What is the risk associated with an internal jugular vein (IJV) thrombosis?

From the Guidelines

Internal jugular vein thrombosis is a serious and potentially life-threatening condition that requires immediate medical attention, with the primary danger being the risk of pulmonary embolism, which can cause respiratory distress or death, as noted in studies such as 1. The condition can lead to septic emboli if infected, spreading infection throughout the body. Key risk factors for internal jugular vein thrombosis include:

• Central venous catheter placement
• Intravenous drug use
• Deep neck infections
• Hypercoagulable states Treatment typically involves anticoagulation therapy with medications such as low molecular weight heparin (enoxaparin 1mg/kg twice daily) or direct oral anticoagulants (apixaban 10mg twice daily for 7 days, then 5mg twice daily) for at least 3-6 months, as seen in 1. In severe cases with large clots or significant symptoms, thrombolytic therapy may be considered. Patients should be hospitalized initially for monitoring and treatment initiation. Early recognition and treatment are crucial to prevent complications, and patients should be educated about the signs of worsening, including increased neck pain, swelling, difficulty breathing, or chest pain, which warrant immediate medical evaluation, as discussed in 1. It is essential to note that the risk of pulmonary embolism and other complications can be mitigated with prompt and appropriate treatment, highlighting the importance of timely medical intervention, as emphasized in 1.

From the Research

Internal Jugular Thrombus: Risks and Complications

• Internal jugular vein thrombosis (IJVT) is a serious event with potentially fatal outcomes, including pulmonary embolism, sepsis, and intracranial propagation of the thrombus 2.
• The clinical presentation of IJVT may be vague or misleading, with patients possibly experiencing neck pain, headache, swelling, erythema, and a palpable cord sign beneath the sternocleidomastoid muscle, frequently associated with fever 3.
• IJVT can be caused by various factors, including malignant tumors, deep neck space infections, and cervical intravenous drug abuse 2.

Diagnosis and Treatment

• Imaging procedures such as sonography, computed tomography, magnetic resonance imaging, and magnetic resonance venography are used to diagnose IJVT 2.
• There is no standardized treatment regimen for patients with IJVT, but therapy with intravenous antibiotics and systemic anticoagulation is recommended 2.
• Ligation or resection of the internal jugular vein is reserved for patients who develop complications despite adequate medical therapy 2.

Risk of Pulmonary Embolism

• The risk of pulmonary embolism (PE) in patients with IJVT is a concern, but the association between IJVT and PE has not been clearly characterized 4.
• Studies have shown that the overall observed mortality attributed to PE in patients with IJVT is low, and the use of anticoagulation did not reduce mortality in those with isolated IJVT 4, 5.
• The presence of a central venous catheter is a significant risk factor for acute upper torso deep venous thrombosis (UTDVT), which includes IJVT 5.

Outcome and Risk Factors

• Internal jugular vein thrombosis can lead to high morbidity related to pulmonary embolism and post-thrombotic syndrome, particularly in patients with secondary deep venous thrombosis 6.
• Significant factors for internal jugular vein thrombosis include older patients, female gender, and ovarian hyperstimulation syndrome 6.
• Bilateral internal jugular vein thrombosis is a significant risk indicator of malignancy 6.
