What is a CT guided needle lung biopsy?
A CT guided needle lung biopsy is a diagnostic procedure to see if there is a problem with in the lungs. During the procedure a tiny sample of tissue is taken from the lungs for analysis. A radiologist (x-ray doctor) uses the x-ray images produced from a CT (Computer Tomography) scan to guide the needle to the area where the biopsy will be taken.
Why do I need this procedure?
Your consultant has suggested that you should have a CT guided needle lung biopsy after discussion of your case with a radiologist. Your previous CT scan and other tests will have been reviewed and a biopsy has been recommended to try and clarify if there is a problem in the lung or not.
Your consultant will explain to you why they think you need this procedure and how it will benefit you. Once you have spoken to your consultant you can choose not to have the procedure, if you prefer.
What preparation should I make and what should I bring?
You can eat and drink normally on the day of the procedure. It is a long day and it is best to have a light breakfast before coming to hospital. Please bring an overnight bag with you to hospital just in case you need to stay the night and do bring any books, newspapers or media players that you might want.
It is best if someone else brings you to hospital and you should have someone available to take you home at the end of the afternoon. It is advised that you should have someone to stay with on the evening / night after the procedure.
Some patients require a covid-19 PCR swab a few days prior to the procedure. If this is required you will be informed by your consultant or specialist nurse. You will be asked to self-isolate after having the swab until the procedure.
Please continue taking any prescribed medication as normal
Please however inform the radiologist if you are taking any blood thinning medication. This includes (but not limited to) drugs such as Warfarin, Heparin, Dalteparin, Clopidogrel, Rivaroxaban, Dabigatran or Apixaban. Please ring your lung nurse specialist or contact your consultant via their secretary to discuss these medications if you have not been given specific instructions
Consent
We aim to make sure that every patient is fully informed about the risks and benefits of a procedure or treatment. Before you have the biopsy the radiologist will ask for your consent (permission) for the procedure to be carried out. Please make sure that you understand the risks and benefits of the procedure and that it has been explained to you in the detail you need. You will meet the radiologist shortly after your arrival in hospital to talk through the procedure. Once you have spoken to the radiologist you can choose not to have the procedure, if you prefer
What happens if I don’t have the procedure?
Your doctors will re-discuss the reasons for biopsy and also explore with you whether there are any alternatives to biopsy
What happens during a CT guided needle lung biopsy?
You will be asked to lie on the bed of the CT scanner and will be told the best position for taking the biopsy. A scan will be taken using a small metallic marker which is placed on the outside of your skin. This marker shows up in the scan images and means that we can decide the best place to take the biopsy. The skin at that site will be cleaned with antiseptic solution and numbed with a local anaesthetic. A biopsy needle will then be carefully inserted into the lung to take the tissue sample (biopsy). In order to take a good sample this part of the procedure may be repeated several times.
How long does the procedure take?
The procedure will take about 30-45 minutes. This includes the set-up time; the actual biopsy only usually takes a few minutes.
Will it hurt?
The local anaesthetic used to numb the area may sting for a few seconds. You may also be aware of pressure from the biopsy needles as it takes the sample.
What happens afterwards?
You will be taken back to the ward where you will rest for between four to six hours. You can eat and drink normally. You will have a chest x-ray one hour after the biopsy .Most patients can go home from mid to late afternoon. If there are any complications you may be asked to stay in hospital overnight.
When do I get my biopsy result?
The results of the biopsy will not be available immediately – they will be sent to the consultant in charge of your care. They will discuss the results with you at your next clinic appointment or by telephone if necessary.
What are the risks or complications of this procedure?
Sometimes a ‘pneumothorax’ or ‘collapsed lung’ can occur. This happens when air leaks from the lung and becomes trapped between the lung and the chest wall. If the air leak is large, a small tube (called a chest drain) may be inserted into the chest wall to suck out the trapped air. A small air leak with normally heal within a few days and does not need to be ‘drained’.
Some patients cough up blood after the procedure but this usually settles within 5 to 10 minutes.
The amount of radiation used is kept to a minimum and we strongly believe that the benefits of the procedure far outweigh any potential risk to your health.
There is the possibility that the results of the procedure will not provide your consultant with enough information to make a diagnosis. If this is the case it may be necessary to repeat the CT guided needle lung biopsy procedure to take a further biopsy of your lung tissue, or an alternative procedure called a bronchoscopy may be recommend.
The risks and complications of the procedure will be explained to you before you give your consent. Please ask any questions that you have.
Are there any alternatives to a CT guided needle lung biopsy?
It is sometimes possible to take a biopsy using a bronchoscope (a long narrow flexible tube) which is passed through the nose or mouth to reach the lungs. A biopsy can also be taken using a surgical procedure to reach the lung tissue. These alternatives are only suitable for certain patients. If you would like to know more please speak to your consultant.
