Summary
Endovascular embolization effectively treated blunt injury to a transplanted kidney caused by lap belt compression. This minimally invasive approach preserved graft function, offering a safe alternative to surgery for renal allograft trauma.
Area of Science:
- Nephrology
- Transplant Surgery
- Interventional Radiology
Background:
- Traumatic blunt injury to renal allografts can compromise graft survival.
- Endovascular techniques are increasingly utilized for managing renal vascular injuries.
Observation:
- A 19-year-old male experienced renal allograft injury from lap belt compression following a traffic accident.
- Angiography identified contrast extravasation from two disrupted upper pole renal artery branches.
Findings:
- Superselective embolization with microcoils successfully occluded the bleeding renal artery branches.
- Serum creatinine levels improved from a peak of 4.1 mg/dL to 2.9 mg/dL at discharge and 1.9 mg/dL at 1-year follow-up.
Implications:
- Endovascular embolization is a safe and effective treatment for blunt renal allograft injury.
- This approach avoids surgical intervention and helps preserve transplanted kidney function.
- Minimally invasive techniques offer a viable alternative for managing allograft trauma.
