颅内静脉畸形

诊断

由于颅内静脉畸形可能不会引发症状，因此医务人员可能会在检查其他神经系统问题时发现您存在此状况。

您可能需要接受以下影像学检查以诊断其他神经系统状况：

• CT 扫描。CT 扫描可创建一系列 X 线图像，从而生成血管和大脑的详细横截面图像。在某些情况下，医生会将染料注入静脉，以更详细地评估大脑组织或血管（CT 血管造影或 CT 静脉造影）。
• 磁共振成像（MRI）。电磁波和无线电波可创建血管和脑部的详细三维图像。在某些情况下，医生会将造影剂注入静脉，以便以不同的方式观察脑组织，并评估您的血管。
• MRA。磁共振血管造影术是另一类重点关注动脉的 MRI。MRA 可显示脑血管的血流情况。
• MRV。磁共振静脉造影是一类重点关注静脉的 MRI。

治疗

医生通常不治疗颅内静脉畸形，因其很少引起症状。如果您出现不相关的症状，例如头痛，医生可能会给您开药。

患有颅内静脉畸形的人可能会出现癫痫发作或脑出血（脑溢血），但这种情况很少见。这些通常是由于伴有血管畸形的其他静脉畸形所致。医生通常用药物治疗癫痫发作。

有些出血需要手术，但是许多出血可以通过医疗管理和住院观察来治疗。

准备您的预约

Make an appointment with a doctor or other healthcare professional if you have any symptoms that worry you.

If your healthcare professional thinks that you might have an intracranial venous malformation, you may be referred to a doctor who specializes in diseases that affect the brain and nervous system. This type of doctor is called a neurologist or neurosurgeon.

Because appointments can be brief, it's a good idea to be prepared. Here's some information to help you get ready.

What you can do

• Be aware of any pre-appointment restrictions. At the time you make the appointment, be sure to ask if there's anything you need to do in advance, such as restrict your diet.
• Write down symptoms you're experiencing, including any that may not seem related to the reason for which you scheduled the appointment.
• Write down important personal information, including major stresses or recent life changes.
• Make a list of all medicines, vitamins or supplements you're taking and the doses.
• Take a family member or friend along. Sometimes it can be very hard to remember all the information provided during an appointment. Someone who goes with you may remember something that you missed or forgot.
• Write down questions to ask your healthcare team.

Your time with your healthcare team is limited, so preparing a list of questions can help you make the most of your time together. List your questions from most important to least important in case time runs out. For intracranial venous malformations, some basic questions to ask include:

• What are other possible causes for my symptoms?
• What tests are needed to confirm the diagnosis?
• What are my treatment options and the pros and cons for each?
• What results can I expect?
• What kind of follow-up should I expect?

Don't hesitate to ask other questions.

What to expect from your doctor

Be prepared to answer questions, such as:

• When did your symptoms begin?
• Have your symptoms been continuous or occasional?
• How severe are your symptoms?
• What, if anything, seems to improve your symptoms?
• What, if anything, appears to worsen your symptoms?
