IntroductionContinuous peripheral nerve block achieves good pain control. However, uncontrolled pain despite an effective block in the target areas of the nerve can be an early sign of ischemia. We report a case of iatrogenic injury to the axillary artery during shoulder surgery in a patient who had continuous supraclavicular block and demonstrate how vigilant monitoring helped the diagnosis and resulted in timely management of upper limb ischemia.Case ReportA 58-year-old female underwent total revision surgery of her right shoulder under continuous supraclavicular block. Postoperatively, she complained of pain along the medial side of her forearm despite clinical evidence of nerve block. Continuous neurovascular monitoring and timely angiography confirmed axillary artery injury, and subsequent vascular repair saved the patient's limb.ConclusionIatrogenic injuries to vessels or nerves sometimes occur during orthopedic surgical procedures. Regional anesthesia can mask and delay the onset of these symptoms. Postoperative monitoring and the ability to differentiate between the effects of local anesthetics and the body's response to ischemia are important for avoiding postoperative complications. This case report aims to improve awareness about the need for vigilant monitoring of the distal pulses after peripheral nerve blocks.
