Summary
Selective arterial embolization effectively stopped massive renal bleeding when imaging failed to identify the source. This minimally invasive procedure created a targeted renal infarction without causing hypertension or renal failure.
Area of Science:
- Nephrology
- Interventional Radiology
- Vascular Surgery
Background:
- Massive renal bleeding presents a diagnostic challenge, often with non-specific findings on conventional imaging.
- Identifying the precise bleeding source in idiopathic cases requires advanced interventional techniques.
Observation:
- A patient with idiopathic massive renal bleeding underwent selective arterial embolization.
- Absolute ethanol and a stainless steel coil were infused into a renal artery to occlude the bleeding source.
Findings:
- Computed tomography (CT) two weeks post-embolization confirmed a localized infarcted area in the kidney's lower pole.
- The renal infarction was successfully achieved without inducing secondary hypertension or renal failure.
Implications:
- Selective arterial embolization is a viable treatment for intractable renal hemorrhage when the bleeding source is occult.
- This technique offers a minimally invasive approach to managing renal bleeding, preserving renal function.
