Summary
Transverse-sigmoid sinus dural arteriovenous fistulae are abnormal brain vascular lesions. Understanding their venous drainage patterns is crucial for effective treatment, often involving endovascular therapy.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Transverse-sigmoid sinus dural arteriovenous fistulae (AVFs) are abnormal connections in the dura mater.
- These AVFs can cause diverse symptoms, from bruits to severe neurological deficits and hemorrhage.
Purpose of the Study:
- To review the anatomy, pathology, and management principles of transverse-sigmoid sinus dural AVFs.
- To focus on endovascular therapy, including indications, goals, and techniques.
Main Methods:
- Review of existing literature on transverse-sigmoid sinus dural AVFs.
- Analysis of angioarchitecture via angiography to determine venous drainage patterns.
- Discussion of endovascular and surgical treatment options.
Main Results:
- Venous drainage patterns significantly influence the clinical presentation and natural history of these AVFs.
- Endovascular therapy is a primary treatment modality, with specific indications and techniques discussed.
- Surgical treatment options are also considered.
Conclusions:
- Accurate diagnosis and understanding of venous drainage are essential for managing transverse-sigmoid sinus dural AVFs.
- Endovascular approaches offer effective treatment for many patients.
- A multidisciplinary approach considering angioarchitecture is key to successful management.

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...

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 middle...

01:17Veins
Veins are an integral part of our circulatory system, serving as the blood vessels that transport blood from all body regions to the heart. They are a network of hollow tubes that carry blood low in oxygen from the body's cells back to the heart for reoxygenation. Veins are crucial for maintaining the body's overall fluid balance and the continuous circulation of blood.

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...
01:22Portal Hypertension
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
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.
