Congenital Venous Malformations: A Clinico-Pathological Review
Journal Title: International Journal of Medical Research Professionals - Year 2017, Vol 3, Issue 4
Abstract
Vascular anomalies have been classified in different ways based on clinical, pathological and embryological factors. In 1996, the International Society for the study of vascular anomalies proposed a classification based on that originally published by Mulliken and Glowacki, dividing these vascular lesions into vascular anomalies and tumors. Vascular tumors include hemangiomas and other proliferative lesions. They proliferate largely by endothelial hyperplasia. Vascular malformations may be simple and combined. They never regress and persist and enlarge during later life. Amongst the vascular lesions venous malformations (VM) are distinct lesions originating embryologically from primitive vasoformative tissue which later differentiate into venous system. These lesions mostly occurring subcutaneously and intramuscular are often misdiagnosed as hemangiomas and A-V malformations. They have definite clinical features and can be diagnosed clinically and confirmed by MRI imaging. They can be treated well either by sclerotherapy, Nd-YAG laser application or Surgical excision with good results. Intracranial and gastrointestinal lesions often present with bleeding and require adequate and appropriate care based on the location of the lesions. Our particular stress in this review which is based on our personal experiences is for appropriate clinical diagnosis of these vascular malformations, which may be confirmed by MRI imaging and can be adequately and safely treated by surgical excision. We observed that these lesions are very often misdiagnosed clinically due to two reasons: 1) Even though they are of congenital and embryonic origin they report during 2nd or 3rd decade. 2) The overlying skin doesn’t show any changes except some bluish discoloration due to prominent dermal veins. 3) Sign of blanching, sign of compressibility, local warmth or pulsations seen in majority of vascular lesions are not usually seen in these cases.
