CT Venography is an x-ray exam that uses a contrast material injection to show how blood flows through your veins. It may be used by your doctor to detect blood clots, identify a vein for use in a bypass procedure or dialysis access, or assess varicose veins prior to surgery.
Inform your doctor if you suspect you are pregnant and discuss any recent illnesses, medical conditions, medications you are taking, and allergies, particularly to iodinated contrast materials. You might be told not to eat or drink anything for several hours before your exam. Wear loose, comfortable clothing and leave your jewellery at home. You might be required to wear a gown.
A venogram is commonly used to assess the status of a vein or system of veins, detect blood clots within the veins, assess varicose veins prior to surgery, locate a vein in good enough condition to use for a bypass procedure or dialysis access, assist a physician in placing an IV or a medical device, such as a stent, in a vein, and guide treatment of diseased veins.
Aside from medications, your doctor may instruct you not to eat or drink anything for several hours prior to your procedure.
On the day of your procedure, the doctor may allow you to drink clear liquids.
Inform your doctor about all of the medications you are taking. Include any allergies, particularly to iodine contrast materials. Inform your doctor about any recent illnesses or medical conditions.
If a woman is pregnant, she should always notify her doctor and a gynaecologist. To avoid exposing the foetus to radiation, doctors will not perform many tests during pregnancy. If an x-ray is required,
X-rays, like light and radio waves, are forms of radiation. X-rays can penetrate most objects, including the human body. The x-ray beam is carefully aimed at the area of interest by the technologist. The machine emits a brief burst of radiation that travels through your body. The radiation creates an image, which is then recorded on photographic film or a special detector.
The x-rays are absorbed to varying degrees by different parts of the body. Dense bone absorbs the majority of the radiation, whereas soft tissue (muscle, fat, and organs) allows more of the x-rays to pass through. As a result, bones appear white on x-rays, soft tissue appears grey, and air appears black.
This test will most likely be performed as an outpatient procedure by your doctor.
A venogram is performed in the x-ray department of a hospital.
A venogram is typically performed in an x-ray department or an interventional radiology suite, also known as a special procedure’s suite.
You will be positioned on an x-ray table. The table may be set up in a standing position depending on the body part being examined (for example, the legs). You will be secured with safety straps if the table is repositioned during the procedure.
To inject the contrast agent, the physician will insert a needle or catheter into a vein. The location of the needle is determined by the area of your body where the veins are being evaluated. Several x-rays are taken as the contrast material flows through the veins being examined. You may be moved into various positions so that the x-rays can photograph your veins from various angles.
For the exam, you may need to remove some clothing and/or change into a gown. Remove any jewellery, removable dental appliances, eyeglasses, or metal objects or clothing that could interfere with the x-ray images.
A venogram can take anywhere from 30 to 90 minutes to complete. Fluids will be injected into your veins to flush out the contrast material. You will also be told to drink plenty of fluids the next day. After the catheter is removed, the IV site will be bandaged. Then you'll be watched for signs of complications, such as bleeding from the injection site, infection, or an allergic reaction.
