Abstract

Background:

The risk of internal jugular vein thrombosis is a concern when using the internal jugular vein as a recipient vein in microvascular head and neck reconstruction. This study aimed to investigate the incidence of internal jugular vein thrombosis within 2 weeks of microvascular head and neck reconstruction using computed tomographic angiography.

Methods:

This retrospective study included 103 patients who underwent postoperative contrast-enhanced computed tomography within 2 weeks of microvascular head and neck reconstruction. The incidence, characteristics, treatment course, outcomes, and risk factors of internal jugular vein thrombosis were investigated.

Results:

Internal jugular vein thrombosis was found in five cases (4.7%). In three of these cases (2.8%), internal jugular vein thrombosis occurred on the side of the microvascular anastomosis, and all of them were completely obstructed; however, the flaps survived without vascular compromise. No variables were considered risk factors for internal jugular vein thrombosis.

Conclusions:

The incidence of internal jugular vein thrombosis after microvascular head and neck reconstruction was lower than previously reported. Most cases of internal jugular vein thrombosis are assumed to be subclinical and do not lead to anastomotic failure. It remains unclear whether asymptomatic internal jugular vein thrombosis on the anastomotic side should be treated.

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...

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...

Prevalence and Incidence

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Internal Energy

Internal Energy

The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial.

Internal Energy

Internal Energy

The internal energy of a thermodynamic system is the sum of the kinetic and potential energies of all the molecules or entities in the system. The kinetic energy of an individual molecule includes contributions due to its rotation and vibration, as well as its translational energy. The potential energy is associated only with the interactions between one molecule and the other molecules of the system. Neither the system's location nor its motion is of any consequence as far as the internal...

Internal Receptors

Internal Receptors

Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.
