis of this type of lesion is required to avoid and treat potential complications.
Thromboembolism is the most frequent complication in endovascular treatment of intracranial aneurysms, causing disability and death. As stent retrievers have achieved high rates of arterial ...recanalization in the management of ischemic stroke, these devices were tested as rescue therapy of thromboembolism during aneurysm embolization. We retrospectively analyzed 10 consecutive patients with transprocedural arterial occlusion, treated with mechanical thrombectomy at a single center. Good angiographic recanalization was achieved in eight cases, mTICI 3, 2b and 2a in five, three and two patients, respectively, without additional complications or any deaths. Five patients showed complete recovery (mRS 0) and all patients showed improvement of disability (average mRS 1.1) over a mean follow-up period of 31 months. Eight patients had good clinical recovery, while two remained with deficits (mRS 3 and 4). The study found that the stent retriever is a valuable, rapid and effective tool for restoring blood flow, improving the safety of endovascular treatment.
PHACE(S) syndrome is a neurocutaneous syndrome with a wide array of presentations. The most known and present trait is facial hemangioma > 5 cm. The name is an acronym for Posterior fossa ...malformations, infantile Hemangiomas, Arterial anomalies, aortic Coarctation, Eye abnormalities, and middle-line malformations of the Sternum. The exact etiopathogenic mechanism of this syndrome is not fully understood, and its treatment depends on detailed and individualized assessment. The aim of this paper is to describe a child with a throat hemangioma, vascular malformations, cognitive delay, and other anomalies to illustrate the neuroimaging found in this syndrome.
