•Post-operative venous thromboembolism (VTE) affects over 900,000 people annually

•The risk of VTE reaches up to 11% in patients undergoing plastic surgery procedures without chemoprophylaxis

•The Caprini Risk Assessment Model (RAM) is the most commonly used tool to evaluate risk of VTE in surgical patients

•The applicability of the Caprini RAM in patients undergoing breast reconstruction is not yet known

The purpose of this study is to utilize the National Surgical Quality Improvement Program (NSQIP) database to understand the true risk of VTE in the alloplastic and autologous breast reconstruction population, and to validate the Caprini RAM in this population to help guide chemoprophylaxis guidelines.

•Retrospective cohort study utilizing NSQIP database between 2011-2021

•Variables:

•Reconstruction modality

•Calculation of Caprini score based on known comorbidities

•Outcome: incidence of VTE

•

•Autologous reconstruction is associated with higher risk of VTE

•Multiple risk factors exist for VTE in the breast cancer population, particularly autologous reconstruction, which need to be more clearly elucidated

•Patients undergoing all breast reconstruction types should receive inpatient chemoprophylaxis

•Outpatient chemoprophylaxis varies, and should be considered on a case-by-case patients for patients with a Caprini risk score of 5 or greater
