  2. Dialysis catheter - Wikipedia

    en.wikipedia.org/wiki/Dialysis_catheter

    A dialysis catheter is a catheter used for exchanging blood to and from a hemodialysis machine and a patient. The dialysis catheter contains two lumens : venous and arterial . Although both lumens are in the vein, the "arterial" lumen, like natural arteries, carries blood away from the heart, while the "venous" lumen returns blood towards the ...

  3. Central venous catheter - Wikipedia

    en.wikipedia.org/wiki/Central_venous_catheter

    Insertion is a surgical procedure, in which the catheter is tunneled subcutaneously under the skin in the chest area before it enters the SVC. Commonly used tunneled catheters include Hickman, and Groshong, or Broviac catheters and may be referred to by these names as well. A tunneled catheter may remain inserted for months to years.

  4. Groshong line - Wikipedia

    en.wikipedia.org/wiki/Groshong_line

    Groshongs may be left in place for extended periods and are used when long-term intravenous therapy is needed, such as for chemotherapy.Similar to the Hickman line, the tip of the catheter is in the superior vena cava, and the catheter is tunneled under the skin to an incision on the chest wall, where the distal end of the catheter exits the body.

  5. Vascular access for chemotherapy - Wikipedia

    en.wikipedia.org/wiki/Vascular_access_for...

    Tunneled catheters have multiple channels called lumens which lay exposed on the surface of the skin. These lumens are the access points when the catheter is used. Tunneled catheters can be single, double, or triple lumened. Removal of a tunneled catheter is a simple procedure requiring only local anesthetic. A bandage is applied to the site to ...

  6. Hickman line - Wikipedia

    en.wikipedia.org/wiki/Hickman_line

    A Hickman line two-lumen catheter inserted on the patient's left side. Scars at the base of the neck indicate the venotomy site and insertion point into the left jugular vein . A Hickman line is a central venous catheter most often used for the administration of chemotherapy or other medications, as well as for the withdrawal of blood for analysis.

  7. Vascular access - Wikipedia

    en.wikipedia.org/wiki/Vascular_access

    Catheter access, sometimes called a CVC (central venous catheter), consists of a plastic catheter with two lumens (or occasionally two separate catheters) which is inserted into a large vein (usually the vena cava, via the internal jugular vein or the femoral vein) to allow large flows of blood to be withdrawn from one lumen, to enter the dialysis circuit, and to be returned via the other lumen.

  8. Port (medicine) - Wikipedia

    en.wikipedia.org/wiki/Port_(medicine)

    A port catheter is passed through the tunnel where one end is attached to the chemport and another end is left hanging out near the IJV insertion site. The length of the hanging port catheter should be about 16 to 17 cm (or can be measured from the IJV insertion site until 2 cm below the sternal angle where the right atrium should begin).

  9. Interventional radiology - Wikipedia

    en.wikipedia.org/wiki/Interventional_radiology

    Permanent hemodialysis catheters are longer overall but a segment is tunneled through the skin of the chest, which lets the catheter lie flat and lowers the risk of infection. Central venous access refers to a variety of intravenous catheters placed in patients requiring certain long-term medications.
