Otago Diagnostics LogoWe are a team of vascular surgeons, technologists and research staff using various diagnostic investigations to research the causes and management of vascular conditions.

Clinical services

Female sonographer performing an ultrasound carotid scanThe unit provides clinical diagnostic services to the Southern District Health Board, and to the wider community, to assist in the diagnosis and treatment of vascular diseases such as:

  • Deep vein thrombosis
  • Carotid artery disease
  • Peripheral vascular disease
  • Aortic aneurysms
  • Varicose veins and venous ulcer

Our services include:

  • Medical imaging using ultrasound to capture real-time images of blood vessels and blood flow
  • Physiological testing to measure how well the vascular system is functioning both during exercise and at rest
  • Treatment of varicose veins and vascular malformations using endovenous laser therapy (EVLT) and sclerotherapy


Male sonographer performing ultrasound scan of legThe unit is part of the Vascular Research Group and works closely with other research groups at local, national and international levels.

Many patients participate in a wide variety of research projects, enabling the unit to make valuable contributions to the field of vascular research.

Information about the Vascular Research Group


Otago Vascular Diagnostics is a teaching laboratory active in training vascular technologists.

Trainees work under supervision while studying for the Diploma of Medical Ultrasonography (DMU). This is an internationally recognised qualification in diagnostic ultrasound awarded by the Australasian Society for Ultrasound in Medicine (ASUM).
