Clinical phenotype of adolescent and adult patients with extracranial vascular malformation. [PDF]

, 2023
BACKGROUND In recent years, genotypic characterization of congenital vascular malformations (CVM) has gained attention; however, the spectrum of clinical phenotype remains difficult to attribute to a genetic cause and is rarely described in the adult ...

Metachronous venous malformation masquerading as an obscure gastrointestinal bleed

Journal of Indian Association of Pediatric Surgeons, 2022
Vascular malformation of the gastrointestinal (GI) tract along with metachronous lesions elsewhere in the body is extremely rare. We report an unusual case of a female child, with a history of venous malformation excision over the right leg presenting ...

Endoglin prevents vascular malformation by regulating flow-induced cell migration and specification through VEGFR2 signalling

Nature Cell Biology, 2017
Loss-of-function (LOF) mutations in the endothelial cell (EC)-enriched gene endoglin (ENG) cause the human disease hereditary haemorrhagic telangiectasia-1, characterized by vascular malformations promoted by vascular endothelial growth factor A (VEGFA).

Angiographic Embolization with Histoacryl in Combination with Direct Injection of Bone Cement of an Intraosseous Venous Malformation of the Mandible: Report of a Case with 22-Year Follow-Up

Case Reports in Vascular Medicine, 2022
Vascular malformations of the maxillofacial region are unusual, and they occur more rarely in bone than in soft tissue. Mandibular intraosseous vascular lesions represent 0.5-1.0% of all bone tumors, and they are classified as venous malformation ...

HIF-1α and HIF-2α induced angiogenesis in gastrointestinal vascular malformation and reversed by thalidomide

Scientific Reports, 2016
Thalidomide is used in clinical practice to treat gastrointestinal vascular malformation (GIVM), but the pathogenesis of GIVM is not clear. Hypoxia inducible factor 1 alpha (HIF-1α) and 2 alpha (HIF-2α/EPAS1) are in the same family and act as master ...
