FIG. 12.30 Occluded Celiac and Superior Mesenteric
Arteries. (A) Angiogram shows wide patency of origin
of the large, stented inferior mesenteric artery (IMA).
(B) Duplex Doppler at origin of IMA shows elevation of
systolic and diastolic velocity. (C) Duplex Doppler 3 cm
distal to IMA origin shows very similar elevation of velocity.
The velocity elevation was probably due to increased low
carried by the IMA to supply organs that are usually supplied
by the celiac and superior mesenteric arteries.

FIG. 12.31 Inferior Vena Cava (IVC) Anomalies. (A) Computed tomography image of duplicated IVC (black arrows), the most common anomaly
of the IVC. The left IVC joined the left renal vein. The IVC above the level of the renal veins was in the normal location. (B) Ultrasound of another
IVC anomaly, a left IVC running to the left of the aorta (Ao). The left IVC joins the left renal vein.
