Embolization solution for Liver Care

Liver ASSIST

Embolization solution for Liver Care

In liver cancer treatment, due to the complex vasculature of this vital organ, it may be challenging to find the right tumor-feeding vessels to embolize or even to extract the portal system to be able to puncture it. With Liver ASSIST*, improve the sensitivity of tumor-feeding vessels identification to reach up to 97-percent2, 3, 4 and find the support your need to overcome these challenges at each stage of your procedure.


Access precise tumor feeding vessels detection in the 3D space.
Liver ASSIST provides a high sensitivity in detecting arteries leading to the vicinity of hypervascular lesions in the liver to reach up to 97% 2, 3, 4 and helps to navigate through hypervascularized anatomy of the liver to reach the lesion.


Save time and radiation dose.
• Placing catheter tip at the right location usually requires constant change of catheters & guidewires to find the right one in selectivity.
• Detecting tumor feeding vessels in the 3D space usually requires multiple DSA in various angulations (meaning increased dose and procedure time to obtain comprehensive understanding of the 3D vascular anatomy
• Liver ASSIST allows to save procedural time by 11% and helps to reduce mean number of DSA by up to -30%6 in a single TACE session.


Achieve a higher rate of complete tumor response.
Liver ASSIST is the only software solution able to demonstrate ~68% complete tumor response rate (36% with DSA alone)5


Optimizes procedure selection & preparation.
Thanks to automatic liver anatomy segmentation & evaluation, Liver ASSIST helps to automatically extract bone, liver and portal system7 to be able to puncture it during your TIPS or PVE procedures.

Trans Arterial ChemoEmbolization

To deliver therapeutic material to tumors during trans-arterial chemoembolization therapy, it is essential to identify the liver vessels accurately. But the liver’s complex vasculature can make precise identification of tumor-feeding vessels in 2D and 3D images a challenge, often requiring significant time, radiation, and contrast media.


PLAN

Liver ASSIST has demonstrated its ability to deliver high sensitivity in identifying tumor-feeding vessels which are automatically highlighted through an intuitive 3-step workflow.

GUIDE

With single-click fusion imaging between the live fluoroscopic image and the vessels highlighted, Liver ASSIST facilitates catheter selection and guidance in complex vascular anatomies for a higher selectivity in liver embolization procedures.

ASSESS

The outcome of the treatment using Liver ASSIST during the planning and guidance steps is then controlled with 3DCT HD and AW VolumeShare7

PLAN

With Autobone and Liver ASSIST, automatically extract bone, liver and portal systems.7
Export to use as a 3D overlay.

GUIDE

With Vision 2 overlay pre-operative data on live fluoroscopic images using the intuitive Bi-View registration guided workflow, all at table side.

    GE solutions address endovascular & ablative care with diversified solutions
  • alert

    Liver ASSIST, is the only software solution able to demonstrate ~68% complete tumor response rate (36% with DSA alone)5

  • Liver ASSIST improves the sensitivity of Tumor-feeding vessels identification versus the use of either DSA or Cone Beam CT alone, to reach up to 97%.2, 3, 4

     

  • Thanks to Liver ASSIST, up to 82% inter-operator agreement for identification of feeding vessels compared to DSA(54%) or Cone Beam CT(62%) alone.
  • 11% reduction in procedure time 6
    Procedure time comparison with versus without Liver ASSIST in a single TACE session

* Liver ASSIST solution includes Hepatic VCAR and FlightPlan for Liver that can be used independently. It also requires an AW workstation with Volume Viewer and Volume Viewer Innova. These applications are sold separately. Not available in all markets.
