Aortic Arch Repair Using Open and Hybrid Techniques: A Systematic Review.

Early surgical intervention is critical for treatment of aortic arch aneurysms and dissections, but limited comprehensive data exist to define the optimal approach for surgical management with respect to postoperative outcomes. We conducted a systematic review of the 2 most common surgical approaches-total arch replacement and hybrid arch repair. We referenced the electronic PubMed database reporting on outcomes for these surgical approaches from inception to June 2022. Our initial search query returned a total of 2,517 records. All records were independently screened for adherence to our inclusion criteria and a total of 12 retrospective cohort studies were identified as appropriate for inclusion. Across the included studies, a total of 618 patients underwent hybrid repair, as compared to 2,104 patients who underwent total arch replacement. We found that most of the literature supported the findings of similar rates of permanent neurologic dysfunction, acute kidney injury, and short-term mortality between approaches and higher postoperative reintervention rates following hybrid repair. Reported outcomes of studies included in this review often conflicted regarding midterm and long-term survival, as well as hospital and intensive care unit length of stay following open and hybrid repair. Future studies should address midterm and long-term survival with a prospective study design.
