Surgical Strategy for Repair of Aortic Dissection: A Multicenter Registry

Обзор

Type A aortic dissection (TAAD) is a potentially life-threatening pathology associated with significant risk of mortality and morbidity. In acute forms of type A aortic dissection (TAAD) mortality is 50% by 24 h and 50% of patients die before reaching a specialist center. Rapid diagnosis and subsequent prompt surgical repair remain the primary goal for these patients. In the last decade it has been observed that improvements in diagnostic techniques, initial management and increased clinical awareness have contributed to a substantial increase in the number of patients benefiting from a prompt diagnosis and undergoing surgery.However, survival after surgical repair has not yet reached optimal follow-ups and is burdened by high in-hospital mortality(16-18%)The main approach to acute type B non-complicated aortic dissection (TBAD) has always been to use medicines to control the patient's heart rate and blood pressure. However, recent findings suggest that a large number of patients treated for acute complicated (TBAAD) and non-complicated TBAD experience aortic complications, such as aneurysmal degeneration, at a later stage.

Подробное описание

For patients requiring surgical repair for a TAAD, there is still some disagreement regarding which factors should be considered during the preoperative evaluation, the best decision-making process to undertake that best assesses procedural risk, and how operative mortality can be predicted. Furthermore, the impact of different surgical strategies on outcomes remains unclear.This prospective study was designed to evaluate the impact of the center volume-outcome relationship and that on mortality which remain poorly understood. A better understanding of the determinants of outcome in patients undergoing surgery could support decision making, aid in the design of service delivery, and improve outcomes for surviving patients who are referred to specialized centers for treatment of aortic disease.Furthermore, the study aims to evaluate whether precise risk stratification can provide better patient counseling and be used for unit-surgeon benchmarking. Ultimately in the present study, we aimed to investigate outcome predictors in patients undergoing surgery for TAAD, including clinical and perioperative variables as well as to evaluate follow up beyond 15 years.TBAD occurring beyond the left subclavian artery (LSA) is classified in chronological order based on the timing of clinical presentation: acute (14 days or less), subacute (more than 14 days and less than or equal to 3 months), and chronic (more than 3 months).TBADs are also divided into complicated or non-complicated based on their initial clinical manifestation. Acute complicated TBAD is characterised by tearing of the aorta, pain, rapid expansion, hypertension, or blockages in the vasculature.Malperfusion syndrome is the most common complication, occurring in nearly 30% of cases. More than 30% of patients with mesenteric compromise following aortic dissection die .

Вмешательства

• Процедура Conservative Root- Sparing Aortic Valve Resuspension with or without Hemiarch Repair
  Cardiac arrest will be performed by administering a potassium-rich antegrade cardioplegia solution delivered directly into the coronary ostium or in the case of aortic regurgitation after insertion of the coronary sinus cannula.The aorta will be resected up to the sinotubular junction and the thrombus located in the false lumen of the aortic root will be removed so that the aortic lesion can be visualized. The commissures will be resuspended using 4-0 or 5-0 sutures reinforced with a Teflon pled
• Процедура Extensive Ascending Aorta Replacement (AAR) with Aortic Root Replacement (ARR)
  Patients who experienced dilatation of the sinuses of Valsalva \> 4.5 cm in diameter on computed tomography imaging, those with connective tissue disease, or those in whom intimal tears extended into the sinuses, will receive replacement of the aortic root using a biologic or mechanical composite valve graft or valve-sparing root reimplantation procedure associated to AAR
• Процедура Extensive Ascending Aorta Replacement (AAR) with Total Arch Replacement (TARP)
  Total arch replacement procedures (TARP) will performed with the use of deep hypothermic circulatory arrest and with either antegrade or retrograde cerebral perfusion, maintaining systemic cooling between 19°C to 25°C and depending on the surgeon's practice.TARPs will be carried out using 1- and 4-branch grafts and involved the resection of all the aortic tissue up to the left common carotid artery (total arch)
• Процедура Extensive Root and Ascending Aorta Replacement with Total Arch Replacement
  This extensive procedure will include complete replacement of the anterior thoracic aorta extending to part or all of the aortic arch. It will be performed with the previously reported techniques
• Процедура Thoracic Endovascular Aortic Repair
  TEVAR patients have a higher incidence of complications and reintervention than open repair patients. TEVAR complications may include endoleak, retrograde type A aortic dissection, stent-graft migration, fracture or collapse, and increased size.
• Процедура Open Thoracic Aortic Descendig Repair
  Surveillance imaging can detect complications of open repair, such as graft infection and anastomotic pseudoaneurysm. After open repair or TEVAR, patients may develop progressive aneurysmal dilatation of adjacent or remote aortic segments.
