Iatrogenic occlusion of bilateral jugular veins, subclavian vein, and superior vena cava after repeated jugular cannulation associated with Arnold-Chiari malformation: Successful endovascular treatment.

ABSTRACT

An Arnold-Chiari malformation is a congenital central nervous system defect. Raised intracranial pressure is commonly observed, and posterior decompression neurosurgery is the treatment of choice. We describe a patient with iatrogenic occlusion of bilateral jugular veins, subclavian vein, and superior vena cava resulting from repeated central venous cannulations. Because of venous hypertension, the patient suffered from neurologic symptoms headaches, vision disturbances, and marked head edema. Two stents were used to recanalize the right internal jugular vein and superior vena cava. Symptoms subsided, and the patient returned to work. During 24-month follow-up, stents were patent. The patient remains symptom free and continues working.
