Angiogram

An angiogram is a minimally invasive test that uses a special contrast solution (dye) and imaging technology to map the arterior veins in a part of your child's body. A cerebral angiogram maps the blood vessels in the brain. It is performed by a specially trained doctor called an interventional radiologist or a neurointerventional radiologist.

我应该如何为血管造影准备我的孩子？

Explain to your child in simple terms why the test is needed and what will happen. You can say that you will be close by and that she may bring a favorite toy or blanket into the procedure room.

有些孩子需要来Perioperative Care Coordination Clinicfor lab tests and exams by a nurse, anesthesiologist, and nurse practitioner. Please allow two to four hours for the preoperative visit.

血管造影前会发生什么？

A staff person from the hospital will call you a few days before the procedure with preparation instructions that will include dietary restrictions necessary for sedation or anesthesia. It is very important that you follow all of these instructions, or the procedure may need to be rescheduled. When you arrive at the hospital:

• 介入放射科医生或神经皮层将与您交谈，并要求您签署同意书。（您必须是您孩子的法律监护人签署此表格。如果您是法律守护者而不是父母，则必须将文书工作显示出现在法定监护人的证明。）
• 你的孩子会变成一件医院礼服。
• A nurse or anesthesiologist may start an intravenous (IV) line.
• Once your child is asleep, you will be escorted to a special waiting area.

血管造型机中会发生什么？

The radiology technologist will clean your child's groin with a special liquid that helps prevent infection.

Through a tiny incision, the interventional radiologist will insert a small needle into the appropriate blood vessel, usually at the crease of the hip. This will provide access for insertion of a long, thin tube (the catheter) into the vessel.

UnderX射线指导，放射科医生将导管引导到所研究的血管，然后将通过导管注入特殊的对比溶液，使得她可以更清晰地看到孩子的血管。

Several x-rays may be taken. If awake, your child needs to hold her breath and keep very still during this part of the procedure.

When the angiogram is finished, the radiologist removes the catheters and applies a bandage.

您的孩子被转移到恢复室，您可以在那里加入她。护士将密切关注你的孩子四到六个小时，你的孩子需要在那时不弯曲腿部而需要躺着。

The radiologist will speak with you after the procedure and explain the findings and results.

Are angiograms safe?

血管造影被认为是轻微的外科手术。血管造影通常是安全的，但与任何手术程序一样，带有一些并发症的风险。医生将在要求同意该程序之前解释潜在的副作用和并发症。

During angiography, your child will be exposed to ionizing radiation (x-rays). While we strive to minimize exposure to x-rays, we believe that the benefit to your child's health outweighs the exposure that occurs during the angiogram. 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.

How Boston Children’s Hospital approaches angiograms

Angiography and cerebral angiography in children is different than in adults, because children have smaller and more delicate blood vessels. Our physicians are highly trained in using the specialized techniques and small catheters necessary for performing angiograms in children.

In addition to the 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 angiograms in a suite, 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.
