Insights
This study on central vessel trauma (CVT) found a 70% survival rate in 30 patients. Key factors influencing mortality include cardiac arrest, emergency thoracotomy, descending thoracic aorta cross-clamping duration, and prolonged shock.
Area of Science:
- Vascular Surgery
- Trauma Management
- Surgical Critical Care
Background:
- Central vessel trauma (CVT) presents significant management challenges.
- Major arteries and veins in the chest, neck, and abdomen are susceptible to injury.
- Effective treatment requires specialized surgical expertise and critical care.
Purpose of the Study:
- To review outcomes and identify prognostic factors in patients treated for central vessel trauma (CVT).
- To analyze surgical access strategies for challenging anatomical locations.
- To determine factors contributing to mortality in CVT patients.
Main Methods:
- Retrospective review of 30 patients treated for CVT over a 24-month period.
- Analysis of injuries to major thoracic, cervical, and abdominal vessels (excluding infrarenal aorta).
- Evaluation of surgical approaches, complications, and survival data.
Main Results:
- Overall survival rate was 70% (21 out of 30 patients).
- Mortality was associated with cardiac arrest, emergency thoracotomy, prolonged aortic cross-clamping (>1 hour), and persistent shock.
- Surgical access to difficult areas like the thoracic outlet, suprarenal aorta, and inferior vena cava was detailed.
Conclusions:
- Central vessel trauma management requires careful consideration of patient stability and surgical timing.
- Prognosis is poor in cases of intraoperative cardiac arrest, high-risk emergency procedures, and prolonged hemodynamic compromise.
- Optimizing surgical strategy and critical care is crucial for improving outcomes in CVT.
Abstract:
During a 24 month period, 30 patients were treated for central vessel trauma (CVT). Injured vessels included all of the major arteries and veins in the chesk, neck and abdomen except the infrarenal aorta. Overall survival was 70 per cent. Experience with specific injuries is reviewed with commentary on surgical access to difficult areas including the thoracic outlet, suprarenal aorta and inferior vena cava. Common factors in the nine deaths are reviewed with the findings that cardiac arrest at any time during pre- or intraoperative management is uniformly lethal; emergency thoracotomy for control of bleeding carries an expectedly high mortality; cross-clamping of the descending thoracic aorta to control hemoperitoneum has a limit of tolerance of about one hour, and prolonged shock, whether compensated or profound is poorly tolerated and is associated with a high mortality.
