Alex Barnacle - Radiology team
Dr Alex Barnacle is a Consultant Paediatric Interventional Radiologist and has worked at Great Ormond Street Hospital for Children (GOSH) since 2003.

"I specialise in interventional radiology, which involves image-guided keyhole surgery and other minimally-invasive procedures which are used to diagnose or treat a wide variety of conditions in children. I have a special interest in working with children who have complex birthmarks or vascular malformations. I also work closely with the urology team in treating children with kidney stones."

The diagnosis and treatment of:

  • vascular anomalies, especially vascular malformations such as high flow arteriovenous malformations (AVMs)

  • lymphatic malformations and venous malformations

  • minimally invasive keyhole procedures for treating kidney stones in children



Dr Barnacle undertook her undergraduate medical training at the University of Southampton. After a variety of specialist posts in paediatric medicine, neonatal intensive care and paediatric surgery on the south coast and in London, she completed training in radiology at Charing Cross and Hammersmith Hospitals in London. This included an 18 month fellowship in paediatric radiology and interventional radiology at Great Ormond Street Hospital, London, followed by a 12-month fellowship in paediatric radiology at the Royal Children’s Hospital in Melbourne, Australia.

She was appointed as a consultant in interventional radiology at GOSH in 2004.

She is the lead radiologist in the Vascular Anomalies Service at GOSH with a special interest in children with complex malformations.

She is the lead interventional radiologist in the team of doctors who manage children with kidney stone disease at GOSH, providing keyhole surgical techniques (PCNL and PCCL) for stone removal.

She is a member of:

  • Society of Pediatric Interventional Radiology (SPIR)

  • International Society for the Study of Vascular Anomalies (ISSVA)

  • British Society of Interventional Radiology (BSIR)

  • Cardiovascular and Interventional Radiology Society of Europe (CIRSE)

  • European Society of Paediatric Radiology (ESPR)

She is the co-director of the bi-annual UK conference ‘Vascular Anomalies: A clinical approach’.

Research Interests

Research interests include the diagnosis and management of vascular anomalies, with particular current research interest into the management of orbital malformations.

Other interests cover a wide spectrum of paediatric interventional radiology procedures, developing new techniques and modifying adult procedures for use in children, as this is a new and rapidly evolving field of medicine.
