Summary
Fewer cerebral deep medullary veins (DMVs) correlate with poorer white matter integrity and increased brain atrophy. This suggests small venules disease contributes to neurodegeneration.
Area of Science:
- Neurology
- Radiology
- Neuroimaging
Background:
- Cerebral small venules disease is implicated in brain lesions.
- The role of deep medullary veins (DMVs) in white matter integrity and atrophy requires further investigation.
Purpose of the Study:
- To investigate the association between cerebral deep medullary veins (DMVs) and white matter microstructural integrity.
- To examine the relationship between DMVs and regional brain atrophy using MRI.
Main Methods:
- Utilized susceptibility-weighted imaging to identify DMVs in 979 community-based participants.
- Assessed brain structural measurements including gray matter and hippocampus volumes.
- Evaluated diffusion tensor imaging metrics to analyze white matter integrity.
Main Results:
- A lower number of DMVs was associated with reduced white matter integrity (lower fractional anisotropy, higher mean diffusivity).
- Fewer DMVs correlated significantly with lower gray matter and hippocampal fractions.
- DMV reduction was linked to cortical atrophy in the occipital, temporal, hippocampus, and frontal lobes.
Conclusions:
- Cerebral small venules disease, indicated by reduced DMVs, plays a role in brain parenchymal lesions.
- DMV integrity is associated with white matter microstructure and regional brain atrophy, suggesting a link to neurodegenerative processes.

01:19Veins of Head and Neck
3.3K
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...

01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
64
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

01:18Anatomy of the Brain: Ventricles
5.7K
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.

01:11Overview of Systemic Veins

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

01:30Venous Thrombosis I: Introduction
72
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

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...
