Hybrid repairs, consisting of an open surgical repair combined with endovascular techniques.\n\nFurther advancement in the types of prosthesis available has resulted in the evolution of the conventional ET technique into the frozen elephant trunk (FET) technique. This utilises devices that incorporate both a traditional dacron graft (for open surgical treatment of the aortic arch) and a stented graft portion (for treatment of the descending thoracic aorta). The stented portion of the graft is introduced via an antegrade approach through the transected arch. The FET technique is now commonly used to treat patients with extensive thoracic or thoraco-abdominal aortic disease.\n\nVascutek Ltd has developed the Thoraflex™ Hybrid Device (Plexus™ 4 and Ante-Flo™) for the repair or replacement of damaged or diseased vessels of the ascending aorta, aortic arch and descending thoracic aorta in cases of aneurysm and/or dissection. The Thoraflex™ Hybrid Device is one of the commercially available frozen elephant trunk prosthesis.\n\nOver 3000 Thoraflex™ Hybrid Devices have been sold and the current study seeks to provide further evidence of the continuing safety and effectiveness of the device."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': '60 patients with acute thoracic aortic syndrome, including: acute dissection, aortic rupture and penetrating aortic ulcer (PAU)\n\n60 patients with a subacute/chronic dissection of the aorta\n\n60 patients with an aortic aneurysm', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Patient is aged 18 years or over on date of consent\n* Patient is willing and able to comply with all study procedures and study visits\n* Patient or their legally authorised representative (LAR) has given written informed consent to participate in study.
