Treatment of idiopathic internal jugular vein thrombosis in a healthy woman with enoxaparin and rivaroxiban: Case report and literature narrative review.

Introduction: Venous thrombosis is a medical condition that occurs when a blood clot forms in a vein. These clots usually develop in the lower leg, thigh, or pelvis but can also occur in the arm. It is essential to know about Venous thrombosis because it can happen to anybody and cause severe illness and disability. Fortunately, if the diagnosis is early, the outcomes will be excellent. However, idiopathic or spontaneous internal jugular vein thrombosis is a rare but potentially fatal condition. Method: here, we presented a rare case of Internal jugular vein thrombosis (IJVT) and reviewed the literature on cases of IJVT to describe clinical features, associated risk factors, possible complications, ways of investigations, and outcomes. Results: Among 57 cases (56 in the literature plus our case), 25 patients out of 57 had a chief complaint of neck swelling, and only five complained of neck pain; on the other hand, four patients were asymptomatic. Thirty-five patients had a risk factor of developing thrombosis, 19 patients had a malignancy, and 22 did not have an obvious risk factor. To diagnose IJVT, ultrasound alone was used in 11 patients, Ct alone was used in 13 patients, and a combination of CT and ultrasound was used in 21 patients. Conclusion: IJVT thrombosis is a rare condition, but its diagnosis requires reasonable radiological and laboratory investigations; early treatment is warranted to avoid fetal complications.
