Background: Stanford type A aortic dissection (STAAD) is often associated with coronary artery problems requiring coronary artery bypass grafting (CABG). However, the prognosis of different proximal graft locations remains unclear.Methods: From May 2015 to April 2020, 62 patients with acute STAAD who underwent aortic surgery concomitant with CABG were enrolled in our study. Aortic bypass was defined as connecting the proximal end of the vein bridge to the artificial aorta (SVG-AO); non-aortic bypass was defined as connecting the proximal end of the vein bridge to a non-aorta vessel, including left subclavian artery, left common carotid artery, and right brachiocephalic artery (non-SVG-AO). We compared early- and mid-term results between patients in the above two groups. Early results included death and bleeding, and mid-term results graft patency, aortic-related events, and bleeding. Grafts were evaluated by post-operative coronary computed tomography angiography. According to the Fitzgibbon classification, grade A (graft stenosis <50%) is considered a patent graft. Univariate and multivariate analyses were performed to assess differences between aortic and non-aortic bypass in STAAD.Results: SVG-AO and non-SVG-AO were performed in 15 and 47 patients, respectively. There was no significant difference in death (log-rank test, p = 0.426) or bleeding (p = 0.766) between the two groups in the short term. One year of follow-up was completed in 37 patients (eight in the SVG-AO group and 29 in the non-SVG-AO group), among which 14/15 (93.3%) grafts were patent in the SVG-AO group and 32/33 (97.0%) grafts in the non-SVG-AO at 1 week, without a significant difference (p = 0.532). At 3 months, 12/13 (92.3%) grafts were patent in the SVG-AO group and 16/32 (50.0%) grafts in the non-SVG-AO, with a significant difference (p = 0.015), and 12/13 (92.3%) grafts in the SVG-AO group and 15/32 (46.9%) grafts in the non-SVG-AO group were patents, with a significant difference. Multivariate analysis showed proximal aortic bypass and dual anticoagulation to be protective factors for the 1-year patency of grafts.Conclusion: In patients requiring aortic dissection surgery with concomitant CABG, no differencess' between SVG-AO and SVG-non-AO in early outcomes were detected, but SVG-AO may have higher mid-term patency.

Occlusion of a coronary artery by an acute type A aortic dissection presents a life-threatening emergency that is rarely seen and easy to misdiagnose. We present the case of a 75-year-old male who experienced sudden onset of severe left-sided chest pain due to an acute type A aortic dissection that obstructed the right coronary artery. Following an initial misdiagnosis of acute coronary syndrome, imaging revealed the presence of an aortic dissection. An emergency modified Bentall procedure was performed, in which the damaged aorta and aortic valve were replaced.

Short And Long Term

Acute type A aortic dissection is a surgical emergency with a high mortality rate if left untreated. Management of the aortic root in this setting constitutes an intricate decision-making framework, further complicated by the emergent nature of the dissection. There exists much controversy regarding pursuit of the aggressive aortic root replacement versus a conservative root-sparing repair, alongside considerations for valve-sparing root replacement. In this review, we critically appraise the current controversy in the literature considering the fate of the aortic root, discussing the aforementioned root interventions for which provides better outcomes for mortality and risk of re-intervention. Literature search was performed using electronic database through PubMed, Google scholar, and Embase focussing on studies reporting outcomes and re-intervention rates for these approaches. Limited by the heterogeneity in surgical strategy, with most studies being single-centred retrospective experiences, further fuel this ongoing debate. The literature reveals rather contrasting results whilst comparing root-sparing repair, versus the extensive root replacement; whilst some studies report no statistically significant difference, others show one superior over the other. There is greater consensus when considering risk of re-operation, with studies showing higher rates of re-operation in root-sparing group compared to replacement; however, many others show no statistically significant difference. In conclusion, the conflicting outcomes reported in the literature, with their inherent limitations, results in the current inability to reach a definitive answer. There remains support in the current literature for both approaches with much of the decision-making being surgeon-bound with many significant influencing factors on a case-by-case basis.

AbstractThe stent-assisted balloon-induced intimal disruption and relamination in aortic dissection or STABILISE concept is a novel endovascular strategy in Type A and Type B dissections. We report a case of Type A aortic dissection repair combining, first, an open thoracic aortic surgery with an elephant trunk procedure and, second, an endovascular treatment using the STABILISE technique via a combined transapical approach commonly used for transcatheter aortic valve implantation and a femoral pathway.

Abstract OBJECTIVES Surgery for acute type A aortic dissection (type AAD) in non-agenarians is usually contraindicated due to advanced age. The aim of this study was to assess and compare outcomes after surgical or conservative treatment for acute type AAD in non-agenarians by evaluating frailty. METHODS Between October 2012 and September 2018, 273 patients underwent open repair for type AAD at the Shonan Kamakura General Hospital and the Shonan Fujisawa Tokushukai Hospital, and here, we retrospectively reviewed the case reports of 10 surgically treated non-agenarians and 15 conservatively treated non-agenarians. Exclusion criteria for surgery were the patient’s refusal of surgery, severe dementia and coma. In patients considered to be at a high risk, our judgements were based on the results of comprehensive evaluation. RESULTS Both in-hospital mortality and 30-day mortality in the surgical group were zero, while in-hospital mortality in conservatively treated non-agenarians was 73.3%. Importantly, 1-year survival in the surgical group and conservative group was 90% and 25%, respectively. The 5-year survival in the surgical group and conservative group was 49.2% and 25%, respectively (log-rank test, P = 0.0105). Four of 6 patients with preoperative clinical frailty scores not higher than 4 were still alive at 1 year with the same level of preoperative frailty. CONCLUSIONS Surgery for acute type AAD in non-agenarians can be performed with acceptable outcomes in carefully selected patients, particularly in those with preoperative clinical frailty scores not higher than 4.

Giant pseudoaneurysm of the ascending aorta is a rare but dreadful complication occurring several months or years after aortic surgery. Thoracic aortic aneurysms tend to be asymptomatic and were previously often diagnosed only after a complication such as dissection or rupture. We present a rare case of giant ascending aneurysm with Stanford type A aortic dissection occurring 6 years after aortic valve replacement and also illustrate the potential dimensions the ascending aorta may reach by a pseudoaneurysm and dissection after AVR.
