Objective We aimed to describe the epidemiological and clinical aspects of
deep vein thrombosis (DVT) in Behcet's disease (BD) and to determine the pa
tients at high risk for this complication.
Methods Among 113 patients with BD according to the international criteria
for classification of BD, those with DVT were retrospectively studied. The
diagnosis of DVT was made in all cases using conventional venous angiograph
y, venous ultrasonography, and/or thoracic or abdominal computed tomography
. Patients were divided in two subgroups according to the occurrence of DVT
other than cerebral thromboses. The medical records of these patients were
reviewed in order to investigate their past medical history and evaluate t
heir response to the treatment prescribed. Clinical and genetic factors (HL
A B51 and MICA 6) that might contribute to DVT were analysed by, comparing
patients with and without DVT
Results of our series were compared to those of other series in the literat
ure. Statistical analysis was by Chi square with necessary v correction and
Fischer tests. Results Forty-four patients (38.9%) had deep vein thrombosi
s of various systems with 81 localisations. There were 40 men and four wome
n (mean age 28.1 years; range 17-60). DVT appeared after the onset of disea
se with a mean delay of 3.8 years. In 6 cases, DVT revealed BD. When ive ev
aluated the risk of DVT coexistence with other clinical findings and geneti
c factors (HLA B51 and MICA 6), we,found a significant positive correlation
with sex, and positive pathergy, test.
Conclusion In our series, occurrence of DVT was significantly, associated w
ith male gender and positive pathergy, test.
