IWR-PPP EP , IWR - PVP , fEVC

Question 20

Left gential vein anatomy

Answer 20

anterior to l external iliac vein, ascends between the inferior mesenteric vein and the ureter, and ultimately drains into the left renal vein.

Question 20

Predictor in hospital heart failure post STEMi (not LVEF)

Answer 20

Global Radial Strain

Ultrasound imaging the left genital vein crosses the iliac vein. consisting of the genital vein, iliac artery, and iliac vein

Question 22

Is the genital vein a single vein

Answer 22

no. it may be 2 or three so therefore it is technically a plexus

Question 34

Saturday night palsy imaging

Answer 34

thickening and a loss of its typical fascicular pattern without any discontinuity. This thickening is most pronounced in the region of the Spinal groove, where the nerve is compressed against the bone
