Summary
Forearm acute compartment syndrome (ACS) necessitates fasciotomy. Atraumatic ACS, often linked to comorbidities, carries a higher mortality risk, emphasizing the need for careful patient selection for primary closure.
Area of Science:
- Orthopedic Surgery
- Trauma Surgery
- Vascular Surgery
Background:
- Forearm acute compartment syndrome (ACS) is a surgical emergency requiring emergent fasciotomy to prevent irreversible damage.
- While trauma is the leading cause, atraumatic ACS necessitates a high index of suspicion.
- Understanding scenarios and outcomes of forearm fasciotomies is crucial for this rare diagnosis.
Purpose of the Study:
- To evaluate the scenarios and outcomes of forearm fasciotomies.
- To identify risk factors and predictors of mortality in forearm ACS.
- To assess the safety and efficacy of primary versus secondary closure techniques.
Main Methods:
- Retrospective review of patients undergoing forearm fasciotomy across two institutions from 2007 to 2022.
- Analysis of clinical outcomes, including mortality, reoperation rates, and complications.
- Comparison of outcomes between traumatic and atraumatic etiologies of ACS.
Main Results:
- Eighty-eight forearm fasciotomies were performed; trauma (48%) and arterial catheterization (13.6%) were most common.
- Mortality rate was 13.7% overall, significantly higher in atraumatic ACS (23% vs. 8%).
- Atraumatic ACS patients had more comorbidities; elevated lactate and potassium correlated with mortality.
Conclusions:
- Forearm ACS is a recognized risk of arterial catheterization.
- High mortality in forearm ACS, especially in comorbid patients, warrants careful counseling.
- Primary closure of fasciotomy sites in select cases can reduce secondary procedures.
