Evaluation of Clinical and Radiological Findings in Patients Diagnosed with Acute Renal Infarction, Descriptive Research, Case Series

Objective: Renal infarction is a rare but clinically significant condition caused by renal artery occlusion, which can lead to permanent renal parenchymal damage. This study aimed to present the demographic, etiological, treatment, and follow-up data of patients diagnosed with renal infarction. Material and Methods: Medical records of patients who presented to our clinic with acute renal infarction between January 2021 and 2024 were retrospectively reviewed. Demographic characteristics, laboratory findings, etiological evaluations, treatment, and follow-up data were obtained from hospital records. Diagnosis was confirmed based on clinical findings, elevated serum LDH, and contrast-enhanced CT. Cardiac, hematological, and genetic evaluations were performed when necessary. Renal function and treatment response were monitored. Ethical approval was obtained from Van Yüzüncü Yıl University (February 4, 2025; no: 2025/01-13). Results: A total of 20 patients were included. Mean age was 64.3±11.3 years. Renal infarction was right-sided in 10, left-sided in 8, and bilateral in 2 patients. Hypertension (60%) and atrial fibrillation (20%) were the most common comorbidities. Eight patients with total renal infarction underwent renal angiography and percutaneous transluminal angioplasty (PTA). Mean follow-up was 10 months. Chronic kidney disease developed in 2 patients. Among PTA patients, renal function improved in 6, while 2 developed renal atrophy. In patients treated with anticoagulation alone, renal function was preserved in half. Conclusion: Early diagnosis, timely interventional procedures, and appropriate anticoagulant therapy significantly reduce renal function loss in patients with renal infarction.
