Precision Planning in Cryotherapy for Liver Cancer

Cryotherapy for liver cancer is a perfect combination of "precision medicine" and "minimally invasive medicine", which is a representative of modern new surgical treatment mode and a major revolution in the field of liver cancer treatment. In order to achieve thorough treatment and avoid damage to important blood vessels and organs, precise preplanning is necessary.

Designing the Optimal Line of Needle Entry

Familiarize yourself with the anatomy of the Glisson system of the liver. Measure the area of each level and reconstruct a three-dimensional anatomical image centered on the tumor according to the imaging data of CT, MRI, and ultrasound. Clarify the three-dimensional structural changes between the tumor and the surrounding large blood vessels and hepatic ducts, and design the optimal needle route to avoid injury.

Design of Target Area Treatment Level

In cryoablation for liver cancer, the design of the target treatment level is crucial. Based on the area, morphology and structural depth of the tumor at each level of imaging, the relationship between the target area and the surrounding area is clarified. The diameter and number of tips are selected for the coverage of the ice ball formed by the argon helium knife.

Treatment Preplanning for Special Site Tumors

For tumors in special areas such as important blood vessels close to the liver portal, in order to avoid unnecessary damage, and at the same time should also pay attention to the influence of the "hot pool effect", need to design a plan for the puncture needle point, puncture line, freezing time.

Design of Multiple  ablation

Larger tumors often require the establishment of two to three freezing levels and the application of more than three Ar-He knives for simultaneous treatment. Multi-blade combination can cover the whole target area and achieve one-time complete cryoablation.

Overall, liver cancer cryoablation brings new treatment options for liver cancer patients with its precision and minimally invasiveness. With careful treatment planning and real-time intraoperative monitoring, Hygea Medical can ensure the thoroughness and safety of the treatment and bring better outcomes for patients.
