Permanent Hemodialysis Catheter Causing Superior Vena Cava Syndrome

Thrombogenic Catheter-Associated Superior Vena Cava Syndrome

Superior vena cava syndrome has historically been associated with malignancy. With the increasing use of indwelling central lines, catheters, and pacemakers in the past decade, there have been an increasing number of cases associated with thrombosis rather than by direct external compression. Patients presenting to the ED with an acute process of SVC syndrome need to be assessed in a timely fas...

Permanent catheter implantation via a persistent left superior vena cava.

A 48-year-old male with a history of benign nephrosclerosis and chronic haemodialysis for the last 6 years was admitted to our hospital. He was diagnosed with left radial arteriovenous fistula thrombosis. The right internal jugular vein (RIJV) was thrombosed (history of RIJV catheter) as confirmed by Doppler echography. A Dual-Cath (Medcomp) was inserted in the left jugular vein without complic...

Askin Tumor Presenting as Superior Vena Cava Syndrome

Superior vena cava syndrome.

Approximately 15,000 cases of superior vena cava (SVC) obstruction are diagnosed in the United States annually. Malignancies (primarily lung cancer) are the underlying cause of 80-85% of cases, leaving 15-20% caused by various benign conditions, including sclerosing mediastinitis (the diagnosis in our case). Thrombolytic therapy and major advances in vascular techniques in recent years have imp...

Superior Vena Cava Syndrome

1.1 Anatomy The superior vena cava (SVC) originates in the chest, behind the first right sternocostal articulation, from the confluence of two main collector vessels: the right and left brachiocephalic veins which receive the ipsilateral internal jugular and subclavian veins. It is located in the anterior mediastinum, on the right side. The internal jugular vein collects the blood from head and...
