Summary
Abdominal vena cava (AVC) injuries, often caused by gunshot wounds, have a high mortality rate. Ligation of the AVC is a life-saving option for critically ill patients.
Area of Science:
- Trauma surgery
- Vascular surgery
- Surgical outcomes
Background:
- Abdominal vena cava (AVC) injuries present significant surgical challenges.
- High mortality rates are associated with traumatic AVC injuries.
- Understanding surgical management and outcomes is crucial for improving patient survival.
Purpose of the Study:
- To present the surgical management and outcomes of abdominal vena cava (AVC) injuries.
- To analyze demographic data, injury mechanisms, and associated factors.
- To evaluate the effectiveness of surgical interventions and identify predictors of mortality.
Main Methods:
- Retrospective record review of 48 patients with AVC injuries treated between 1999 and 2003.
- Data extraction included demographics, injury mechanism, surgical management, and outcomes.
- Patients with peritonitis or shock underwent emergency laparotomy.
Main Results:
- Gunshot wounds were the cause of 94% of AVC injuries.
- The overall mortality rate was 31% (15 deaths).
- Higher Injury Severity Score (ISS), preoperative hypotension, and blood transfusion requirements were significant predictors of mortality.
Conclusions:
- Abdominal vena cava injuries are associated with a high mortality rate.
- Ligation of the AVC is a feasible and life-saving surgical option in critically ill patients.
- Surgical site and management strategy did not significantly impact survival outcomes.
