105 Maternity and Obstetrics NMH Annual Rep t | 2020 On Saturday the 29th of February 2020, Placenta Accreta Ireland, in partnership with The National Maternity Hospital and The NMH Foundation, held its inaugural fundraising Ladies Springtime Lunch. The event sold out; 363 ladies and three men came to mark the occasion and support this very worthy cause. The funds raised are being used to support research and initiatives to further understand the causes and consequences of a pregnancy complicated by Placenta Accreta. Placenta Accreta is a rare condition, which has increased substantially from the 1980s, from 0.8 per 1000 deliveries to 3 per 1000 deliveries in the past decade. There are reported mortality rates of up to 7%, with a hysterectomy (and therefore infertility) being a consequence in about 80% of cases. "Placenta accreta spectrum" covers a range of clinical conditions where the placenta is embedded too deeply into the lining of the womb. It therefore does not separate from the womb when a baby is delivered. There were 0-2 cases per year from 2000-2010. There have been 3-10 cases per year since 2010. It is hoped that post-COVID, The Ladies Springtime Lunch will become an annual Springtime Lunch. Placenta Accreta Spectrum (PAS) refers to a range of clinical conditions characterised by abnormal placental adherence to the uterine wall. The incidence of PAS has increased substantially from 0.8 per 1000 deliveries in the 1980s to 3 per 1000 deliveries in the past decade, largely attributed to a rising global caesarean section rate. 2 The condition is associated with significant maternal morbidity. The PAS multidisciplinary team (MDT) service was established in The National Maternity Hospital in June 2017. This service provides care to patients of NMH and also accepts external referrals nationwide. The MDT aims to allow for the optimisation of antenatal risk factors, the development of both elective and emergency delivery plans and the appropriate postnatal follow up. On average 5 cases are discussed at each MDT (range 2-10). In 2020, 15 patients with PAS were delivered, this included 11 caesarean hysterectomies and 4 uterine conservation procedures. 40% (n=6) of these patients were external referrals. See table 1 below for details. The median gestation at delivery was 34+3 wks (range 29+6 wks – 37+1 wks). 33 % of cases required emergency delivery (n=5) with 2 of these cases requiring emergency delivery in peripheral hospitals. The average estimated blood loss (EBL) is 1987mls (range 660 – 5800mls). With elective delivery the average EBL is 1650mls (range 600 - 5800mls) compared to 2660mls (range 1200 - 5000mls) in the emergency setting. Eight patients (53%) did not require a blood transfusion. All patients received social work, perinatal mental health, physiotherapy and lactation support as well as information about the Placenta Accreta Ireland Support Group. Placenta Accreta Spectrum
