title: Remnants of a 35-year-old ventriculo-atrial shunt presenting as orofacial pain.
abstract: A 36-year-old man presented to his general dental practitioner with pain in the right jaw and neck. This was initially treated as a dento-alveolar abscess. Three days later, he presented to the oral and maxillofacial unit with neck swelling to the right side. An ultrasound confirmed the swelling was due to thrombosis associated with remnants of a ventriculo-atrial (VA) shunt in the right internal jugular vein. This had been placed during the patient's infancy and apparently removed at the age of 8 years. The patient was treated conservatively with warfarin and Coamoxyclav. The patient made a full recovery and was placed on long-term anticoagulant therapy. The introduction of cerebral spinal fluid shunt procedures for the treatment of hydrocephalus has resulted in a reduction in the mortality rate from 80% to 15-20%. Various thrombo-embolic complications have been described with VA shunts. A thorough medical history is absolutely essential in order to identify uncommon causes of common presentations.
