JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 1384 OP 1385 DO 10.1136/adc.67.11.1384 VO 67 IS 11 A1 R Caporali A1 A Ravelli A1 B Ramenghi A1 C Montecucco A1 A Martini YR 1992 UL http://adc.bmj.com/content/67/11/1384.abstract AB A child with systemic onset juvenile chronic arthritis (JCA) who developed a bilateral femuropopliteal vein thrombosis after plaster immobilisation following a tibial fracture is described. When the thrombosis was diagnosed, antiphospholipid antibodies detected either as lupus anticoagulant and anticardiolipin antibodies were found. This suggests that short term prophylatic antithrombotic treatment should be considered in antiphospholipid antibody positive JCA patients who require immobilisation after fractures of demineralised bones.
