Summary
A rare case highlights that developmental venous anomalies, often linked with arteriovenous malformations, can be susceptible to blood flow changes, potentially causing complications like aphasia after treatment.
Area of Science:
- Neurovascular Medicine
- Vascular Malformations
- Neurosurgery
Background:
- Developmental venous anomalies (DVAs) are common congenital vascular malformations.
- Arteriovenous malformations (AVMs) are complex tangles of abnormal blood vessels.
- Co-occurrence of DVAs and AVMs is rare but clinically significant.
Observation:
- A 20-year-old male presented with seizures secondary to a left parietal AVM and a left frontal DVA.
- Both lesions shared a common draining vein, despite anatomical separation.
- Post-resection of the AVM, the patient developed progressive aphasia.
Findings:
- Neuroimaging revealed thrombosis in the draining vein of the DVA.
- Aphasia resolved with anticoagulant therapy using low molecular weight heparin.
- This suggests DVAs, despite normal drainage, are sensitive to hemodynamic shifts.
Implications:
- This case supports the understanding of DVA venous drainage patterns.
- It highlights the potential risk of thrombosis and neurological deficits in DVAs.
- Management of co-existing DVAs and AVMs requires careful consideration of venous hemodynamics.

01:19Veins of Head and Neck
1.0K
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...

01:28Esophageal Varices-II: Clinical Features and Management
31
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

01:24Esophageal Varices-I: Introduction
51
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

01:07Development of Blood Vessels
447
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

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...

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
