Recreational divers may experience Raynaud's phenomenon, a condition causing blue discoloration of digits. This case report details its initial manifestation during a warm-water scuba dive.

Area of Science:

  • Diving Medicine
  • Vascular Medicine

Background:

  • Raynaud's phenomenon is a known condition triggered by cold exposure.
  • Its occurrence in recreational divers is not well-documented in medical literature.

Observation:

  • A case of primary Raynaud's phenomenon initially manifested during a warm-water scuba dive.
  • An 18-year-old male experienced painless, blue discoloration on digits after dives to 90 feet.
  • Symptoms resolved within an hour of surfacing.

Findings:

  • Physical examination and laboratory tests were normal.
  • Arterial Doppler measurements showed diminished blood flow in digits upon temperature provocation.
  • These findings suggest Raynaud's phenomenon in the absence of typical triggers.

Implications:

  • This case highlights the potential for Raynaud's phenomenon in recreational divers.
  • Further research is needed to understand the incidence and risk factors in this population.
  • Consideration of vascular assessments may be important for divers experiencing unusual symptoms.
