The imaging of stab injuries

Area of Science:

• Trauma Surgery
• Diagnostic Imaging
• Emergency Medicine

Background:

• Penetrating trauma, particularly stab wounds, constitutes a significant portion of cases in trauma units.
• Established protocols guide the management of penetrating injuries.

Purpose of the Study:

• To review the current imaging modalities and their roles in evaluating penetrating trauma.
• To highlight the evolving use of computed tomography (CT) and other advanced imaging techniques.

Main Methods:

• Review of imaging utilization for penetrating trauma cases.
• Discussion of conventional and advanced imaging techniques including chest radiography, computed tomography (CT), multidetector CT angiography (MDCT), digital subtraction angiography (DSA), ultrasound (echocardiography), esophagoscopy, and bronchoscopy.

Main Results:

• Stab wounds comprise approximately 70.5% of penetrating injuries.
• Chest radiography remains a primary tool for thoracic injuries.
• Multidetector CT (MDCT) is increasingly adopted for hemodynamically stable patients.
• MDCT angiography is emerging as a faster alternative to digital subtraction angiography (DSA).
• Ultrasound is valuable for cardiac and aortic injuries, and detecting hemothoraces/pneumothoraces.
• Direct visualization (esophagoscopy, bronchoscopy) is crucial for esophageal and tracheal injuries.

Conclusions:

• Imaging plays a critical role in the comprehensive evaluation of penetrating trauma.
• The shift towards faster, less invasive imaging like MDCT reflects advancements in trauma care.
• A multimodal imaging approach, combining various techniques, is essential for accurate diagnosis and management.
