This study evaluated the role of US-based parameters in detecting hemodynamic TIPS dysfunction (HD).<\/jats:p><jats:p>\n          Methods\u2002 We included consecutive patients treated with TIPS. All patients were scheduled within the first six weeks after the procedure for TIPS revision, comprised of a Doppler US exam and invasive hemodynamic reassessment. Clinical TIPS dysfunction (CD) was defined as symptom recurrence, while HD was defined by a portal pressure gradient (PPG)\u226512 mmHg. The predictive capabilities of Doppler US for predicting TIPS dysfunction were tested against the hemodynamic gold standard.<\/jats:p><jats:p>\n          Results\u2002 86 patients were included. Secondary prophylaxis of variceal bleeding was the main indication for TIPS in 72 patients (83.7%), while 27 (31.4%) had refractory ascites. HD occurred in 37 cases (43%), of which 25 patients (67.5%) had no CD. Patients with HD had a significantly lower portal vein velocity (PVV): 35 (20\u201345) cm\/s vs. 40.5 (35\u201350) cm\/s, p=0.02. Compared to the immediate post-TIPS assessment, the patients without HD had a \u0394PVV of 6.08\u00b119.8 cm\/s vs. a decrease of \u2212\u20098.2\u00b120.2 cm\/s in HD (p=0.04). Using a cut-off value of 40.5 cm\/s, PVV had an AUROC of 0.705 for predicting HD, while the addition of \u0394PVV (cut-off 9.5 cm\/s) improved the AUROC to 0.78.<\/jats:p><jats:p>\n          Conclusion\u2002 Despite adequate symptom control, a considerable percentage of patients have a post-TIPS PPG\u226512 mmHg. The dynamic assessment of PVV and its temporal dynamics can reliably predict TIPS dysfunction.<\/jats:p>","DOI":"10.1055\/a-2422-8339","type":"journal-article","created":{"date-parts":[[2024,12,18]],"date-time":"2024-12-18T00:23:37Z","timestamp":1734481417000},"source":"Crossref","is-referenced-by-count":1,"special_numbering":"S","title":["Portal vein velocity and its dynamics: a potentially useful tool for detecting clinically silent transjugular intrahepatic porto-systemic shunt dysfunction using Doppler ultrasonography"],"prefix":"10.1055","volume":"10","author":[{"given":"Zeno","family":"Sp\u00e2rchez","sequence":"first","affiliation":[{"name":"Internal Medicine Department, Iuliu Hatieganu University of Medicine and Pharmacy, Cluj-Napoca, Romania"},{"name":"Gastroenterology Department, Prof. Dr. O.
