Having qualified in 1984 and completing his pre-registration training in the Republic of South Africa, Mark Tyrrell moved to the UK in 1986.
He trained in general surgery with a special interest in vascular surgery in London and the south east. This included a PhD and DIC obtained during a period of research at St. Mary's/Imperial College London, as well as passing the fellowship examinations for the Royal College of Surgeons of England and of Edinburgh.
He took up his first consultant appointment as a vascular and general surgeon in Royal Tunbridge Wells in April 1996, where he established and ran a successful single-handed specialist vascular unit offering the full range of open arterial and venous surgery in the setting of a district general hospital.
Due to NHS reorganisation, Mark moved to the King's College Hospital vascular unit in August 2006, where he became clinical lead for vascular surgery and developed the aortic endovascular program. International collaboration aided the rapid evolution of this program to include the most modern complex endovascular aortic procedures.
Mark saw an opportunity for the furtherment of vascular services in south east London by the merger of the departments of King's College Hospital and Guy's and St Thomas'. He chaired the relevant business case committee and oversaw the initial stages of the merger, effectively transferring his inpatient activity from King's to St Thomas' Hospital in July 2012.
At present, Mark provides outpatient (including vascular lab) and day surgery services on an outreach basis in Tunbridge Wells - and inpatient services (for patients from Tunbridge Wells as well as the local catchment area) at St Thomas'. Day surgery in the Pembury hospital comprises varicose vein operations and minor amputations. In patient surgery in the Guy's and St Thomas' NHS Trust comprises the full range of open and endovascular arterial surgery and a sub-specialty in spinal exposure for anterior spinal surgery in collaboration with that specialist team. Mark has particular interests in complex aortic (open and endovascular) and carotid surgery.
In addition, Mark has run a small private practice at the Nuffield hospital, Tunbridge Wells for over 20 years. All types of consultation, including Duplex scanning are undertaken. The majority of surgery relates to the management of peripheral venous hypertension (most commonly expressed as varicose veins), for which he offers the full range of open and endovenous treatment options. More complex private surgery is undertaken either in the private suite at St Thomas' hospital or at the Nuffield, depending on equipment required and patient frailty.
