Open partial nephrectomy for pediatric renovascular hypertension.

Area of Science:

• Pediatric Nephrology
• Vascular Surgery
• Interventional Cardiology

Background:

• Pediatric renovascular hypertension often requires invasive interventions like revascularization or nephrectomy.
• Medically refractory cases present significant management challenges in children.

Observation:

• A 13-year-old boy with severe renovascular hypertension had failed prior arterial bypass surgery.
• Angiography and segmental renal vein renin sampling identified isolated hypoperfusion in the lower pole of the kidney.

Findings:

• An open partial nephrectomy successfully excised the hypoperfused renal segment.
• The patient achieved normotension off all antihypertensive medications post-surgery.
• No complications were noted 8 months after the procedure.

Implications:

• Partial nephrectomy is a viable therapeutic option for pediatric renovascular hypertension caused by segmental hypoperfusion.
• This organ-sparing technique should be considered in select pediatric cases to maximize renal function preservation.
