Abstract

Purpose

To survey current practice and opinion regarding the cessation of antiplatelet and anticoagulant agents prior to vitreoretinal surgery, with special emphasis on novel anticoagulants, and to provide an overview of current literature.

Methods

An online survey was sent to 167 members of the British and Eire Association of Vitreoretinal Surgeons (BEAVRS). A literature search and analysis was conducted on studies that reviewed the bleeding risk of antiplatelet and anticoagulant agents.

Results

The majority (93% for aspirin, 82% for clopidogrel) of respondents would not suspend antiplatelet administration, and 79% would not stop warfarin before vitreoretinal surgery. Regarding the novel anticoagulants (factor Xa inhibitors), 58% would not stop them, and 24% were unsure. Eighty-three percent of the surgeons were not confident regarding the management of factor Xa inhibitors preoperatively. Thirty-one percent of the respondents felt that anticoagulation cessation was independent of the type of vitreoretinal surgery, whereas 9% each felt that they would stop anticoagulation if possible for diabetic vitrectomy and retinectomy. Published evidence suggests that antiplatelet agents and warfarin do not confer a significantly greater risk of intra- or perioperative bleeding. Evidence regarding the novel anticoagulants is sparse.

Conclusions

Further evaluation of novel anticoagulants in vitreoretinal surgery is required in order to provide evidence-based recommendations and address variations in practice.
