The Nutcracker Syndrome as a Rare Cause of Chronic Abdominal Pain: A Case Report

Renal vein entrapment, named nutcracker phenomenon, is a contraction of renal vein between abdominal aorta and superior mesenteric artery. Patients can be asymptomatic or clinically manifested, called nutcracker syndrome. Proteinuria, hematuria, flank pain, varicocele in males and pelvic congestion in females are reported in such patients.
The current report presented an eight-year-old girl with microscopic hematuria and chronic abdominal pain along with short review of anatomy, pathophysiology, clinical significance and management of this syndrome.
The nutcracker syndrome should be differentiated from unexplained chronic abdominal pain.
