Penetrating Aortic Injury due to Broken Ribs and Preventive Measures

We herein report two cases of patients that underwent prophylactic operations to prevent aortic injuries in association with fractured ribs. Penetrating aortic injuries induced by fractured ribs remain fatal. Prophylactic operations appear effective. However, the indication for such operations should be clarified further in the future.

Penetrating Abdominal Aortic Injury: Comparison of ACS-Verified Level-I and II Trauma Centers

OBJECTIVES

Penetrating abdominal aortic injury (PAAI) is a highly acute injury requiring prompt surgical management. When compared to surgeons at level-II trauma centers, surgeons at level-I trauma centers are more likely to take in-house call, and may more often be available within 15 minutes of patient arrival. Thus, we hypothesized that level-I trauma centers would have a lower mortality rate than level-II trauma centers in patients with PAAI.

METHODS

We queried the Trauma Quality Improvement Program database for patients with PAAI, and compared patients treated at American College of Surgeons (ACS)-verified level-I centers to those treated at ACS level-II centers.

RESULTS

PAAI was identified in 292 patients treated at level-I centers and 86 patients treated at level-II centers. Patients treated at the 2 center types had similar median age, injury severity scores and prevalence of diabetes, hypertension, and smoking (p > 0.05). There was no difference in the frequency of additional intra-abdominal vascular injuries (p > 0.05). Median time to hemorrhage control (level-I: 40.8 vs level-II: 49.2 minutes, p = 0.21) was similar between hospitals at the 2 trauma center levels. We found no difference in the total hospital length of stay or post-operative complications (p > 0.05). When controlling for covariates, we found no difference in the risk of mortality between ACS verified level-I and level-II trauma centers (OR:1.01, CI:0.28-2.64, p = 0.99).

CONCLUSION

Though the majority of PAAIs are treated at level-I trauma centers, we found no difference in the time to hemorrhage control, or the risk of mortality in those treated at level-I centers when compared to those treated at level-II trauma centers. This finding reinforces the ACS-verification process, which strives to achieve similar outcomes between level-I and level-II centers.
