Iatrogenic and noniatrogenic arterial trauma: a comparative study

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Trauma Surgery

Background:

• Arterial trauma can be iatrogenic (caused by medical interventions) or non-iatrogenic.
• Understanding the differences in outcomes and causes is crucial for improving patient safety.
• Iatrogenic injuries often result from catheterizations or surgical procedures.

Purpose of the Study:

• To compare the incidence, causes, and outcomes of iatrogenic versus non-iatrogenic arterial injuries.
• To assess the preventability of iatrogenic arterial trauma.
• To identify factors contributing to patient morbidity and mortality in both injury types.

Main Methods:

• Retrospective analysis of 22 patients with iatrogenic arterial trauma (Group A) and 43 with non-iatrogenic arterial injury (Group B) over six years.
• Data collected included injury cause, associated injuries, surgical interventions, hemorrhage, mortality, and permanent disability.
• Independent review by two vascular surgeons assessed the appropriateness of techniques in iatrogenic cases.

Main Results:

• Hemorrhage was significantly more common in non-iatrogenic injuries (Group B) (p < 0.001).
• Permanent disability was more frequent in Group B due to associated injuries (p < 0.05).
• Mortality rates were similar between groups (14% vs. 9%); bypass surgery trends did not differ significantly.

Conclusions:

• Iatrogenic arterial trauma is a significant concern, with potentially avoidable causes identified.
• While non-iatrogenic injuries present with more acute complications like hemorrhage, iatrogenic injuries contribute to long-term disability.
• The incidence of iatrogenic arterial trauma is considered 'reducible', emphasizing the need for improved procedural techniques and vigilance.
