Summary
Renal arteriovenous malformations (AVMs) are abnormal vascular connections. This case study shows open fistula ligation as an effective treatment for complex renal AVMs when embolization fails.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Nephrology
Background:
- Renal arteriovenous malformations (AVMs) represent abnormal connections between renal arteries and veins.
- Arteriovenous fistulas constitute 70%-80% of renal AVMs, frequently stemming from iatrogenic causes.
- While often asymptomatic, renal AVMs can present with hematuria due to rupture.
