# Severe Hemorrhage Following Dental Implant Surgery in an Anticoagulated Elderly Patient: A Case Report

## TL;DR

An elderly patient on anticoagulant therapy experienced severe bleeding after dental surgery due to improper medication management.

## Contribution

Highlights the importance of considering patient-specific factors in anticoagulant therapy during dental procedures.

## Key findings

- Severe postoperative bleeding occurred in a patient on enoxaparin without considering weight and renal function.
- Multidisciplinary care is essential for managing anticoagulated patients undergoing invasive dental treatments.
- Anticoagulant type, dosage, and patient health significantly influence surgical bleeding risks.

## Abstract

Even though dental surgery is an effective method of oral rehabilitation, it is imperative to individualize treatment planning and, especially in patients under anticoagulant therapy, to initiate early intervention in the prevention and management of hemorrhagic complications. An 80-year-old Caucasian female patient presented to the emergency department with severe oral bleeding following maxillary dental extractions and immediate implant placement. The patient was on anticoagulation therapy due to pre-existing medical conditions and had been switched to enoxaparin. However, the patient's weight and renal glomerular filtration rate were not taken into account, thus precipitating the event. Postoperative bleeding, although uncommon, can be a serious complication of oral surgery in patients on anticoagulant therapy. The risk of such complications is influenced by several factors, particularly the type and dosage of anticoagulant used, the patient's overall health, and the extent of surgical trauma. This case highlights the critical role of a multidisciplinary approach in the management of patients on anticoagulation therapy who require invasive treatments.
