Thoracic aortic dissection (AD) is associated with increased morbidity and mortality. Acute aortic syndrome is the first presentation of the disease in most cases. While acute AD management follows concrete guidelines because of its urgent and life-threatening nature, chronic AD is usually overlooked, although it concerns a wide spectrum of patients surviving an acute event. Acute AD survivors ultimately enter a chronic aortic disease course. Patients with chronic thoracic AD (CTAD) require lifelong surveillance and a proportion of them may present with symptoms and late complications demanding further surgical or endovascular treatment. However, the available data concerning the management of CTAD is sparse in the literature. The management of patients with CTAD is challenging as far as determining the best medical therapy and deciding on intervention are concerned. Until recently, there were no guidelines or recommendations for imaging surveillance in patients with chronic AD. The diagnostic methods for imaging aortic diseases have been improved, while the data on new endovascular and surgical approaches has increased significantly. In this review, we summarize the current evidence in the diagnosis and management of CTAD and the latest recommendations for the surgical/endovascular aortic repair of CTAD.

A remarkable increase in the number of patients presenting with tracheal complications after prolonged endotracheal intubation and mechanical ventilation for the management of the severe COVID-19-associated respiratory failure has been observed. In this study, we assessed the postoperative outcomes of tracheal resection in patients with COVID-19. We conducted a retrospective study in which all patients with a history of prolonged invasive mechanical ventilation due to COVID-19 infection, who were treated with tracheal resection and reconstruction, were included. The primary objective was in-hospital mortality and postoperative reintervention rate. The secondary objective was the time to tracheal restenosis. During the 16-month study period, 11 patients with COVID-19 with tracheal complications underwent tracheal resection with end-to-end anastomosis. Mean patient age was 51.5 ± 9 years, and the majority were male (9 patients). Eight patients were referred for management of postintubation tracheal stenosis, and 3 patients were referred for tracheoesophageal fistula. Eight patients had a history of tracheostomy during the COVID-19 infection hospitalization. There was 1 in-hospital death (9.1%) due to septicemia in the intensive care unit approximately 2 months after the operation. Postoperatively, 32 reinterventions were required for tracheal restenosis due to granulation tissue formation. The risk for reintervention was higher during the first 3 months after the index operation. Four patients developed tracheal restenosis (36.4%), and 2 of them required endotracheal stent placement during the follow-up period. Tracheal resection and reconstruction after COVID-19 infection are associated with a high reintervention rate postoperatively. Such patients require close follow-up in expert interventional pulmonology units, and physicians should be on high alert for the early diagnosis and optimal management of tracheal restenosis.
