Doppler ultrasound technique, territory by territory

Practical scanning protocols for vascular Doppler ultrasound: equipment, patient positioning, the systematic sequence of assessment, dynamic manoeuvres and the parameters to measure. For diagnostic criteria and reporting thresholds see the guidelines; for how to use the application see the step-by-step guide.

Carotid and vertebral arteries

Carotid and vertebral arteries Common carotid, bulb, internal and external carotid, vertebral arteries. Distinguishing ICA from ECA, and looking for subclavian steal.

Upper limbs

Upper limb arterial Subclavian, axillary, brachial, radial and ulnar arteries. Thoracic outlet manoeuvres, Allen test. Upper limb venous Jugular, subclavian, axillary, brachial, basilic and cephalic veins. Catheter-related thrombosis, Paget-Schroetter syndrome.

Lower limbs

Lower limb arterial Iliac, femoral, popliteal and calf vessels. Flow profile, velocity criteria for stenosis, aneurysms. Lower limb venous Deep system (compression) and superficial system (reflux on Valsalva and calf squeeze). CEAP classification.

Abdomen and retroperitoneum

Abdominal arterial Aorta, iliac arteries, coeliac axis, superior mesenteric artery. Patient preparation, aneurysm screening. Renal arteries Direct assessment of the origin, renal-aortic ratio, intrarenal Doppler, parvus-tardus pattern.

Vascular access

Arteriovenous fistula (AVF) Surveillance of the dialysis access, volume flow measurement (Qa), stenosis criteria, steal syndrome, maturation.
Note These protocols describe the scanning technique and are addressed to whoever actually performs the examination. Diagnostic thresholds and reporting criteria (degree of stenosis, clinical classifications) are collected separately in the reporting guidelines.
