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...
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...

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...
Traumatic Brain Injury l: Introduction01:28

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...

Area of Science:

  • Trauma surgery
  • Vascular surgery
  • Orthopedic surgery

Background:

  • Bilateral carotid artery dissection is a rare but life-threatening consequence of blunt trauma.
  • Early diagnosis and appropriate management are crucial for preventing severe outcomes.

Observation:

  • A collision patient presented with bilateral asymptomatic carotid artery dissections.
  • The patient also sustained multiple pelvic and extremity fractures.

Findings:

  • The patient was successfully managed with aspirin for the carotid artery dissections.
  • Orthopedic fractures were treated with open reduction and internal fixation without complications.

Implications:

  • Carotid artery dissections are increasingly identified in blunt trauma cases.
  • Management requires balancing anticoagulation/antiplatelet therapy with hemostasis needs.
  • Screening for carotid artery dissection is recommended in patients with relevant injury mechanisms.
