While the Incidence of Venous Thromboembolism After Shoulder Arthroscopy Is Low, the Risk Factors Are a Body Mass Index Greater than 30 and Hypertension

Abstract

Purpose

This study aims to determine the overall incidence of venous thromboembolism (VTE) following shoulder arthroscopy and to define potential risk factors associated with its development that may help define guidelines for the use of thromboprophylaxis .

Methods

A systematic review was performed using PubMed, Embase, Web of Science, CINAHL, and Cochrane databases per PRISMA guidelines. The search terms consisted of variations of "Venous Thromboembolism" and "Shoulder Arthroscopy." Information regarding arthroscopy indication, risk factors, outcomes, and patient demographics was recorded and analyzed, and pooled odds ratios were reported for each variable.

Results

Six hundred eighty-five articles were identified in the initial search, and 35 articles reported DVT, PE, or VTE incidence following shoulder arthroscopy. Seventeen nonoverlapping articles with a unique patient population incidence rates. Four articles were then used for subgroup meta-analysis. The incidence rate of VTE was 0.24%, ranging from 0.01% to 5.7%. BMI >30 (OR = 1.46; 95% CI = [1.22, 1.74]; I ² = 0%) and hypertension (OR = 1.64; 95% CI = [1.03, 2.6]; I ² = 75%) were significant risk factors ( P < .05) for developing VTE following shoulder arthroscopy. Diabetes (OR = 1.2; 95% CI = [0.97, 1.48]; I ² = 0%), insulin-dependent diabetes (OR = 5.58; 95% CI = [0.12, 260.19]; I ² = 85%), smoking (OR = 1.04; 95% CI = [0.79, 1.37]; I ² = 12%), male sex (OR = 0.95; 95% CI = [0.49, 1.85]; I ² = 86%) and age over 65 (OR = 4.3; 95% CI = [0.25, 72.83]; I ² = 85%) were not associated with higher VTE risk.

Conclusion

The VTE incidence following shoulder arthroscopy is low at 0.24%. Patients with BMI >30 and hypertension are at a higher risk for VTE after shoulder arthroscopy.
