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 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...
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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
Aneurysm III: Interprofessional Care01:26

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

  • Neurology
  • Vascular Neurology
  • Neuroimaging

Background:

  • Persistent primitive trigeminal artery (PPTA) is a rare fetal vascular remnant.
  • Cerebral aneurysms are associated with various risk factors including hypertension and hemodynamic stress.
  • A known association exists between PPTA and cerebral aneurysms, suggesting shared etiologic factors.

Purpose of the Study:

  • To report a rare case of multiple anterior circulation cerebral aneurysms in a patient with incidentally detected PPTA.
  • To discuss the potential association between PPTA and the development of multiple cerebral aneurysms.

Main Methods:

  • Cerebral angiography was performed to investigate a ruptured aneurysm.
  • Diagnostic imaging identified the presence of a PPTA and multiple cerebral aneurysms.

Main Results:

  • The patient presented with a ruptured aneurysm and was incidentally found to have a PPTA.
  • Eight anterior circulation cerebral aneurysms were identified in the same patient.
  • This case represents a rare instance of aneurysm multiplicity in conjunction with PPTA.

Conclusions:

  • The co-occurrence of multiple cerebral aneurysms and PPTA is rare.
  • This case underscores the importance of considering PPTA in patients with multiple cerebral aneurysms.
  • Further research may elucidate the specific mechanisms linking PPTA to aneurysm formation.
