Livedoid Vasculopathy: diagnosis and treatment in pregnant women

Livedoid Vasculopathy is a disease characterized by occlusion of the capillaries of the dermis, without inflammatory signs. It begins with purpuric papules or macules that develop into painful ulcers, mainly involving the ankles and feet. In this case report, we describe diagnosis and treatment in a young pregnant patient, with excellent clinical response.

The prevalence of abnormal pulse wave velocity, pulse contour analysis and ankle-brachial index in patients with livedo reticularis: a controlled study

OBJECTIVE

To evaluate the prevalence of abnormal pulse wave velocity (PWV), pulse contour analysis (PCA) and abnormal ankle-brachial pressure index (ABPI) in patients with livedo reticularis (livedo) and without livedo.

METHODS

We recruited 74 patients, of whom 41 had livedo: 16 APS, 9 APS with SLE and 16 with livedo (negative for aPL or lupus). The other group of 33 patients without livedo consisted of 10 APS, 8 APS with SLE and 15 with SLE only. Livedo was diagnosed and confirmed by a dermatologist. PWV was assessed in fasting patients by the Micro Medical PulseTrace analyser using a 4 MHz continuous-wave directional Doppler probe and digital PCA was analysed by Micro Medical PulseTrace by the same operator. Chi-square with Yates's correction was used for comparing results.

RESULTS

The median age of the livedo patients was 46 (29-71) years and of the non-livedo patients was 45 (25-68) years. Abnormal values of PWV in 10/41 (24.40%), ABPI in 4/41 (9.8%) and PCA in 10/41 (24.40%) patients were observed in the livedo group and in the non-livedo group abnormal values of PWV in 1/33 (P ≤ 0.025), ABPI in 0/33 (P = NS) and PCA in 5/33 (P = NS) were observed.

CONCLUSION

Patients with livedo reticularis are more likely to have abnormal PWV, indicating arterial stiffness.

Livedoid vasculopathy: an intringuing cutaneous disease

Livedoid vasculopathy is a skin disease that occludes the blood vessels of the dermis. It has a pauciinflammatory or non-inflammatory nature. It is characterized by the presence of macular or papular, erythematous-purpuric lesions affecting the legs, especially the ankles and feet, and producing intensely painful ulcerations, which cause white atrophic scars called "atrophie blanche". This review includes studies and case reports found in the medical literature regarding the etiopathogenic associations of the disease, particularly those related to thrombophilia, their histopathological findings and the therapeutic approaches used in the difficult clinical management of these cases.

Manifestações cutâneas das trombofilias

O escopo deste artigo é revisar os estados de hipercoagulabilidade sangüínea (trombofilias) mais provavelmente encontrados por dermatologista. Seus sinais cutâneos incluem o livedo reticular, necrose cutânea, ulcerações e isquemia digital, púrpura retiforme, além de úlceras nas pernas. Revisamos seu tratamento adequado, bem como ressaltamos as manifestações cutâneas que impõem pesquisa laboratorial de trombofilias e os exames indicados nessas situações.

Vasculopatia livedóide: relato de caso com possível evidência de etiopatogenia neurovascular

A etiopatogênese da vasculopatia livedóide ainda hoje permanece indeterminada e, apesar de algumas etiologias aventadas, com freqüência elas não apresentam associação com a vasculopatia em seu curso. Os tratamentos descritos na literatura não apresentam resultados reproduzíveis. Relata-se caso de paciente de 42 anos, com vasculopatia livedóide e boa resposta ao tratamento pioneiro com a carbamazepina. A droga foi instituída diante das discretas evidências de inflamação, da inconstância dos achados relacionados às teorias sugeridas, da forte sintomatologia dolorosa e dos recentes relatos da participação neural na coagulação, que levaram os autores a considerar a possibilidade de associação vasculoneural na patogênese dessa vasculopatia.
