Pathogenesis of Vascular Anomalies

Hereditary vascular anomalies: new insights into their pathogenesis.

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...

Vascular anomalies

Management of vascular anomalies is an emerging multidisciplinary, super-specialisation field involving several surgical, medical and radiological specialties. Over the years, development in this field has been limited because of complex nomenclature and lack of consensus on the best practice for treatment of some of the more complex vascular anomalies. It was only in 1996 that the Internationa...

Classification of vascular anomalies.

Portosystemic vascular anomalies.

Portovascular anomalies are most commonly seen as congenital communications in dogs and cats. Fixation, whether surgical or interventional, should be considered in all cases for which it is possible to improve perfusion to the liver, and ultimately liver function. Medical management before fixation is always recommended. If surgery is not recommended or not possible, long-term medical managemen...

CME Vascular Anomalies: Hemangiomas

Mulliken and Glowacki categorized vascular anomalies as either hemangiomas or malformations, with the former being the most common tumor of infancy. Despite distinct clinical, radiologic, and histologic findings, the two major types of vascular lesions are often confused. This complicates both patient care and interpretation of the medical literature. A thorough understanding of the presentatio...
