Article Abstract
Background And Aims: Transjugular intrahepatic portosystemic shunt (TIPS) allows a high blood volume into systemic circulation abruptly. The primary aim of the study was to investigate the effect of TIPS on systemic, portal hemodynamics, and electric cardiometry (EC) parameters in sedated and spontaneous breathing patients. Secondary aims??
Material And Methods: Adult consecutive hepatic patients scheduled for elective TIPS were included. Patients were sedated with bispectral index-guided propofol infusion + fentanyl boluses. EC parameters, i.e., cardiac output (CO) and systemic vascular resistance (SVR) were noted. Noninvasive blood pressure, heart rate, central venous pressure (CVP, cmHO), and portal venous pressure (PVP, cmHO) were measured pre- and post-TIPS.
Results: Thirty-six people were enrolled ( = 25 included) from Aug 2018 to Dec 2019. Data (expressed in median (IQ)) were: age 33 (27-40) years, body mass index 24 (22.0-27) kg/m, child A 60%, B 36%, and C 4%. Post-TIPS, PVP decreased (from 40 [37-45] to 34 [27-37] mmHg, < 0.001), whereas CVP increased (from 7 [4-10] to 16 [10.0-19.0] mmHg, < 0.001). The CO increased ( = 0.03) and SVR reduced ( = 0.012).
Conclusion: The reduction in PVP following successful TIPS insertion elevated the CVP abruptly. EC was able to monitor an immediate increase in the CO and a reduction in SVR in association with the above PVP and CVP changes. The results of this unique study indicate that EC monitoring is promising; however, further evaluation in a larger population and in correlation with other gold-standard CO monitors is still indicated.

We report the case of a 70-year-old woman with advanced hepatic encephalopathy (HE) secondary to metabolic dysfunction-associated steatohepatitis (MASH)-related cirrhosis who exhibited an excellent response to portosystemic shunt embolization. Four years earlier, she was diagnosed as having MASH-related cirrhosis accompanied by multiple mesenteric vein-inferior vena cava shunts. As her condition progressed, she suffered recurrent HE that was unresponsive to oral medication, prompting the decision to proceed with shunt embolization.

Background: Three patients with portal hypertension and gastrointestinal bleeding due to non-cirrhotic portal vein thrombosis were treated with portal venous recanalization transjugular intrahepatic portosystemic shunt (PVR-TIPS) via a trans-splenic access.
Main Body: A "bottoms-up" retrograde puncture of the right hepatic vein was performed using a re-entry catheter to gain access to the right hepatic vein. In all patients a successful retrograde puncture of the right hepatic vein was achieved, thereby restoring the splenoportal tract.

Purpose: To evaluate the consistency and agreement between portal venous pressure measured by fine-needle (F), portal vein catheterization (D), and hepatic vein balloon-occlusion (W) in decompensated cirrhotic patients with intrahepatic venovenous shunts (IHVS).
Materials And Methods: 156 consecutive patients planning to receive transjugular intrahepatic portosystemic shunt in our center were screened for study participation. The F/D/W were assessed for consistency by Pearson coefficient (r), linear regression coefficient (R), and intraclass correlation coefficient (ICC), and for disagreement (error exceeding 20% of D) by Bland-Altman method.
