CT SCAN OF PERIPHERAL VENOGRAM

CT scan of peripheral venogram is a radiology examination that employs an X-ray machine and a computer to obtain photographs of the veins in the distal parts of the body, like the limbs and feet. This examination is performed to assess and evaluate problems that may alter blood circulation within these body parts.  

What is a CT scan of Peripheral Venogram? 

CT scan of peripheral venogram is the method of examination that employs X-rays and computers to analyse the veins located in the more remote segments of the body. During the examination, a contrast medium is placed into the vein of the affected extremity so that the veins may be visualized better. The affected region is then photographed using X-rays, which are processed into detailed images of the veins cross-sectionally. 

Types of CT scan of Peripheral Venogram 

Different Forms of CT scans of Peripheral Venogram include: 

• Non-Contrast CT scan: This type is used to assess the shape and size of the veins and omits the use of contrast agents. 
• Contrast Enhanced CT scan: This type uses contrast agents to emphasize the veins for enhanced visualization.  
• CT Venography: This scan combines X rays with computer technology to give detailed images of the veins. 

While conducting the CT scanning procedure for the peripheral venogram, a medical practitioner will focus on the following parameters: 

• The shape and size of the veins 
• Considering the narrowing or blockage of the veins 
• Any existing blood clots or deep vein thrombosis 
• Presence of any spider vertebrates and varicose veins 
• Any existing inflammation or infection in the veins 

Patient specific variables that may require changes include age, medical history, or the presence of metal implants. 

A CT scan of peripheral venogram is normally recommended:  

• To identify blood clots or DVT.  
• To assess varicose veins or spider veins.  
• For monitoring the stage of peripheral vascular disease.  
• For treatment planning concerning blood flow in the body’s periphery. 

When and Who Needs to Take a CT scan of Peripheral Venogram? 

A CT scan of peripheral venogram is often suggested for patients that report: 

• Pain, swelling, or any warmth in the limbs such as the arms and legs 
• Spider veins or varicose veins 
• Deep vein thrombosis (DVT) or blood clots 
• Infectious or inflammatory conditions of the veins 
• Narrowing or blockages of the veins 

The following conditions in the list are usually accompanied by some risk factors or a history:  

• Blood clot and DVT 
• Varicose veins or spider veins 
• Tumours or cancer that may affect circulation 
• Infection or inflammation of the veins 

Benefits of Taking the Test

The venogram provides unique advantages such as:  

• The creation of very precise images of the veins.  
• Diagnosing DVT and blood clots in their early stages.  
• Diagnosing and assessing varicose and spider veins and treating them.  
• Assessing the stage of peripheral vascular disease. 

Illnesses Diagnosed with CT scan of Peripheral Venogram

The following conditions can be detected using a CT scan of peripheral venogram:  

• Deep vein thrombosis (DVT) or blood clot.  
• Varicose veins and spider veins.  
• Peripheral artery disease.  
• Vein infections or inflammatory diseases.  
• Blood flow cancers or tumours. 

Prior to taking the test, the patient should:  

• Dress in soft, relaxed clothing.  
• Take off any metallic adornments or pieces of clothing. 
• Avoid eating or drinking for a few hours before undertaking the test. 
• Inform his/her doctor about any medicines they are having or any other medical concerns which may be pertinent. 

Pre-requisites 

Prior to the test, the patient may need to carry out the following: 

• Give consent by signing a form. 
• Submit medical history alongside relevant medications being used. 
• Undergo a medical physical examination. 

Best time to do the Ct scan of peripheral Venogram 

The medical professional may ultimately decide the best time for their patient, but the exam is preferably done in the morning/early afternoon. 

Eligibility 

The CT scan of peripheral venogram would commonly be recommended on patients who are at risk or have had a history of any medical condition that would disturb blood flow to the peripheral regions of the body parts. 

Procedure for taking the CT scan of peripheral venogram 

The procedure would typically take about 30 – 60 minutes to complete. the following steps should be completed during this period:  

1. The patient is placed on a bed which is then placed into the CT scanner.  
2. Contrast medium injection is administered to a vein located in the limb affected. 
3. X-rays from the CT scanner are used to take images of that region. 
4. The patient is told to stay quiet and keep from breathing for a few seconds.  
5. The CT scanner transforms the data into detailed images of the cross-sectional anatomy of the veins. 

Caution Before Taking the Test 

Patients must communicate any medications being taken or any health issues they have to the doctor prior to the exam. Patients must also refrain from eating or drinking for several hours prior to the test.
