Chronic indwelling central venous catheters can result in formation of fibrin sheaths increasing risk of occlusion, thrombosis and infection. Endovascular infection of right-sided heart structures ...

In the best of circumstances, the puncture is made in direct line with the venous anastomosis so that the diagnostic catheter can be converted to a vascular sheath for subsequent intervention (Figure ...

The venous sheath was then replaced by a bidirectionally steerable sheath, whereupon one end of the catheter system was successfully mobilized into the inferior vena cava with the angulated tip of ...

CT scan confirmed perforation of the mid innominate vein. Venogram of the left innominate vein was obtained through an 8 Fr sheath, placed in the left cephalic vein to ascertain the site of ...

A 6F shuttle sheath (Cook Medical, Bloomington, Indiana, USA) was then placed in the dominant internal jugular vein. A 0.027 inch Renegade microcatheter (Stryker, Kalamazoo, Michigan, USA) was placed ...

At the end of the sheath, the infusate can leak into the vein and cause chemical irritation. In some cases, the sheath may even force the infusate to leak at the insertion site. When this occurs ...

Previous treatment modalities include medical management, therapeutic lumbar puncture and optic nerve sheath fenestration. They have proved to be effective but carry high rates of symptom recurrence ...

This approach can also be used when there is excessive venous scar or due to operator preference. A retrospective comparison of the femoral approach with laser sheath for extraction of older leads ...

In the transfemoral approach, the pacing lead is grabbed with a deflecting guide wire or retriever through a long sheath inserted from the femoral vein.7,11 The proximal end of the lead is pulled down ...
