Title: [abstract] A 34 YEAR-OLD COMMERCIAL DIVER WITH VISUAL CHANGES AND HEADACHE AFTER DIVING
Author: Logue, CJ; Clark, JM
Abstract: BACKGROUND: The presence of a patent foramen ovale (PFO) has been suggested to be a risk factor for the development of decompression illness (DCI). In addition, the medical literature supports a correlation between migraine headaches and the presence of a PFO. We present a case of a commercial diver who was evaluated at our facility for medical clearance to return to diving. His was experiencing frequent episodes of visual changes and persistent headaches that only occurred after divinMATERIALS AND METHODS: Mr. SW, a 34 year-old right-handed white male who works as a commercial diver was referred to our facility by the Diver's Alert Network (DAN). He recently started working at a new job site and was concerned about episodes of visual changes and headaches that always occurred like clock work approximately 2 hours after surfacing from a work-related dive. The episodes only occurred after diving and never at any other time. Although they did not occur every day the episodes had been increasing in frequency and were occurring 2-3 times per week. His most recent episode occurred 4 days prior to his visit to our facility. He had a history of two episodes of decompression illness treated with hyperbaric oxygen therapy in 1998 and 2003. After both of these episodes he was medically cleared to return to diving. In both cases, the medical clearance did not involve screening for a PFO. Routine screening labs and radiology tests were ordered that included an MRI of the brain. The patient was referred to a neuro-ophthalmologist and to cardiology to be screened for a PFRESULTS: MRI of the brain was normal. Bubble echocardiography revealed a PFO with marked right-to-left shunting during Valsalva maneuver. He had his PFO surgically closed and after the usual recuperative period returned to commercial diving. He has had no recurrence of symptomCONCLUSIONS: The patient's final diagnosis was decompression induced migraine headaches associated with a patent foramen ovale. His symptoms have completely resolved since his percutaneous closure of the PFO. This presentation will include a review of the literature with respect to relationships between the presence of a PFO and decompression illness as well as the presence of a PFO and migraine headaches.
