A venogram is a diagnostic procedure that uses x-ray to take pictures of the veins (blood vessels) in a specific part of the body.
How Boston Children's Hospital approaches venography
Our pediatric interventional radiologists, the doctors who do the procedure, are highly trained and experienced in the advanced techniques for the diagnosis and treatment of certain disorders of blood vessels in children and infants.
In addition to the interventional radiologist, your child will be cared for by a team of anesthesiologists, nurse practitioners, nurses and technologists who specialize in caring for children undergoing interventional radiology procedures and treatments.
We perform venograms in our suite on the second floor of the hospital, which features three procedure rooms equipped with the latest imaging technology, a recovery area for patients who have received sedation or anesthesia and examining rooms for outpatient visits.
A venogram is an x-ray test that takes pictures of the veins (blood vessels) in a specific part of the body. It is performed by an interventional radiologist who injects contrast material into your child’s vein. X-ray images taken during the injection show the inside of the vein. The radiologist is then able to determine the location and nature of any abnormalities of the veins such as blockages, areas of enlargement or abnormal anatomy.
A venogram is needed to gather information about how your child’s blood vessels are working. Since venography is an invasive technique, it is recommended only in specific situations:
Venography may be done:
When you schedule the procedure, you will be given instructions regarding the time and place of arrival and dietary preparation.
No sedation or anesthesia is required for this test, unless it is combined with a therapeutic procedure.
When you arrive, please go to the Interventional Radiology check-in desk on the second floor of the main hospital. An patient experience representative will check in your child and verify his registration information.
Venography, when performed by properly trained and experienced physicians, is a safe procedure with no significant long term side effects. A small proportion of children may have an allergy to iodine based contrast agents. If this is known to be the case in your child, please inform the doctor or nurse prior to the procedure.
The procedure involves placement of a needle or catheter into a vein. The remainder of the examination is not painful, although your child must lie very still during the procedure.
Your child will be exposed to ionizing radiation (x-rays) during the procedure. We believe that the benefit to your child’s health outweighs the exposure that occurs during the percutaneous gastrostomy. Because children are more sensitive to radiation exposure than adults, we have been leaders in adjusting equipment and procedures to deliver the lowest possible dose to young patients.
Normally, you will learn the results from your referring physician. The results will be available immediately after the procedure, although, in complex situations, it may require a few hours to completely process and interpret the x-rays.
The future of pediatrics will be forged by thinking differently, breaking paradigms and joining together in a shared vision of tackling the toughest challenges before us.”
