Summary
Cervical artery dissections, often caused by arterial wall tears, are increasingly diagnosed. Treatment typically involves antithrombotic medications, with a low recurrence rate for stroke or dissection.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Arterial dissections in the head and neck are increasingly recognized due to improved diagnostics and clinical awareness.
- These dissections stem from arterial wall stretching and tearing, leading to intramural hematoma.
- Symptoms commonly include headache and pain, with specific types causing ischemia, aneurysms, or hemorrhage.
Purpose of the Study:
- To review the current understanding of cervical artery dissections.
- To highlight diagnostic modalities and treatment approaches.
Main Methods:
- Review of clinical features and diagnostic imaging techniques for arterial dissections.
- Discussion of current treatment strategies and recurrence rates.
Main Results:
- Conventional angiography is optimal for visualization, though CT/MR angiography, MRI, and ultrasound are also effective.
- Subintimal dissections primarily cause brain and eye ischemia.
- Subadventitial dissections can lead to aneurysms, pseudoaneurysms, and subarachnoid hemorrhage.
Conclusions:
- Antithrombotic medications are the mainstay of treatment, despite a lack of randomized trial data.
- The recurrence rate of infarction or dissection following initial events is notably low.

01:10The 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.

01:26Arteries 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...

01:18Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
01:19Anastomoses
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.

01:20Anatomy of the Brain: Major Regions
The brain is the most complex organ in the human body. It consists of four main parts: the cerebrum, diencephalon, cerebellum, and brainstem.
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect various areas...

01:19Veins of Head and Neck
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...
