From: Morphometric assessment of the left inferior phrenic vein in patients with portal hypertension
(a) Venogram of LIPV during BRTO. (b) The diameter of LIPV was measured at the midpoint between narrowing and the outlet of LIPV. The diameter of narrowed LIPV was measured at a narrow portion that was the closest to the outlet of LIPV. The distance to narrowed LIPV was defined as the distance from narrowed LIPV to the midpoint (= a) + the distance from the midpoint to the outlet of LIPV (= b). IVC, inferior vena cava; LRV, left renal vein; LIPV, left inferior phrenic vein; LARV, left adrenal vein; DN, Diameter of narrowed LIPV; DLIPV, Diameter of the left inferior phrenic vein.
