• Leriche syndrome
• hyperkalemia
• hemodialysis
• ecg changes
• obturation of great vessels

A hemodialysis patient suffered from circulation failure due to a low output syndrome caused by a hyperkalemia (9.9 mu mol/l) with typical ecg signs. An emergency hemodialysis was started. After 2 h ecg signs of hypokalemia (2.1 mu mol/l) were detectable. Hemodialysis was stopped. 2 h later, serum potassium rose to 6.2 mu mol/l. An obturation of the aorta and the inferior caval vein with perfusion through collateral vessels of the lower body side was obvious, resulting into a faster electrolyte correction in the upper and a delayed correction in the lower body side with a rebound in the upper compartment. Dialysis time and dialysate potassium (4.0 mu mol/l) were increased. Furthermore no potassium problems occurred.
