  1. Management Challenge of Thrombophilia in Pregnancy-Case ReportDr. Gabriel Onyeka Ekekwe, Dr. Tempest Nicola, Mrs. Sandhya RaoSt Helens & Knowsley Teaching Hospitals NHSWhiston Hospital, Warrington Road, Prescot, L35 5DR • Her long term Warfarin treatment was change to clexane (dose of clexane at1mg/kg x patient’s weight of 114kg=114mg in two divided doses) at 8 weeks gestation when USS confirmed intrauterine viable pregnancy • She opted to continue with the pregnancy as the risk of fetal anomaly was perceived to be small • She presented with massive broad ligament hematoma at 22 week gestation, hence the management challenge (see USS showing haematoma) • Clexane was discontinued following consultation with the Haematologist • A retrievable vena cava filter was inserted • She had a favourable pregnancy out come. She had an elective caesarean section and bilateral tubal ligation (previous two c-sections) at 36 weeks gestation. Baby birth weight was 3.195kg • Discussions • The use of anticoagulant in pregnancy is mandatory in patients with thrombophilia • Low molecular weight heparin like clexane is the first line anticoagulant in pregnancy (1) • Clexane pose minimal risk of bleeding complication • However, it did occur in our patient and was discontinued • A retrievable VCF was then inserted • Anatomic consideration makes infrarenal VCF technically difficult in pregnancy. However, infrarenal VCF was successfully inserted in our patient • Suprarenal VCF offers an easier alternative, however, its potential thrombogenicity with possible renal compromise demand caution with this approach(4) • Conclusions • Retrievable VCF is safe alternative to anticoagulant treatment for pregnant women with increased risk of thromboembolism that are intolerant or for some reasons unsuitable for anticoagulant treatment • It should also be considered in patient with thromboembolism despite adequate anticoagulant treatment • References • 1.

The last episode was a saddle pulmonary embolism 4 years ago (see CTPA showing saddle embolus)
