This review covers the angiographic appearance, variants, and embryologic origins of major visceral arteries. It also details collateral flow and splanchnic blood flow control mechanisms.

Area of Science:

  • Vascular anatomy
  • Embryology
  • Gastrointestinal physiology

Background:

  • The visceral arteries supply blood to the gastrointestinal tract and associated organs.
  • Understanding their anatomy and variations is crucial for diagnosing and treating mesenteric vascular diseases.
  • Mesenteric circulation is complex, involving intrinsic and extrinsic regulatory mechanisms.

Purpose of the Study:

  • To review the angiographic appearance of major visceral arteries.
  • To discuss common anatomical variants and their embryologic origins.
  • To explore sources of collateral flow and splanchnic blood flow control.

Main Methods:

  • Review of existing angiographic literature and anatomical studies.
  • Synthesis of embryologic principles related to visceral artery development.

  • Discussion of physiological mechanisms governing mesenteric circulation.

    • Main Results:

    • Detailed descriptions of the typical angiographic findings for celiac, superior mesenteric, and inferior mesenteric arteries.
    • Illustrations and explanations of common arterial variants.
    • Identification of key collateral pathways, such as the pancreaticoduodenal arcade and marginal artery of the colon.
    • Overview of sympathetic, parasympathetic, and local humoral control of splanchnic blood flow.

    Conclusions:

    • Familiarity with visceral artery anatomy, variants, and collateral pathways is essential for accurate angiographic interpretation.
    • Understanding splanchnic circulation physiology aids in diagnosing and managing mesenteric ischemia and other vascular conditions.
    • This review provides a comprehensive resource for clinicians and researchers in vascular and gastrointestinal imaging.
