[Three patients with a kidney infarct].

Two patients, one 76-year-old-man and one 79-year-old-woman with cardiovascular disease and one 36-year-old-man with Factor-V-Leiden deficiency (activated protein C-resistance) had abdominal pain and elevation of LDH levels. With abdominal CT scan kidney infarction was diagnosed. In two cases a selective kidney arteriography was performed to confirm the diagnosis. Treatment consisted of (re)starting anticoagulant therapy. In unexplained abdominal pain with insufficiently specific results of physical examination combined with a rapid rise of the LDH and sometimes of the serum creatinine, a kidney infarction should be considered in the differential diagnosis.
