HERRERA-SANCHEZ, Alejandro; MADRIAGAL-ALVARADO, María José; MONCAYO, Gabriela  and  VERDINI, Fabrizio. Medium-pressure hyperbaric oxygen therapy for livedoid vasculopathy. Medicina (B. Aires) [online]. 2022, vol.82, n.4, pp.613-616. ISSN 0025-7680.

Livedoid vasculopathy (LV) is a cutaneous manifestation of several diseases that lead to non-inflammatory thrombosis of dermal vessels. We report the case of a 26-year-old female with a 4 years and 8 months-old history of diagnosis of LV and a non-healing ulcer of more than a year of evolution. Because of refractory response to standard care, low-pressure hyperbaric oxygen (LPHBOT) was added to the therapeutic scheme (azathiopine 2.5 mg/kg, folic acid and acetylsalicylic acid). After 12 sessions of LHBOT (60 min, 1.45 ATA ≈100% O2), ulcers achieved complete healing with significant pain relief and no recurrence was present over 6 months. More studies are necessary to determine the effectiveness of HBOT for LV treatment.
