Discussing on the Aortic Coverage in Type B Aortic Dissection Treatment: A Comprehensive Scoping Review.

OBJECTIVE

The objective of this study is to investigate and address the question surrounding the determination of the optimal endograft length of coverage during TEVAR for type B aortic dissection (TBAD), with a particular emphasis on the distal landing zone (DLZ).

DATA SOURCES: MEDLINE, Scopus, and Web of Science databases were used.

METHODS

The PRISMA-ScR statement was followed.

RESULTS

Several variables can contribute to the length of coverage during TEVAR in TBAD patient. Baseline patient's characteristics, TBAD-related features, the type of endoprosthesis, and postoperative graft behaviour may contribute to the choice of coverage.

CONCLUSIONS

No robust data have been published regarding the optimal length of TEVAR. Therefore, reporting the percentage of covered aorta and improving computational studies should be valorised to improve postoperative outcomes.
