Group A, 17 patients (14 men, 3 women), mean age 22 years, had a pulse oximeter reading of greater than 92% and an arteriogram, but had no surgical intervention. There was no adverse outcome or episodes of adverse outcome. None had any adverse sequelae. Group B, 11 patients (8 men, 3 women), mean age 24 years, had pulse oximetry readings from 0% to 88%; all patients in this group required vascular reconstructive surgery based on history, physical examination, and arteriogram; two lost their limb(s).
