          Abstract

          Klippel-Trenaunay-Weber syndrome (KTWS) is a congenital malformation syndrome involving blood and lymph vessels and disturbed bone and soft tissue growth. Complications of KTWS include deep-vein thrombosis, pulmonary embolism, gastrointestinal bleeding, and vascular (usually lymphatic) blebs within capillary malformations. We present a case of a young male patient with KTWS who presented with superficial venous thrombosis and microangiopathic hemolytic anemia in a presentation similar to disseminated intravascular coagulation. He was ultimately maintained on prophylactic rivaroxaban to prevent recurrent thrombotic events. We performed a literature search to identify similar cases and to summarize common presenting features and treatment modalities that were offered. Résumé Le syndrome de Klippel-Trenaunay-Weber (KTWS) est un syndrome de malformation congénitale impliquant le sang et les vaisseaux lymphatiques et les os perturbés et la croissance des tissus mous. Les complications de la KTWS comprennent la thrombose veineuse profonde, l'embolie pulmonaire, les saignements gastro-intestinaux et les bulles vasculaires (habituellement lymphatiques) dans les malformations capillaires. Nous présentons un cas d'un jeune patient mâle avec KTWS qui a présenté une thrombose veineuse superficielle et une anémie hémolytique microangiopathique dans une présentation semblable à la coagulation intravasculaire disséminée. Il a finalement été maintenu sur des rivaroxaban prophylactiques pour prévenir les épisodes récurrents de purpura. Nous avons effectué une recherche documentaire pour identifier des cas similaires et pour résumer les caractéristiques communes de présentation et les modalités de traitement qui ont été offerts.

          Interpretation of benefit-risk of enoxaparin as comparator in the RECORD program: rivaroxaban oral tablets (10 milligrams) for use in prophylaxis in deep vein thrombosis and pulmonary embolism in patients undergoing hip or knee replacement surgery.

          The Regulation of Coagulation in Major Orthopedic surgery reducing the Risk of DVT and PE (RECORD) clinical program of rivaroxaban consists of 4 phase III clinical trials comparing rivaroxaban with enoxaparin for the prevention of venous thromboembolism (VTE) in patients undergoing either total hip or total knee replacement surgery. Despite the comprehensive and extensive nature of this program, it had some logistic issues that included the dosing of the enoxaparin which was not only inconsistent with the recommendations but the dosages used were not optimal. The duration of treatment while consistent with rivaroxaban did vary with enoxaparin and was somewhat short. The bleeding definitions and safety evaluations were not consistent in accordance with the current recommendations. Moreover, the RECORD program has no power to show differences in major bleeding. The cardiovascular rebound phenomenon should have been adequately addressed and may require additional clinical validation to establish the safety of rivaroxaban. Although the US Food and Drug Administration (FDA) advisory committee has recommended approval of rivaroxaban, the reported analysis strongly suggests additional clinical validation on the claimed benefit/risk ratio of this monotherapeutic anticoagulant.

            Recurrent pulmonary embolism associated with Klippel-Trenaunay-Weber syndrome.

            Klippel-Trenaunay-Weber syndrome (KTWS) is a rare, congenital disorder characterized by the triad of varicose veins, cutaneous hemangiomas, and hypertrophy of soft tissue and bone. We present the case of a woman with KTWS, cor pulmonale, and death due to recurrent pulmonary embolism (PE). The risk of deep venous thrombosis and PE in patients with KTWS is evaluated, and treatment recommendations are made with emphasis on the role of early, aggressive management in the subset of patients with KTWS known to have thromboembolic disease.
