Mr Vat Vathanan, Consultant Gynaecologist for gynaecology and early pregnancy care in Windsor, Ascot, Slough, Maidenhead, Bracknell, Gerrarda€?s Cross and Berkshire

After completing his postgraduate training (MS a€“Master of Surgery) in Obstetrics and Gynaecology from Sri Lanka, Vat moved to United Kingdom in 2004 to pursue his advanced training. He continued his training in Yorkshire and London. He completed his Specialty training in London Deanery and was awarded the Certificate of Completion of Training (CCT) in 2011. During the last 3 years of training he underwent advanced skills training in laparoscopic surgery, emergency gynaecology and early pregnancy at Queen Charlottea€?s Hospital, London, at Chelsea and Westminster Hospital, London and at Northwick Park Hospital, Harrow. He continued his advanced training in minimal access surgery and endometriosis as a post CCT fellow at The Chelsea and Westminster Hospital and its Endometriosis Centre, London. After completing basic and intermediate training in ultrasound scanning, he also underwent advanced training in Queen Charlotte Hospital and Kinga€?s College London and obtained Post Graduate diploma in Medical Ultrasound (Gynaecology and Early Pregnancy) with Merit from Kinga€?s College London. He was appointed as Consultant Obstetrician and Gynaecologist at Wexham Park and Heatherwood Hospitals (currently Frimley Health NHS) in 2012. Currently he is the Lead for Early pregnancy services at the hospital.

He has extensive experience in all benign gynaecology conditions including menstrual disorders, endometriosis, chronic pelvic pain, fibroid, ovarian cysts and uterovaginal prolapse. He has particular interest in early pregnancy and minimal access surgery including endometriosis and reproductive surgery. He runs regular general gynaecology, early pregnancy and dedicated recurrent miscarriage clinics in the Trust. Through his advanced training, he aims to perform most of the surgeries via laparoscopy (key hole surgery) including hysterectomy, ovarian cyst removal, fibroid removal, ectopic pregnancy and endometriosis. This approach helps his patients to have major surgeries with minimal scars in the tummy (usually 2 or 3 scars of 5 to 10 mm in size) with early recovery and early return to work. His extensive experience in ultrasound scanning helps him to diagnose gynaecology and early pregnancy conditions with confidence. He also performs 3D ultrasound scans for investigations in particular to diagnose uterine (womb) anomalies.
