Removal of a Contraceptive Implant From the Brachial Neurovascular Sheath

Subdermal implantable devices are commonly used for long-acting contraception in the United States and Europe. Although relatively safe in nature, their implantation and removal may be associated with potential complications, some of which may require surgical intervention. Complications may include infection, incorrect implantation, migration, or difficulty with removal. Proximal migration has been reported; however, there are no reports of devices that have migrated within the brachial neurovascular sheath. This case report describes migration of an implantable contraceptive within the brachial neurovascular sheath that required surgical removal.
