Clinical characteristics of acute renal infarction: an analysis of 15 cases / 中华全科医师杂志

ABSTRACT

Clinical data of 15 patients diagnosed with acute renal infarction (ARI) in Affiliated Zhongshan Hospital of Dalian University from Jan 2011 to Dec 2021 were retrospectively analyzed. Of the included 15 patients, there were 14 cases of cardiac origin and 1 case of antiphospholipid syndrome. We found that there were 12 cases of atrial fibrillation, 2 cases of atrial premature beats, 12 cases of elevated level of D-dimer, 15 cases of elevated level of LDH, 11 cases of positive urine occult blood and positive urine protein. Among the 15 patients, catheter-directed thrombolysis was performed in 4 cases, of which 3 cases were revascularized successfully, intravenous thrombolysis in 2 cases and alone anticoagulation therapy in 9 cases. It is suggested that CECT or CTA can assist the early diagnosis of ARI especially in patients with acute onset and persistent abdominal pain with high risk factors of thromboembolism, high levels of LDH, microscopic hematuria and/or proteinuria. Despite prolonged embolic ischemia, try to reconstruct blood flow to save the kidney as much as possible. Late standardized anticoagulant therapy is of critical importance to prevent recurrent embolic episodes.
