Summary
Helical computed tomographic (CT) angiography effectively identifies arterial lesions in patients with penetrating neck injuries. This imaging technique serves as a reliable initial diagnostic tool for suspected vascular trauma.
Area of Science:
- Radiology
- Vascular Surgery
- Emergency Medicine
Background:
- Penetrating neck injuries pose a significant risk of arterial damage.
- Prompt and accurate diagnosis of arterial lesions is crucial for patient management and outcomes.
Purpose of the Study:
- To evaluate helical computed tomographic (CT) angiography as a primary diagnostic method for arterial injuries resulting from penetrating neck trauma.
Main Methods:
- A prospective study involving 175 patients with suspected neck arterial injuries.
- Helical CT angiography protocol included specific contrast administration and scanning parameters.
- Image interpretation was performed prospectively and retrospectively by radiologists.
Main Results:
- Helical CT angiography detected arterial lesions in 15.6% of patients, including occlusion, pseudoaneurysm, and arteriovenous fistulae.
- Two studies were inadequate, with conventional arteriography showing normal findings.
- Findings guided treatment decisions, including surgery, endovascular intervention, or observation.
Conclusions:
- Helical CT angiography is a suitable initial imaging modality for evaluating arterial injuries in penetrating neck trauma.
- The technique demonstrated good diagnostic performance in identifying vascular lesions.
