In summary, laparoscopy in PAT may have an important role in a selected subgroup of patients, with surgeon expertise also an important factor. Laparoscopy has screening, diagnostic and therapeutic roles, particularly where diaphragm injury is suspected. It is extremely sensitive in determining need for laparotomy but detects hollow visceral injuries less reliably. It has potential as a therapeutic tool in centres with appropriate expertise. The development of specific guidelines or protocols may increase the value of laparoscopy in trauma but this would require more evidence of a higher quality.

Staged repair appears both to protect against SCI and to enhance overall survival in extensive aortic repair.

Our series demonstrates the risk for late failure after EVAR is greater in patients who are younger and have chronic renal impairment at the time of implantation. Branched and fenestrated repair after failed EVAR is more complex than repair in the native aorta. More research is needed to identify patients at higher risk of failure after EVAR to prevent the need for rescue in the future.

Fenestrated/branched endovascular repair has a low incidence of sealing zone failure despite the increased complexity. However, development of a proximal endoleak destabilizes the repair and leads to increased mortality. Increasing complexity of design seems to improve the long-term outcome for patients requiring complex aortic repair.

Although they are technically feasible, both custom fenestrated endografts and chimney repairs for proximal thoracic disease involving the supra-aortic trunk vessels suffer from failures in intermediate follow-up, with a trend toward better long-term outcomes for custom devices. More work is needed to develop durable devices for this anatomic territory in the future.
