[Detection of deep vein thrombosis in preoperative patients using venous ultrasonography].

BACKGROUND

Using Doppler ultrasonography (US), deep vein thrombosis (DVT) has been detected in the lower limbs of preoperative patients.

METHODS

Of 1,087 patients scheduled for surgery from January to June 2002, US was performed in 85 patients with a history of thromboembolism, a presence of abnormality in the lower extremities, or prolonged bed rest.

RESULTS

In five patients thrombi were detected by US, but not in patients with a history of thromboembolism. To prevent pulmonary thromboembolism, prophylactic treatments were performed in 5 patients with DVT complications.

CONCLUSIONS

We conclude that US should be performed on the preoperative patients with a presence of abnormality in the lower extremities or those who have had prolonged bed rest.
