BACKGROUND Even though vascular malformations are well categorized, further details are relatively unknown. Of treated patients regarding the frequency, demographic distributions, and other related factors by multivariate regression analyses in proportion to total vascular malformations, methods of treatment and how to manage them have not been elucidated thoroughly. METHODS From January 2006...

V ascular malformations result from the aberrant development of vascular elements during embryogenesis and fetal maturation. Despite apparent endothelial quiescence, some vascular malformations can expand rapidly during adolescence or pregnancy, after a surgical procedure, or in response to trauma. The pathogenesis of vascular malformations is not well clarified, but their formation and progres...

Vascular malformations are described in 25 members of one affected family. Most of these lesions were cavernous hemangiomas, but arteriovenous malformations and capillary hemangiomas were also microscopically observed in some specimens. The five generation pedigree suggests the vascular malformations are genetically determined on the basis of a dominant inherited trait.

• Vascular supply of the spinal cord is by anterior spinal artery in the median fissure and 2 posterior spinal arteries supplemented by medullary branches of intervertebral artery. The intervertebral artery gives s dural and medullary branches. The dural branches persist through life, however, the majority of medullary arteries involute and by adult life only 6-10 medullary arteries persist. Th...

Identification and treatment of vascular malformations is a challenging endeavor for physicians, especially given the great concern and anxiety created for patients and their families. The goal of this article is to provide a review of vascular malformations, organized by subtype, including capillary, venous, lymphatic and arteriovenous malformations. Only by developing a clear understanding of...

INTRODUCTION Haemangiomas in children usually involute spontaneously and surgical treatment is exceptional. Vascular malformations do not regress spontaneously and resection may become necessary. We present a series of surgically treated face and neck vascular anomalies during a 9-year period, assessing the epidemiology, presenting signs and symptoms, diagnostic modalities, indications for surg...

The vast majority of cerebral vascular malformations reported in the antenatal literature are aneurysmal malformations of the vein of Galen. Other types of intracranial vascular malformations are exceptional in fetuses. The authors present a case of prenatal diagnosis of intracranial pial arteriovenous fistula, not involving the vein of Galen and not showing abnormal intracranial anatomic featu...

Increased understanding of the mechanisms of angiogenesis and lymphangiogenesis has provided a glimpse at some of the molecules involved in the pathophysiology of hemangiomas and vascular malformations. This review focuses on recent advances in our understanding of the mechanisms of angiogenesis/lymphangiogenesis and the differentiation of arterial, venous, and lymphatic vessels. We integrate t...

Genetic factors play a critical role in the pathogenesis of vascular anomalies. Significant advances have been made in recent years in identifying the genetic and molecular determinants of a variety of vascular anomalies using a molecular genetic approach. Several genes for vascular anomalies have been identified. These genes include AGGF1 for Klippel-Trenaunay syndrome, RASA1 for capillary mal...

In this case report, we discuss the presentation, physical examination, imaging studies, and diagnosis of a rare vascular lymphatic malformation in upper limb 3-year old child. Vascular malformations are uncommon conditions, which can be misidentified as malignant tumours children at first glance. The image study is essential to identify them decide best treatment strategy each situation.
