To the Editor,

Use of invasive blood pressure monitoring is an integral aspect of management in both operative and critically ill patients. It allows for beat-to-beat measurement of blood pressure and can be utilized to measure dynamic variables such as pulse pressure variation.1 Fortunately, the radial artery is usually an easily accessible and dependable site for direct cannulation for invasive blood pressure monitoring. Nevertheless, to reliably interpret the blood pressure data from it, one must ensure the integrity of the pressure monitoring system components, and assume that no obstructions at the level of the catheter or the proximal vasculature exist.

Herein we report a 69-yr-old female admitted to our cardiac surgical intensive care unit following coronary artery bypass grafting. She had known coronary artery disease, hypertension, and dyslipidemia. Preoperatively, the patient underwent an upper extremity vascular investigation prompted by reported paresthesia and weakness in...
