Abstract
Purpose: Thoracic endovascular aortic repair (TEVAR) with left subclavian artery (LSA) revascularization has been used in patients with type B aortic dissection (TBAD), with inadequate proximal landing zone (PLZ). The outcomes of comparisons between TEVAR and hybrid procedure on patients with TBAD, with inadequate PLZ, are rarely reported. This study sought to compare and clarify the early and midterm outcomes between TEVAR and hybrid procedure in patients with TBAD, with inadequate PLZ.
Materials and methods: Between January 2019 and December 2021, 93 patients with TBAD, with inadequate PLZ, who underwent TEVAR or hybrid procedure, were retrospectively evaluated in Beijing Anzhen hospital. Demographics, comorbidities, preoperative imaging features, periprocedural details, and follow-up outcomes were analyzed. Survival was analyzed according to Kaplan-Meier method.
Results: TEVAR procedures were performed on 41 patients (TEVAR group) and hybrid procedures on 52 patients (hybrid group). Early events, 30 day mortality, and all-cause mortality, were not significantly different between the 2 groups. However, patients receiving TEVAR had significantly shorter procedure time (p<0.001), hospital stay (p<0.001), and intensive care unit (ICU) stay (p=0.001) compared with those in the hybrid group. Patients receiving TEVAR had significantly lower midterm events (p=0.014) and re-intervention (p=0.015) compared with those in the hybrid group.
Conclusion: The study indicated that TEVAR with LSA revascularization for TBAD with inadequate PLZ is associated with a trend toward lower rates of midterm events, while the early and midterm mortalities were comparable with those in hybrid procedure.
Clinical impact: This study is novel as it compared the outcomes between thoracic endovascular aortic repair (TEVAR) and hybrid procedure in patients with type B aortic dissection (TBAD), with inadequate proximal landing zone, which has been rarely reported previously. We believe that our study makes a significant contribution to the literature because it is clinically relevant as it demonstrated that TEVAR with left subclavian artery (LSA) revascularization for TBAD with inadequate proximal landing zone is associated with a trend toward lower rates of mid-term events, while the early and mid-term mortalities were comparable with those in the hybrid procedure.
期刊介绍:
The Journal of Endovascular Therapy (formerly the Journal of Endovascular Surgery) was established in 1994 as a forum for all physicians, scientists, and allied healthcare professionals who are engaged or interested in peripheral endovascular techniques and technology. An official publication of the International Society of Endovascular Specialists (ISEVS), the Journal of Endovascular Therapy publishes peer-reviewed articles of interest to clinicians and researchers in the field of peripheral endovascular interventions.
