Preoperative Lower Extremity Motor Weakness Affects Deep Vein Thrombosis During the Perioperative Period of Lumbar Surgery

Study Design. Prospective cohort study. Objective. The aim of this study was to assess preoperative factors in the development/exacerbation of deep vein thrombosis (DVT) in lumbar surgery and selectively perform lower-extremity venous ultrasonography (US) in patients at risk of perioperative deep vein thrombosis (DVT). Summary of Background Data. DVT is often present before lumbar surgery and also can develop or is exacerbated postoperatively. An elevated d-dimer level is predictive of DVT but not in all patients or during every operative period. The level of the thrombogenic marker soluble fibrin monomer complex (SFMC) peaks early postoperatively. Methods. The study enrolled 698 patients (396 males; 12– 91 years [346 patients aged ≥70 years] at surgery) undergoing surgery for lumbar degenerative diseases. Patients with d-dimer levels ≥0.5 μg/mL or with a lower-extremity manual muscle test (MMT)
