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...
The Arch of Aorta01:10

The Arch of Aorta

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...
Transient Ischemic Attack l: Introduction01:26

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
Cranial Nerves: Types Part I01:14

Cranial Nerves: Types Part I

Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

Area of Science:

  • Neuroanatomy
  • Embryology
  • Vascular Surgery

Background:

  • The trigeminal artery is the largest fetal carotid-basilar anastomotic artery, typically involuting after posterior communicating artery development.
  • Persistence into adulthood (persistent trigeminal artery or PTA) is uncommon, with unclear etiologies.
  • PTA can be associated with various cerebrovascular anomalies, necessitating detailed anatomical knowledge.

Purpose of the Study:

  • To review the embryology of the persistent trigeminal artery.
  • To describe the angiographic and microsurgical anatomy of PTA.
  • To discuss associated vascular anomalies and disorders.

Main Methods:

  • Review of existing literature on persistent trigeminal artery.
  • Analysis of anatomical and angiographic descriptions.
  • Synthesis of information on associated pathologies.

Main Results:

  • Detailed review of PTA embryology and its usual involution.
  • Description of diverse PTA configurations and their relationship to surrounding neurovascular structures.
  • Compilation of associated vascular anomalies such as aneurysms, arteriovenous malformations, and carotid-cavernous fistulae.

Conclusions:

  • A comprehensive understanding of PTA's embryology, anatomy, and associated pathologies is vital.
  • This knowledge is essential for informed therapeutic decisions and interventions.
  • Accurate anatomical and angiographic assessment guides management of PTA-related conditions.
