Summary
Renal arteriovenous fistula (RAVF), a rare vascular issue, can be effectively treated with minimally invasive endovascular embolization. This approach preserves kidney function and avoids surgery for complex cases.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Nephrology
Background:
- Renal arteriovenous fistula (RAVF) is a rare vascular anomaly connecting renal artery and vein.
- RAVF can cause hypertension, cardiac strain, renal impairment, and hematuria.
- Diagnosis relies on imaging like DSA, Doppler ultrasound, and CT.

2.1K
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
