The Arch of Aorta01:10

The Arch of Aorta

654
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

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...

Abdominal Aorta

746
Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Area of Science:

  • Neuroscience
  • Radiology
  • Anatomy

Background:

  • Cerebral artery variations are crucial for understanding neurological conditions and surgical planning.
  • The distal anterior cerebral artery (DACA) and its branches exhibit significant anatomical variability.
  • Limited data exists on DACA variants within the Greek population.

Purpose of the Study:

  • To determine the prevalence of DACA variants in a Greek cohort.
  • To classify ACA configurations and identify ACA patterns like bihemispheric, median, and azygos.
  • To investigate the presence and gender distribution of the callosomarginal artery (CMA).

Main Methods:

  • Retrospective analysis of 456 patients undergoing bilateral carotid and vertebral digital subtraction angiography (DSA).
cerebral vessels
  • Inclusion of patients with clear visualization of anterior and posterior circulations.
  • Utilized 2D/3D DSA and MR/CT angiography for detailed 3D reconstruction and ACA classification.

    • Main Results:

    • A typical DACA pattern was observed in 81.8% of patients.
    • Bihemispheric, median, and azygos ACA patterns occurred in 14.5%, 2.2%, and 1.5% respectively.
    • The CMA was present in 90.4% of hemispheres, with a trend towards male predominance and significantly higher frequency in males' left hemispheres.

    Conclusions:

    • This study establishes baseline DACA variant rates in the Greek population.
    • Observed gender differences in CMA prevalence suggest potential sex-based morphological variations in cerebral vasculature.
    • Findings enhance understanding of vascular anatomy for clinical and surgical applications.
