Arterial Pressure Monitoring During Cardiopulmonary Bypass Using Axillary Arterial Cannulation

Abstract

W g EMORAL ARTERIAL cannulation had been used as the alternate source of arterial inflow for cardiopulmonary ypass (CPB) when the ascending aorta or arch was unsuitable or various reasons. Right, or rarely left, axillary arterial canulations have become more common, especially when the emoral arteries are not available for arterial cannulation due to evere iliofemoral arterial disease1 or in patients who have evere atherosclerotic disease of the descending thoracic aorta ith floating debris that precludes safe retrograde arterial perusion.2 Right axillary artery cannulation may be the arterial nflow of choice in patients with aortic dissections and aortic neurysms3,4 when selective cerebral perfusion may be necesary during deep hypothermic circulatory arrest (DHCA).5 The uthors report a case in which monitoring of the ipsilateral adial arterial pressure in a patient on CPB using axillary annulation resulted in falsely elevated arterial blood pressures hat led to inappropriate hemodynamic management and hyoxic cerebral injury.
