What Researchers Did
Researchers hypothesized that Cutis Marmorata skin decompression sickness is caused by gas bubbles embolizing the brainstem, rather than local skin bubbles.
What They Found
They observed that Cutis Marmorata is frequently associated with a Patent Foramen Ovale (PFO), with almost 100% prevalence of PFO in these patients using specific echocardiographic techniques. Based on this, they concluded that Cutis Marmorata is a serious neurological manifestation of brainstem bubble embolization, often accompanied by other symptoms like visual distortions or vertigo.
What This Means for Canadian Patients
Canadian patients presenting with Cutis Marmorata after diving should be evaluated for potential brainstem bubble embolization, rather than considering it a mild skin condition. This reclassification could lead to more aggressive and appropriate neurological treatment, potentially improving outcomes for divers.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian researchers or participants.
Study Limitations
A key limitation is that this paper presents a hypothesis rather than empirical data from a clinical trial to directly prove the proposed mechanism.
