title: Heuber Maneuver in Evaluation of Direct Carotid-Cavernous Fistula.
abstract: Carotid-cavernous fistulas are abnormal communications between the carotid system and the cavernous sinus. Elevated venous pressure produces congestion in the orbit with resultant transudation of fluid and increased intraocular pressure, thereby leading to secondary glaucoma which may result in visual loss. Immediate treatment is hence, warranted in these cases. The planning of endovascular management is dependent on many parameters, the most important of which are the size and location of the fistula. Since these are high-flow fistulas, assessment requires certain manoeuvers. Heuber manoeuver is one of the manoeuvers used to demonstrate the size of the fistula.
