ABSTRACT

The treatment of complex aortic arch disease, in chronic or acute setting, has always represented a fascinating challenge for the heart surgeon also because, often, the involvement of the aortic arch is associated with a simultaneous involvement of the ascending aorta and of the proximal portion of the descending thoracic aorta. In recent years, there have been many surgical and/or endovascular techniques and approaches in a single step or multiple steps proposed with the aim of treating and simplifying these complex conditions. The first procedure available for this purpose was the conventional elephant trunk technique, proposed by the German surgeon Hans Borst, back in 1983. In the following years, the technique has undergone modifications, up to what is nowadays considered its most modern evolution, represented by the frozen elephant trunk which allows managing the proximal descending thoracic aorta using the antegrade release of a self-expandable stent graft. In this review article, we try to analyze the advantages and drawbacks of both techniques from clinical and practical points of view.

ABSTRACT

IgG4-related aortitis is an inflammatory condition of the aorta, characterized by aortic wall thickening and periaortic soft-tissue involvement. Therefore, this condition can mimic an aortic intramural hematoma (IMH), due to similar radiological findings. We hereby report the case of an IgG4-related aortitis misdiagnosed as an IMH, associated with cerebral hemorrhage, possibly due to cerebral vascular system involvement.

ABSTRACT

Aberrant right subclavian artery is a relatively rare congenital anomaly of the aortic arch. A 74-year-old woman was referred to our cardiac surgery department for chest pain. Computed tomography angiography scan showed an acute aortic dissection and revealed an aberrant right subclavian artery routed behind the trachea. We performed supracoronary ascending aorta and total arch replacement with the frozen elephant trunk technique. The aberrant right subclavian artery was then anastomosed termino-terminal to one branch of the Thoraflex (Vascutek, Glasgow, Scotland) arch graft. Postoperative computed tomography scan indicated a successful reconstruction of the aortic arch, proving the open stent-grafting technique as a useful and effective approach for aortic disease with aberrant right subclavian artery.

ABSTRACT

OBJECTIVES: The introduction of selective antegrade cerebral perfusion technique as method of cerebral protection improved the outcome of open arch surgery. The aim of this study was to report early outcomes using this technique. METHODS: Between 1997 and 2017, data were collected retrospectively for all patients who underwent surgical replacement of the aortic arch using selective antegrade cerebral perfusion (n = 938). To confirm the effectiveness of this cerebral protection method, early outcome and results were evaluated. RESULTS: The incidence of postoperative permanent neurological dysfunction was 6.4%. Overall hospital mortality was 11.9% (n = 112). On multivariable analysis, age >75 years, female gender, euroscore at increment of 1 point, chronic renal failure, extension of thoracic aorta replacement and CPB time emerged as independent risk factors for hospital mortality. The mid-term survival at 1, 5, 10 and 15 years was 92%, 78%, 60% and 49%, respectively. The competing risk analysis for permanent neurological dysfunction and aortic reoperations was performed excluding the patients who died during the hospital stay. The cumulative incidence of permanent neurological dysfunction and aortic reoperations was 2% at 3 years, 3% at 5 years, 6% at 10 years, 12% at 3 years, 15% at 5 years and 19% at 10 years, respectively. CONCLUSIONS: From the early 90s to the present day, the selective antegrade cerebral perfusion has confirmed to be a useful and "safe" method of brain protection in aortic arch surgery in terms of postoperative neurological complications.

ABSTRACT

BACKGROUND: The aims of this study were to analyse the incidence of visceral malperfusion syndrome (MPS) following Frozen Elephant trunk operations in patients affected by chronic aortic dissection and the associated risk factors. METHODS: Between January 2007 and February 2019, 165 patients underwent surgery with FET for chronic aortic dissection. Post-operative computer tomography angiogram parameters (diameters, early post-operative false lumen enhancement and involving of aortic branches by the dissection) were collected and analysed to evaluate their impact on the occurrence of visceral malperfusion. RESULTS: Visceral (renal and mesenteric) MPS (with both clinical and radiological signs of MPS) was detected in 10 cases (6.1%). Post-operative visceral malperfusion was strongly related with in hospital mortality. The involvement of the visceral branches in the dissection was not a risk factor for visceral malperfusion occurrence, while a larger post-operative total aortic diameter at level of the coeliac trunk increased the risk of visceral MPS (OR 1.05; CI 1.002-1.102, p-value = 0.04). Furthermore, visceral MPS was associated to a complete thrombosis of the false lumen at level of the distal descending thoracic aorta. CONCLUSIONS: The development of post-operative MPS in frozen elephant trunk is strongly related to in-hospital mortality. The involvement of aortic branches by the dissection does not represent a real predictive risk factor for MPS, while early larger aortic diameters and false lumen thrombosis represent independent risk factors for MPS and in-hospital mortality.

ABSTRACT

An anomalous origin of the left circumflex coronary artery that arises as a side branch of the right coronary artery and encircles the aortic annulus is usually an incidental finding. However, in patients undergoing aortic valve/root procedures, its existence can significantly complicate the surgical treatment. We report our operative strategy with three different prostheses without valve downsizing.

ABSTRACT

The presence of a coronary arteriovenous fistula is almost rare in the adult population, even rare when associated with aortic valve insufficiency. Management and treatment options can vary and depend on a single patient. In our case, a large fistula with a rounded origin started from the roof of the left main stem, just attached to the wall of the aortic root, and finished with a very narrowed end in the pulmonary trunk. Due to its anatomical position and to the potential complications related to a proximal surgical closure as well as the incidental discovery in adult age (without signs or symptoms until the operation), we decided to have a conservative approach, leaving untouched the fistula. No intraoperative, perioperative, and follow-up signs of myocardial ischemia were observed.

ABSTRACT

The best surgical treatment for acute type A aortic dissection (AAAD) is still a strongly debated issue of every cardiac surgeon. The successful result is obtained by taking into consideration both the preoperative and intraoperative aspects, such as cerebral, visceral or coronary malperfusion before surgery. More conservative approaches or more aggressive treatments are different strategies with their pros and cons to face the same problem, especially for the aortic arch management. The expertise of the center, the perfect surgical timing and a dedicated aortic team composed of expert aortic surgeons, anesthesiologist, radiologist and cardiologist are important but not mandatory to achieve the best results in this type of surgery since is not possible to offer it in all the hospitals. The accurate assessment of the aortic anatomy has to be performed, including the extension of the dissection process, the exact location of the entry and re-entry tears, the aortic diameters, the distribution of visceral vessels between the true and the false lumen and the assessment of perfect size of the prosthesis to avoid the oversize since it may cause new entry site in the descending thoracic aorta. We reviewed and analyzed different scenarios and techniques used for the aortic arch replacement in patients with AAAD, taking into consideration that the aim of surgery is to save patients life.

ABSTRACT

The decision-making process is crucial for the surgery of acute type A aortic dissection (AAAD). Often surgeons have to face different challenges, taking prompt decisions in emergency setting, during the pre- and intraoperative phase. Choosing if operate or not a patients with AAAD as well as the management of the dissected aortic arch can be challenging. Different factors need to be evaluated as: the patients age, the presence of organ malperfusion, the intimal tear location, and last but not least the surgeon personal experience in aortic surgery. During the last decade, different milestone steps have been achieved in aortic surgery as the antegrade perfusion of the aorta through different cannulation sites, open distal repair, antegrade selective cerebral perfusion, and systematic resection of the proximal intimal tear, allowing complex repair for dedicated team as well as simpler repair for not dedicated surgeons. We reviewed different scenarios and techniques used for the aortic arch replacement in patients with AAAD, taking into consideration that the aim of surgery is to save patients life.

ABSTRACT

OBJECTIVES: We compared the results of 2 groups of patients who underwent aortic arch replacement with the frozen elephant trunk technique. In the first group, the distal anastomosis was performed in arch zone 2; in the second control group, the distal anastomosis was performed in arch zone 3. METHODS: Between January 2007 and April 2018, the frozen elephant trunk technique was used in 282 patients. The median age was 62 years (range 18-83 years), and 233 patients were men (82.6%). Two different frozen elephant trunk prostheses were used: the Jotec E-vita open prosthesis in 167 patients (59.2%) and the Vascutek Thoraflex hybrid prosthesis in 115 patients (40.8%). Patients were divided into 2 groups according to the distal anastomosis site: zone 2 group (69 patients) and zone 3 group (213 patients). The main indications were chronic aortic dissection (n = 164, 58.2%), degenerative aneurysm (n = 72, 25.5%) and acute aortic dissections (n = 45, 16%). RESULTS: The overall in-hospital mortality rate was 17%: 20% for the zone 2 group and 16% for the zone 3 group, without significant differences, also in terms of cardiopulmonary bypass and myocardial ischaemia times. However, the visceral ischaemia time was significantly shorter for the zone 2 group, whereas the antegrade selective cerebral perfusion time was significantly longer for the same group. Recurrent laryngeal nerve injury rate was lower in the zone 2 group. The overall postoperative paraplegia rate was 3.5%, whereas the occurrence of permanent neurological dysfunction and dialysis was 9% and 19%, respectively, with no significant differences between the groups. CONCLUSIONS: 'Proximalization' of the distal anastomosis can be used for arch reconstruction, especially in complex cases such as reoperations or acute aortic dissections. Furthermore, with the aid of branched hybrid grafts, a reduction of the visceral ischaemia time is achieved.

ABSTRACT

The elephant trunks, either conventional or frozen represent the major technical improvements in the treatment of complex thoracic aortic disease. In the last decades, these useful techniques progressively evolved along with the introduction of new devices to facilitate the procedure and ameliorate post-operative results. The latest multi-branched hybrid FET prostheses give us the opportunity to greatly facilitate graft implantation and reduce operative times. The following review will provide an overview of the FET technique throughout the current available devices, possible surgical indications and principal surgical steps.

ABSTRACT

We present a case of a 48-year-old female patient with Marfan syndrome and previous open surgeries for Bentall procedure and arch replacement with frozen elephant trunk (FET) technique, who was admitted at our Department with a diagnosis of ascending aorta pseudoaneurysm at the anastomosis-site between composite valve graft and arch prosthesis treated by endovascular procedure because of she was considered to be at high-risk for a third open surgery and for the patient's favorable anatomy for endovascular closure of the pseudoaneurysm. The patient was successfully treated with the positioning of two abdominal cuffs through the left axillary artery. The postoperative course was uneventful and at 2-month follow-up, the patient was free of complications with CT angiogram showing complete endovascular exclusion of the pseudoaneurysm.
