In plain language

In 68 patients undergoing transjugular intrahepatic portosystemic shunt (TIPS), intravascular ultrasound guidance for portal vein access was linked to shorter fluoroscopy time, lower air kerma and less contrast than fluoroscopic guidance, with similar success. Staff dose was not measured.

Summary based on
the abstract

What it found

  • Intravascular US guidance reduced fluoroscopy time, air kerma, contrast volume and total procedure time compared with fluoroscopic guidance.

    Key figures: Fluoroscopy time P = .003; air kerma P = .01; contrast P = .003; procedure time P = .02

  • Intravascular US guidance reduced fluoroscopy time and contrast volume compared with marker wire guidance.

    Key figures: Fluoroscopy time P = .01; contrast P = .02

  • Technical success, hemodynamic success and complications did not differ among the three guidance techniques.

Limits to keep in mind

Small, retrospective single-series comparison of 68 patients without randomization; radiation measured as patient air kerma and fluoroscopy time, not staff dose.
