Clinical experience
Mr Crinnion’s interest in vascular surgery developed during two years as a Research Fellow at Leeds General Infirmary and a year as Registrar at Ealing Hospital, London. He then completed three further years of vascular training at Northwick Park Hospital, St Mary’s Regional Vascular Unit and Chelsea and Westminster Hospital.
As a consultant he established a one-stop venous clinic and a local anaesthetic endovenous laser clinic, performing more than 500 laser procedures. He is trained in vascular ultrasound and runs a consultant-led one-stop vascular clinic, and has a special interest in preventing and managing foot complications associated with diabetes.
Mr Crinnion has provided an endocrine surgical service for many years, regularly performing thyroid and parathyroid operations. Almost all parathyroid procedures are performed via a targeted approach, using preoperative nuclear medicine and ultrasound imaging.
His clinical use of ultrasound allows the exact site of thyroid swellings to be identified immediately before surgery, so the incision can be placed appropriately. His department has presented at the British Association of Endocrine Surgeons and the Association of Surgeons of Great Britain and Ireland, and contributes to the national endocrine surgery audit.
Working at Whipps Cross, a busy acute district general hospital, has given Mr Crinnion extensive emergency surgical experience. His elective general surgical work includes laparoscopic cholecystectomy, hernia repair and soft tissue surgery.
He has developed his skills in minimally invasive surgery and regularly performs laparoscopic gallbladder and hernia operations.

He has a strong commitment to surgical training and has had a specialist registrar assigned to his firm for many years.
Write-ups
Mr Crinnion’s research has focused on vascular surgery, and in particular the injury to skeletal muscle that follows limb ischaemia and reperfusion. As a consultant he has been senior author on several papers and has presented at the Vascular Surgical Society of Great Britain and Ireland and the British Association of Endocrine Surgeons.
The role of neutrophils in the pathogenesis of skeletal muscle injury following limb ischaemia and reperfusion.
A period of full-time laboratory research at the University of Bradford investigating the cause of the muscle injury and limb swelling that follows lower limb ischaemia. The work showed that some of the post-ischaemic injury was mediated by neutrophils and could be reduced by inhibiting neutrophil function. Part of this work was awarded the British Journal of Surgery Prize.
