Summary
Foam sclerotherapy can cause temporary visual disturbances and speech issues, even in patients without migraine. A patent foramen ovale (PFO) was found, but the exact cause of these neurological deficits remains unclear.
Area of Science:
- Vascular Surgery
- Neurology
- Sclerotherapy
Background:
- Foam sclerotherapy is a common treatment for venous malformations.
- Neurological adverse events following sclerotherapy are rare.
Observation:
- A patient undergoing polidocanol foam sclerotherapy experienced immediate photopsiae and transient speech disturbance.
- Pathological examination revealed a patent foramen ovale (PFO).
Findings:
- The patient presented with transient visual and speech deficits post-sclerotherapy.
- A patent foramen ovale (PFO) was identified, a condition common in the general population.
Implications:
- The occurrence of neurological deficits after foam sclerotherapy, despite PFO identification, suggests potential unknown etiological factors.
- Further research is needed to elucidate the precise mechanisms and risk factors for neurological complications in foam sclerotherapy.
