Post-biopsy intrarenal arteriovenous fistula
The Journal of Urology
|August 1, 1979
Summary
Intrarenal arteriovenous fistulas can occur after renal biopsy procedures. Prompt intervention, including nephrectomy, may be required to manage complications like severe hypertension and hematuria.
Area of Science:
- Nephrology
- Urology
- Interventional Radiology
Background:
- Renal biopsy is a common diagnostic procedure.
- Arteriovenous fistulas are abnormal connections between arteries and veins.
- Complications following renal biopsy require careful management.
Observation:
- Five cases of intrarenal arteriovenous fistulas (AVFs) post-renal biopsy were identified.
- Three AVFs occurred after percutaneous needle biopsy.
- Two AVFs occurred after open renal biopsy.
Findings:
- One patient underwent nephrectomy for severe hypertension secondary to a hydronephrotic kidney.
- Another patient required partial nephrectomy to manage significant hematuria.
- These cases highlight potential vascular complications of renal biopsy.
Implications:
- Early recognition and management of post-biopsy AVFs are crucial.
- Interventional techniques may be necessary to control bleeding and preserve renal function.
- Understanding these risks can inform procedural improvements and patient counseling.
