Imaging for Hepatic Vascular Injury from Blunt Trauma in Children-Nine Cases Report

Area of Science:

• Pediatric Traumatology
• Vascular Surgery
• Diagnostic Imaging

Background:

• Hepatic vascular injury (HVI) is an infrequent yet significant complication of blunt abdominal trauma (BAT) in pediatric patients.
• Accurate diagnosis and timely management of HVI are critically dependent on advanced imaging modalities.

Purpose of the Study:

• To evaluate the incidence and characteristics of hepatic vascular injuries in children following blunt abdominal trauma.
• To emphasize the essential role of imaging in the diagnosis and management of HVI in pediatric patients.

Main Methods:

• A retrospective review of pediatric patients diagnosed with liver injuries between 2000 and 2007.
• Analysis of 25 cases of liver injuries, with a specific focus on the 9 identified cases of HVI.
• Utilized sonography, duplex sonography, and computed tomography for diagnostic evaluation.

Main Results:

• Hepatic vascular injury was identified in 36% (9 out of 25) of pediatric liver injury cases.
• The study recorded various HVI types, including vein injuries, traumatic hepatic artery pseudoaneurysms, and arteriovenous fistulas.
• The male to female ratio was 1.25, with a mean age of 7.88 years.

Conclusions:

• Hepatic vascular injuries represent a substantial proportion (36%) of pediatric liver injuries.
• These injuries carry a high mortality rate, underscoring the necessity for systematic and rapid detection and treatment.
• Imaging plays a pivotal dual role in both diagnosing and guiding the therapeutic approach for HVI.
