Clinical Trial
Endovascular treatment of posttraumatic carotid-cavernous fistulas and pseudoaneurysms with covered stents.
The treatment of posttraumatic direct carotid-cavernous fistulas (TCCFs) with detachable balloons (DBs) is associated with relatively high recanalization rate. The aim of this study was to evaluate the feasibility of using covered stents in patients with posttraumatic carotid-cavernous fistulas (CCFs) and pseudoaneurysms. ⋯ These preliminary results indicate that the use of a covered stent is a feasible procedure for the treatment CCFs and pseudoaneurysms.

Dolichoectasia (DE) is a vasculopathy that consists of abnormal elongation and dilatation of arteries. The objective of this study is to evaluate the frequency of DE in an unselected population and assess different diagnostic methods. ⋯ A TCV-adjusted intracranial arterial diameter ≥2 SD is proposed as a useful DE definition. The variability in the prevalence of DE depending on the methods used underscores the need to agree on a reliable, universal definition of DE.

Reversible lesions on magnetic resonance imaging that transiently restrict diffusion in the splenium of the corpus callosum (SCC) without any other accompanying lesions have been reported in various clinical conditions. We offer the first report of postpartum cerebral angiopathy with reversible SCC lesions.
