When proximal arterial control cannot be obtained by standard methods, it may be achieved safely and bloodlessly by intraluminal routes with balloon catheters, hemostatic sheaths, and catheter-guide wire techniques. This method was used successfully in 20 patients to achieve proximal arterial control without complications in a variety of locations. Use of this method or its modifications may facilitate and simplify a variety of vascular operations that would otherwise be difficult or hazardous.
