Significats de innominate vein en anglès

Background: Left innominate vein occlusion is a known complication of pacemaker and central venous catheter placement.

The left innominate vein crosses the artery in front from left to right, and must be drawn down.

Multiple attempts to percutaneously cross the left innominate vein were unsuccessful and the patient was referred for surgical intervention.

The presence of significant left innominate vein stenosis and tip location of the catheter was evaluated on chest computed tomography images.

Purpose:: To evaluate the effect of catheter diameter on left innominate vein stenosis in breast cancer patients after placement of totally implantable venous access ports.

Difference in the cumulative incidence of left innominate vein stenosis was statistically significant between the two groups (log rank test p-value: 0.002).

Contrast-enhanced CT demonstrated the lesion encroached and obstructed bilateral innominate veins and superior vena cava.

Diagnoses: The patient was diagnosed as stage-2 secondary lymphedema caused by idiopathic occlusion of the subclavian and innominate veins.
