Developmental venous anomalies (DVA) are congenital aberrations in the cerebral venous system reflecting failure of normal embryogenesis. They are considered the most common intracranial vascular malformation. Although they are generally regarded as benign entities, their clinical significance remains controversial--case reports do exist considering DVA to be the origin of thrombosis, cerebral ischemia, and hemorrhage. We report a 26-year-old patient suffering from thrombosis of a DVA.

: Vein of Galen aneurysmal malformations (VGAMs) represent the most common vascular malformations of the brain at the pediatric age. Comprehension of its angioarchitecture and clinical features may influence their treatment options and functional outcomes. The aim of this review is to give an update of the anatomical and technical aspects of the management of VGAMs after endovascular treatment.

During embryogenesis, endothelial cells (ECs) are generally described to arise from a common pool of progenitors termed angioblasts, which diversify through iterative steps of differentiation to form functionally distinct subtypes of ECs. A key example is the formation of lymphatic ECs (LECs), which are thought to arise largely through transdifferentiation from venous endothelium. Opposing this model, here we show that the initial expansion of mammalian LECs is primarily driven by the in situ differentiation of mesenchymal progenitors and does not require transition through an intermediate venous state.

Constipation is found in individuals with intellectual disabilities, autism, and cerebral palsy. Although generally a benign condition, it may lead to life-threatening intestinal obstruction, with or without volvulus, or to stercoral ulceration with enteritis and/or perforation. Two unusual cases of lethal chronic constipation are reported to demonstrate other very rare fatal mechanisms that may occur.

Anterior Hox genes are required for genetic identity and anterior posterior patterning of the second heart field (SHF), which contributes to the formation of the embryonic heart in vertebrates. Defective contribution of SHF cells to the arterial or venous pole of the heart is often associated with severe congenital heart defects. The mouse Cre-lox system allows the activation of expression of any gene of interest in restricted tissues.
