Comment on: Carotid-cavernous fistula: current concepts in aetiology, investigation and management

Abstract

We appreciate the comments by Gout et al. [1] We agree that some superior ophthalmic veins are extremely fragile and difficult to cannulate, even with the available microcatheters (see supplemental video). We also agree that performing a Valsalva maneuver may make it easier to insert the microcatheter into the vessel. One still must be careful not to perforate the vessel as the catheter is advanced, as catastrophic visual complications can result, as emphasized in our manuscript and in the paper by Leibovitch et al., which we (and Gout et al.) have referenced [2].

“…Electrical injury is not uncommon as many people come into contact with electricity on daily basis. However only few cases of electrical cataract have been reported because very few patients survive after a high electric voltage, that is needed to induce cataract [1][2][3]. Most of the cases of electrical injury have no visual complaints in the early Electronic supplementary material The online version of this article (https://doi.org/10.1038/s41433-018-0113-4) contains supplementary material, which is available to authorized users.…”
