Developmental venous anomalies (DVAs) are cited as the most common intracranial vascular anomaly. In the majority of cases, it has a benign clinical course, and complications such as intracranial hemorrhage (ICH) are rarely reported. In the rare cases of DVAs presenting ICH, the causes of hemorrhage are usually by a combined vascular anomaly, mostly cavernous malformation (CM) or complicated DVAs, such as thrombosis in the vein of DVAs. We report a rare case of uncomplicated DVA presenting hemorrhage without accompanied vascular anomaly, such as CM. The cause of hemorrhage is suggested to be a specific form of DVA, arterialized DVA. Arterialized DVAs should be noted that they have a greater risk of hemorrhage than classic DVAs.

The performance of a unique silicone hot-melt bonding solution for device fabrications is described. Inherent attributes of traditional silicones including water repellency, chemical resistance and durability are augmented with automated precision hot-melt delivery. Other properties include instant room-temperature adhesion to provide ingress and impact protection while allowing manufacturers the benefit of reworkability and design flexibility.
