Insights

High riding jugular bulb (HJB) is a vascular abnormality. This study found HJB in 42.8% of pediatric patients, with prevalence increasing with age.

Area of Science:

  • Vascular abnormalities
  • Pediatric imaging
  • Anatomy

Background:

  • High riding jugular bulb (HJB) is a vascular anomaly where the jugular bulb is abnormally positioned superiorly.
  • Understanding the prevalence and characteristics of HJB is crucial for interpreting cranial imaging in children.

Purpose of the Study:

  • To determine the frequency of high riding jugular bulb (HJB) in pediatric patients undergoing cranial computed tomography (CT).
  • To analyze the association between HJB and patient demographics, particularly age.

Main Methods:

  • Retrospective analysis of cranial CT scans from 194 pediatric patients.
  • Recorded patient demographics, jugular bulb (JB) diameters, and presence/laterality of HJB.
  • Statistical analysis included Shapiro-Wilk, Mann-Whitney U, Pearson's chi-square, and Fisher's exact tests.

Main Results:

  • High riding jugular bulb (HJB) was identified in 42.8% of the 194 pediatric patients evaluated.
  • Children with HJB were significantly older than those without HJB (P=0.029).
  • The prevalence of HJB increased with age, from 0% in newborns to 50% in children over 24 months.

Conclusions:

  • High riding jugular bulb (HJB) is a common finding in pediatric cranial CT, with a prevalence of 42.8%.
  • HJB prevalence increases with age, suggesting a developmental component.
  • The jugular bulb is identifiable across all pediatric age groups, with the earliest detection of HJB at eight months.

Veins of Head and Neck01:19

Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Arteries of the Head and Neck01:26

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Assessment of the Cardiovascular System II: Inspection01:29

Assessment of the Cardiovascular System II: Inspection

Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.
