How It Is Done continued...
A needle biopsy is done by a doctor
who specializes in X-ray tests (radiologist) or a pulmonologist. Your
doctor will use a CT scan, ultrasound, or fluoroscopy to guide the biopsy
needle. The place where your doctor inserts the needle is cleaned first with an
antiseptic solution and draped with sterile towels. Your doctor will give you a
local anesthetic to keep you from feeling any pain
when the needle is inserted into your chest.
Your doctor will then
make a small puncture and ask you to hold your breath while the biopsy needle
is inserted into your lung. It is very important to avoid coughing or moving
while the needle is in your chest.
Once the desired amount of
tissue is collected, the needle is removed and a bandage is placed over the
puncture site. You will need to lie on your side for at least an hour to allow
the needle puncture site to seal up.
This biopsy takes about 30 to
60 minutes. You will be in the recovery room 1 to 2 hours. A chest X-ray is usually taken after a lung biopsy to
look for any problems related to the biopsy.
Open biopsy and video-assisted thoracoscopic surgery (VATS)
An open biopsy is done by a
chest (thoracic) surgeon or a
general surgeon. You will be given a
general anesthetic by an
anesthesiologist. There may also be one or more
assistants in the room.
You will be given a
sedative to help you relax about an hour before the
biopsy. You will have an
intravenous line (IV) placed in a vein. A tube will be
placed in your windpipe (trachea) and a machine will help you breathe.
An incision is made between the ribs over the area of lung where the
tissue sample is to be collected. A scope called a thoracoscope may be passed
through this incision to view the surface of the lung and to remove a sample of
lung tissue. A larger incision will be made if an open biopsy is needed to
remove a tissue sample.
