Abstract:
A 21-year-old woman presented to the hospital for right lower neck pain. The patient reported that the pain started after she attempted to stretch backward. In addition, she complained of pain and swelling over her right upper arm which started a day after the neck pain started. On admission, vitals were within normal limits. Physical examination was positive for erythema, swelling and tenderness in the upper right arm and right subclavicular region. CT angiography of the neck and CT of the cervical spine were unremarkable. Complete blood count and a complete metabolic panel were within normal range. Ultrasound venous of the right upper extremity showed a large echogenic thrombus of the right subclavian vein (figure 1). Given the above findings, further detailed history was obtained. The patient denied a family history of coagulation disorder. However, she admitted to being on oral contraceptive pills. Coagulation studies showed a normal protein S activity along with a negative factor V Leiden, anticardiolipin and prothrombin G20210A mutation. Antithrombin III level was slightly lower. The patient was subsequently placed on a heparin infusion and was scheduled to undergo thrombolysis. Venography performed before …Keywords:

The efficacy of Tc-99m RBC venography has been demonstrated with respect to the study of lower extremity deep venous thrombosis. A case is presented where Tc-99m RBC venography was used to study the upper as well as lower extremities in a patient with upper extremity deep venous thrombosis (DVT) who was found to have pulmonary embolism.

Both legs of 52 patients, in whom deep thrombosis was clinically suspected in one leg, were investigated. Out of the 52 legs used as a control, without suspected deep venous thrombosis, two were found to have deep venous thrombosis. Laboratory findings revealed that deep venous thrombosis was not present in 25% of the cases suspected. The patients in this group did not require venogram and were not treated. Nineteen suspected legs (36.5%) were proved negative not only by the laboratory method but also by venography.

OBJECTIVES. Deep venous thrombosis in children is frequently related to central venous lines. Study objectives were to determine objectively the incidence of deep venous thrombosis in children with short-term central venous lines and to assess the diagnostic value of venography, venous ultrasonography, and echocardiography, in a prospective cohort study. METHODS. Consecutive children with congenital heart disease requiring short-term central venous lines in the upper venous system were screened systematically for deep venous thrombosis by using venography, venous ultrasonography, and echocardiography, according to standardized protocols. RESULTS. The study population consisted of 90 children (median age: 2.7 years; range: birth to 18 years). Most central venous lines (97%) were located in the jugular veins. The overall incidence of deep venous thrombosis was 25 cases (28%) among 90 children. Venography identified deep venous thrombosis located in the subclavian and central veins but missed most deep venous thrombosis in the jugular veins. Venous ultrasonography had good sensitivity in the jugular veins but did not detect deep venous thrombosis in central veins. Echocardiography detected only 1 case of central deep venous thrombosis. CONCLUSIONS. The incidence of central venous line-related deep venous thrombosis in children with short-term central venous lines is high and comparable to reports for children with long-term central venous lines. Sensitivities of venography, venous ultrasonography, and echocardiography in children vary depending on the affected venous segment. A combination of diagnostic tests is required for sensitive detection of central venous line-related deep venous thrombosis in the upper venous system.

Preliminary reports have described the use of MR imaging for the detection of deep venous thrombosis. However, no prospective study comparing MR imaging with contrast venography (the gold standard) has been reported. Accordingly, we performed a prospective, blinded study of the efficacy of MR imaging in 61 consecutive patients with clinically suspected deep venous thrombosis. In cases of disagreement, additional testing was performed to determine the diagnosis. From June 1991 to February 1992, 61 patients with clinically suspected deep venous thrombosis were examined with venography and MR imaging. The average time between studies was 3 hr. In 21 of the 61 patients, the final diagnosis was deep venous thrombosis. For detection of deep venous thrombosis in the pelvis, the sensitivity of MR imaging was 100% (9/9) with a 95% confidence interval of 72-100% and the specificity was 95% (52/55) with a 95% confidence interval of 85-99%. In the thigh, the sensitivity (16/16) and specificity (43/43) were both 100% with 95% confidence intervals of 83-100% and 93-100%, respectively. In the calf, the sensitivity was 87% (13/15) with a 95% confidence interval of 60-98% and the specificity was 97% (36/37) with a 95% confidence interval of 86-100%. We found no statistically significant difference between MR imaging and contrast venography in the detection of deep venous thrombosis. This result suggests that MR imaging is at least as sensitive and specific as contrast venography in the detection of deep venous thrombosis.

Objective To determine the incidence of deep venous thrombosis after total joint arthro-plasty. Methods Fifty-one patients had bilateral ascending venography between 3rd and 13th day after totaljoint replacement. Results The total incidence of deep venous thrombosis was 47. 1% among 51 patients whohad adequate venography, 40. 0% occurred in total hip replacement and 53. 8% in total knee replacement. Nosymptomatic pulmonary embolism was found. Conclusion The results indicate deep venous thrombosis altertotal joint arthroplasty is similar to that reported in the foreign literature. This suggests that prophylactic treat-ment is reasonable in patients with high risk of deep veinous thrombosis.[

Objective To determine the maximum venous outflow of the lower extremity deep veins in case of deep venous thrombosis (DVT). Method We use IMEX9000 multi-function vascular diagnosis instrument to examine 166 lower extremities of 100 controls the maximum venous outflow. The measurement was carried on in 46 diagnosed DVT cases for healthy and diseased limbs. Ascending venography was also performed. Three indicators were adopted including venous capacitance (VC) ,2 second venous outflow(VO) and maximum venous outflow ratio(MVOR, namely VO/VC).Result Normal MVOR is 1. 08±0. 18, irrespective of age and gender. MVOR drops significantly in diseased limb (0. 69± 0. 14),paralleling with the result of ascending venography. Conclusion MVOR has the explicit diagnosis value for lower extremity deep venous thrombosis. A MVOR 0. 9 or a MVOR ratio≥0. 2 when compared with contralateral healthy limbs is definitely diagnostic of DVT.

To determine the frequency and location of deep venous thrombosis at computed tomographic (CT) venography after CT pulmonary angiography in a large series of patients clinically suspected of having pulmonary embolism and to compare the accuracy of CT venography with lower-extremity venous sonography.Venous phase images were acquired from the diaphragm to the upper calves after completion of CT pulmonary angiography in 650 patients (373 women, 277 men; age range, 18-99 years; mean age, 63 years) to determine the presence and location of deep venous thrombosis. Results of CT venography were compared with those of bilateral lower-extremity venous sonography in 308 patients.A total of 116 patients had pulmonary embolism and/or deep venous thrombosis, including 27 patients with pulmonary embolism alone, 31 patients with deep venous thrombosis alone, and 58 patients with both. Among 89 patients with deep venous thrombosis, thrombosis was bilateral in 26, involved the abdominal or pelvic veins in 11, and was isolated to the abdominal or pelvic veins in four. In patients in whom sonographic correlation was available, CT venography had a sensitivity of 97% and a specificity of 100% for femoropopliteal deep venous thrombosis.Combined CT venography and pulmonary angiography can accurately depict the femoropopliteal deep veins, permitting concurrent testing for venous thrombosis and pulmonary embolism. CT venography also defines pelvic or abdominal thrombus, which was seen in 17% of patients with deep venous thrombosis.

A consecutive series of 118 patients was studied postoperatively by Doppler ultrasonic techniques and by either venography or radioiodinated fibrinogen. When using the latter diagnostic measures, 22 patients were shown to have deep venous thrombosis, an incidence of 18.6 per cent. The Doppler ultrasonic technique showed that 21 patients had deep venous thrombosis, an incidence of 17.7 per cent. When the patients diagnosed as having deep venous thrombosis by two separate methods were compared, it was shown that the Doppler technique gave two false-positive results and three false-negative results. It is concluded that this technique is accurate, and because of its convenience, lack of complications and ability to be repeated frequently, it should be the preferred screening technique for the diagnosis of postoperative deep venous thrombosis.

Venous thrombosis (VT) is a common disease, with an annual incidence in the general population of approximately 1 per 1,000. Factor V Leiden mutation (G1691A) (FVL) is the most common risk factor in venous thrombosis. The prevalence of FVL for thrombosis varies greatly in different regions of the world. FVL mutation has been identified both by conventional method and fluorescence resonance energy transfer (FRET) with the LightCycler. Sixty-one patients with VT, different in age and sex, were consecutively entered into this study to assess the prevalence of FVL in VT in southeast Turkey. FVL mutation was found in 24.6% (15/61). Fourteen individuals were heterozygous and 1 homozygous, a rate of 22.9% and 1.6%, respectively. In conclusion, the authors suggest that FVL mutation is common in patients with venous thrombosis in southeast Turkey.
