Lamina terminalis fenestration

Chohan et al.3 (Chohan MO, Carlson AP, Hart BL, et al: Lack of functional patency of the lamina terminalis after fenestration following clipping of anterior circulation aneurysms. Clinical article. J Neurosurg 119:629–633, September 2013). In their study, the authors injected, on postoperative Day 1 following clipping of anterior circulation aneurysms, an iodine-based contrast agent intraventricularly to assess, with CT imaging, the flow into the basal cisterns through a fenestrated lamina terminalis. They concluded that fenestration of the lamina terminalis (FLT) did not result in functional patency of the lamina terminalis when performed as part of surgical clipping for ruptured aneurysms. We have some remarks and criticisms regarding this article, which leads to clear-cut conclusions.
