Summary
Lower extremity ischemic complications (ICs) after iliac artery injuries are linked to shock severity and pulselessness. Early recognition and fasciotomies are crucial to prevent amputations.
Area of Science:
- Vascular Surgery
- Trauma Surgery
- Ischemia Research
Background:
- Lower extremity ischemic complications (ICs) following iliac arterial injuries are a significant concern.
- Risk factors and outcomes for these complications remain under-addressed in existing literature.
Purpose of the Study:
- To identify risk factors associated with lower extremity ischemic complications after penetrating iliac arterial injuries.
- To compare outcomes between patients who develop ICs and those who do not.
Main Methods:
- Retrospective review of patients with penetrating iliac artery injuries over 15 years.
- Definition of IC as compartment syndrome with or without tissue loss.
- Comparison of demographics, shock severity, physical exam findings, and operative data between IC and non-IC groups.
Main Results:
- 17 out of 51 patients (33%) who underwent arterial reconstruction developed ICs.
- ICs significantly correlated with indicators of shock (pH, lactate, transfusion needs) and preoperative pulseless extremity.
- Delayed recognition of compartment syndrome led to a higher rate of amputations (8 vs. 0).
Conclusions:
- Shock severity and preoperative pulselessness are key predictors of ischemic complications after iliac arterial injury.
- Close monitoring of compartment pressures and prompt fasciotomies are essential for limb salvage.
