T. Akahane et al., CHANGES IN LIVER-FUNCTION PARAMETERS AFTER OCCLUSION OF GASTRORENAL SHUNTS WITH BALLOON-OCCLUDED RETROGRADE TRANSVENOUS OBLITERATION, The American journal of gastroenterology, 92(6), 1997, pp. 1026-1030
Objective and Methods: To evaluate the effects of portal blood flow on
liver function, this pilot study investigated the correlation between
changes in portal blood flow as measured by image-directed Doppler ul
trasonography and liver function tests in nine patients with cirrhosis
who were treated with balloon-occluded retrograde transvenous obliter
ation, All patients had large gastric varices and prominent gastrorena
l shunts, Results: Treatment caused a significant increase (p < 0.01)
in portal blood flow; we documented reversion from hepatofugal to hepa
topetal portal flow in one patient and increases in hepatopetal flow f
rom 5.4 +/- 1.1 to 7.85 +/- 1.4 cm/s (mean +/- SD) in eight patients.
All patients showed decreases in gastric variceal size, However, porta
l pressure rose significantly in all patients after treatment from 25.
4 +/- 7.6 to 30.7 +/- 5.8 mmH(2)O (n = 7, mean +/- SD), and two of nin
e patients had worsening of esophageal varices, All nine patients show
ed improvement in the 15-min retention rate of indocyanine green from
31.8 +/- 16.1 to 21.8 +/- 12.4% (mean +/- SD, p < 0.01), whereas seven
patients showed increased serum albumin levels after treatment, Concl
usions: These results suggest balloon-occluded retrograde transvenous
obliteration increases hepatic portal blood flow, which may be accompa
nied by improvements in liver function.
