Radial artery pseudoaneurysm formation after cat bite to the wrist.

Pseudoaneurysms may occur in the groin after catheterization of the femoral artery but may also occur in arteriovenous shunting for dialysis after placement of indwelling catheters or after direct trauma to an artery. We report a unique cause of radial artery pseudoaneurysm at the wrist related to a cat bite sustained by an elderly woman. The patient underwent successful operative repair of the aneurysm, with ligation of the radial artery.
