Pulsed wave Doppler in a normal portal vein. Using the sample volume the sonographer is able to define the studied volume, in this case it has a width of 4 mm.

Aliasing. The velocity overwhelms the máximum limit in the velocity profile (red-yellow), depicting the botom of the negative velocities (green-blue). However the blood dierction does not change.

Thrombosis of the caudal vena cava. A-B: In this dog with renal adenocarcinoma, there is an echogenic thrombus filling most of the venous (CVC) lumen in transverse (A) and longitudinal (B) planes. More caudally, it extends into the right renal vein that is markedly distorted by the malignant thrombus (T). K, right kidney; RA, right adrenal gland; Ao, aorta. C-E: In this other dog with adrenal adenocarcinoma, a thrombus (between cursors) is detected in the CVC. This thrombus is associated with contrast enhancement in dorsal SPGR MR image (D) and extends into an abnormal left adrenal (Ad). The transverse T2w MR image (E) shows the connection between the malignant thrombus (T) and the left adrenal (Ad) through the phrenicoabdominal vein, just ventral to the aorta (Ao).

B-mode ultrasound image. B-mode ultrasound image showing the portal vein (PV), of one dog. Diameter measurement between callipers (0.54 cm). Transverse section at the right 11th intercostals space.

Color Doppler mapping showing the origin of the right branch of the portal vein in one dog. Note that the axis of the vessel is very close to that of the ultrasound wave, which provides an optimal insonation angle, with the flow running towards the transducer. Longitudinal section at approximately the right 10th intercostal space (RBPV: right branch of portal vein; CVC: caudal vena cava; AA: abdominal aorta; PV: portal vein).

Spectral Doppler mapping of the right branch of the portal vein (RBPV) of one dog. Longitudinal section at approximately the right 10th intercostal space. Note the insonation angle (12 degrees), which provides measurements with minimum margin of error. The flow is monophasic and presents low pulsatility.
