  • Adult, Older adult

Who may be able to join

  • Individuals at high risk of incomplete ablation (for example, there are vessels with a diameter greater than 3mm within 1cm around the pulmonary nodule);
  • Scheduled for lung cryoablation, meeting the surgical indications and without any specific contraindications;
  • The long diameter of the lung tumor is less than 3cm;
  • The single cryoablation needle will be used. -

Who cannot join

  • Poor image quality or incomplete images. -

About this study

Official title: This Study Aims to Provide New Evidence for Optimizing the Lung Cryoablation Strategy by Targeting High-risk Individuals With Incomplete Ice Ball Morphology in Lung Cryoablation. This is Achieved Through the Use of Selective Pulmonary Artery Embolization.

This study targeted high-risk individuals with incomplete ablation and performed selective pulmonary artery embolization before lung cryoablation, which could enhance the therapeutic effect and reduce the risk of intraoperative bleeding. Previous studies have shown that selective pulmonary artery embolization before ablation has no adverse reactions related to embolization. In this study, gelatin sponge particles were used for selective pulmonary artery embolization. Gelatin sponge is an absorbable embolic material that can be absorbed and degraded in the human body within about 7 days, which has high safety and a low probability of adverse reactions. The surgical risks are detailed in the surgical protocol. The study aims to optimize the lung cryoablation strategy for high-risk individuals with incomplete ablation, aiming to improve the prognosis of high-risk recurrent patients. The two groups of patients underwent lung CT reexamination every three months after surgery to observe the tumor ablation situation.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pulmonary artery embolizationProcedure or surgery

    In this study, using DSA guidance, gelatin sponge particles were used to artificially embolize the thicker pulmonary arteries around the tumor, thereby reducing the heat sink effect and complications, and improving the efficacy of lung cryoablation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. ablation zone

    The CT images obtained during the operation are subjected to three-dimensional reconstruction, and the ROI is delineated. The long diameter, short diameter and volume of the ablation area are measured.Compare the values of various aspects of the smiling areas between the experimental group and the control group.

    Measured: Immediately assess the extent of the ablation after the ablation needle is withdrawn.

Questions about this trial

What is this clinical trial studying?

A study testing Pulmonary artery embolization in people with Lung Cancer, run by Haibo Shao.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 19 May 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

ablation zone (time frame: Immediately assess the extent of the ablation after the ablation needle is withdrawn.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 May 2026.
