경피적 요골동맥도관 후 발생한 수지괴사

Anesthegiologists commonly use arterial cannulation for both close blood pressure monitoring and repeated blood sampling for gas analysis. Radial artery cannulation is generally thought of as a safe and uncomplicated procedure, however, some possible complications have been reported. These include bleeding, hematoma, infection, pseudoaneurysm and thromboembolism, which do not usually result in any serious clinical problems. Although it is not common, thromboembolism could be serious because it can lead to digital ischemia and necrosis. We report here a case of finger necrosis following radial artery cannulation in a patient who underwent radical hysterectomy under general anesthesia.
