Transjugular Intrahepatic Portosystemic Shunt for Preventing Rebleeding of Esophageal Varices in Patients with Portal...

Recurrent esophageal variceal bleeding and/or refractory ascites in patients with cavernous transformation of the portal vein (CTPV) is associated with a high fatality rate. Transjugular intrahepatic portosystemic shunt (TIPS) provides a treatment option for preventing esophageal variceal rebleeding and/or refractory ascites. This retrospective study evaluated the safety and efficacy of TIPS for the patients involved.

The records of 41 consecutive patients with CTPV who underwent TIPS at our institution from January 2015 to May 2019 were reviewed. Among the 41 patients, 36 patients had variceal rebleeding only, and 5 patients exhibited both variceal rebleeding and refractory ascites. Ten of these patients underwent TIPS via a transjugular pathway alone; a combined transjugular/transhepatic pathway and a combined transjugular/transsplenic pathway were adopted for 21 and 3 patients, respectively; and the remaining 7 patients failed TIPS.

TIPS succeeded in 34 of 41 (82.9%) patients. Four of 34 patients with CTPV were successfully cured with a thick collateral caval stent shunt operation. After TIPS, the mean portosystemic pressure gradient declined from 24.60 ± 6.15 mmHg to 15.89 ± 4.08 mmHg (P < 0.01). The occurrence rate of variceal rebleeding in the TIPS success group was lower than that in the TIPS failure group (11.8% vs 42.9%, P < 0.05). The occurrence rate of recurrent ascites in the TIPS failure group was greater than that in the TIPS success group (75% vs 15.8%, P < 0.05). TIPS patency was 76.5% (26 of 34 patients). During the follow-up time (median 12.64 months), the rate of hepatic encephalopathy was 5.9%, and the survival rate was 85.3%.

TIPS is an effective and safe alternative therapy for preventing esophageal variceal rebleeding and/or refractory ascites in patients who exhibit CTPV, and these findings may be beneficial to clinical research.
