A rare case of retroperitoneal hematoma after open partial nephrectomy was successfully treated. The bleeding stemmed from an intrarenal pseudoaneurysm, which was embolized via angiography.

Area of Science:

  • Urology
  • Vascular Surgery
  • Interventional Radiology

Background:

  • Hemorrhage is a known complication of partial nephrectomy.
  • Intrarenal pseudoaneurysms can cause bleeding after renal surgery.
  • Hemorrhage from pseudoaneurysms after open partial nephrectomy is uncommon.

Observation:

  • A 56-year-old woman developed a retroperitoneal hematoma 2.5 weeks post-left partial nephrectomy.
  • The patient had undergone surgery for renal cell carcinoma.
  • The hematoma was associated with an intrarenal pseudoaneurysm.

Findings:

  • The intrarenal pseudoaneurysm was identified using percutaneous renal arterial angiography.
  • Selective embolization of the pseudoaneurysmal branch was performed.

  • The procedure successfully controlled the hemorrhage.

    • Implications:

    • This case highlights a rare but serious complication of open partial nephrectomy.
    • Percutaneous arterial embolization is an effective treatment for intrarenal pseudoaneurysms.
    • Angiographic embolization offers a minimally invasive option for managing post-nephrectomy hemorrhage.
