There have been few studies about the occurrence of deep venous thrombosis
(DVT) after spinal surgery in which D-dimer assay was used for screening. The
purpose of this study was to demonstrate the prevalence of DVT and pulmonary
embolism (PE) after spinal surgery. D-dimer assay was used to screening for DVT.
88 patients who had a spinal procedure between July 2006 and June 2007 at the
authors’ institution were considered for inclusion in the study. There were 48 males
and 40 females. The average age at operation was 62.4 years (range, 17-85 years).
D-dimer levels showed 10 g/ml or higher were examined by computed tomographic
pulmonary angiography and computed tomographic venography. Nine (10.2%)
patients showed D-dimer levels of 10 g/ml or higher, of whom 5 (5.7%) had DVT.
Two (2.2%) patients of 5 had PE. However, there was only one patient with clinical
signs of DVT. Statistical significance was not found in the level of procedures
(P=0.42). However, almost patients had DVT were underwent lumbar procedures.
Statistical comparison between patients who did and did not have DVT showed there
were no significant differences in age, gender, height, body weight, body mass index,
operative time, intraoperative blood loss, duration of postoperative recumbency.
There were not a few patients of DVT after spinal surgery. However, thrombosis of
the vein in the calf is generally asymptomatic. Additionally, there were a few patients
of asymptomatic PE. D-dimer assay were useful to predict DVT.
