Purpose: To assess overall survival and to determine factors predicting outcome after thoracic endovascular aortic repair. Materials and methods: A Retrospective analysis was performed on a cohort of 212 consecutive patients (165 men and 47 women; mean age 64 years) who underwent thoracic endovascular aortic repair in a tertiary referral center for aortic disease. Main indications were true thoracic aortic aneurysm (n = 58; 27.6%), traumatic aortic rupture (n = 33; 15.7%), anastomotic pseudoaneurysms (n = 23; 10.9%), chronic type B aortic dissection (n = 22; 10.5%), and symptomatic, acute type B dissection (n = 21; 10.0%). In 79 patients (37.3%), a hybrid procedure, including supra-aortic rerouting, was performed. Kaplan–Meier estimates were used for overall survival and Cox regression models were used for univariable analysis of the association between risk factors and survival. Results: Proximal landing zones were predominantly zone 3 (n = 66; 31.3%), zone 2 (n = 63; 29.9%), and zone 1 (n = 38; 18%). In-hospital mortality was n = 18 (8.5%). Overall survival was 79.6%, 65.9%, and 51.1% at 2, 5, and 10 years, respectively; better overall survival was shown for traumatic aortic rupture, anastomotic pseudoaneurysms, and chronic posttraumatic pseudoaneurysms (p < 0.05). Clinical risk factors influencing overall survival include prior coronary bypass surgery, atrial flutter, arterial hypertension, renal failure, chronic obstructive pulmonary disease, and associated abdominal aortic aneurysm (p < 0.05). Conclusion: Thoracic endovascular aortic repair is an effective treatment option for various thoracic aortic diseases with highest survival rates for traumatic aortic rupture and anastomotic pseudoaneurysms. Several clinical parameters are identified as risk factors for overall survival.

Background The authors present two cases with type B aortic dissection initially treated by endovascular stent graft who developed aortic complications posttreatment and required surgical treatment. Case Description A 50-year-old woman and a 65-year-old man underwent endovascular treatment for thoracic aortic aneurysm associated with type B dissection and —both of them evolved with endoleak type 1. The first case was related to aortobronchial fistula, and the second one was associated with ascending aortic aneurysm. An extra-anatomical ascending aorta-supraceliac aorta bypass grafting was decided due to the persistent leak. Conclusion Surgery is an excellent choice for complex complications after thoracic endovascular aortic repair with previous failed attempts of endovascular resolution.

Objectives: Thoracic endovascular aortic repair (TEVAR) remains controversial in patients with connective tissue disorders given the concern for durability. We report on the largest series to date on outcomes of patients with thoracic aortic disease and connective tissue disorders treated with TEVAR. Methods: The Vascular Quality Initiative registry identified 12 207 patients treated with TEVAR from January 2010 to December 2018, including 102 with Marfans, Ehlers-Danlos, or Loey-Dietz syndrome. Outcomes were analyzed per the Society for Vascular Surgery reporting standards. Results: Median age was 50.6 years (interquartile range: 57.0-75.0), and 62 (60.7%) were male. Eighty-eight (86.3%) patients had Marfan, 9 (8.8%) had Ehlers-Danlos, and 5 (4.9%) had Loey-Dietz syndrome. Twenty-six (25.5%) patients were treated for degenerative aneurysmal disease and 76 (74.5%) patients for type B dissections (33 acute, 31 chronic). Most common indications for interventions in patients with type B dissection were pain (n = 41), aneurysmal degeneration (n = 16), and malperfusion (n = 8), with 3 patients who presented ruptured. There was no significant difference in perioperative complications between acute/chronic dissections and aneurysms ( P = .14). Percutaneous access was utilized in 61.7% of patients, with a 2.9% rate of arterial injury requiring reintervention. Follow-up data were available for 75 (73.3%) patients at a mean follow-up of 15.6 months. Overall mortality was 5.3%. There were 30 patients with follow-up endoleak data, and 8 (26.7%) endoleaks were identified. All endoleaks were in patients treated for acute type B dissection, and all resolved after a mean of 2.1 reinterventions. Three patients treated for acute Type B Aortic Dissection (TBAD) had retrograde dissections requiring intervention. Discussion: Thoracic endovascular aortic repair for patients with connective tissue disorders can be performed with low perioperative mortality, spinal cord ischemia, or Cerebrovascular Accident (CVA). On follow-up, acute type B aortic dissections represent a higher risk subgroup with increased rates of endoleak and retrograde dissection. Closer follow-up for these patients and early reintervention may be beneficial.

Background Unplanned stents in thoracic endovascular aortic repair mean additional stents implantation beyond the preoperative planning to achieve operation success. This study aimed to reveal the prevalence and consequences of unplanned stents in thoracic endovascular aortic repair for type B aortic dissection and explore the reasons, risk factors and solutions for unplanned stents. Methods Retrospectively analysis consecutive patients diagnosed as type B aortic dissection with initial tear originating distal from the left subclavian artery and underwent thoracic endovascular aortic repair from September 1998 to June 2014 in our center. Results Under the criteria, this study enrolled 322 patients, with 83 (25.8%) patients in unplanned group. The incidence rate of unplanned stents in thoracic endovascular aortic repair for type B aortic dissection in each year demonstrates as a bimodal curve. The curve showed that, 2003 and, 2004 was the first and highest peak and 2007 was the second peak. There was no difference in five-year survival rate between planned and unplanned patients (log-rank test, p = 0.994). The unplanned group had higher hospitalization expenses (142,699.08 ± 78,446.75 yuan vs. 175,238.58 ± 34,838.01 yuan; p = 0.019), longer operation time (104.50 ± 93.24 min vs. 179.08 ± 142.47 min; p < 0.001) and hospitalization time (17.07 ± 16.62 d vs. 24.00 ± 15.34 d; p = 0.001). The reasons for unplanned stents were type Ia endoleak (46 patients, 55.4%), bird beak (25 patients, 30.1%), and inappropriate shaping of stent (9 patients, 10.8%). Asymptomatic aortic dissection patients had higher incidence of unplanned stents. Short proximal neck length (2.66 ± 0.59 mm vs. 2.50 ± 0.51 mm; p = 0.016), short stent coverage length (154.62 ± 41.12 mm vs. 133.60 ± 44.33 mm; p = 0.002), and large distal stent oversize (75.44±10.77% vs. 82.68±15.80%; p <0.001) were risk factors for unplanned stents in thoracic endovascular aortic repair. Conclusion There are some special risk factors and reasons for unplanned stents in thoracic endovascular aortic repair for type B aortic dissection. Knowing these can we reduce the utilization of unplanned stents with appropriate methods.
