Carotid stenosis — velocity criteria?

Per SRU (Society of Radiologists in Ultrasound, 2003), stenosis 230 cm/s. Confirm with ICA/CCA ratio and residual diameter.

DVT — when to repeat a negative study?

With high clinical probability and negative US, consider repeat in 5–7 days or CT angiography. With low probability and negative D-dimer, DVT is generally excluded without repeat.

Superficial venous reflux — threshold?

Reflux time > 0.5 s in superficial veins (GSV/SSV, tributaries) and > 1.0 s in deep veins, with Valsalva or distal compression.

Report template — Ultrasound of Doppler rim transplantado

When to use

Vascular Doppler evaluates patency, direction and velocity of arterial and venous flow. Indicated for suspected DVT, venous insufficiency, peripheral arterial disease, carotid stenosis and post-revascularization follow-up.

What to evaluate

Segmental venous compressibility (DVT — loss of compressibility).
Venous waveform: respiratory phasicity, distal augmentation.
Arterial spectral Doppler: morphology, peak systolic, indices.
Venous reflux > 0.5 s (superficial) or > 1.0 s (deep).
Stenoses: velocity ratio, jet and plaque morphology.

- Rim transplantado: na fossa ilíaca direita esquerda, com dimensões normais ( cm). Espessura e ecogenicidade parenquimatosas preservadas. Ausência de hidronefrose ou cálculos detectáveis. - Peritôneo e retroperitôneo: não há coleções significativas junto ao enxerto. Ao estudo Doppler: - Anastomose arterial: prévia, com velocidades sistólicas dentro dos limites da normalidade. - Artérias intrarrenais: com índices de resistência (IR) variando entre 0,X e 0,X. - Anastomose venosa: pérvia, sem aumentos significativos de velocidade. Conclusão: - Ultrassonografia com Doppler do rim transplantado sem alterações significativas.
