ABSTRACT
Background:
Meningioma resection is associated with the risk of venous thromboembolism (VTE).Objectives:
To determine the incidence and risk factors for VTE following meningioma resection and VTE outcomes based on the type and timing of anticoagulation.Methods:
From 2011 to 2019, 901 consecutive patients underwent meningioma resection. We retrospectively evaluated the postoperative incidence of VTE and bleeding. For VTE, we determined the treatment strategy and rate of VTE complications and bleeding.Results:
Pharmacologic prophylaxis was administered to 665 (73.8%) patients. The cumulative incidence for total postoperative VTE was 8.7% (95% CI 6.9%-10.6%), and for symptomatic VTE was 6.0% (95% CI 4.6%-7.7%). A multivariable model identified the following independent predictors of symptomatic VTE history of VTE, obesity, and lack of pharmacologic prophylaxis. Following postoperative VTE, 58 (74.3%) patients received therapeutic anticoagulation either initially (33.3%) or after a median delay of 23.5 days (41.0%). Symptomatic recurrent VTE occurred in 13 (16.6%) patients. Following VTE, the use of subtherapeutic anticoagulation was associated with a lower rate of total VTE extension than no anticoagulation (17.5% vs 42.9%, OR 0.28, 95% CI 0.09-0.93). In total, 14 patients (1.6%) experienced clinically relevant bleeding 4 received therapeutic anticoagulants, 8 received prophylactic anticoagulation, and 2 received no anticoagulation. Among patients with VTE, 4 (5.1%) experienced bleeding.Conclusion:
Recognition of risk factors for VTE following meningioma resection may help improve approaches to thromboprophylaxis. The management of postoperative VTE is highly variable, but most VTE patients are ultimately treated with therapeutic anticoagulants.
