Left Gastric Arterialgraphy (LGA) before and after sclerotherapy for esophageal varices was studied in 32 cases, in comparison with Endoscopic Varicearography during Injection Sclerotherapy (EVIS). Visualization rate of esophageal varieces in LGA was 90.6%. Directions of blood flow showed three ways; in LGA:1) hepatofugal, 2) hepatopetal, and 3) bidirectional, showing 53.1%, 3.1% and 43.1%, in each direction respectively.<BR>On the other hand, in directions of blood flow in EVIS, 1) hepatofugal, and 2) bidirectional accounted for 68.8% and 31.2% respectively. Corresponding ratio between LGA and EVIS was 50%. Improvement in direction of blood flow was recognized in 93.8% of the cases by repeating LGA. In comparison with LGA after sclerotherapy and the endoscopic findings, esophageal branch in LGA venous phase shows surphase vein and cardiac plexus shows extraluminal vein. Sudare vein suggested the change in site from extra-to intra-luminal occurred at around its mid-line. Feeding tract on EVIS participated in the left gastric vein in 80% of all cases, but other tract could not be negrected.
