Trial summary

The purpose of the registry is to evaluate the peri-operative and short- term outcomes of intercostal nerves cryoablation for post-operative pain control after open thoracic and thoracoabdominal aortic aneurysms repair. The cryoablation procedure is one of the opportunities for pain control after thoracotomy. Read more about this study

About this study

Official title: Cryoablation of Intercostal Nerves for Better Control of Postoperative Pain After Thoracic and Thoracoabdominal Open Surgery - A Physician-initiated, International, Multicentre, Prospective, Observational Registry of Patients Undergoing Open Thoracic (TAA) and Thoracoabdominal Aortic Aneurysms Repair (TAAA) Using Cryoablation of Intercostal Nerves to Improve Postoperative Pain Control. (Cryo Registry)

The purpose of the registry is to evaluate the peri-operative and short- term outcomes of intercostal nerves cryoablation for post-operative pain control after open thoracic and thoracoabdominal aortic aneurysms repair.

The cryoablation procedure is one of the opportunities for pain control after thoracotomy. So, it is routinely performed in major several centers in aortic surgery around the world as a part of the TAA and TAAA procedure.

The Registry will include approximately 200 patients treated from January 2022 to January 2024 for thoracic or thoracoabdominal aortic aneurysm by means of open surgery and in whom intraoperative intercostal nerves cryoablation will be performed; to reach 200 patients, the enrolments can be extended until January 2027.

What participants receive

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

  • Open thoracic (TAA) and thoracoabdominal aortic aneurysms repair (TAAA)Procedure or surgery

    Each participating center will be able to use its preferred European Conformity marked device, for cryoablation according to their normal clinical practice and according to the instructions for use.

What is being measured

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

  1. technical success

    Freedom from Death

    Measured: From Admission to 1 years

  2. change in dose of narcotic administration

    reduction opioids usage for thoracic incision pain

    Measured: From Admission to 1 years

  3. Primary clinical success

    pain control defined as a visual analogic scale < 5 in the perioperative period up to the discharge

    Measured: up to 3 weeks

  4. secondary clinical success

    pain control in in the perioperative period up to the discharge, using analgesic non opioids drugs

    Measured: up to 3 weeks

Are results available for this study?

Results are not available in the source record.

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?

technical success (time frame: From Admission to 1 years). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05153083, which also lists 10 linked publications.

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?
