Transjugular intrahepatic portosystemic shunt (TIPS or TIPSS) is a treatment for portal hypertension in which direct communication is formed between a hepatic vein and a branch of the portal vein, thus allowing some proportion of portal flow to bypass the liver.

In keeping with the classical surgical literature, primary patency is defined as the period from TIPS placement to shunt occlusion or the development of a significant stenosis However, the reported primary patency rates of ePTFE-covered stent at 2, 4, and 6 years were 74%, 62%, and 50% respectively [ 8, 9 ]. To manage TIPS dysfunction, several modalities of recanalizations were used including thrombolysis, thrombo-suction, balloon angioplasty, and in-stent insertion TIPS patency should be monitored at intervals using duplex Doppler US, which allows velocity measurements within the TIPS to be obtained noninvasively. Significant velocity increases from baseline may indicate the presence of TIPS stenosis, which may prompt TIPS venography and revision by balloon dilation or additional stent placement Following TIPS creation, patients underwent cross-sectional imaging at approximately 1-month post-procedure and then at 3-4 month interval to assess clot clearance and venous patency. After TIPS, Doppler ultrasound imaging performed at median 27 ± 79 (mean: 63) days post-procedure showed mean portal venous velocity increase from 13.5 ± 6.7.

TIPS were created with bare stents (n = 41) or stent-grafts (n = 40).

Our purpose is to compare the stent patency and clinical outcome of trans-jugular intra-hepatic porto-systemic shunt (TIPS) through the left branch portal vein (TIPS-LPV) to the standard TIPS through the right branch (TIPS-RPV). We retrospectively reviewed all patients (n = 54) with refractory portal hypertension who were subjected to TIPS-LPV at our institute (TIPS-LPV) between 2016 and 2018

The Role of Transjugular Intrahepatic Portosystemic Shunt (TIPS) in the Management of Portal Hyperten-sion is now posted online at www.aasld.org. This is the to maintain patency because of the use of bare stents. A cost analysis showed TIPS to be slightly more cost effec Overall TIPS patency rates were compared between these two groups, as were clinical outcomes in patients with variceal bleeding and those with ascites. Results: In the bare stent group, primary shunt patency rates were 63%, 48%, and 24% at 3, 6, and 12 months, respectively. Secondary patency rates were 75% and 62% at 3 and 6 months, respectively The improved patency has resulted in a clear reduction in recurrence of portal hypertension and also the number of reinterventions needed to improve TIPS patency. Additionally, covered stents offer a significant survival benefit Variceal bleeding is a severe complication of portal hypertension and a major cause of death in patients with cirrhosis.

By injecting a small volume (about 0.3 ml) of a radiotracer into the shunt reservoir, the flow of CSF through the catheters and valve can be measured. Learn more: Read our Shunt Patency.

Assisted shunt patency is better after TIPS. Treating medically refractory ascites with TIPS risks early shunt-related mortality for prospects of longer survival with ascites control. This study promotes the application of TIPS for medically intractable ascites if patients undergoing TIPS have prospects beyond short-term survival Neth J Med. 2020 Dec;78(6):333-340.ABSTRACTBACKGROUND AND AIMS: Transjugular intrahepatic portosystemic shunt (TIPS) is an effective intervention to treat complications of portal hypertension. Since the introduction of polytetrafluoroethylene (PTFE)-covered stents, TIPS patency rates have improved, and the need for routine TIPS surveillance has become questionable Primary unassisted patency (A), recurrent variceal bleeding (B) and recurrent ascites (C) in four groups of patients with transjugular intrahepatic portosystemic shunt.

A transjugular intrahepatic portosystemic shunt (TIPS) is a percutaneous method used to treat the complications of portal hypertension. During the TIPS procedure, a channel, which shunts blood from the portal vein to a hepatic vein, is created through the hepatic parenchyma, reducing the portosystemic pressure gradient. of shunt patency. Duplex ultrasound is sometimes used to assess the patency of TIPS. This study examined the accuracy of duplex ultrasound, with venography and direct portosystemic pressure measurements as the comparative gold standard. There were 60 assessments of TIPS in 38 patients, all done within 9 months of TIPS placement. Of 31 occlusions or.

The mean duration of the patency of the stent has to do with 12 months. The biliary stenting is performed either with plastic or metal stents, studies recommending their replacement. In the present study, the one-year cumulative patency rate was 86.7% and the two-year patency rate was 75.2% . These were slightly higher than the patency rate of the dedicated TIPS Viatorr stent reported previously and significantly higher than previously reported bare-metal stent patency rates (16-17). There was a significant difference.

There are many types of surgically placed feeding tubes, including both gastrostomy (G) and jejunostomy (J) tubes. Complications with these tubes are commonly seen in the emergency department and this article provides a general overview of these complications and how they can be quickly and easily managed by the emergency physician The main limitation is that the full cooperation of tested subjects is crucial for the validity of PNIF and POIF measurement, and PNIF increases with practice. Bottom line: Peak nasal inspiratory flow is the most reliable method for the assessment of nasal patency. There is no clinical need to measure peak oral inspiratory flow or to calculate. We did an investigator-initiated, open-label, randomised controlled trial at an academic hospital in China. Consecutive patients with advanced cirrhosis (Child-Pugh class B or C) and acute variceal bleeding who had been treated with vasoactive drugs plus endoscopic therapy were randomly assigned (2:1) to receive either early TIPS (done within 72 h after initial endoscopy [early TIPS group]) or.
