Abstract:
Background The International Society for the Study of Vascular Anomalies (ISSVA) categorizes vascular anomalies into vascular tumors and vascular malformations. Vascular malformations are further divided into slow-flow (venous, lymphatic, and capillary malformation) and fast-flow malformations (arteriovenous malformation and arteriovenous fistula). This interdisciplinary classification has therapeutic implications. Methods The objective of this article is to provide concise information about the current terminology and treatment strategies of peripheral vascular malformations, based on the cur

✓ In this article the authors report the case of a mixed cerebrovascular malformation in which a true arteriovenous malformation (AVM), harboring a nidus, is associated with a venous malformation that serves as the draining vein for the nidus. Despite the authors' preoperative rationale for exclusive extirpation of the AVM, an inadvertent injury and the obliteration of the venous malformation generated delayed postoperative neurological deterioration, which could clearly be attributed to venous hemorrhagic infarction.

Abstract:
Arteriovenous malformation (AVM) results from errors in vascular development during embryogenesis; absent capillary beds lead to shunting directly from the arterial to venous circulation. Although it is common in the head and neck region, Arteriovenous malformations (AVM) of the external ear are relatively uncommon lesions. They typically present during childhood. We report a case of giant AVM of the right pinna in 8 years child, which are very rarely seen. We discussing the definition, clinical findings, diagnostic approaches of arteriovenous malformations.

Abstract:
Klippel-Trénaunay syndrome (KTS) is a rare vascular congenital anomaly affecting less than 200,000 people in the United States. Vascular malformations associated with KTS tend to affect slow flow systems: venous, capillary, and lymphatic systems. The nature of the syndrome leads to a higher risk for the development of arteriovenous malformations. Our case presentation describes a patient with KTS and an associated rare presentation of intraventricular arteriovenous malformation (AVM).

Abstract:
Arteriovenous malformations are one of the variants of congenital vascular malformations resulting from a defect in the development of the arterial and venous systems with the formation of direct messages between vessels of different diameters and shunting of blood with high velocity characteristics from the arterial to the venous part of the vascular system. Arteriovenous malformations are characterized by a wide variety of clinical manifestations and in some cases may be accompanied by severe circulatory disorders.

Abstract:
AbstractBackground and purpose: Brain arteriovenous malformations (AVM) are uncommon vascular lesions with the risk of hemorrhage, epileptic seizures, neurological deficits, and headache. Comparing the risks of the natural history and that of preventive treatment, a recent study has found observation more beneficial than treatment for unruptured AVMs. This study, however, did not consider the long-term impact of carrying a brain AVM on everyday activities. In this study we analyzed the Quality Of Life (QOL) of patients with untreated AVMs, a measure increasingly used in clinical trials to asses this kind of impact.Methods: We enrolled 36 patients with unruptured, untreated brain AVM from our hospital database and measured their QOL retrospectively using the EQ-5D-5L questionnaire. As a control group we used the results of the Research Report, a nationwide study based on the quality of life of 5534 healthy Hungarians in 2002. Due to the low number of cases, statistical analysis could not be made.Results: Headache proved to be the most common AVM-related sign in our cohort (40%, n = 17), with a female predominance; neurological deficit was detected in 33% (n = 14), while epileptic seizures occurred in 26% (n = 11), more commonly affecting male subjects. Anxiety and discomfort seemed to be the most prevalent influencing factors on QOL, especially in the youngest age group (18–34 years). Female subjects showed a greater dependence than men in all age groups, though males had a more significant impairment in their usual activities. Older patients were affected more significantly in their self-care and usual activities compared with the younger population.Conclusions: Untreated AVMs have a significant negative impact on patients carrying unruptured brain AVMs, as proved by QOL assessment. Beside neurological deficits, this impact should also be considered in the therapeutic decision.

Abstract:
The spectrum of paediatric neurovascular disorders includes several conditions like arteriovenous malformation (AVM), aneurysm, and cavernous malformations that occur in adults. Despite the similarity in pathology there are differences in presentation, location, and management of vascular disorders in children as compared to adults. There are disorders that are peculiar to the paediatric population like vein of Galen malformations or intraventricular haemorrhage in premature infants and others that occur predominantly in children though are seen in adults such as moya disorder. Recent advances in endovascular therapy, radiosurgery, and multimodality management of vascular lesions have increased the options available to manage these lesions in children. Identification of underlying gene abnormalities in cavernomas and moya moya disease promises to shed new light on the pathogenesis of these disorders. The common neurovascular disorders seen in the paediatric population are discussed in this chapter with the focus on those seen predominantly in children.

Abstract:
Abstract A cerebral arteriovenous malformation (AVM) is a congenital vascular lesion of the brain composed of a complex tangle of arteries and veins, which are linked by one or more fistulae [1]. Arterial blood is shunted through the AVM directly to the venous system, precluding arterial blood from perfusing adjacent brain structures. The most common presentation of this disease is cerebral hemorrhage secondary to AVM rupture, with an associated mortality of 15% and a morbidity of 50% [1]. One modality to treat this pathology is endovascular embolization. Generally, endovascular embolization s
