Intra-abdominal vascular trauma-a need for prompt operation
Insights
Prompt surgical intervention is crucial for treating major abdominal vascular injuries. Delays in obtaining vascular control, especially due to prolonged emergency department evaluations, significantly increase mortality from hemorrhage.
Area of Science:
- Trauma Surgery
- Vascular Surgery
- Emergency Medicine
Background:
- Major abdominal vascular injuries present a high mortality rate.
- Hemorrhage and hypovolemic shock are primary causes of death.
- Timely surgical intervention is critical for patient survival.
Purpose of the Study:
- To analyze the outcomes of patients with major abdominal vascular injuries.
- To identify factors influencing mortality in these patients.
- To emphasize the importance of prompt operative vascular control.
Main Methods:
- Retrospective review of 81 patients with major abdominal vascular injuries.
- Analysis of injury mechanisms, associated injuries, and number of vessels injured.
- Correlation of these factors with mortality rates and causes of death.
Main Results:
- Overall mortality was 35.8% (29/81 patients).
- Massive blood loss and hypovolemic shock were the main causes of death (70% of deaths).
- Mortality increased significantly with the number of associated nonvascular injuries and injured vessels.
Conclusions:
- Prompt operative intervention to achieve vascular control is the most critical factor in treating intra-abdominal vascular injuries.
- Prolonged diagnostic evaluations in the Emergency Department delay essential surgical care and increase mortality.
- Resuscitation should occur in the operating room when possible to expedite vascular control.
Abstract:
Prompt operative intervention to obtain vascular control is the most important factor in the treatment of intra-abdominal vascular injuries. In 81 patients with major abdominal vascular injuries, bullet wounds were the cause of injury in 51, stab wounds in 12, blunt trauma in ten, shot gun in seven, and one was an iatrogenic injury from insertion of a dialysis catheter. Twenty-nine of 81 patients died (35.8%). Twenty patients (70%) died of massive blood loss at operation or in the early postoperative period. Hypovolemic shock was the predominant distinguishing feature in the mortality group. The mortality rate increased with the number of associated nonvascular injuries, ranging from 20% in patients without associated injuries to 100% in patients with five or more associated injuries. The mortality rate was also increased with the number of vessels injured, ranging form 20% with one or two injured vessels to 100% with four or more. Late deaths occurred in nine patients and were most commonly related to the complications of hypovolemic shock. In hospital settings where patients can be resuscitated in the operating room, prolonged stay in the Emergency Department for diagnostic and laboratory evaluation only delays the operative vascular control of exsanguinating hemorrhage.
