Nutcracker phenomenon causing hematuria can lead to severe anemia. Expandable metallic stent (EMS) placement across the left renal vein effectively resolved anemia in a patient refractory to other treatments.

Area of Science:

  • Nephrology
  • Interventional Radiology
  • Vascular Surgery

Background:

  • The nutcracker phenomenon, a rare vascular condition, can cause significant renal vein compression, leading to hematuria and anemia.
  • Standard treatments for persistent hematuria due to the nutcracker phenomenon, including hemostatic agents and chemical ablation, may not always be effective.

Observation:

  • A 40-year-old woman with symptomatic gross hematuria from the nutcracker phenomenon developed severe anemia (hematocrit 17%) despite initial treatments.
  • Persistent hematuria and anemia necessitated an alternative therapeutic approach.

Findings:

  • Expandable metallic stent (EMS) placement across the left renal vein was performed as a minimally invasive intervention.
  • Following EMS placement, the patient's severe anemia resolved, although mild hematuria persisted.

Implications:

  • Expandable metallic stent (EMS) placement offers a viable, minimally invasive therapeutic option for managing the nutcracker phenomenon, particularly in cases refractory to conventional treatments.
  • This intervention can effectively address debilitating anemia secondary to the nutcracker phenomenon, improving patient outcomes.
