Veins of Head and Neck01:19

Veins of Head and Neck

6.9K
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...

Summary
This summary is machine-generated.

Bothrops snakebite, though typically causing local or distant hemorrhage, can rarely manifest as isolated intracranial bleeding. Prompt snake identification and medical care are crucial for managing this uncommon presentation.

Area of Science:

  • Toxicology
  • Neurology
  • Herpetology

Background:

  • Bothrops sp. venom exhibits proteolytic, hemorrhagic, and coagulant activities.
  • Clinical effects of Bothrops envenomation typically include ecchymosis and systemic hemorrhage.
  • Intracranial bleeding is an exceptionally rare manifestation of Bothrops snakebite.

Observation:

  • A case report of a 52-year-old male patient is presented.
  • The patient's sole symptom following a Bothrops sp. snakebite was intracranial bleeding.

Findings:

  • This case highlights that isolated intracranial bleeding can be the primary clinical sign of Bothrops snakebite.
  • The study underscores the infrequent occurrence of stroke-like presentations in Bothrops envenomation.

Implications:

  • Accurate identification of the venomous snake is critical for appropriate treatment.
  • Timely medical intervention is essential for improving outcomes in rare envenomation cases.
  • Clinicians should consider Bothrops snakebite in the differential diagnosis of spontaneous intracranial hemorrhage, especially in endemic areas.
