Application of the Caprini Risk Assessment Model to Select Patients for Extended Thromboembolism Prophylaxis After Sleeve Gastrectomy

Independent predictors and timing of portomesenteric vein thrombosis after bariatric surgery

“…Although associated risk factors such as procedure type and a history of hypercoagulability have been described, specific independent predictors for PVT are not well defined (5,6) . In addition, prior studies have demonstrated that the majority of PVTs occur within the first postoperative month, which supports the use of extended prophylaxis (7,8) . However, appropriate patient selection, effectiveness, and exact duration of any chemoprophylaxis to prevent PVT remains unclear.…”

“…This has therapeutic implications for the duration of extended chemoprophylaxis required to reduce the risk of PVT following bariatric surgery. Extended chemoprophylaxis to prevent PVT has been advocated by some, but patient selection, effectiveness, and duration of therapy has been unclear (7,8) . Based on our findings and the relevant literature we have several recommendations.…”
