Thrombosis of previously silent Persistent Sciatic Vein in non Klippel-Trenaunay syndrome patient.

Persistent Sciatic Vein (PSV) remains a rare condition with no associated malformative syndrome or concomitant Persistent Sciatic Artery (PSA). Very few case reports have been published. We report the case of a 73-year-old man who presented to the emergency room with tenderness, edema and pain of the left calf, for up to 3 days. Biology reported an elevated d-dimer level. Doppler ultrasound diagnosed proximal left deep popliteal vein thrombosis, extended to a large vein along the sciatic nerve in the posterior compartment of the thigh, and a patent superficial femoral vein. Anticoagulation therapy was initiated immediately for at least 3 months. PSV remains an understudied condition. While its prevalence is low in the general population, this anatomical condition is associated with some specific clinical situations, such as Klippel-Trenaunay syndrome (KTS) or early varicose recurrence, especially in the posterior thigh area. To our knowledge, this is the first case report of a thrombosed PSV in a patient without a KTS.

[Breast lesions as the presenting feature of giant cell arteritis]. / Pseudo-tumeurs mammaires révélant une maladie de Horton.

INTRODUCTION: Giant cell arteritis most commonly involves the external carotid branches. Although they are less typical, extra-cephalic forms have also been reported. CASE REPORT: We report the case of a 59-year-old female patient who developed bilateral, painful breast nodules with fever and altered general status since two months. Two weeks later, she presented frontal headache and scalp tenderness. A colour duplex ultrasound of the temporal artery showed a halo sign. The results of a breast needle biopsy were inconclusive but the temporal artery biopsy confirmed the diagnosis of giant cell arteritis. The disease course was rapidly favourable after institution of corticosteroids. INTRODUCTION: Breast involvement is rare but could be the first sign of giant cell arteritis. The internal mammary artery, which is a branch of the subclavian artery, can be affected and responsible for breast nodules.

[Adherence to guidelines for the treatment of venous thromboembolism in cancer patients: a retrospective analysis of 145 cases]. / Application des recommandations dans le traitement de la maladie thromboembolique veineuse chez les patients atteints de cancer: étude rétrospective sur 145 cas.

OBJECTIVES: To assess adherence to French guidelines for curative treatment of thromboembolism in cancer patients, and to identify factors limiting their implementation. PATIENTS AND METHODS: Retrospective analysis of the medical files of cancer patients diagnosed with deep vein thrombosis (DVT) and/or pulmonary embolism (PE) in one site between January 1st, 2010 and June 30th, 2011. Central venous catheter thrombosis and superficial vein thrombosis were excluded. RESULTS: The series included 145 patients, among whom 113 (78%) had solid tumors (at a metastatic stage in 68% of cases) and 33 (22%) had hematologic malignancies. Low molecular weight heparin (LMWH) was prescribed as long-term treatment (>10 days) for 83 patients (57.2%) and a vitamin K antagonist (VKA) for 33 patients (22.7%). Bleeding required treatment modifications or discontinuation in 11 (7.5%) and 10 (6.8%) patients respectively. After 6 months, LMWH, VKA and fondaparinux were prescribed for 28, 27 and six (19.3%, 18.6% et 4.1%) patients respectively. Mean duration of anticoagulation was 176.8 days. Treatment was not affected by a history of venous thromboembolism, the presence of pulmonary embolism or proximal deep vein thrombosis but it was significantly shorter in case of thrombosis limited to muscular veins (115.5 vs 182.3 days, P<0.05). Overall, guidelines were fully implemented in only 68 (46.9%) patients, with regards to the choice of pharmacological class and duration of treatment. CONCLUSION: Adherence to national guidelines is insufficient and actions must be taken to improve the management of venous thromboembolism in cancer patients.
