Is It Really Safe to Discontinue Anticoagulant Treatment Before Ptosis Surgery From Serious Bleeding?

PURPOSE: To evaluate the effects of discontinuing anticoagulants (ACs)/antiplatelets (APs) preoperatively on surgery for blepharoptosis. METHOD: A retrospective analysis included patients with acquired blepharoptosis who underwent surgical correction, and were followed for more than 1 month. Patients were classified into 2 groups depending on AC/AP treatment or otherwise. All patients taking AC/AP discontinued with the treatment 1 week prior to surgery in accordance with our clinical guidelines. Preoperative and postoperative marginal reflex distance 1 (MRD1) and ecchymosis grade were evaluated and compared. RESULTS: Group 1 (AC/AP treatment cessation) included 47 patients with 93 eyelids, and group 2 (control) included 51 patients with 98 eyelids. The preoperative MRD1 showed no significant difference between groups. Group 1 showed a significantly higher rate of severe ecchymosis (41.8 versus 22.4%, P = 0.004) at 1 week of surgery as well as persistent ecchymosis (58.8 versus 7.3%, P = 0.000) compared with group 2 postoperatively at 1 month. Postoperative MRD1 was significantly lower in group 1 at 1 week (P = 0.019). However, the MRD1 and degree of improvement in lid height (postoperative MRD1 "preoperative MRD1) was not significantly different between the 2 groups (P = 0.499, P = 0.058) at 1 month postoperatively. CONCLUSIONS: Postoperative ecchymosis was more severe in group 1 at 1 month after ptosis surgery even though the ACs/APs were discontinued. Surgeons should be careful about this before operation. THE SYNOPSIS: Significant ecchymosis could occur even after discontinuation of antithrombotic agents in patients with a history of taking medication in ptosis surgery. Surgeons should be careful about this before operation.
