The sonographer's use of spectral Doppler in the common femoral vein for the assessment of iliac vein obstructions: A retrospective audit

Abstract

Iliac vein obstructions account for 2%–3% of all lower limb deep vein thromboses (DVT). Delayed diagnosis can lead to a higher risk of limb ischemia in the acute setting and post‐thrombotic syndrome in the chronic setting. The purpose of this audit was to determine whether sonographers were taking and interpreting waveforms correctly at the common femoral vein (CFV).
