title: Contrast agent-induced thrombophlebitis following leg phlebography: meglumine loxaglate versus meglumine lothalamate.
abstract: A comparison was made of the incidence of venous thrombophlebitis resulting from the use of a high-osmolality contrast medium (Conray 60%, meglumine ioxaglate) and a low-osmolality contrast medium (Hexabrix 59%, meglumine iothalamate). In 30 patients with varicose veins, Conray was injected into one leg and Hexabrix into the other. The incidence of thrombophlebitis was then determined using the iodine-125 fibrinogen uptake test in a prospective, randomized, double-blind study. There was significantly less thrombophlebitis with Hexabrix than with Conray and the authors conclude that Hexabrix is safer for phlebography. Hexabrix is also stable in solution, only slightly more expensive than Conray, and one fifth the cost of metrizamide.
