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.
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.
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.
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 ...
In hemodialysis, vascular access is used to remove the patient's blood so that it can be filtered through the dialyzer. Three primary methods are used to gain access to the blood: an intravenous catheter, an arteriovenous fistula (AV) or a synthetic graft. In the latter two, needles are used to puncture the graft or fistula each time dialysis ...
A Hickman line, a type of tunneled catheter, inserted through the skin at the chest and tunneled to insert into the jugular vein in the throat. A tunneled line is a type of central access which is inserted under the skin, and then travels a significant distance through surrounding tissue before reaching and penetrating the central vein.
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 ...
Examples include Hickman catheters, peripherally inserted central cathethers (or PICCs), tunneled small bore central venous catheters, and mediports. These lines differ in where they are inserted but are all placed under imaging guidance and adjusted so the end of the catheter sits in the vena cava adjacent to the heart.
