ARTICLE HIGHLIGHTS
Research background
Transjugular intrahepatic portosystemic shunt (TIPS) placement is widely used to treat portal hypertension. In China, TIPSs are frequently constructed using the bare metal stent (BMS)/stent-graft combination technique.
Research motivation
Stent fracture is a rare complication after TIPS placement using the BMS/stent-graft combination technique and stent fracture may cause severe consequences.
Research objectives
To assess the incidence of stent fracture after TIPS placement using the BMS/stent-graft combination technique and identify the risk factors for stent fracture.
Research methods
Retrospective cohort study.
Research results
Of the 68 included patients, stent fracture occurred in seven (10.3%) patients. The risk factors for stent fracture were the implantation of a greater number of stents [adjusted odds ratio (aOR) = 22.2, 95% confidence interval (CI): 1.2-415.4, P = 0.038] and a larger proximal sagittal stent bending angle (aOR = 1.1, 95%CI: 1.0-1.3, P = 0.020).
Research conclusions
We found three types of stent fracture occurred in 10.3% of the sample patients. The number of implanted stents and the stent bending angle at the inferior vena cava end were the independent risk factor of stent fracture.
Research perspectives
Our results suggested that the incidence of stent fracture could potentially be reduced by procedural modifications.
