Veins of Head and Neck01:19

Veins of Head and Neck

1.8K
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 Neck

1.2K
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

638
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...

Esophageal Varices-I: Introduction01:24

Esophageal Varices-I: Introduction

111
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Area of Science:

  • Neurology
  • Vascular Medicine

Background:

  • Cavernous sinus thrombosis (CST) is a critical subtype of cerebral venous sinus thrombosis (CVST).
  • It can arise from both infectious (septic) and non-infectious (aseptic) causes.
  • The condition carries significant risks of morbidity and mortality.

Purpose of the Study:

  • To summarize the key aspects of cavernous sinus thrombosis.
  • To highlight the importance of rapid diagnosis and treatment.

Main Methods:

  • Literature review of septic and aseptic cavernous sinus thrombosis.
  • Analysis of incidence, treatment modalities, and outcomes.

Main Results:

  • The incidence of CST is estimated between 0.2 and 1.6 per 100,000 individuals.
  • Treatment options include antibiotics, anticoagulation, corticosteroids, and surgical interventions.
  • Current morbidity and mortality rates are approximately 15% and 11%, respectively.

Conclusions:

  • Cavernous sinus thrombosis is a life-threatening condition.
  • Timely identification and management are crucial for improving patient outcomes and survival rates.
