“…Just as with the ~25I-fibrinogen test, it is insensitive in cases with pelvic vein thrombosis, and inflammation may produce false-positive results. This makes the positive predictive value rather low, whereas the negative predictive value is higher [87][88][89][90]. It can, therefore, be looked on as a simple screening test to exclude the need for phlebography in negative cases.…”

A wide range of clinical symptoms and signs are observed with venous thrombosis. Nonetheless, clinical diagnosis has been found to be unreliable and accurate diagnostic methods must be used before potent therapy such as anticoagulation is instituted, since the complications of treatment themselves can be life-threatening. Phlebography is still the basic reference for evaluation of deep venous disease. While it is felt to be the most accurate, there are still limitations relative to difficulty in separating acute from chronic disease, and in obtaining adequate contrast in certain veins such as calf muscles and in the larger intraabdominal veins. Moreover, it is an uncomfortable invasive test, not without complications of its own. The 125I-fibrinogen uptake test is an excellent test for screening for forming thrombi. The sensitivity of this test is high, particularly in the detection of small calf vein thrombi. The primary drawbacks of this technique are that it is falsely positive in cases where there has been bleeding, inflammation, gross edema, arthritis, or leg ulceration. It is not accurate above mid-thigh because of the high blood flow at the level of the groin and pelvis. Radioactive labeled plasmin which will adhere to the surface of recently formed thrombi can also be used for diagnosis. The limitations are a very short half-life of the radioactive label so that repeated investigation of a patient cannot be performed unless new injections are given. The diagnostic accuracy is comparable to that of radioactive labeled fibrinogen and has the same advantages and disadvantages. Plethysmographic techniques have been used with various modifications.(ABSTRACT TRUNCATED AT 250 WORDS)

“…Besides that, production of vasoactive amines may enhance local arterial circulation. 61 The diagnosis of DVT by infrared thermography is mainly qualitative. Visible asymmetry with a diffused area of an enhanced heat emission over calf or thigh is suggestive of DVT (Figure 3).…”

Venous thromboembolism is a serious medical, social, and economic problem. A number of treatment options exist to decrease mortality and morbidity in patients with deep vein thrombosis (DVT). An accurate and timely diagnosis of this condition is important to improve immediate and long-term prognosis. The standard diagnostic algorithm implying assessment of the clinical probability of the disease, d-dimer test, and venous duplex ultrasound is not optimal. Infrared thermography is a relatively new diagnostic modality under clinical investigation for various medical conditions. This study aims to review the published evidence on infrared thermography as a possible alternative tool in DVT diagnosis. The authors conclude that infrared thermography is still an experimental diagnostic tool for patients with DVT, and requires more clinical research evidence to support theoretical advantages and suggest a possible clinical application.

99mTc-plasmin test in deep vein thrombosis of the leg

et al. 1985

A 99mTc-plasmin test and phlebography were performed on 45 consecutive unselected patients with suspected deep vein thrombosis of the leg. Phlebography showed thrombosis in 15 cases. In fourteen of these patients there was a positive result in the plasmin test. Eleven other patients had a positive plasmin test result as well. The most common causes for a false-positive result in the plasmin test in the diagnosis of deep vein thrombosis were acute inflammatory disease and disturbance in venous flow without fresh thrombosis. The sensitivity of the plasmin test in the diagnosis of deep vein thrombosis was 93% and the specificity was 63%. It is concluded that the plasmin test can be used for the screening of deep vein thrombosis.
