Abdominal vascular emergencies: US and CT assessment

Area of Science:

• Radiology
• Vascular Surgery
• Emergency Medicine

Background:

• Vascular emergencies, encompassing traumatic and spontaneous injuries to arteries and veins, present significant life-threatening risks due to potential hypovolemic shock and end-organ ischemia.
• Prompt diagnosis and treatment are critical for managing these high-stakes conditions.
• Current diagnostic strategies for vascular injuries lack a firmly established approach, with unclear advantages of specific imaging techniques.

Purpose of the Study:

• To review and compare imaging modalities for diagnosing acute abdominal vascular emergencies.
• To focus on the utility of Ultrasound (US) and Computed Tomography (CT) in evaluating both traumatic and non-traumatic vascular injuries.

Main Methods:

• Review of existing literature on diagnostic imaging for abdominal vascular emergencies.
• Comparative analysis of Ultrasound (US) and Computed Tomography (CT) for evaluating arterial and venous injuries.
• Discussion of the accessibility, safety, accuracy, and clinical application of US and CT.

Main Results:

• Ultrasound (US) offers a safe, non-invasive, and accessible option for initial vascular assessment.
• Computed Tomography (CT), particularly with multiphasic imaging, demonstrates high accuracy in evaluating abdominal vascular injuries.
• CT is proposed as the primary imaging modality for managing acute abdominal vascular emergencies due to its comprehensive assessment capabilities.

Conclusions:

• Both Ultrasound and CT play roles in diagnosing vascular emergencies, but CT offers superior accuracy for abdominal cases.
• The choice of imaging modality should be guided by the specific clinical scenario and the need for detailed vascular assessment.
• Further research may refine the optimal diagnostic algorithms for various types of vascular emergencies.
