          Abstract

          OBJETIVO: Demonstrar os achados em ressonância magnética (RM) da tromboflebite plantar. MÉTODOS: Revisão retrospectiva de 20 pacientes com dor na região plantar nos quais os achados de ressonância magnética indicaram tromboflebite plantar. RESULTADOS: Foram avaliados 14 homens e seis mulheres, com idade média de 46,7 anos. Oito desses pacientes também foram submetidos à ultrassonografia com doppler, que confirmaram a tromboflebite. As imagens de ressonância magnética foram avaliadas em consenso por dois radiologistas com experiência em radiologia do sistema musculoesquelético (mais de 10 anos cada um), demonstrando edema perivascular em todos os 20 pacientes (100%) e edema muscular em 19 dos 20 pacientes (95%). Todos os 20 pacientes apresentavam intensidade de sinal intermediária intraluminal em T2 (100%) e ectasia venosa estava presente em 17 dos 20 casos (85%). Veias colaterais foram visualizadas em um dos 20 pacientes (5%). Todos os 14 casos (100%), nos quais o contraste intravenoso foi administrado, apresentavam realce dos tecidos perivenulares e defeito de enchimento intraluminal. Ectasia venosa, perda da compressibilidade e ausência de fluxo na ultrassonografia com doppler também foram observados em todos os oito casos examinados pelo método. CONCLUSÕES: A RM é um método sensível na avaliação de tromboflebite plantar em pacientes com dor plantar.

          OBJECTIVE: demonstrate the magnetic resonance imaging (MRI) findings in plantar thrombophlebitis. METHODS: Retrospective review of twenty patients with pain in the plantar region of the foot, in which the MRI findings indicated plantar thrombophlebitis. RESULTS: A total of fourteen men and six women, mean age 46.7 years were evaluated. Eight of these patients also underwent Doppler ultrasonography, which confirmed the thrombophlebitis. The magnetic resonance images were evaluated in consensus by two radiologists with experience in musculoskeletal radiology (more than 10 years each), showing perivascular edema in all twenty patients (100%) and muscle edema in nineteen of the twenty patients (95%). All twenty patients had intraluminal intermediate signal intensity on T2-weighted (100%) and venous ectasia was present in seventeen of the twenty cases (85%). Collateral veins were visualized in one of the twenty patients (5%). All fourteen cases (100%), in which intravenous contrast was administered, showed perivenular tissues enhancement and intraluminal filling defect. Venous ectasia, loss of compressibility and no flow on Doppler ultrasound were also observed in all eight cases examined by the method.

              Isolated thrombosis of plantar veins. Case report.

              A Cavezzi (1999)
              The author reports a case of isolated thrombosis of plantar veins, a rare finding in the international medical literature, in a patient who had a previous knee arthrocentesis and a strict localized bandage. The clinical aspect of perimalleolar-podalic (mainly plantar) oedema, with localized pain, was followed by colour flow duplex investigation, which is considered the fundamental and most useful means to achieve the diagnosis and to perform an adequate follow-up. Pharmacological therapy of such kinds thrombosis may be of an antithrombotic or anticoagulant nature, always associating elastic compression. Aethiopathogenesis of this localized thrombosis is still uncertain, but probably in situ mechanical compressions may play an important role.
