Purpose:
To compare the clinical outcomes and trends of arterial embolization (AE) versus laparotomy which are used in the management of pelvic trauma.
Materials And Methods:
Adult patients with pelvic injuries were identified using the National Trauma Data Bank (NTDB) from 2007 to 2015. Patients with non-pelvic life-threatening injuries were excluded. Patients were grouped in operatively managed pelvic ring injuries, laparotomy ± fixation, AE ± fixation, and laparotomy and AE ± fixation. Using a linear mixed regression and logistic regression models, hospital length of stay (LOS), ICU days, ventilator days, and mortality for different therapies were compared. A propensity score weighting method was used to further eliminate treatment selection bias in the study sample and compare the outcomes between AE and laparotomy.
Results:
Of 7473 pelvic trauma patients, 1226 (16.4%) patients were only operatively managed. 3730 patients (49.9%) underwent laparotomy, 2136 underwent AE (28.6%), and 381 (5.1%) patients underwent both laparotomy and AE. The year of injury, patient age, gender, race, severity of injury and presence of shock were found to be predictors of receipt of different therapies (P < 0.001 for all). When correcting for these confounding factors, the mortality rate was lower in the AE group compared to the laparotomy group 6.6% vs. 20.6% (P < 0.001). Additionally, LOS and ICU days were shorter for the AE group than the laparotomy group (P < 0.001).
Conclusion:
AE in patients with pelvic injuries is associated with lower mortality, as well as shorter LOS and ICU stays compared to laparotomy.
