Key result
Postoperative deep vein thrombosis occurred in 7.5% (9/120) of patients undergoing major orthopedic surgery without pharmacologic thromboprophylaxis.
Why the study?
Postoperative venous thromboembolism is an important complication in Taiwan, prompting investigation of DVT occurrence after major orthopedic surgery without pharmacologic thromboprophylaxis.
Cross-Sectional (n=120)
No
The study demonstrates a 7.5% incidence of postoperative sonographic DVT in Taiwanese patients undergoing major orthopedic surgery without pharmacologic thromboprophylaxis, consistent with other Asian cohorts.
7.5% postoperative DVT rate without prophylaxis signals ongoing VTE risk in Taiwanese orthopedic patients; leaves open whether routine prophylaxis improves net outcomes in Asian populations.
BACKGROUND/PURPOSE: Postoperative venous thromboembolism is an important complication in Taiwan. We prospectively investigated the occurrence of deep vein thrombosis (DVT) after major orthopedic surgery without pharmacologic thromboprophylaxis in a cohort of 120 patients (46 males, 74 females, median age 71 years) at our institute. METHODS: Color duplex compression ultrasonography (CUS) was used to detect DVT before and after the operation, while contrast venography was performed postoperatively for comparison and validation. RESULTS: Total knee arthroplasty (TKA, 57 cases) and total hip arthroplasty (23 cases) were the most commonly performed operations. The rate of postoperative DVT was 7.5% (9/120), including five with proximal DVT and four with distal DVT. All were detected in the limbs on the operated side. Four of them were symptomatic DVT cases. Venography was performed in 19 patients and confirmed most findings of CUS, indicating the effectiveness of CUS for detecting DVT. The type of surgery (TKA) was significantly correlated with postoperative DVT. No clinically symptomatic pulmonary embolism or sudden death events were noted. CONCLUSION: Nine out of 120 (7.5%) orthopedic patients without pharmacologic thromboprophylaxis developed postoperative sonographic DVT in our study. The DVT rate is consistent with other reports from various Asian countries and evidence from meta-analyses.
