Endovascular management of massive post-partum haemorrhage in abnormal placental implantation deliveries.

OBJECTIVES: To retrospectively evaluate safety and efficacy of pelvic artery embolisation (PAE) in post-partum haemorrhage (PPH) in abnormal placental implantation (API) deliveries. METHODS: From January 2009 to November 2013, 12 patients with API and intractable intraoperative PPH underwent PAE after caesarean delivery to control a haemorrhage (in four of these cases after hysterectomy). Arterial access was obtained prior to the delivery; PAE was performed in the obstetrics operating room by an interventional radiologist that was present with an interventional radiology (IR) team during the delivery. RESULTS: PAE was successful in preventing bleeding and avoid hysterectomy in four cases (group A). Uterine atony and disseminated intravascular coagulation caused failure of PAE requiring hysterectomy in four patients (group B). PAE prevented bleeding post-hysterectomy in the remaining four cases (group C). Technical success (cessation of contrast extravasation on angiography or occlusion of the selected artery) was 100 %. Maternal and foetal mortality and morbidity were 0 %. CONCLUSIONS: PAE is a minimal invasive technique that may help to prevent hysterectomy and control PPH in API pregnancies without complications. Embolisation should be performed on an emergency basis. For such cases, an IR team on standby in the obstetrics theatre may be useful to prevent hysterectomy, blood loss and limit morbidity. KEY POINTS: • Endovascular treatment is a validated technique in post-partum haemorrhage. • Abnormal placental implantation is a risk factor for post-partum haemorrhage. • We propose an interventional radiologist standby in the delivery room.

Oral iron-based interventions for prevention of critical outcomes in pregnancy and postnatal care: An overview and update of systematic reviews.

OBJECTIVE: The aim of this work was to summarize and update the evidence concerning oral iron-based interventions compared to placebo or no iron-based interventions to prevent critical outcomes in pregnancy or treat critical outcomes in the postpartum phase. METHOD: Published systematic reviews (Feb 2018) and primary studies (from 2015 to March 2018) retrieved from MEDLINE, EMBASE, and the Cochrane Library were examined. The AMSTAR (Assessing the Methodological Quality of Systematic Reviews) tool was used to assess the quality of reviews. GRADE was used to rate the quality of the evidence for critical outcomes. RESULTS: Antenatal care: Compared to placebo/no treatment, iron-based therapies reduced maternal anemia at term by 59% (seven trials at low risk of bias, RR 0.41, 95% CI 0.23-0.73; I2  = 86%; moderate-quality evidence) and maternal iron deficiency anemia by 67% (RR 0.33, 95% CI 0.16-0.69; I2  = 49%). There was no evidence of difference between iron-based therapies vs control in terms of side effects (RR 1.42, 95% CI 0.91-2.21), preterm delivery (13 studies: RR 0.93, 95% CI 0.84-1.03; low-quality evidence), low birthweight (RR 0.94, 95% CI 0.79-1.13; low-quality evidence) and infant mortality (RR 0.93, 0.72-1.20; low-quality evidence). POSTNATAL CARE: There was insufficient evidence to determine whether iron-based therapies can reduce postpartum anemia. CONCLUSION: Iron supplementation is effective in preventing maternal anemia at term but not low birthweight, preterm delivery or infant mortality.

[Epidemiology of postpartum hemorrhages in the Umbrian population in the years 2006-2017.] / Epidemiologia delle emorragie post partum nella popolazione umbra nel periodo 2006-2017.

INTRODUCTION: Postpartum haemorrhage (PPH) is one of the main causes of mortality and severe maternal morbidity and its incidence is increasing also in Western countries. Aim of this study is to estimate the incidence and the trend of PPH in the Umbrian population using the validated Umbrian health database and to identify possible determinants for the development of PPH. METHODS: The source of the data was the regional Healthcare Database of the Umbria Region. The population of interest was represented by women who gave birth in Umbria between 2006 and 2017. The PPH was identified from the hospital data using the ICD-9-CM 666.x codes. Demographic data, principal and secondary diagnoses and data on maternal morbidity and blood component transfusion were collected. The incidence of PPH was calculated taking into account cases of PPH over the total number of births. The determinants of PPH, the associated morbidity and the variation in the severity of the PPH over time have been identified by logistic regression models. RESULTS: In Umbria, between 2006 and 2017, 93,403 births were registered (69% by vaginal delivery and 31% by caesarean section) and the rate of caesarean sections decreased by about 4%. The incidence of PPH increased three-fold during this period with an increase (p<0.001) of women with PPH who received transfusions. Regarding the caesarean sections, the PPH trend increased by 53% (p=0.3), while in the vaginal deliveries the PPHs increased by 233% (p<0.001). Logistic regression analysis showed that possible risk factors for the occurrence of PPH are maternal morbidity (OR 22.8, 95% CI 18.5-30.0), twin birth (OR 2.0, 95% CI 1.3-3.2) and antepartum haemorrhage (OR 5.7, 95% CI 3.1-10.4). CONCLUSIONS: The incidence of PPH has increased in recent years, while the morbidity associated with PPH has remained substantially unchanged. The study identified several risk factors responsible for PPH that can be used in the monitoring of pregnant women and for planning prevention strategies such as Patient Blood Management.

[Postpartum haemorrhage in Umbria: accuracy of the regional health information system for the code ICD-9-CM 666.x.] / Emorragia post partum in Umbria: accuratezza del sistema informativo sanitario regionale per il codice ICD-9-CM 666.x.

INTRODUCTION: Postpartum haemorrhage (PPH) is the main cause of morbidity and mortality for pregnant women. Administrative databases are useful sources of information for the assessment of PPH and related outcomes, once the corresponding ICD-9-CM code is validated. The objective of the present study is to evaluate the accuracy of the ICD-9-CM code related to PPH. MATERIAL AND METHODS: Source of the data was the Regional Healthcare Database of the Umbria Region. The population of interest were women with at least 20 weeks of gestation that delivered in any hospital in the Umbria Region during 2012-2016. Cases of interest were identified using the ICD-9-CM 666.x code. For validation purposes, both cases (women who delivered and developed PPH) and non-cases (women who delivered without occurrence of PPH) were considered and algorithms proposed. The basic criterion used for the validity of ICD-9-CM codes was the presence of bleeding ≥500 ml. Additional criteria based on values of haemoglobin or transfusion of red blood cells were considered. Sensitivity, specificity and predictive values were calculated. RESULTS: Medical charts of 422 cases and 200 non-cases were examined. Accuracy results for code 666.x related to the presence of bleeding ≥500 ml were: sensitivity 97% (95% CI, 96-99%), specificity 70% (65-76%), positive predictive value (PPV) 79% (76-82%) and negative predictive value (NPV) 95% (91-97%). The best algorithm was the one that, in addition to the basic criterion, considered both the haemoglobin values and red blood cell transfusion: sensitivity 93% (90-95%), specificity 85% (80-90%), PPV 92% (89-94%) and NPV 86% (81-90%). ICD-9 subcodes showed a higher specificity and PPV for immediate bleeding (666.0, 666.1) than delayed or secondary haemorrhage (666.2). CONCLUSIONS: The accuracy data from the present study confirm that the Regional Healthcare Database of the Umbria Region can be used as a reliable source for the evaluation of epidemiological studies relating to PPHs, in order to improve the quality of maternity care.

Diagnostic, preventive and therapeutic evidence in obstetrics for the implementation of patient blood management: a systematic review protocol.

INTRODUCTION: Patientblood management (PBM) is defined as the application of evidence-based diagnostic, preventive and therapeutic approaches designed to maintain haemoglobin concentration, optimise haemostasis and minimise blood loss in an effort to improve patient outcome. We propose a protocol for the assessment of the evidence of diagnostic, preventive and therapeutic approaches for the management of relevant outcomes in obstetrics with the aim to create a framework for PBM implementation. METHODS AND ANALYSIS: Diagnostic, preventive and therapeutic tools will be considered in the gynaecological conditions and obstetrics setting (antenatal care, peripartum care and maternity care). For each condition, (1) clinical questions based on prioritised outcomes will be developed; (2) evidence will be retrieved systematically from electronic medical literature (MEDLINE, EMBASE, the Cochrane Library, Web of Science, and CINAHL); (3) quality of the reviews will be assessed using the AMSTAR (A Measurement Tool to Assess Systematic Reviews) checklist; quality of primary intervention studies will be assessed using the risk of bias tool (Cochrane method); quality of diagnostic primary studies will be assessed using QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies); (4) the Grading of Recommendations Assessment, Development and Evaluation method will be applied to rate the quality of the evidence and to develop recommendations. ETHICS AND DISSEMINATION: For each diagnostic, preventive or therapeutic intervention evaluated, a manuscript comprising the evidence retrieved and the recommendation produced will be provided and published in peer-reviewed journals. Ethical approval is not required.

Placenta Previa Percreta: A Case Report of Successful Management via Conservative Surgery.

Placenta percreta is one of the most serious complications of placenta previa and is frequently associated with severe obstetric hemorrhage usually necessitating hysterectomy. We present a case of placenta previa percreta diagnosed by ultrasound and magnetic resonance imaging techniques, in which we accomplished conservative management of postpartum hemorrhage. The management we propose includes the following steps: preventive catheterization of the descending aorta via transhumeral access; Stark cesarean delivery; uterotonics drugs; Affronti endouterine square hemostatic sutures; intrauterine application of Bakri balloon and partial filling with 100 mL of normal saline; B Lynch suture, hysterorrhaphy, and filling a Bakri balloon with up to 500 mL of normal saline; reversible radiological embolization; and/or surgical ligation of the uterine arteries. The bleeding stopped following placement of Affronti sutures combined with external (B-Lynch suture) and internal (Bakri balloon) uterine compression. Our experience indicates that this conservative method can be considered an option in the management of selected cases of pregnancy at high risk for intrapartum hemorrhage.

B-Lynch suture, intrauterine balloon, and endouterine hemostatic suture for the management of postpartum hemorrhage due to placenta previa accreta.

OBJECTIVE: To report our experience with a new conservative management approach to treat postpartum hemorrhage (PPH) due to placenta previa accreta. METHODS: A retrospective study of 9 patients with placenta previa accreta who underwent a conservative management protocol. The protocol consists of preventive radiological catheterization of the descending aorta, cesarean delivery, use of Affronti endouterine square hemostatic sutures, and placement of an intrauterine Bakri balloon in conjunction with B-Lynch suture. In the event of failure of the protocol, subsequent management employs ligation and/or reversible embolization of the uterine arteries followed by hysterectomy if unsuccessful. RESULTS: Conservative management of PPH was successful in all 9 patients evaluated and avoided the need for ligation and/or reversible embolization of the uterine arteries. CONCLUSION: Management of PPH is dictated by several considerations including hemodynamic status and desire to preserve fertility. The initial results of this conservative protocol for treatment of PPH in high-risk patients with placenta previa accreta are encouraging.

Ovarian torsion in in vitro fertilization-induced twin pregnancy: combination of Doppler ultrasound and laparoscopy in diagnosis and treatment can quickly solve the case.

OBJECTIVE: To diagnose and treat adnexal torsion in pregnancy. DESIGN: Case report. SETTING: Obstetrics and Gynecology Department of Perugia Hospital. PATIENT(S): A 38-year-old woman, gravida 2, para 1 with bichorial twin pregnancy in the 10th week of gestation who was admitted for abdominal pain. She conceived after an IVF attempt. Even if symptoms compared 2 days before the admission, they aggravated just 2 hours before. INTERVENTION(S): An ovarian torsion was suspected, and Doppler ultrasound showed a complete absence of vascular flow. The dimension of the right ovary and the absence of ovarian blood flow were strong arguments in favor of the diagnosis of adnexal torsion, and laparoscopic ovarian adnexectomy was performed. MAIN OUTCOME MEASURE(S): The ovarian torsion was confirmed, and right adnexectomy was necessary. RESULT(S): The patient had a quick convalescence and was discharged on the third postoperative day. She had no more pain. She underwent a cesarean section for placenta previa. She and her children have remained well. CONCLUSION(S): Considering the increased number of IVF pregnancies, an ovarian torsion should be less uncommon than in the past. Doppler ultrasound should be considered as a first-line exam. The complete absence of vascular flow in the ovary may be an indication for adnexectomy. An ovarian torsion in pregnancy should be treated laparoscopically.
