Computed tomography venography of the upper extremities - Using low dose bilateral contrast media injection in a patient with suspected venous thoracic outlet syndrome.

Venous thoracic outflow syndrome may occur as a result from compression of the subclavian and/or axillary vein and consequently, decreased blood flow and increased risk of thrombus formation. A previously healthy 34-year-old woman who, after intensive crossfit training, experienced sudden intense pain and swelling in her right upper arm was referred for computed tomography of her right upper arm and thoracic veins. The computed tomography was performed using bilateral injection of low dose, diluted contrast medium.

Single-phase bilateral low dose contrast medium injection for diagnosing occlusions of the thoracic venous system: a case report.

Occlusion of the thoracic venous system and/or occlusion of central venous catheters (CVC) of unknown cause can, in selected cases, require advanced imaging. Here, we describe a case study of a patient with a failing central dialysis catheter (CDC) which was diagnosed by computed tomography (CT) in connection with a single-phase bilateral low-dose contrast medium (CM) injection using only 3.6 g of iodine.
