Background: Uncomplicated Stanford Type B aortic dissection (un-TBAD) is characterised by a tear in the aorta distal to the left subclavian artery without ascending aorta and arch involvement. Optimised cardiovascular control (blood pressure and heart rate) is the current gold standard treatment according to current international guidelines. However, emerging evidence indicates that Thoracic Endovascular Aortic Repair (TEVAR) is both safe and effective in the treatment of un-TBAD with improved long-term survival outcomes in combination with optimal medical therapy (OMT) relative to OMT alone. However, the optimal timeframe for intervention is not entirely clarified. Aims: This review critically addresses current state-of-the-art comparing TEVAR with OMT and corresponding clinical outcomes for un-TBAD based on timing of intervention. Methods: We carried out a comprehensive literature search on multiple electronic databases including PUBMED and Scopus in order to collate all research evidence on timing of TEVAR in uncomplicated Type B aortic dissection. Results: TEVAR has proven to be a safe and effective treatment for un-TBAD in combination with OMT through comparable survival outcomes, improved aortic remodelling, and relatively low periprocedural added risks. Though the timing of intervention remains controversial, it is becoming clear that performing TEVAR during the subacute phase of un-TBAD yields better outcomes compared to earlier and delayed (>90 days) intervention. Conclusions: Further research is required into both short and long-term outcomes of TEVAR in addition to its optimal therapeutic window for un-TBAD. With stronger evidence, TEVAR is likely to be adopted as the gold-standard intervention for un-TBAD with definitive timeframe guidelines.

Abstract OBJECTIVES To study the perioperative outcomes and long-term survival rates in patients undergoing thoracic endovascular aortic repair (TEVAR) for uncomplicated type B dissection. METHODS A total of 751 patients with uncomplicated type B dissection who underwent TEVAR at our centre between May 2001 and December 2013 were retrospectively reviewed. The mean age of all patients (619 males and 132 females) was 52.8 ± 10.9 years. The follow-up period ranged from 1 to 170 months (median 70 months). RESULTS Five patients died during the perioperative period (mortality rate 0.7%). Four patients (0.5%) developed retrograde type A dissection. Two patients (0.3%) developed paraplegia and 1 patient developed incomplete paralysis (0.1%). There were no postoperative cerebral infarctions. The 5- and 10-year survival rates were 96.5% [95% confidence interval (CI) 95.0–98.0%] and 83.0% (95% CI 77.9–88.4%), respectively. The 5- and 10-year reintervention rates were 4.6% (95% CI 3.0–6.2%) and 7.9% (95% CI 5.3–10.5%), respectively. CONCLUSIONS Although the application of TEVAR for patients with uncomplicated dissection is still under debate, many patients who have undergone TEVAR have benefitted substantially from the treatment. Our data showed that TEVAR had low mortality and complication rates both in the short- and long-term follow-up periods. TEVAR may be considered as a first choice for patients with uncomplicated type B dissection.

Abstract Background Postoperative thrombocytopenia has been reported to be correlated with adverse events, but the prognostic value of baseline thrombocytopenia is unclear. This study was undertaken to evaluate the relationship between preoperative thrombocytopenia and adverse outcomes in patients with type B aortic dissection who underwent thoracic endovascular aortic repair (TEVAR). Methods A total of 825 patients with acute and sub-acute type B aortic dissection undergoing were TEVAR at a multidisciplinary aortic center were enrolled between January 2010 and December 2017. Patients were stratified on the basis of presence (n=149) or absence (n=676) of thrombocytopenia (platelet count, <150x109/L), according to preprocedural platelet counts. The primary outcome of interest was in-hospital mortality. Secondary outcomes of interest was long-term death. Results In the enrolled cohort, thrombocytopenia occurred in 149 (18.1%) patients. Patients with thrombocytopenia were older, were more commonly acute stage of TBAD, higher D-dimer level and had higher rates of abdominal vessel involvement and pericardial effusion. During the hospitalization period, 26 patients (3.2%) died, which was significantly higher in the thrombocytopenic group (8.1% versus 2.1%; P=0.001) Multivariate analyses revealed that thrombocytopenia was independently associated with in-hospital mortality (Table). During long-term follow-up (median duration 44.2 months), A total of 62 deaths were reported after discharge, including 40 (64.5%) aortic-related and unknown deaths, of which 12 and 50 patients for thrombocytopenia and non-thrombocytopenia group, respectively. Kaplan-Meier estimated rates of long-term all-cause mortality were higher for thrombocytopenia (log-rank test, P=0.014). Similar results were observed in a subset of aortic-related death (P=0.004) as well as aortic-related and unknown death (P=0.006), not non-aortic related death (P=0.878) (Figure 1). Conclusion Platelet counts, as simple and inexpensive indexes, were reliable to be used as a preoperative risk assessment tool for patients with type B aortic dissection undergoing thoracic endovascular aortic repair.
