Pediatric Interventional Radiology
Children are not small adults. The same catheters and needles behave differently in a 6 kg infant, radiation dose matters over a whole lifetime rather than a decade, and almost every case needs a paediatric anaesthetic team alongside the interventional one. Pediatric interventional radiology is the subspecialty built around that difference — treating renovascular hypertension, vascular anomalies, hepatic disease and long-term access problems through a needle or a catheter, in the smallest patients, at Cairo University's children's hospitals.

What it treats
- •Renal artery stenosis causing renovascular hypertension in children — treated by balloon angioplasty
- •Vascular anomalies: venous and lymphatic malformations, arteriovenous malformations and problem haemangiomas, treated by sclerotherapy or embolization
- •Long-term venous access — PICC lines, totally implanted ports, tunnelled and dialysis catheters placed under ultrasound and X-ray guidance
- •Hepatic intervention — liver biopsy including the transjugular route, biliary drainage, portal venous work and embolization of liver tumours
- •Image-guided biopsy of masses and organs where an open surgical biopsy would otherwise be needed
- •Drainage of abscesses and fluid collections, nephrostomy and urinary drainage, and gastrostomy feeding tubes
Who is a candidate?
- Children referred by paediatric nephrology, oncology, haematology, hepatology, surgery or the neonatal unit
- Infants and children needing reliable venous access for chemotherapy, prolonged antibiotics or intravenous feeding
- Children with hypertension shown to be renovascular on Doppler, CT or MR angiography
- Children with a vascular anomaly causing pain, bleeding, disfigurement or pressure on a nearby structure
- Neurointervention — anything inside the brain or spine — is outside this service and is referred to a dedicated neurointerventional team
How the procedure works
- 1
Joint assessment
The referring paediatric team, the anaesthetist and the interventional radiologist review the imaging together and agree whether an image-guided option is genuinely better than the surgical one for this particular child.
- 2
Anaesthesia
Most children need general anaesthesia rather than sedation — not because the procedure is bigger, but because a child cannot be expected to stay still. Fasting times, weight-based drug doses and airway planning are all set by the paediatric anaesthetic team.
- 3
Dose-limited guidance
Ultrasound is used wherever it can replace X-ray, and when fluoroscopy is needed it runs at paediatric settings — pulsed, collimated and stored rather than repeated. Contrast is calculated by weight.
- 4
The intervention
Access is through a fine needle sized to the child, and the balloon, sclerosant, embolic agent, catheter or drain is chosen for the vessel or cavity actually present rather than the adult equivalent.
- 5
Recovery with the paediatric team
The child recovers on the paediatric ward with their own team, and the interventional plan — what was done, what to watch for, when to review — is handed over in writing.
Recovery
Most children go home the same day or after one night, and the puncture leaves a mark rather than a scar. Expect a quiet 24 hours, a normal appetite by the next day, and school within a few days for the smaller procedures. Angioplasty and sclerotherapy need planned follow-up — blood pressure and Doppler after renal angioplasty, and repeat sessions for most vascular malformations, which are controlled over several treatments rather than cured in one. Parents are given the warning signs to act on and a direct route back to the team.
Discuss this procedure
Pediatric interventional radiology is delivered at Abu El Reesh, the Cairo University children's hospital (Monday, 10:00 AM – 12:00 PM) — a university service reached through the hospital's own outpatient system or a referral from your child's paediatric team, not by private booking. Referring physicians can use the Physician Hub. For private adult consultations, Andalusia Hospitals, Maadi.
Frequently asked questions
Is the radiation dose safe for a child?
It is the question worth asking, and it is the one this subspecialty is organised around. A child has more years ahead in which a dose could matter, so ultrasound replaces X-ray wherever it can, fluoroscopy runs at paediatric pulse and collimation settings, and the last image is stored rather than a new one taken. The dose from a modern paediatric interventional procedure is a fraction of what the same case would have cost a decade ago — and is weighed against the alternative, which is usually open surgery under a longer anaesthetic.
Will my child be awake?
Usually not. Most children have a general anaesthetic given by a paediatric anaesthetist, because staying perfectly still for the imaging is not something a child can reasonably be asked to do. That is planned in advance with fasting instructions and weight-based dosing, and the anaesthetist meets you before the procedure.
Do vascular malformations come back after treatment?
Venous and lymphatic malformations are controlled rather than cured. They are treated over a planned series of sclerotherapy sessions, and a proportion re-expand over years and need a further session — which is normal and expected, not a failure. Arteriovenous malformations are more demanding again. What treatment reliably does is control pain, bleeding, swelling and pressure on nearby structures.
Do you treat brain or spine conditions in children?
No. Neurointervention — aneurysms, brain and spinal vascular malformations, stroke intervention — is a separate subspecialty and is not part of this service. Those children are referred to a dedicated neurointerventional team. Everything else described on this page is done here.
