Summary
Endoscopic dacryocystorhinotomy (EDCR) is safe for patients on warfarin. This study shows EDCR effectively treats nasolacrimal obstruction without needing to stop anticoagulant therapy.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
Background:
- Distal nasolacrimal obstruction can cause significant epiphora.
- Anticoagulation therapy, such as warfarin, often necessitates careful management during surgical procedures.
Purpose of the Study:
- To evaluate the safety and efficacy of endoscopic dacryocystorhinotomy (EDCR) in patients who continue their anticoagulant regimen.
- To assess outcomes of EDCR in anticoagulated patients without perioperative warfarin interruption.
Main Methods:
- Retrospective case note review of 9 patients on warfarin undergoing EDCR.
- Analysis of patient demographics, surgical indications, complications, and outcomes.
- Comparison of results with non-warfarinized patients.
Main Results:
- 7 out of 9 patients achieved complete relief of epiphora.
- Two patients experienced persistent watering; one with complex canalicular blockage, another with adhesions.
- 6 patients had no complications; 2 had minor bruising, and 1 had minimal bleeding requiring brief hospitalization. No readmissions occurred.
Conclusions:
- EDCR is a safe and effective treatment for distal nasolacrimal obstruction in patients on warfarin.
- Perioperative interruption of warfarin is not necessary for successful EDCR.

01:18Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants
Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
