Imaging and interpretation

Vascular Ultrasound

Christchurch Vascular Group employs dedicated vascular scientists who are highly trained experts in the imaging of blood vessels. Vascular ultrasound is also available to the community for direct GP referral for investigation of vascular disease (DVT, Aorta, PAD, ABPI, Vein mapping, Treadmill or bike exercise testing). Vascular ultrasound is commonly used to assess blood flow, vein reflux, artery narrowing, aneurysm size, and bypass or stent surveillance. Good imaging is most useful when it is paired with a clear clinical question.

Vascular ultrasound diagnostic screen and clinical notes

What ultrasound can help assess

Varicose veins, venous obstruction, and venous reflux (valve function).
Carotid, aortic, peripheral artery, and graft surveillance.
Blood flow patterns, blood velocity changes, and swelling due to vascular problems.
Follow-up after vascular procedures where ultrasound is suitable.
Exercise stress tests for endofibrosis.
Ankle-Brachial Pressure Index (ABPI).
Acute or chronic thrombosis.
Ovarian vein reflux.
Renal vein blood flow.
Direct access is available for GP referrals.

Other imaging

CT angiography, MR angiography, and catheter angiography may be used when more detail is needed for diagnosis or treatment planning. Imaging choices depend on kidney function, contrast safety, previous results, urgency, and the decision being considered.

Bringing previous scans

If you have undergone previous imaging procedures outside the South Island, bring the report and, where possible, arrange access to the original images. This can reduce duplication and make your consultation more useful.

Next step

Discuss a vascular enquiry

Share the clinical question, relevant history, and any previous imaging so the next step can be planned appropriately.
