PURPOSE: To evaluate the usefulness of soleal vein (SOV) diameter as a predictor of new onset of deep vein thrombosis (DVT) in acute stroke patients.
METHODS: A total of 121 acute stroke patients who were admitted within 48 h of onset underwent a calf vein ultrasonography (CVUS) examination within 7 days after hospitalization. They were evaluated for the presence of DVT and risk factors including maximum SOV diameter. Next, the patients in whom DVT was not detected at the first CVUS examination underwent a second CVUS examination on the 21st hospital day, and were evaluated for the presence of new DVT.
RESULTS: DVT was detected in 27 of 121 patients at the first CVUS examination. A significant association was noted between the presence of DVT and higher levels of soluble fibrin monomer, D-dimer, and C-reactive protein, and a higher rate of having cancer concomitantly. Furthermore, 50 of 94 patients without DVT at the first CVUS examination underwent a second CVUS examination. Of the 94 patients, 44 were excluded, because they were discharged by the 21st day. Note that DVT was newly developed in 12 of the 50 patients who underwent the second CVUS. A significant association was found between the presence of new DVT and the rate of history of stroke, hematocrit level, and maximum SOV diameter at the first examination.
CONCLUSION: In our acute stroke patients, SOV dilation, history of stroke, and elevated hematocrit level were found to be associated with risk of developing a new DVT.
