Purpose We report a case of significant air embolization to the ascending aorta immediately following deployment of EndoAnchors in the aortic arch during a procedure to correct a type 1A endoleak. Case report The novel Heli-Fx EndoAnchor system (Medtronic Vascular, Santa Rosa, CA, USA) was used to deploy helical anchors in the distal aortic arch during a procedure to correct a type 1A endoleak following Zone 2 thoracic endovascular aortic repair of a saccular proximal descending thoracic aorta aneurysm (DTAA). The patient developed ST-segment elevations principally in the inferior leads and severe hypotension moments after EndoAnchor deployment at the proximal edge of the endograft. Transesophageal echocardiogram revealed severe right ventricular hypokinesis and a large amount of air in the ascending aorta. Subsequent management and clinical and radiological 30-day follow-up is presented in addition to a review of the literature and ex vivo testing with the Heli-Fx system to examine potential causes and solutions. Conclusion Precautions, such as pressurized saline infusion to the side port of guiding sheath, should be used whenever manipulating catheters and sheaths such as the EndoAnchor system in the aortic arch to prevent this potentially lethal complication.

We report a successful treatment of type A acute aortic syndrome (AAS)-associated aortic arch aneurysm in a 71-year-old man with major comorbidities. The ascending aorta was wrapped with artificial graft, and supra-aortic debranching was constructed. Then, Zone 0 thoracic endovascular aneurysm repair (TEVAR) with plug occlusion of the left subclavian artery was successfully performed. The patient was discharged in good physical condition without any complications. To our knowledge, this is the first reported case in the literature of successful Zone 0 TEVAR after ascending aorta wrapping and supra-aortic debranching with type A AAS associated with aortic arch aneurysm.

<p><strong>Aim:</strong> The study was designed to summarize short-term results of aortic valve reimplantation (David procedure) in patients suffering from thoracic aorta aneurysm and aortic valve insufficiency. <br /><strong>Methods:</strong> 132 patients were operated for various types of aorta pathology and aortic valve insufficiency, including 56 patients with acute and subacute aortic dissection and 76 patients with chronic aortic aneurysm with or without dissection. Different types of surgical interventions were offered to patients: ascending aorta replacement with aortic valve reimplantation (88 cases), hemiarch replacement (11 cases), Borst procedure (17 cases), stent-graft implantation (16 cases) and other concomitant interventions including CABG, valve repair or replacement. The efficacy of aortic valve functioning was evaluated by using intraoperative transoesophageal ultrasound imaging in 129 cases and transthoracic ultrasound imaging in immediate postoperative period in 119 cases. <br /><strong>Results:</strong> Satisfactory hemodynamic parameters of aortic valve functioning were recorded in the majority of patients: Grade 0 aortic insufficiency - 10 patients, Grade 1-1+ - 100 patients and Grade 2-2+ was registered in 10 patients. Despite the fact that functional parameters of the aortic valve following the David procedure were positive in most patients, overall hospital mortality ran to 12.1% (16 patients). Hospital mortality depended on the nature of intervention (emergency or elective surgery), as well as on the general complexity related with the extent of the intervention. In the group of patients who underwent emergency and elective interventions, hospital mortality accounted for 19.6% (11 patients) and 6.5% (5 patients) respectively. <br /><strong>Conclusion:</strong> David procedure in patients suffering from ascending aorta aneurysm is an effective treatment option in terms of aortic valve functional recovery in cases of acute or chronic aortic valve insufficiency.</p>

Ascending aorta aneurysm and aortic arch aneurysm surgery remain some of the most complex problems that cardiovascular surgeons face. It stems from the need for the correction of the underlying pathology while simultaneously adequately protecting the brain and visceral arteries. Purpose. The aim of our study was to determine the incidence of post-surgical complications and the immediate post-surgical results of surgical treatment of ascending aorta aneurysms and/or aortic arch aneurysms. Materials and methods. During the twelve-year period of 1994– 2016, we have surgically operated on a total of 317 patients aneurysms of the ascending aorta and/or the aortic arch. The method we employed to diagnose the aneurysms consisted of evaluating the patients’ medical history, transthoracic and transesophageal echocardiographies, computer tomographies, X-ray examinations, and aortographies. All of the 317 surgeries were performed on the patients under general anaesthesia, and the incision via the the median sternotomy, employing the use of a heart-lung machine. Valve sparing technique with aortic valve resuspension / valvuloplasty and hemiarch/arch replacement – 221/6 patients (69.7 %). Bentall procedure with hemiarch/arch replacement – 67/4 (21.1 %). Other surgeries – 29 (9.2 % of patients). Results and discussion. The history of aortic aneurysm development is briefly mentioned in the paper. The diagnostic methods presented are currently the primary method of computer tomography. The initial condition of the patients was serious enough. All surgeries were performed through a median sternotomy and with the use of heart-lung machine. For surgical treatment of aneurysms the following techniques were used: напівдуги/дуги – у 221/6 (69,7 %) хворих. У цій групі 7 операцій Yacoub, 3 операції David. У 7 пацієнтів виконана плікація однієї зі стулок при пролапсі аортального клапана. Укріплення вільного краю стулки виконано в 3 хворих, пластика латкою фенестрацій стулки аортального клапана – у 4; 2) операція Bentall з протезуванням напівдуги/дуги – у 67/4 (21,1 %); 3) інші – ізольоване протезування дуги – у 14 (4,4 %); операція Wheat + протезування дуги – у 6 (1,9%); пластика дуги аорти – у 4 (1,3 %); гібридні операції Elephant trunk (conventional Elephant trunk) + TEVAR – у 5 (1,6 %). Захист головного мозку виконувався по-різному на кожному із трьох етапів хірургічного досвіду. Найкращий результат досягнутий на 3 етапі: з 229 прооперованих померли 9 хворих (3,9 %). Також у лікуванні використано сучасний ендоваскулярний метод – гібридні операції Elephant trunk + TEVAR – у 5 (1,6 %) з хорошим безпосереднім результатом. Висновки. 1. При розшаруванні аорти типу А (І тип за De Bakey) операцією вибору є супракоронарне протезування з півдугою (дугою) аорти. 2. Накопичення хірургічного досвіду, вишкіл команди, удосконалення методик захисту головного мозку й вісцеральних органів – дозволили знизити кількість післяопераційних ускладнень з 64 % до 8,7 % і госпітальну летальність з 28 % до 3,9 %. Ключові слова: аневризма дуги, розшарувальна аневризма, глибока гіпотермія, ретроградна церебральна перфузія.
