Trust but Verify? Utility of Intraoperative Angiography After Revascularization for Vascular Trauma.
Lehrman et al., Am Surg 2023
DOI: 10.1177/00031348231220593
Study Summary:
A retrospective analysis of the PROOVIT database from 2013 to 2021 was conducted to evaluate the utility of intraoperative angiography (IA) in trauma patients who had undergone open brachial or femoral artery revascularization. The study included 185 patients, predominantly male (86.5%), with a median age of 29, an injury severity score of 12, and a systolic blood pressure of 117. IA was performed in 39% of the cases, with 14% requiring immediate revision and 8% needing vascular reoperation during their hospital stay.
Key Findings:
- Patients who underwent IA and lacked a palpable pulse post-repair were significantly more likely to need immediate revision surgery (22% vs 9%, P = .013).
- There was no significant difference in the likelihood of requiring reoperation between patients who underwent IA and those who did not (7% vs 9%, P = .613).
Importance:
The study suggests that IA is a valuable tool in the management of vascular extremity trauma, leading to a higher rate of immediate revision surgeries. This underscores the importance of training in angiographic techniques for surgeons handling vascular trauma.
Contribution to Literature:
This research provides evidence supporting the use of IA in trauma surgery, particularly when a pulse is not palpable after vascular repair. It emphasizes the need for proficiency in angiography among trauma surgeons to improve surgical outcomes.
