Lemierre's Syndrome in a Commercial Airline Pilot.

A 39-year-old commercial pilot developed Lemierre's syndrome with gas-forming thrombophlebitis in multiple venous sinuses and the internal jugular vein following an acute oropharyngeal infection.

• The patient was a commercial pilot flying air cargo operations in Australia.
• CT scan showed gas-forming thrombophlebitis in the superior sagittal sinus, right transverse sinus, and right internal jugular vein.
• The patient initially presented to the emergency department with a sore throat, was given antibiotics, and discharged.
• He re-presented 2 days later with fever and increased painful swelling of the right lateral neck.

Initial infection control was challenging despite broad-spectrum antibiotics, requiring staged surgical intervention in addition to anticoagulation with enoxaparin.

• The patient was started on broad-spectrum antibiotics and anticoagulation with enoxaparin.
• Initial control of the infection was challenging despite antibiotic therapy.
• A staged surgical exploration and washout of the neck was required.
• After reintervention, the patient made an excellent recovery.

The pilot's anticoagulation therapy necessitated a wait of several months before aviation authorities permitted him to resume commercial flying.

• The pilot had to wait several months for clearances from various specialties.
• Clearance was required from the Australian and New Zealand aviation authorities before he was allowed to fly commercially again.
• The delay was attributed specifically to his anticoagulation status.

There is no universal consensus in the medical literature on the role, timing, duration, dosing, or type of anticoagulation for Lemierre's syndrome.

• The role of anticoagulation in Lemierre's syndrome remains debated and there is no universal consensus on best practice.
• The lack of consensus makes it challenging to publish unified recommendations for Aviation Medical Examiners.
• Lemierre's syndrome is described as a rare, life-threatening complication of acute oropharyngeal infection commonly associated with Fusobacterium necrophorum.
• Septic emboli in LS can metastasize to the liver, lungs, endocardium, and joints.

The case highlights the need for an individualized approach when assessing fitness to fly for pilots who have been treated with anticoagulation for Lemierre's syndrome.

• The authors emphasize the importance of an individualized approach to prevent unjustified grounding of pilots on anticoagulation.
• No unified recommendations for Aviation Medical Examiners currently exist for this condition.
• Multiple specialty clearances were required before aviation authority approval was granted.
