Veins of Head and Neck

Veins 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...

The Arch of Aorta

The 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.
Encircling the heart, the coronary arteries form a ring-like structure before...

Arteries of the Head and Neck

Arteries 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...

Venous Thrombosis I: Introduction

Venous Thrombosis I: Introduction

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...

Overview of Systemic Veins

Overview 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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

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...

Area of Science:

Neurology

Vascular Malformations

Background:

Arteriovenous malformations (AVMs) in the medulla oblongata present significant treatment challenges due to the critical location.
Venous varices associated with AVMs can increase complexity and bleeding risk.

Purpose of the Study:

To report a case of a medulla oblongata AVM with a venous varix.
To describe the successful multimodal treatment strategy employed.
To highlight potential improvements in patient outcomes for such complex cases.

Main Methods:

Endovascular obstruction of the feeding artery (possibly anterior spinal artery branch from the right distal vertebral artery).
Stereotactic radiosurgery for residual abnormal vasculature.
Clinical and radiological follow-up.

Main Results:

Successful obstruction of the feeding artery led to the disappearance of the venous varix.
Stereotactic radiosurgery effectively treated the remaining AVM.
The patient experienced a positive outcome following the combined treatment approach.

Conclusions:

A combined approach of arterial obstruction and stereotactic radiosurgery can be effective for treating complex medulla oblongata AVMs with venous varices.
This strategy offers a promising avenue for improving patient outcomes in challenging neurovascular cases.
