Excess mortality during the first year after arterial trauma

Area of Science:

• Vascular Surgery
• Trauma Care
• Public Health

Background:

• Existing arterial trauma research is primarily from outside Denmark.
• Findings from international studies may not be directly applicable to the Danish population.
• This study addresses the need for local data on arterial trauma outcomes.

Purpose of the Study:

• To investigate the long-term mortality rates of patients treated for arterial trauma at Odense University Hospital (OUH).
• To analyze the clinical characteristics of patients experiencing arterial trauma in a Danish setting.
• To provide data specific to the Danish healthcare context.

Main Methods:

• Historical cohort study of arterial trauma patients treated at OUH from 1990 to 2012.
• Utilized The Danish Vascular Registry and the Accident Analysis Group for patient data.
• Compared patient mortality with the general Danish population, matched for age, sex, and trauma date.

Main Results:

• Analyzed 231 patients with a median follow-up of 6.9 years.
• Traffic accidents were the most frequent cause of arterial trauma.
• First-year mortality rate ratio was significantly elevated at 15.34; a significant excess mortality persisted in the reconstructed subgroup (2.22) between years 1-5.

Conclusions:

• Arterial trauma patients exhibit increased mortality within the first year post-injury.
• Patients undergoing reconstructive arterial surgery following trauma show elevated long-term mortality, independent of initial trauma severity.
• The specific causes for this excess mortality (surgical factors, patient behavior, etc.) require further investigation.
