Targeted puncture of left branch of intrahepatic portal vein in transjugular intrahepatic portosystemic shunt to reduce hepatic encephalopathy

Table 2 Portosystemic gradient changes in the two groups

Groups	PSG in mmHg		t value	P value
	Before	After
Group A	27.08 ± 5.47	10.75 ± 3.67	13.79	0.001
Group B	26.42 ± 3.53	10.96 ± 2.41	18.64	0.003
	(T value) 0.622	0.284
	(P value) 0.536	0.777

Both TIPS procedures demonstrated a similar efficacy in decreasing portosystemic gradient before and after TIPS placement. PSG: Portosystemic gradient; TIPS: transjugular intrahepatic portosystemic shunt.
