Abstract PDF: Purpose
Managing hemodynamically unstable patients with pelvic fractures is highly challenging, particularly when vascular injuries are present, as these can significantly worsen prognosis. This study evaluated outcomes in patients with pelvic trauma and vascular injuries prior to the introduction of preperitoneal pelvic packing.
Methods
We retrospectively reviewed the medical records of 195 patients with pelvic injuries who presented to the emergency room of our hospital between May 2003 and August 2013.
Results
Among the 195 patients, 34 had vascular injuries and 161 had nonvascular injuries. The vascular injury group had significantly higher transfusion rates (82.4% vs. 11.8%, P<0.001) and required a greater mean number of packed red blood cell units than the nonvascular group (5.2±5.5 vs. 0.4±1.4, P<0.001). Subgroup analysis within the vascular injury cohort revealed significant differences between patients with venous phase extravasation (n=5) and those with isolated arterial phase extravasation (n=29) in median packed red blood cell units transfused (12.5 units vs. 3 units; P=0.014), cardiac arrest rate (80.0% vs. 10.3%, P=0.003), and mortality rate (60.0% vs. 10.3%, P=0.029). Notably, patients with isolated venous extravasation showed a significantly higher mortality rate compared to those with isolated arterial extravasation (100% vs. 10.3%, P=0.004).
Conclusions
Venous phase extravasation was associated with higher transfusion requirements, cardiac arrest incidence, and mortality compared to arterial extravasation.; Summary
