Arteriography
The arterial system is an integral part of the circulatory system. Arterial problems are the underlying cause of many disease processes. Diseases of arteries include vascular malformation, atherosclerosis, stenosis or occlusion of vessels, bleeding from the GI tract, brain haemorrhage and coronary artery disease.
Arteriography is a special examination. It is done for the following reasons:
Diagnosis of vascular disorders
Interventional radiology procedures to
- Open up narrowed arteries e.g. in kidneys
- Occlude vascular malformation of brain
- Provide trans-arterial chemo/radiotherapy
In some cases, arteriography is done pre-operatively so that surgeons can plan their operations. This helps to reduce pain and the chance of bleeding during the operation.
- You will be admitted for preparation by your referring doctor.
- You will be asked to sign a consent form for the investigation.
- You should volunteer information to your doctor on your history of allergies to food and drugs, history of asthma, urtricaria, eczema and allergy to contrast media.
- You will be checked for any bleeding tendency.
- You need to fast for 4 to 6 hours before the examination.
- Your skin will be prepared around the puncture site.
- The examination involves the introduction of an angiocatheter through the skin to a relevant vessel. A local anaesthetic will be given prior to the puncture.
- The angiocatheter is usually introduced via the right femoral artery at the groin. Other sites may also be used, e.g. a brachial approach if both femoral pulses are absent.
- A thin catheter is then introduced through a needle and guide wire. When the angiocatheter reaches the target vessel, a suitable contrast is then injected and a number of X-ray images are recorded.
- You are advised to listen carefully to the instructions given by our staff. Sedation or general anaesthesia is usually used for paediatric patients. The examination might take two or more hours to finish.
- After the removal of catheter, the radiologist may need to press the puncture site for some time to stop bleeding.
- Overall complications are rare. After the procedure, you will be under observation in the ward. If you experience any problems, you should inform the attending doctor or nurse as soon as possible.
