fine needle aspiration or core biopsy
What is a Fine Needle Aspiration or Core Biopsy?
This procedure is designed to obtained a small specimen of tissue to send to a Pathologist, in order to determine if there is an abnormality. This is done under imaging guidance, either ultrasound or CT, to ensure the specimen is taken from the correct location and to minimise any risk of injury to sensitive tissues. This keeps any potential complications as low as possible.
The procedure will be explained in detail by the specialist and a consent form signed. The procedure will be carried out with as much care as possible, using best sterile technique to minimise risk of infection. Local anaesthetic will be administered when necessary to make the procedure as comfortable as possible.
It is common for 2 or 3 passes with the needle to be taken at the one sitting, to make sure adequate tissue is obtained.
Preparation:
- All patient X-rays to be brought with them
- Nil by mouth for 4 hours. Medications can be taken with a sip of water
- If you are diabetic, talk to your doctor if adjustment to your medications may be needed.
- If on Heparin, cease 4 hours prior to procedure.
- Cease Warfarin and Aspirin 1 week prior to the appointment
- Cease Plavix 5 days prior to procedure.
- Cease Clexane 24 hours prior to appointment
- Recent blood results FBC and COAGs within last 6 weeks
- For some procedures, a set of baseline observations will be taken.
Post-Procedure Care:
- Some procedures require you to stay for observation for up to 2 hours.
- If you have a lung biopsy, there will be a chest X-ray at 30 minutes - 1 hour.
- If you have a renal biopsy, you may have a check ultrasound at 1-2 hours.
