When investigation for vascular disease is undertaken the tests used may be divided into non-invasive vascular tests and invasive vascular tests. Non- invasive tests are in general sensitive to the presence of vascular disease but may not be accurate with respect to the degree of vascular pathology. Invasive testing is also sensitive to the presence of vascular disease but very much more anatomically accurate than physiologically specific with respect to vascular diseases. In general , non- invasive testing is performed initially because of the lower risk of complications from these tests.
Patients who are found to have vascular disease on non -invasive testing can be more adequately assessed and may or may not need to proceed to further and riskier invasive testing.
Neither invasive nor non- invasive testing should be used to assess patients in the absence of a good clinical patient history and well conducted physical examination. Attempts to do this outside appropriate clinical context often result in significant misinterpretation of test results. Frequently the outcome of this approach is to cause the patient significant unnecessary anxiety and can even result in submitting patients to unnecessary invasive testing and inappropriate intervention.
Ultrasonography is a non-invasive method of assessing the arterial and venous circulation in various regions of the body. These tests are performed by Dr Englund in his rooms personally. Equipment available is a Semens S2000 Duplex ultrasound system, Parkes Flowlab and Medsonics Duplex scanner. This practice is registered with medicare as a recognised diagnostic imaging practice.Read More
Digital Subtraction Angiography
Digital Subtraction Angiography is an invasive, but very accurate, method of assessing and diagnosing vascular disease. This method involves an injection of radio contrast agent into the blood vessels to be examined. Usually, this test is performed before any intervention can be undertaken. It is conducted as an out patient under local anaesthetic. The main risks relate to the injection and the injection site and the administration of contrast agent which may have side affects relating to the kidneys or allergy.
