OBJECTIVES Our goal was to review our surgical experiences in patients with complex pathologies of the aortic arch who have undergone anterolateral thoracotomy with a partial sternotomy (ALPS). METHODS From October 2019 to November 2023, a total of 23 patients underwent one-stage repairs of complex pathologies of the aortic arch through the ALPS approach. The mean age was 61.9 ± 16.7 years old. The aortic pathologies were as follows: aorta-related infection in 11 (aorto-oesophageal fistula: 4, graft infection: 6, native aortic infection: 1); aortic dissection in 9 including shaggy aorta in 2, non-dissecting aneurysm in 1, and coarctation of the aorta (CoA) in 2. RESULTS Eighteen patients underwent aortic replacement from either the sinotubular junction or the ascending aorta to the descending aorta; 1 patient underwent it from the aortic root to the descending aorta (redo Bentall procedure and extensive aortic arch replacement); 3 patients underwent it from the aortic arch between the left carotid artery and left subclavian artery to the descending aorta; and 1 patient underwent a descending aortic replacement. Ten patients underwent omentopexy, latissimus dorsi muscle flap installation or both procedures. The hospital mortality rate was 13.0% (3/23). The overall survival and freedom from aortic events were 73.3%±10.2% and 74.1%±10.2%, respectively, at the 3-year follow-up. There was an absence of aorta-related deaths, and no recurrent infections were identified. CONCLUSIONS The short-term outcomes using the ALPS approach for the treatment of complex pathologies of the aortic arch were acceptable. Further studies will be required to determine the long-term results. [ABSTRACT FROM AUTHOR]

A 59-year-old male underwent Bio-Bentall + total arch replacement with a frozen elephant trunk for acute type A aortic dissection before at another hospital. He was diagnosed as mediastinitis and previous graft infection, followed by wound closure with omental flap installation. However, the recurrent graft infection from the aortic root to the FET in the descending aorta was diagnosed by 18-fluorodeoxyglucose positron emission tomography. Redo modified Bio-Bentall procedure, total arch replacement, and descending aortic replacement for previous graft infection using anterolateral thoracotomy with partial sternotomy was successfully performed. Anterolateral thoracotomy with partial sternotomy provided not only the excellent exposure from the aortic root to the descending aorta but also sure myocardial protection with antegrade and selective delivery of cold crystalloid cardioplegia and stable brain protection with antegrade selective cerebral perfusion. The patient is doing well without recurrent of infection after 2 years of the operation. [ABSTRACT FROM AUTHOR]

METHODS Between October 1999 and March 2018, a total of 740 patients underwent total arch replacement. After excluding connective tissue disease, previous descending or thoracoabdominal aortic surgery, patients without adequate preoperative images or operative mortality, late outcomes consisting of additional surgery for distal dilation and distal aortic events were evaluated in 623 survivors (240 aortic dissections, including 139 patients with acute dissection and 383 with a non-dissection aneurysm). The mean follow-up was 5.0 ± 4.0 years. RESULTS The mean preoperative maximum diameter of the descending aorta was 36.9 ± 8.0 mm. An elephant trunk was inserted in 232 patients, including 183 patients with aortic dissection. Freedom from additional surgery for distal dilation was 88.5% at 5 years and 80.2% at 10 years. Freedom from distal aortic events was 81.9% at 5 years and 70.5% at 10 years. Multivariable regression analysis demonstrated that the preoperative diameter of the descending aorta was a significant risk factor for unfavourable distal aortic events. Computed tomography evaluation demonstrated a significant increase in the descending aortic diameter over time (P  < 0.001). Positive aortic remodelling was observed in the proximal descending (P  < 0.001) to mid-descending (P  < 0.001) aorta exclusively in patients with acute aortic dissection. CONCLUSIONS The diameter of the descending aorta increased significantly after total arch replacement, particularly in the distal descending aorta. The preoperative descending aortic diameter portended a significant risk for unfavourable distal aortic events. [ABSTRACT FROM AUTHOR]

Minimization of end-organ ischemia is a key tenet in successful thoracoabdominal aortic aneurysm (TAAA) surgery. During these reattachments, antegrade pulsatile blood flow to the spinal cord was guaranteed not only via the Adamkiewicz artery but also the collateral network, which ultimately minimizes spinal cord ischemia. Therefore, the question remains whether the incidence of spinal cord ischemia in patients with atherothrombotic aorta could be reduced by the current technique. [Extracted from the article]
