Imaging evaluation and endovascular therapy of carotidian territory angiomas

Vasoformative lesions are most common malformations of the cranial and cervical tissue in infants and small children. Among the high incidence of vasoformative injuries of general population meets the hemangiomas. Hemangiomas are prominent lesions, circumscribed, red, often lobe, typically found in females (sex ratio of 3:1 in most studies found in medical literature) (4). Is 10-12% incidence of hemangiomas in infants, preterm infants with a birth weight over 1500 g and term newborns. Amir and colaborators (1986) quotes an incidence of 23% in premature infants with birth weight below 1000 g (4). Most hemangiomas are distinct lesions during the first six weeks of life and proliferate within the first 8-12 months. Hemangiomas are often isolated lesions (80%), while 20% of cases have multiple location. Offices most common occurrence and development of hemangiomas are the head and neck region, followed by the trunk and extremities. Larynx-trachea impairment may be present up to 50% of cases, in combination with other cranial hemangiomas. Viewed medical literature describes many scientific controversies concerning the natural progression of hemangiomas, characterized by a lack of consensus with regard to be managed. Lack of consistency of the findings of the literature on behavior therapy for hemangiomas derive, in general, diagnostic confusion between hemangiomas and vascular malformations, and absence of reliable data on the natural evolution of the disease. The classic articles, the term capillary hemangioma described fine porto-portal malformation, and the terms of nevi and hemangiomas cavernous hemangioma describe what define true today. The first major step in clarifying the nomenclature of the hemangioma was performed by Mulliken et al. who imagined a biological classification scheme based on different clinical developments and endothelial proliferative activity of hemangiomas versus vascular malformations. Hemangiomas, often called juvenile or infantile hemangiomas for clarity, are benign tumors characterized by a phase of rapid proliferation and early during the first year of life occur endothelial hyperplasia followed by an involution phase that may be spread over a variable number of years. Mulliken-Glowaki Classification (1982) defines a systematic difference between hemangiomas and vascular malformations .The scheme is based on histopathological classification has been improved by immunohistochemical characterization of hemangiomas for each developmental phase Modern techniques of anesthesia, laser methods, medical treatment and surgical intervention have enabled effective treatment for residual lesions so that the psychological impact is minimized. Consulted literature shows that 25-40% of hemangiomas are evolving unacceptable cosmetic effects, which can however be improved by medical intervention and / or surgery. Despite the unprecedented development of facial hemangiomas therapeutic approach, especially after the adoption of international classification described by Mulliken and Glowacki, the treatment of these diseases is still a pioneer. Research literature has allowed us to determine that approximately 60% of published studies are descriptions of the event and not extensive clinical trials. The remaining 6% is review study investigated retrospective studies 5% are
