The Arch of Aorta01:10

The Arch of Aorta

797
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...

Glaucoma: Overview01:25

Glaucoma: Overview

652
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

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...

Arteries of the Head and Neck

1.5K
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...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Anastomoses01:19

Anastomoses

924
In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.
Arterial Anastomosis: These occur between arteries. They...

Area of Science:

  • Vascular Surgery
  • Neurosurgery
  • Neuroradiology

Background:

  • Aneurysms of the ophthalmic artery (OphA) are rare, distinct from more common internal carotid artery (ICA) aneurysms.
  • These lesions are frequently associated with trauma or flow-related conditions like arteriovenous fistulas.
  • This study focuses on the clinical and radiological characteristics of proper ophthalmic artery aneurysms (POAAs).

Purpose of the Study:

  • To investigate the clinical and radiological features of proper ophthalmic artery aneurysms (POAAs).
  • To identify common and unique characteristics of POAAs in a series of patients.
  • To inform the management strategies for these rare aneurysms.

Main Methods:

  • Retrospective review of patients diagnosed with POAAs between January 2018 and November 2021.
  • Analysis of clinical data and diagnostic cerebral angiogram (DCA) findings.
  • Correlation of POAAs with associated cerebrovascular pathologies, particularly trauma and fistulas.

Main Results:

  • Five POAAs were identified in four patients.
  • Three patients had POAAs secondary to traumatic brain injury.
  • Associated pathologies included carotid-cavernous-sinus fistula, ethmoidal dAVF, and a history of embolization for dAVF.

Conclusions:

  • Proper ophthalmic artery aneurysms (POAAs) present management challenges due to risks of visual compromise and hemorrhage.
  • Diagnostic cerebral angiography (DCA) is crucial for detecting associated cerebrovascular conditions.
  • Observation may be suitable for POAAs without associated pathology or symptoms.
