Abnormal splenic artery diameter/hepatic artery diameter ratio in cirrhosis-induced portal hypertension

Table 3 Comparisons of preoperative and postoperative portal vein hemodynamic indexes in patients with cirrhosis and portal hypertension who received splenectomy (n = 17)

Variables	Before splenectomy	After splenectomy	P value
Portal vein
Pressure (cm H2O)	39.19 ± 5.87	27.04 ± 3.03	< 0.0011
Flow rate (mL/min)	1005.50 (833.00-1811.25)	868.00 (539.50-1215.75)	0.116
Maximum flow velocity (cm/s)	23.85 (18.53-31.20)	15.85 (12.68-20.58)	0.0091
Mean flow velocity (cm/s)	20.85 (15.90-25.95)	12.25 (10.48-16.40)	0.0111
Hepatic artery
Flow rate (mL/min)	153.50 (128.75-188.77)	365.00 (190.00-511.00)	0.0481
Minimum flow velocity (cm/s)	16.25 ± 15.23	32.60 ± 15.23	0.0011
Resistance index	0.74 ± 0.05	0.64 ± 0.07	< 0.0011

¹Indicates significant difference between preoperative and postoperative values. Data were presented as mean ± SD, or median (interquartile range: Q1-Q3) if not normally distributed. Preoperative and postoperative data were compared using paired t-test or Wilcoxon sign-rank test if data were not normally distributed.
