Dr Lakshmi Ratnam

Consultant Diagnostic and Interventional Radiologist


I am a Consultant Diagnostic and Interventional Radiologist at St George's Hospital in London. I have been a consultant radiologist for nine years and trained at St George's Hospital. I also completed a full year of additional specialist Interventional Radiology fellowship at the Charles Gardiner Hospital in Perth, Australia.

My particular areas of interest are uterine artery embolisation, pelvic congestion syndrome, the management of lymphovascular malformations with percutaneous sclerotherapy, salivary gland interventions and paediatric interventional radiology. In addition, I am also experienced in a wide range of vascular and non-vascular interventions including biopsy and drainage, insertion of lines, portacaths, peripheral arterial angiography and angioplasty, venography, venoplasty, fistuloplasty, nephrostomy and ureteric stenting, percutaneous transhepatic cholangiography and biliary stenting, transjugular liver biopsy, insertion of feeding tubes (gastrostomy and gastrojejunostomy, nasogastric and nasojejunal tubes), all of which I perform routinely in my practice.

I am currently the Head of Department for the Department of Radiology at St George's Hospital. Prior to this I was deputy head of department and clinical governance lead for the department as well as co-chair of the Hospital Thrombosis Group. I was also previously the Regional Educational Adviser for South Thames for the Royal College of Radiologists (April 2014 - January 2017).

I am a member of the Interventional Radiology Subcommittee for the European Congress of Radiology, a member of the Scientific Programme committee for the British Society of Interventional Radiology, as well as a member of the Editorial Board for Cardiovascular and Interventional Radiology Endovascular. I regularly lecture and present at local, national and international conferences on Interventional Radiology.

I am fully trained and qualified as a medical appraiser as well as an educational supervisor. I regularly supervise medical students and radiology trainees with projects and presentations. I have authored 12 articles in peer reviewed journals, written six book chapters, edited a book, and co-authored more than 40 posters and presentations at national and international conferences. I have delivered more than 20 invited lectures at national and international conferences.
