The Frozenix J graft open stent graft has been available since 2014 in Japan. This stent is widely used for the frozen elephant trunk technique in many institutions, mainly for cases of acute type A aortic dissection and also for cases of a true aneurysm and chronic aortic dissection. We treated a rare case in which the metal wires of the Frozenix J graft were broken and embolized to the periphery half a year after being implanted.

Objective: Postoperative intraluminal thrombosis after frozen elephant trunk replacement has been reported to occur with a frequency of 6% to 17% and is associated with poor outcomes. The purpose of this institutional review is to analyze thrombosis rate, predisposing patient and operative factors, and assess different anticoagulation regimens.
Methods: This retrospective cohort study includes 174 patients operated on over 10 years.

A 65-year-old man presented with Stanford type B aortic dissection complicated by rupture of the distal aortic arch, originating from the false lumen. Due to the short distance between the supra-aortic branches, the lack of peripheral access from malperfusion, and the invasiveness of combined arch and descending aortic replacement via left thoracotomy, emergency total arch replacement with a frozen elephant trunk was chosen to close the primary entry and control the rupture. However, intraoperative deployment of the prosthesis into the false lumen was suspected due to increasing bleeding and transesophageal echocardiographic findings.

An 82-year-old man was admitted to our hospital with chest pain as a chief complaint and diagnosed with a ruptured aortic aneurysm in the distal arch by contrast-enhanced computed tomography (CT). The patient underwent surgery using artificial heart-lung and selective cerebral extracorporeal circulation, and a semi-circumferential aortic arch incision was made around the anterior surface of the aortic arch. An open stent graft was inserted through the incision, trimmed to fit the size, and the aortic wall and the stent graft were fixed with 3-0 proline continuous sutures, and finally the incision was closed with 3-0 proline.

We report a case of acute type A aortic dissection (ATAAD) with an isolated left vertebral artery (ILVA), and our successful surgical treatment with a fenestrated frozen elephant trunk (FET). A 56-year-old man was referred to our department for chest and back pain. Contrast enhanced computed tomography (CT) revealed ATAAD.

Background: Aortic arch surgery has evolved significantly with novel techniques aimed at reducing morbidity and mortality. Traditional approaches rely on hypothermic circulatory arrest (HCA), which remains associated with neurological and systemic complications. This study presents our initial experience with a normothermic frozen elephant trunk (FET) technique that eliminates circulatory arrest while maintaining continuous cerebral and systemic perfusion.
