Professional profile

Vascular Surgery
Mr Crinnion has been a Consultant Vascular & General Surgeon at Whipps Cross University Hospital and Royal London Hospital since 1999. At Whipps Cross he established an endovascular aneurysm repair (EVAR) service with the interventional radiologists, a one-stop venous clinic and a local anaesthetic endovenous laser clinic. He has developed a special interest in the management and prevention of the foot complications associated with diabetes in which he liaises closely with the Endocrinologists and Specialist Podiatrist.

Mr Crinnion has been trained in vascular ultrasound and now runs a consultant led “one stop vascular clinic” which has significantly streamlined the service. Since 2011 Mr Crinnion is a member of the vascular surgical team at the Royal London Hospital treating patients with complex vascular conditions.

In his private practice Mr Crinnion specialises in the cosmetic treatment of varicose veins and venous flares using endovenous laser ablation (EVLT) and Sclerotherapy and this is a service he provides at OSD Healthcare.

Endocrine Surgery
For the last 20 years Mr Crinnion has provided an endocrine surgical service performing between 50-70 thyroid/parathyroid procedures annually. He now performs almost all of the parathyroid procedures via a targeted approach using preoperative ultrasound imaging.

General Surgery
Mr Crinnion has obtained extensive emergency surgical experiences since working at Whipps Cross. In addition to endocrine surgery his elective general surgical work includes laparoscopic cholecystectomy, open and laparoscopic inguinal hernia repair, and soft tissue surgery. He has a particular interest in the treatment of inguinal hernia.
