 Little is known about the incidence and characteristics of deep venous thrombosis(DVT)developing shortly after neurological surgery. Lower extremity venous ultrasound scanning was performed before and after surgery, and retrospective data of 157 surgical cases, including endovascular surgery(42.0%), craniotomy(28.7%), burr hole(24.2%), and shunt(3.2%), were evaluated.

 DVT that had not been pre-operatively observed was discovered in five cases of surgery(five patients, 3.2%)on the day following the surgery, and it was asymptomatic in all cases. One patient was diagnosed with pulmonary thromboembolism as a complication. No difference in characteristic factors was observed between the presence and absence of DVT development. In addition, DVT was detected on preoperative examinations in 10 cases of surgery(10 patients, 6.4%).

 On the basis of these results, ambulation on the first postoperative day is considered mostly safe. On the other hand, taking into account the increase in the number of patients with DVT and the possibility that a thrombus present in calf veins propagates toward the proximal side, pre-and post-operative screening tests should be performed more often.
