Hepatic Intervention in Children
Children's liver disease brings problems that suit a catheter better than an operation: tissue is needed for a diagnosis but clotting is deranged, bile is obstructed after a previous repair, the portal vein has narrowed after a transplant, or a tumour needs shrinking before surgery. Each of these can be reached through a needle or a catheter under imaging, in a child who is often already fragile, and without an anaesthetic longer than the problem warrants. This work is done alongside paediatric hepatology, oncology and the transplant surgeons rather than instead of them.

What it treats
- •Liver biopsy for diagnosis, staging or graft assessment — percutaneously, or by the transjugular route when clotting is deranged or ascites is present
- •Blocked or leaking bile ducts, including after a Kasai procedure or a liver transplant, drained and then dilated or stented
- •Narrowing or clot in the portal vein, including after transplant, and portal pressure measurement
- •Liver tumours in children — chemoembolization to shrink a tumour before surgery, or to control one that cannot be removed
- •Drainage of collections, abscesses and bile leaks after liver surgery or transplant
- •Hepatic artery narrowing after transplant, threatening the graft
Who is a candidate?
- Children under paediatric hepatology, oncology or a transplant service where imaging has shown a treatable problem
- Children needing liver tissue in whom clotting or ascites makes a percutaneous biopsy unsafe — the transjugular route exists for exactly this
- Children with jaundice, cholangitis or a bile leak that endoscopy cannot reach or has failed to solve
- Children with a liver tumour being assessed for surgery, where the plan is agreed at a multidisciplinary meeting first
- Clotting, platelets and any active infection are reviewed and corrected before anything is done
How the procedure works
- 1
Multidisciplinary planning
The imaging, the bloods and the question being asked are reviewed with the hepatology, oncology or transplant team, so the right target and the right route are chosen before the child is anaesthetised.
- 2
Anaesthesia and correction
Children have a general anaesthetic. Clotting factors, platelets or antibiotics are given first where needed — much of the safety of this work happens before the needle.
- 3
Access
For biopsy and drainage, a fine needle is placed under ultrasound, with CT for deeper or smaller targets. For vascular or biliary work, a catheter is navigated from a vein at the neck or groin, or a duct is punctured directly under ultrasound and X-ray.
- 4
The intervention
Tissue is taken, a drain is left over a wire and connected to a bag, a narrowing is dilated with a balloon, or an embolic and chemotherapy agent is delivered into the vessels feeding a tumour — sized and dosed for the child.
- 5
Documentation and handover
The result is confirmed on imaging, and the plan — drain care, when it comes out, when to review, what to watch for — is handed back to the paediatric team in writing.
Recovery
After a biopsy, children rest in bed for several hours with observation and usually go home the next day; some discomfort at the puncture and in the right shoulder is normal. A biliary drain stays connected to a bag and needs a simple daily routine that the ward team teaches, and it is reviewed and often exchanged or removed at a planned session rather than left indefinitely. After tumour embolization expect a few days of fever, nausea and aching as the treated tissue breaks down, managed on the ward. Follow-up imaging is arranged in every case, because in this work the check is part of the treatment.

Frequently asked questions
Why a transjugular biopsy rather than through the skin?
Because it stays inside the vein. When clotting is deranged or there is fluid in the abdomen, a needle passed through the liver capsule from outside can bleed into the abdomen. The transjugular route reaches the liver from a vein in the neck, so any bleeding returns to the vein rather than escaping — and it allows the portal pressure to be measured at the same time.
How long will a biliary drain stay in?
Long enough to settle the infection or the leak and to let the duct be treated — usually weeks rather than days, sometimes longer when the narrowing needs repeated dilatation. It is reviewed at planned sessions with the aim of internalising or removing it, not leaving it in place indefinitely.
Does chemoembolization replace surgery for a liver tumour?
Usually not — most often it is used to shrink a tumour so that surgery becomes possible, or to control one where surgery is not an option. Which role it plays in your child's case is decided at a multidisciplinary meeting with the oncology and surgical teams, and that decision is explained to you before anything is booked.
Is it safe in a child who is already very unwell?
That is often precisely why it is chosen. Draining an obstructed duct or taking a biopsy through a catheter asks far less of a sick child than an operation under a long anaesthetic. The risks are real and are discussed specifically — bleeding, infection, and the exposures involved — and are weighed against leaving the problem untreated.
