Deep Vein Thrombosis After Major Spinal Surgery: Incidence in a Korean Population

PURPOSE : To determine the incidence of deep vein thrombosis (DVT) after major spinal surgery in a Korean population without antithrombic prophylaxis. MATERIALS AND METHODS : Three hundred and thirteen patients who underwent major spinal surgery were evaluated prospectively. All patients were examined with duplex ultrasonography assessments of both lower extremities. No specific antithrombotic prophylaxes were used in any patient before or after surgery. RESULTS : There were 4 patients with positive findings of DVT on duplex ultrasonography and only 1 patient with clinically symptomatic DVT. The overall incidence of thrombotic complications was 1.3% and incidence of symptomatic DVT was 0.3%. CONCLUSION : Considering the low rate of DVT, routine screening and prophylaxis for DVT appears unwarranted in Koreans before or after major spinal surgery.ope
