Cryoablation of Intercostal Nerves for Better Control of Postoperative Pain After Thoracic and Thoracoabdominal Open Surgery

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.

Inclusion Criteria:

• Adult patients ≥18 years
• Patients who will undergo TAA and TAAA open repair with intraoperative intercostal nerves cryoablation
• Subject has consented for study participation and signed the approved Informed Consent

Exclusion Criteria:
