Anterior Nutcracker syndrome in a young male patient: a case report and review of literature.

Introduction And Importance: The left renal vein (LRV) is affected by a venous compression syndrome called Nutcracker syndrome (NCS). This syndrome is characterized by extrinsic compression of the LRV, which usually occurs between aorta and superior mesenteric artery. It is a rare and under-diagnosed condition, more prevalent in females and that, if left untreated, can lead to severe problems. There are no clear guidelines regarding management. Therefore, the authors report this rare case and its symptoms in male patient and they display current management options.

Case Presentation: NCS was observed during computer tomography in a male patient presented with persistent left flank pain and associated haematuria. Ultrasound for left scrotum demonstrated left moderate-sized varicocele. The left varicocele testis unit was 1.6 mm and during the Valsalva manoeuvre in the supine position the testis unit was 2 mm. LRV compression between abdominal aorta and superior mesenteric artery was identified by computer tomography imaging and therefore, diagnosis of NCS was confirmed.

Clinical Discussion: The actual prevalence is unclear, and incidence rates have been observed to fluctuate among age group and more prevalent in women. Main symptoms include haematuria, left flank discomfort, varicocele in men, proteinuria and anaemia. Depending on severity of symptoms, management might range from conservative care to surgery.

Conclusion: This treatment strategy was effective in reducing the symptoms of the patients. In young patients, conservative treatment is advised for a fair amount of time. However, more studies on how much the authors should wait before considering surgery is important.
