To the Editor.—Septicemia secondary to radial artery catheterization is recognized but uncommon. Recommendations for treatment include removal of the catheter and administration of parenteral antibiotics.1 One patient with staphylococcal septicemia from this source did not respond to this conventional therapy and additionally required excision of the infected artery to effect resolution.
Report of a Case.—A 58-year-old man was admitted for elective excision of the left upper pulmonary lobe for bronchogenic squamous carcinoma. Preoperative pulmonary function was severely impaired and necessary perioperative arterial monitoring was achieved with a percutaneous Teflon catheter.
