title: Arteriovenous shunting in quadriplegia.
abstract: Arterio-venous shunting has been demonstrated in the limbs of ten subjects with traumatic quadriplegia, as shown by increased venous oxygen concentration and a Doppler sonogram pattern indicative of continuous forward flow. This phenomenon is similar to that seen in the diabetic neuropathic foot, suggesting that autonomic dysfunction is a major factor in the development of foot ulceration in the quadriplegic and in the diabetic.
