Summary
Congenital kidney arteriovenous malformations (AVMs) are rare. Transcatheter renal arterial embolization effectively treated two cases, resolving symptoms and showing minimal long-term renal impact.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Pediatric Urology
Background:
- Congenital arteriovenous malformation (AVM) of the kidney is a rare vascular anomaly.
- Rupture can lead to significant clinical manifestations including hematuria and flank pain.
Observation:
- Two pediatric cases of congenital renal AVMs presented with symptoms attributed to AVM rupture.
- Clinical presentation included hematuria, flank pain, and urinary retention secondary to clot formation.
Findings:
- Both cases were successfully treated with transcatheter renal arterial embolization.
- Post-embolization, patients experienced complete resolution of presenting signs and symptoms.
- Follow-up DMSA scans indicated focal loss of renal cortical function, suggesting localized impact without significant overall renal compromise.
Implications:
- Transcatheter embolization is a viable and effective treatment for congenital renal AVMs.
- Early intervention can prevent severe complications and preserve renal function.
- This approach offers a minimally invasive option for managing this rare condition.

01:25Hemodialysis I: Introduction
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...
01:19Imaging Studies VII: Vascular Imaging
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...
