A 55-year-old male suffering from acute abdominal aortic occlusion due to iatrogenic aortic dissection was urgently admitted to hospital. An axillo-bifemoral bypass was constructed 6 hours from the onset of dissection. Before and after revascularization, blood samples were repeatedly obtained from a systemic artery and femoral vein. The arterial potassium concentration gradually increased, reaching 7.3 mM/L. Oliguria and arrhythmias occurred, and the left lower limb became rigid 3 hours after reperfusion. The femoral artery and vein were clamped and within 30 minutes, the arterial potassium concentration fell to 4.8 mM/L. The urine output increased. The left lower limb was amputated, and the patient survived. Immediately following revascularization, hyperkalemia may occur. Clamping of the afferent and efferent vessels is recommended as a simple and practical technique to quickly control life-threatening hyperkalemia.
