RESUMO
OBJECTIVES: Chorioangioma represents a challenge due to the rarity of the condition, paucity of sufficient management guidelines, and controversies regarding the best invasive fetal therapy option; most of the scientific evidence for clinical treatment has been limited to case reports. The aim of this retrospective study was to review the natural antenatal history, maternal and fetal complications, and therapeutic modalities used in pregnancies complicated with placental chorioangioma at a single Center. METHODS: This retrospective study was conducted at King Faisal Specialist Hospital and Research Center (KFSH&RC) in Riyadh, Saudi Arabia. Our study population included all pregnancies with ultrasound features of chorioangioma, or histologically confirmed chorioangiomas, between January 2010 and December 2019. Data were collected from the patients' medical records, including the ultrasound reports and histopathology results. All subjects were kept anonymous; case numbers were used as identifiers. Data collected by the investigators were entered into Excel worksheets in an encrypted format. A MEDLINE database was used to retrieve 32 articles for literature review. RESULTS: Over a 10-year period between January 2010 and December 2019, 11 cases of chorioangioma were identified. Ultrasound remains the gold standard for diagnosis and follow-up of the pregnancy. Seven of the 11 cases were detected by ultrasound, allowing proper fetal surveillance and antenatal follow-up. Of the remaining six patients, one underwent radiofrequency ablation, two underwent intrauterine transfusion for fetal anemia due to placenta chorioangioma, one had vascular embolization with an adhesive material, and two were managed conservatively until term with ultrasound surveillance. CONCLUSIONS: Ultrasound remains the gold standard modality for prenatal diagnosis and follow-up of pregnancies with suspected chorioangiomas. Tumor size and vascularity play a significant role in the development of maternal-fetal complications and the success of fetal interventions. To determine the superior modality of fetal intervention mandates more data and research; nevertheless, Fetoscopic Laser Photocoagulation and embolization with adhesive material seem to be a lead choice, with reasonable fetal survival.

OBJECTIVE: To explore clinicopathological characteristics, diagnosis, differential diagnoses, treatment, and prognoses of placental chorioangioma (PCA). METHODS: Placenta of 77 cases of PCA firmly diagnosed by pathology from 2009 through 2019 were collected, and clinicopathological characteristics of the patients were retrospectively analyzed. RESULTS: Seventy-seven patients were 20-41 (mean age, 28.8) years old at onset. Thirty patients showed pregnancy comorbidity. In one patient with the largest tumor (diameter, 16 cm), intrauterine fetal demise occurred at 33 weeks of gestation. Tumors were macroscopically manifested. The placental fetal surface showed a raised dark red to a pale pink nodule, quasi-round, with a maximum diameter of 0.2-16 cm. Microscopically, the tumors had a lot of capillaries and some interstitial loose connective tissue. One case was of atypical cellular chorioangioma. Immunophenotypically, CD34 (+) and Ki-67 proliferation indexes were less than 10%. CONCLUSIONS: Large PCA often accompanies pregnancy comorbidity. Atypical cellular chorangioma is rare and may be misdiagnosed as a malignant tumor. Therefore, improvement of understanding of such tumors can provide a basis for clinical diagnosis and intervention.

Placental chorangiomas can cause a high-output fetal state and increase neonatal morbidity and mortality. There is a paucity of data published describing the optimal treatment of these cases, and methods for occlusion to date include placement of vascular clips, bipolar cautery, injection of alcohol or surgical glue, interstitial laser, and microcoil embolization. We report 2 cases of prenatally diagnosed chorangiomas that caused a high-output fetal state and were successfully treated with microcoil embolization. This case series describes our technique and supports microcoil embolization as a potentially safe and effective antenatal treatment option in symptomatic chorangiomas.

Giant chorioangiomas are benign placental tumours, which can have potential severe fetal consequences. Complications in pregnancy include polyhydramnios, fetal hydrops and growth restriction. Such pregnancies can carry a significant risk of poor perinatal outcome and require close monitoring. Therapeutic options include fetoscopic or interstitial vessel ablation, chemosclerosis and embolisation. Where there is no evidence of fetal compromise, such pregnancies can successfully be managed conservatively.

Chorioangiomas are generally small and associated with favorable outcomes, but large tumors can cause serious fetal complications, such as polyhydramnios, fetal anemia, intrauterine growth restriction, cardiac failure, fetal hydrops, and intrauterine fetal death. Signs of fetal cardiac failure on ultrasonography are indications for urgent in utero interventions. We report a case of a giant chorioangioma causing fetal cardiac failure at 26+3 weeks' gestation, which was treated by embolization of the feeding vessels. We utilized a mixture of n-butyl cyanoacrylate (nBCA, Histoacryl®) and iodized oil (Lipiodol®) as an embolic agent. Fetal hydrops resolved in 4 weeks, and the cardiac size and function normalized 8 weeks after the embolization. A healthy male baby was born at the 37+5th gestational week by cesarean section.

Chorioangioma is a rare vascular placental tumour. Large chorioangiomas are known to have many maternal and perinatal complications. The case of placental chorioangioma detected via ultrasound is presented. This paper is focused on non-invasive fetal electrocardiography (NI-FECG) clinical use for diagnosing fetal anemia in chorioangioma.A 22-year-old primigravida was admitted to the department of fetomaternal medicine at 30 weeks of gestation. She had threatened preterm labour, polyhydramnios, and breech presentation. The large echogenic mass of 77âmm×66âmm×83âmm, located in the uterine bottom, protruded into the amniotic cavity, and connected to the marginal sinus of the placenta was determined via ultrasound. The sinusoidal pattern of beat-to-beat variations was diagnosed via NI-FECG in spite of normal blood flow velocity in the fetal middle cerebral artery. Therefore, NI-FECG was superior in the detection of fetal anemia. The female baby weighing 1500âg and measuring 42âcm in length, with a head circumference of 30âcm and Apgar score 3â¶5, was delivered by caesarean section. The baby had severe anemia and respiratory distress syndrome.NI-FECG was a good option for the clinician for the timely and accurate diagnosis of fetal anemia and fetal compromise in placental chorioangioma.

PURPOSE OF REVIEW: Cancer diagnosis in young pregnant women challenges oncological decision-making. The International Network on Cancer, Infertility and Pregnancy (INCIP) aims to build on clinical recommendations based on worldwide collaborative research. RECENT FINDINGS: A pregnancy may complicate diagnostic and therapeutic oncological options, as the unborn child must be protected from potentially hazardous exposures. Pregnant patients should as much as possible be treated as non-pregnant patients, in order to preserve maternal prognosis. Some approaches need adaptations when compared with standard treatment for fetal reasons. Depending on the gestational age, surgery, radiotherapy, and chemotherapy are possible during pregnancy. A multidisciplinary approach is the best guarantee for experience-driven decisions. A setting with a high-risk obstetrical unit is strongly advised to safeguard fetal growth and health. Research wise, the INCIP invests in clinical follow-up of children, as cardiac function, neurodevelopment, cancer occurrence, and fertility theoretically may be affected. Furthermore, parental psychological coping strategies, (epi)genetic alterations, and pathophysiological placental changes secondary to cancer (treatment) are topics of ongoing research. Further international research is needed to provide patients diagnosed with cancer during pregnancy with the best individualized management plan to optimize obstetrical and oncological care.

BACKGROUND: The effect of inflammatory bowel disease (IBD) on pregnancy-related outcomes remains unknown. AIM: To determine the risk of adverse maternal, placental and obstetric outcomes in IBD METHODS: We searched Medline, Embase and Cochrane library through May 2019 for studies reporting adverse maternal, placental and obstetric outcomes in patients with IBD. Odds ratios (OR) with 95% confidence intervals (CI) were calculated for these outcomes in patients with IBD compared to healthy controls. RESULTS: Fifty-three studies were included (7917 IBD pregnancies and 3253 healthy control pregnancies). Caesarean delivery was more common in patients with IBD compared to healthy controls (OR 1.79, 95% CI, 1.16-2.77). This remained significant for UC (OR 1.80, 95% CI, 1.21-2.90) but not CD (OR 1.48, 95% CI, 0.94-2.34). Similarly, gestational diabetes occurred more commonly in IBD (OR 2.96, 95% CI, 1.47-5.98). The incidences of placental diseases were 2.0% (95% CI, 0.9%-3.1%) for pre-eclampsia, 3.3% (95% CI, 0%-7.2%) for placental abruption, 0.5% (95% CI, 0.2%-0.9%) for placenta previa and 0.3% (95% CI, 0%-0.5%) for chorioamnionitis. Patients with IBD were more likely to experience preterm prelabour rupture of membranes (OR 12.10, 95% CI, 2.15-67.98), but not early pregnancy loss (OR 1.63, 95% CI 0.49-5.43). Anti-tumour necrosis factor therapy was not associated with chorioamnionitis (OR 1.12, 95% CI, 0.16-7.67), early pregnancy loss (OR 1.49, 95% CI, 0.83-2.64) or placenta previa (OR 1.58, 95% CI, 0.30-8.47). CONCLUSIONS: Gestational diabetes and preterm prelabour rupture of membranes occurs more commonly in patients with IBD, although the incidence of placental diseases remains low.

Objective: To measure the relative risk of pregnancy complications and adverse outcomes in women with placental chorioangioma, and postnatal developmental deficiencies in their offspring.Methods: We designed a retrospective cohort study using records from 140,387 pregnancies at our hospital between 1 January, 2008 and 1 July, 2017. Follow-up of children in the placental chorioangioma group was conducted by phone interview.Results: Placental chorioangioma was diagnosed in 56 patients (incidence = 0.04%). Fifty-one cases were detected during routine prenatal ultrasound. Placental chorioangioma patients were at increased risk for fetal loss or induced abortion (RR = 9.93, 95% CI [4.66, 21.20]), preterm birth (n = 13, RR = 2.45, 95% CI [1.52, 3.95]), birth by cesarean section (n = 45, RR = 1.62, 95% CI [1.42, 1.84]), and polyhydramnios (n = 9, RR = 9.98, 95% CI [5.48, 18.18]), but not fetal distress (n = 5, RR = 0.49, 95% CI [0.22, 1.15]) or preeclampsia (n = 5, RR = 1.61, 95% CI [0.70, 3.73]), although there was an increased risk for preeclampsia after controlling for preterm birth (n = 3, RR = 3.6, 95% CI [1.33, 9.74]). No developmental complications were reported in offspring.Conclusion: Placental chorioangioma increases the risk of fetal demise, pregnancy complications and adverse outcomes. In cases with mild complications or when early cesarean termination of pregnancy is feasible, the prognosis is excellent.

Placental chorioangioma is a limited non trophoblastic vascular tumour that may causes fetal complications as well as post-natal ones. We reported in here the first case of an in utero embolization of chorioangioma diagnosed at 22 W G with a post-natal diagnosis of neonatal multifocal hemangioma with a good outcome. The chorioangioma was embolized using GLUBRAN 2 ® (cyanolacrylate) a biologic surgical glue at 26 W G. Premature rupture of membrane occurred at 28 W G. A cesarean section at 32 W G was performed for retro placental hematoma. The neonate was 1400 g healthy girl with an anemia (hemoglobin 9.7 g/dl). After one month of life, the child met a neonatal multifocal hemangioma (skin and liver were involved) with superficial erosion of skin hemangiomas that required post-natal transfusions. We propose a literature review related to the various technics of in utero treatment of placental chorioangioma and the links with neonatal multifocal hemangiomatosis as well. The girl is now 7 year old and has a normal neurodevelopmental outcome.

Effective detection and management of fetal growth restriction is relevant to all obstetric care providers. Models of best practice to care for these patients and their families continue to evolve. Since much of the disease burden in fetal growth restriction originates in the placenta, the concept of a multidisciplinary placenta clinic program, managed primarily within a maternal-fetal medicine division, has gained popularity. In this context, fetal growth restriction is merely one of many placenta-related disorders that can benefit from an interdisciplinary approach, incorporating expertise from specialist perinatal ultrasound and magnetic resonance imaging, reproductive genetics, neonatal pediatrics, internal medicine subspecialties, perinatal pathology, and nursing. The accurate diagnosis and prognosis for women with fetal growth restriction is established by comprehensive clinical review and detailed sonographic evaluation of the fetus, combined with uterine artery Doppler and morphologic assessment of the placenta. Diagnostic accuracy for placenta-mediated fetal growth restriction may be enhanced by quantification of maternal serum biomarkers including placenta growth factor alone or combined with soluble fms-like tyrosine kinase-1. Uterine artery Doppler is typically abnormal in most instances of early-onset fetal growth restriction and is associated with coexistent preeclampsia and underlying maternal vascular malperfusion pathology of the placenta. By contrast, rare but potentially more serious underlying placental diagnoses, such as massive perivillous fibrinoid deposition, chronic histiocytic intervillositis, or fetal thrombotic vasculopathy, may be associated with normal uterine artery Doppler waveforms. Despite minor variations in placental size, shape, and cord insertion, placental function remains, largely normal in the general population. Consequently, morphologic assessment of the placenta is not currently incorporated into current screening programs for placental complications. However, placental ultrasound can be diagnostic in the context of fetal growth restriction, for example in Breus' mole and triploidy, which in turn may enhance diagnosis and management. Several examples are illustrated in our figures and supplementary videos. Recent advances in the ability of multiparameter screening and intervention programs to reduce the risk of severe preeclampsia will likely increase efforts to deliver similar improvements for women at risk of fetal growth restriction. Placental pathology is important because the underlying pathologies associated with fetal growth restriction have a wide range of recurrence risks. Rare conditions such as massive perivillous fibrinoid deposition or chronic histolytic intervillositis may recur in >50% of subsequent pregnancies. Postpartum care in a placenta-focused program can provide effective counseling for modifiable maternal risk factors, and can assist in planning future pregnancy care based on the pathologic basis of fetal growth restriction.

PURPOSE: To evaluate outcomes of uterine conserving surgery with occlusion balloon technique. A critical review of the complications was performed. MATERIALS AND METHODS: Between 2010 and 2016, pregnant women, with a prenatal diagnosis of morbidly adherent placenta (MAP), were treated with occlusion balloon catheters in both internal iliac arteries. Parameters such as need for hysterectomy, incidence of PPH, grade of MAP, estimated blood loss during delivery (EBL) and transfusion requirements, mean recovery time and duration of the balloon inflation, were collected and reviewed. Complications requiring further management were analysed. RESULTS: Thirty-seven women with MAP underwent prophylactic occlusion balloon placement (POBC). Mean recovery was 4.48 days (range 2-10). Catheters were successfully positioned and balloons inflated in obstetric theatre following caesarean delivery in 100% of the cases. The uterus was conserved in every case. The MAP grades were 20 percreta, 3 increta and 14 accreta. The EBL was not statistically different between the different grades of placentation. There was a statistically significant association in the number of patients requiring blood transfusions and the degree of placental invasion (p = 0. 0119). PPH occurred in 5 patients (13.5%) and arterial thrombosis in 4 patients (11%). The EBL during delivery was significantly higher (2811 mL) in patients with complications (p = 0.0102). Furthermore, the group of patients that had complications required statistically significant more blood transfusions compared to those without complications (p = 0.0001). No maternal mortality or foetal morbidity occurred. CONCLUSION: The utilisation of Prophylactic occlusion balloon catheters allows uterine conserving surgery to be performed safely with few maternal complications.

Placental dysfunction underlies major obstetric diseases such as pre-eclampsia and fetal growth restriction (FGR). Whilst there has been a little progress in prophylaxis, there are still no treatments for placental dysfunction in normal obstetric practice. However, a combination of increasingly well-described in vitro systems for studying the human placenta, together with the availability of more appropriate animal models of pre-eclampsia and FGR, has facilitated a recent surge in work aimed at repurposing drugs and therapies, developed for other conditions, as treatments for placental dysfunction. This review: (1) highlights potential candidate drug targets in the placenta - effectors of improved uteroplacental blood flow, anti-oxidants, heme oxygenase induction, inhibition of HIF, induction of cholesterol synthesis pathways, increasing insulin-like growth factor II availability; (2) proposes an experimental pathway for taking a potential drug or treatment for placental dysfunction from concept through to early phase clinical trials, utilizing techniques for studying the human placenta in vitro and small animal models, particularly the mouse, for in vivo studies; (3) describes the data underpinning sildenafil citrate and adenovirus expressing vascular endothelial growth as potential treatments for placental dysfunction and summarizes recent research on other potential treatments. The importance of sharing information from such studies even when no effect is found, or there is an adverse outcome, is highlighted. Finally, the use of adenoviral vectors or nanoparticle carriers coated with homing peptides to selectively target drugs to the placenta is highlighted: such delivery systems could improve efficacy and reduce the side effects of treating the dysfunctional placenta.

PURPOSE: To determine the impact of a structured multi-disciplinary management strategy on clinical outcomes in women with invasive placental disease (IPD). MATERIALS AND METHODS: This was a retrospective cohort study of consecutive women having peripartum hysterectomies with IPD over seven years. For the most recent three years, a structured multidisciplinary team (MDT) reviewed each suspected case, created a management plan, and implemented that plan. Outcomes were compared between cases delivered prior to and after the MDT process was started. RESULTS: There were 47 pregnancies with IPD, of which 31 (66.0%) were suspected antenatally and 40 (85.1%) had a prior uterine surgery. An MDT approach was performed in 19 (40.4%) cases. In the MDT group, there were longer operative times (260 min versus 181 min, p = 0.0001), less blood loss (1200 mL versus 2500 mL, p = 0.009), less administration of blood products (47.4% versus 85.7%, p = 0.005), and higher intraoperative lowest mean arterial pressures (MAPs) (57 mmHg versus 48 mmHg, p = 0.002, when compared to the No-MDT (n = 28) approach. No differences were found for other outcomes. CONCLUSION: Clinically meaningful improvements of less blood loss, fewer transfusions, and higher intraoperative MAPs suggest that MDT cases were more stable intraoperatively, which over a larger number of patients, should translate into improved outcomes.

Resultados: Se hallaron 51 expedientes de pacientes a quiénes se realizó HO de enero de 2012 a noviembre de 2015. La prevalencia fue de 17,1/10.000 nacimientos, la incidencia por año fue de 1,7 (2012), 1,7 (2013), 1,4 (2014) y 1,9 (2015) por cada mil nacimientos respectivamente. La prevalencia de HO post-cesárea fue de 25,6/10.000 y en el post-parto de 10,6/10.000. Las variables que alcanzaron significancia entre cirugía programada y de emergencia fue pérdida sanguínea y necesidad de transfusiones sanguíneas. El procedimiento se asocia a anemia en el puerperio 7 veces más y las principales indicaciones para realizar el procedimiento fueron alteración de la adherencia placentaria e hipotonía. Conclusiones: El diagnóstico prenatal de anomalías en la adherencia placentaria, la mejor utilización de hemoderivados y la técnica quirúrgica ha eliminado la mortalidad materna por hemorragia obstétrica masiva en los últimos cuatro años en el Hospital General Dr. Aurelio Valdivieso.
Objective: To determine the incidence, main indications and complications of obstetric hysterectomy in a secondary hospital care to four years to implement the program of prevention and management of obstetric hemorrhage. Methods: Descriptive study of review of clinical records, transversal, analytical and retrospective. Results: 51 cases of patients who obstetric hysterectomy (OH) was held between January 2012 to November 2015. The prevalence was 17.1/10,000. The incidence per year was 1.7 (2012), 1.7 (2013), 1.4 (2014) and 1.9 (2015) per 1000 births, respectively. The prevalence of post-cesarean OH was 25.6/10,000 while postpartum OH was 10.6/10,000. The variables that reached significance between scheduled and emergency surgery was blood loss and need for blood transfusions. The procedure is associated with anemia in the postpartum period 7 times and the main indications for the procedure were alteration abnormal placental adhesion and uterine atony. Conclusions: The prenatal diagnosis of abnormal placental adhesion, better use of blood products and surgical technique has eliminated maternal mortality by massive obstetric hemorrhage in the last four years in the General Hospital Dr. Aurelio Valdivieso.

OBJECTIVE: To evaluate a protocol for selection of placental polyp management, including expectant management and hysteroscopic resection with or without transarterial embolization (TAE), using power Doppler color score (PDCS) as the vascularity parameter. MATERIALS AND METHODS: This retrospective case-control study included 25 patients who were diagnosed with placental polyps. We evaluated the vascularity of placental polyps with PDCS measured by transvaginal ultrasonography as follows: PDCS 1, no blood flow; PDCS 2, minimal flow; PDCS 3, moderate flow; and PDCS 4, marked blood flow. We then selected expectant management or hysteroscopic resection with or without TAE. RESULTS: Three of 17 patients with PDCS 1 or 2 underwent surgical intervention, and expectant management was successful in 14. Seven of eight patients with PDCS 3 or 4 underwent surgical intervention, while expectant management was successful in only one patient. CONCLUSION: PDCS is a simple examination for evaluating the vascularity of placental polyps. PDCS might be useful for selecting the optimal treatment for placental polyps, such as expectant management or surgical intervention, according to their vascularity.

BACKGROUND: Intraplacental choriocarcinoma (IC) is a rare form of malignant gestational trophoblastic disease (GTD). We present a review of 62 cases, including four previously unreported, and a suggested management algorithm. PATIENTS AND METHODS: IC cases and clinical data were identified within the Charing Cross Hospital (CXH) national GTD database (1986-2014) and by systematic literature search (1949-2014). RESULTS: 62 cases were identified including eight from CXH representing 0.03% of all GTD (n=27,101) diagnosed between 1986 and 2014. Most cases were identified in the third trimester (n=52; 84%) among asymptomatic women (n=31; 50%) and with macroscopically normal placenta in 29% (18/62). In 29 non-metastatic cases with available data, 4 (14%) underwent adjuvant chemotherapy and 25 (86%) surveillance only, one of whom relapsed with metastatic disease cured with multi-agent chemotherapy. In 32 patients with metastatic disease (31 at presentation and one with relapse during surveillance), all 18 treated since 1990 achieved complete remission with multi-agent chemotherapy. Among 58 cases with available data, there were 20 fetal deaths and 38 live births with 2 neonatal deaths. Of the two (5%) cases of infantile choriocarcinoma, one was cured with intensive therapy and the other died shortly after commencing single agent treatment. A further neonatal death was due to fetomaternal haemorrhage. CONCLUSIONS: IC usually occurs in the third trimester and is often asymptomatic with no macroscopic placental abnormalities. Prognosis with current therapy is generally excellent, even for patients presenting with metastatic disease. Around 60% of pregnancies affected by IC result in a live birth with a low neonatal mortality.

Postpartum uterine bleeding is not uncommon and is caused by a variety of obstetrical and gynecological disorders, such as retained placenta, dysfunctional bleeding, and endometrial polyps. Placental polyps and uterine arteriovenous malformation are disorders often encountered in cases of abnormal uterine bleeding in the late puerperal period. These patients may experience life-threatening bleeding and require prompt intervention based on the correct differential diagnosis. The optimal treatments for both diseases differ as follows: intrauterine curettage or transcervical resection are chosen for placental polyps, while total abdominal hysterectomy or uterine artery embolization is preferred for uterine arteriovenous malformation since intrauterine curettage or transcervical resection has the risk of massive bleeding. However, since placental polyp and uterine arteriovenous malformation have similar clinical characteristics, it is important to accurately identify and differentiate between them to ensure optimal therapy. We report here cases that were suggestive of placental polyp or uterine arteriovenous malformation. We discuss the differential diagnoses and treatments for both diseases based on a literature review and propose a novel algorithm for managing such patients.

Blastocyst implantation, placental development, and fetal growth are all dependent on the interactions between the developing placenta and the decidualized endometrium. Adult stem cell populations resident in both the placenta and endometrium play key roles in directing cell fate and tissue organization throughout pregnancy. As we begin to understand how these stem cell populations contribute to successful pregnancies, we can begin to ask what roles they play in the pathogenesis of pregnancy disorders from implantation failure and miscarriage through fetal growth restriction and preeclampsia. Furthermore, as our understanding of the therapeutic applications of stem cells in other organs rapidly expands, can we make stem cell therapies a clinical reality in obstetric medicine? This review aims to summarize our current understanding of the role reproductive stem cells play in pregnancy success, and how they may help us better understand the underlying pathogenesis of pregnancy disorders to offer novel therapeutic solutions in the future.

OBJECTIVE: To assess foetal absorbed radiation dose (FAD) during prophylactic occlusion balloon catheter (POBC) placement before surgery for morbidly adherent placenta (MAP). METHODS: Retrospective cohort study of women with MAP undergoing POBC before surgery. Women were divided into two groups. Group 1 treated between 2008 and 2011, Group 2 between 2012 and 2014 when fluoroscopy pulse rate reduced from 7.5 to 2 pulses per second. Median and interquartile range (IQR) of dose area product (DAP) and FAD were compared using the Mann-U-Whitney test. FAD was calculated using the PCXMC Monte-Carlo calculation. All procedures were performed using the same equipment (Siemens Axiom Artis dTA) by the same experienced interventional radiology team. RESULTS: Thirty-four women underwent POBC. 16 procedures were performed in Group 1 and 18 in Group 2. Median DAP overall was 1025.10 µGym(2) (IQR 532.1-1775.3): Group 1, 1713.25 µGym(2) (IQR 1164.5-2274.5) and Group 2, 660.70 µGym(2) (IQR 440.9-1020.9) (p = 0.027). Median FAD overall was 4.65 mGy (IQR 2.7-8.2): Group 1, 6.25 mGy (IQR 4.4-10.6) and Group 2, 3.05 mGy (IQR 2.0-5.4) (p = 0.031). CONCLUSIONS: FAD during POBC insertion is low overall. The only change between the two groups was in pulsed fluoroscopy rate which resulted in a significant reduction in FAD. This reinforces the importance of implementation of dose reduction techniques.
