  Catheter, hemodialysis



Catheter, hemodialysis

   A venous catheter used for hemodialysis (dialysis of the blood). A hemodialysis catheter is a type of central venous catheter. It may be inserted into the subclavian, internal jugular, or femoral veins. Subclavian catheters generally may be used for 2 to 6 weeks. Hemodialysis catheters are often for relatively short-term use because of an acute need for dialysis or because chronic dialysis is just starting.

Venous
Having to do with a vein.

Catheter
A thin, flexible tube that carries fluids into or out of the body.

Hemodialysis
A mechanical method of cleaning the blood for people who have kidney disease. See also: Dialysis.

Central
In anatomy and medicine (as elsewhere), central is the opposite of "peripheral" which means away from the center.

Jugular
Of the neck or throat, as in jugular veins.

Femoral
Having to do with the femur.

Veins
Blood vessels that carry blood from the arms, legs, head and body organs back to the heart.

Acute
1. Of short course. 2. Severe, but of a short duration. Not chronic.

Dialysis

Once there, the catheter is purposely positioned in a small branch of the pulmonary artery. Then a pressure called the pulmonary wedge pressure is measured in front of the temporarily inflated and wedged balloon.

Cancer, Hodgkin disease (adult)
A type of lymphoma (cancer of the lymphatic system). The most common symptom of Hodgkin disease is a painless swelling in the lymph nodes in the neck, underarm, or groin. Hodgkin disease is diagnosed when abnormal tissue is detected by a pathologist after a biopsy of an enlarged lymph node. Treatment usually includes radiation therapy or chemotherapy. Regular follow-up examinations are important after treatment for Hodgkin disease. Patients treated for Hodgkin disease have an increased risk of developing other types of cancer later in life, especially leukemia.
