Published: March 1999

We present a patient with a rare cerebrovascular malformation consisting of a typical arteriovenous malformation (AVM) with a nidus and a venous malformation (VM) in a single lesion. The AVM component was successfully obliterated by radiosurgery, whereas the VM was completely preserved. Radiosurgery can be an effective treatment technique for treating this type of malformation because it allows targeted obliteration of the AVM yet carries a low risk of damaging the venous drainage toward and away from the VM.

Introduction: Cerebrovascular dysfunction plays a critical role in the pathogenesis of dementia and related neurodegenerative disorders. Recent omics-driven research has revealed associations between vascular abnormalities and transcriptomic alterations in brain vascular cells, particularly endothelial cells (ECs) and pericytes (PCs). However, the impact of these molecular changes on dementia remains unclear.

Background: Delayed radiation-induced complications after stereotactic radiosurgery (SRS) for arteriovenous malformations (AVM) have scarcely been described in the literature, and their incidence, pathophysiology, and treatment remain unclear. Additionally, the literature regarding these complications is confusing. The authors present a well-documented case report describing these late complications, adding evidence to the possible common pathophysiological mechanism underlying them, and illustrating an effective treatment modality when they occur.

Background: Small-bowel angioectasia is commonly diagnosed and managed using double-balloon enteroscopy; however, rebleeding rates can vary significantly. This study aimed to identify and evaluate the clinical predictors of rebleeding in patients with small-bowel angioectasia.

Methods: This retrospective study focused on adult patients who underwent endoscopic management for small bowel vascular lesions (SBVLs).

The central nervous system (CNS) parenchyma has conventionally been believed to lack lymphatic vasculature, likely due to a non-permissive microenvironment that hinders the formation and growth of lymphatic endothelial cells (LECs). Recent findings of ectopic expression of LEC markers including Prospero Homeobox 1 (PROX1), a master regulator of lymphatic differentiation, and the vascular permeability marker Plasmalemma Vesicle Associated Protein (PLVAP), in certain glioblastoma and brain arteriovenous malformations (AVMs), has prompted investigation into their roles in cerebrovascular malformations, tumor environments, and blood-brain barrier (BBB) abnormalities. To explore the relationship between ectopic LEC properties and BBB disruption, we utilized endothelial cell-specific overexpression mutants.

We present two cases of vein of Galen aneurysmal malformation, detected in early life, with differing outcomes. This suggests that early detection of this malformation in fetuses or neonates does not necessarily indicate a poor prognosis, highlighting the need for vigilant monitoring and timely intervention to optimize outcomes.
