Management of placenta accreta spectrum disorders in COVID 19 patients.

INTRODUCTION: The COVID-19 pandemic has made it difficult to respond to demands in maternal health around the world. Placenta accreta spectrum (PAS) is one of the most severe obstetric conditions and usually requires the use of multiple health resources We describe the clinical results of the management of PAS patients during the COVID-19 pandemic and analyze how the pandemic may affect the functioning of a PAS team. METHODOLOGY: This was a descriptive, retrospective study including all patients treated for PAS in two low- to middle-income country reference hospitals between January 2020 and March 2021. The clinical results of patients with SARS-CoV-2 infection during PAS surgery (Group 1) were compared with those of PAS patients without SARS-CoV-2 infection (Group 2). RESULTS: One hundred forty-five patients undergoing surgery for PAS were included. Group 1 patients (11 cases) showed a longer operative time (250 min, IQR 200-300) and a higher frequency of intra- or postoperative complications (54.5%) than group 2 patients (180 min [IQR 125-240], and 17.9%). CONCLUSION: Placenta accreta spectrum patients undergoing surgery during acute SARS-CoV-2 infection have a higher frequency of postoperative complications. PAS teams must prepare to modify their management protocols to minimize risks for patients and healthcare personnel.

Increasing volume and the role of gynecologic oncologists in peripartum hysterectomies – A single center study of 109 cases over 7 years (008)

Objectives: To evaluate the surgical volume, surgical outcomes, and the evolving role of gynecologic oncologists in peripartum hysterectomies (PPH). Methods: We conducted an IRB-approved retrospective chart review of PPH cases performed at our institution from June 1, 2014, to June 30, 2021. Clinical-pathologic information was ed into a REDCap database. All analyses were conducted using STATA 17. Results: A total of 109 cases were performed over the 7-year period. Gynecologic oncologists (GYO) involvement in the cases increased from 33% in 2014 to 80% in 2021. The mean age was 36 (range: 23-47) years. Most patients were White (81/109, 74.3%), and the median BMI was 30.7 (range: 21-57) kg/m2. Surgical indications included placenta accreta syndrome (PAS) in 84 (77%) cases, uterine atony in ten (9.2%), uterine rupture in three (2.8%), malignancy in five (4.6%), and hemorrhage other than atony in seven cases (6.4%). Intraoperative complications included bladder injury (or intentional dissection) in eight (7.3%), ureter injury in four (3.7%), vascular injury in three (2.8%), and femoral pseudoaneurysm in one (0.9%) of the cases. Postoperative complications included urinary tract infection in 11 (10.1%), nerve injury in one (0.9%), surgical site infection in 13 (11.2%), and venous thromboembolism in five (4.6%) cases. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) usage started in 2019 with one case followed by six cases in 2020 (31.6%) and 3/16 cases in the first half of 2020 (15.8%). A higher REBOA usage in 2020 corresponded with blood products shortages during the COVID crisis.[Formula presented] Conclusions: Overall volume and complexity of peripartum hysterectomy are increasing. This trend is likely driven by an increased incidence of placenta accreta syndrome cases. Gynecologic oncologists are increasingly delegated as primary surgeons in many institutions. Fellowship training programs should strongly consider training in peripartum hysterectomy for trainees.

The Risk of Obstetrical Hemorrhage in Placenta Praevia Associated with Coronavirus Infection Antepartum or Intrapartum.

Background and Objectives: The aim was to evaluate the severity of obstetrical bleeding in the third trimester associated with COVID infection in placenta previa and accreta. Materials and Methods: A retrospective study was conducted to compare the risk of obstetrical bleeding in the case of placenta previa with or without associated SARS-CoV-2 infection. Patients presenting with placenta previa before labor were classified into three groups: group A (control) as no infection throughout their pregnancy, group B as confirmed infection during the 1st trimester, and group C as confirmed infection at the time of delivery. Infected patients were stratified according to the severity of signs and symptoms. The severity of obstetrical hemorrhage at birth was assessed quantitatively and qualitatively. All placentas were analyzed histologically to identify similarities. Results: Prematurity and pregnancy-induced hypertension appear significantly related to SARS-CoV-2 infection during the 3rd trimester. Placenta accreta risk increases significantly with infection during the 1st trimester. No statistically significant differences in the severity of hemorrhage associated with childbirth in cases with placenta previa between groups A and C but increased obstetrical bleeding mainly due to emergency hemostatic hysterectomy in group B driven by placenta accrete were detected. Obstetrical hemorrhage at birth in the case of coexistence of the infection was found not to correlate with the severity of the viral disease. Meanwhile, the number of days of hospitalization after birth is related to the specific treatment of COVID infection and not related to complications related to birth. Conclusions: The study finds an increased incidence of placenta accreta associated with placenta previa in cases where the viral infection occurred in the first trimester of pregnancy, associated with an increased incidence of hemostasis hysterectomies in these patients. Placental histological changes related to viral infection are multiple and more important in patients who had COVID infection in the first trimester.

Life After Amsterdam: Placental Pathology Consensus Recommendations and Beyond.

The Amsterdam Placental Workshop Group Consensus Statement on Sampling and Definitions of Placental Lesions has become widely accepted and is increasingly used as the universal language to describe the most common pathologic lesions found in the placenta. This review summarizes the most salient aspects of this seminal publication and the subsequent emerging literature based on Amsterdam definitions and criteria, with emphasis on publications relating to diagnosis, grading, and staging of placental pathologic conditions. We also provide an overview of the recent expert recommendations on the pathologic grading of placenta accreta spectrum, with insights on their clinical context. Finally, we discuss the emerging entity of SARS-CoV2 placentitis.
