Renal Artery Spasm: A Cause of Acute Kidney Injury Subsequent to Abdominal Surgery for Primary Mature Renal Teratoma

Pdf Summary

This case report discusses a rare condition of renal teratoma, a benign tumor containing mixed tissues, particularly in the abdomen. A 4-month-old baby girl was admitted to the hospital with an abdominal mass and hypertension. The patient underwent surgery, which resulted in acute kidney injury (AKI) believed to be caused by renal artery spasm. The article emphasizes the importance of duplex ultrasound examination in detecting and monitoring the spasm. The initial ultrasound scan revealed significantly increased velocities in the mid to distal renal artery, suggesting vasoconstriction. However, a repeat scan performed two days later showed the resolution of the spasm, indicating improvement in kidney function. The patient's kidney function eventually fully recovered. Renal artery spasm is a rare but potential cause of AKI after major abdominal surgery, and its detection may be influenced by the timing of diagnostic examinations. The case report highlights the need for further research on the onset and duration of renal artery spasm and suggests the use of duplex ultrasound to monitor patients at risk of vasospasm. Understanding this condition can help improve patient outcomes and guide appropriate interventions.
