Platelet storage pool disorder: multidisciplinary planning in pregnancy.

A 32-year old primigravida woman presented for antenatal care giving a history that her mother had platelet storage pool disorder (PSPD). The patient was subsequently diagnosed with PSPD during her pregnancy and had a caesarean delivery for breech presentation at 39 weeks. In this paper, we discuss the basic science, inheritance pattern, symptoms and management of this condition, alongside the antenatal and intrapartum and postnatal management specific to it, highlighting the need for a multidisciplinary approach to care. PSPD refers to a group of rare conditions involving defects in platelet granule storage or secretion, which leads to abnormal aggregation and activation of platelets. There are both genetic and acquired forms of the condition. It is a functional platelet disorder, meaning platelet counts will usually remain in the normal range. The diagnosis may be suspected due to characteristic signs and symptoms, but patients may also be asymptomatic. There have been only a few documented cases of pregnant women with PSPD; therefore, management is not clear. Vaginal delivery is not contraindicated, however, postpartum haemorrhage should be anticipated and planned for the use of deamino D-arginine vasopressin (DDAVP), tranexamic acid, prophylactic oxytocics and prompt access to blood products, including platelets, if required. This case highlights the need for effective multidisciplinary teamwork between obstetricians, anaesthetists and haematologists to ensure high-quality care and enable careful intrapartum management planning.
