Abstract
OBJECTIVE: Less than 5% of deep vein thrombosis is due to thrombosis of the internal jugular vein. Genetic, malignant or inflammatory underlying diseases as well as insertion of venous catheters can be responsible for this pathology. Due to its rare occurrence, it is difficult to find systematic research about thrombosis of the internal jugular vein. METHODS: We performed a systematic analysis of present patient data from our ENT department with the electronic patient record considering the period from 2012-2017. Search terms were "thrombosis" and "jugular internal vein". We identified 41 patients with the requested diagnosis and performed further analysis of the cases. Internal jugular vein thrombosis was diagnosed in all patients using Duplex sonography and/or CT/MR angiography. RESULTS: Paraneoplastic thrombosis was found in 22/41 patients (54%), in 15 of the 22 (68%), the tumor was located in the ENT region. Two out of seven (29%) of the patients with tumor entities outside the head and neck region had thrombosis of the internal jugular vein as the first symptom of the disease. Another 14/41 patients (34%) had underlying inflammatory diseases - mostly streptococci-associated - for example a cervical abscess. In two patients, insertion of a central-venous catheter was causal, in three patients we could not find any reason for the development of thrombosis. CONCLUSION: To diagnose the rare and often asymptomatic thrombosis of the internal jugular vein, ultrasound of the cervical region should always include vascular imaging. Thrombosis of the internal jugular vein results mostly paraneoplastic or due to inflammation/abscess. It can be the first symptom of a malignant primary disease and always requires detailed diagnostic clarification. LEVEL OF EVIDENCE: 4.
