Uterine arteriovenous malformation (AVM) is a rare but serious condition that can cause heavy uterine bleeding. It occurs when abnormal connections form between the arteries and veins in the uterus, leading to significant health complications. Accurate identification and diagnosis are crucial because overlooking or mishandling them can lead to severe, life-threatening bleeding. We present the case of a 30-year-old patient presenting with abnormal uterine bleeding 15 days after she gave birth to her second child. The ultrasound examination showed images suggestive of retained ovuloplacental remnants, so a uterine aspiration was performed, but the patient presented severe vaginal bleeding. Subsequently, magnetic resonance imaging (MRI) was performed, demonstrating the presence of a prominent lesion in the posterior wall of the uterine body with multiple serpentine-like pathways and a signal void suggestive of aberrant vessels corresponding to AVMs. Ergotrate and misoprostol were administered to control the bleeding, and a Bakri balloon was inserted and maintained until the bleeding stopped. We are highlighting this case to emphasize the importance of considering uterine AVM (UAVM) when dealing with abnormal uterine bleeding, even in the postpartum period. Due to its rarity, there is a lack of substantial evidence to guide clinicians in managing this condition.

Sheehan syndrome is a well-documented endocrinological disorder that appears to be closely associated as a secondary sequela to postpartum hemorrhage. Due to pregnancy-related physiological adaptations, namely the increase in blood volume but lack of hypertrophic or hyperplastic growth within the pituitary, pregnancy increases the likelihood of infarction of the pituitary. This, coupled with other complications, such as postpartum hemorrhage, can lead to ischemia and permanent damage to the pituitary, and thus, all the downstream endocrinological pathways regulated by the pituitary. Namely, this can include, but is not limited to, adrenal crisis from improper stimulation of steroid secretion. Individuals who have been diagnosed with Sheehan syndrome require lifelong steroid supplementation for appropriate regulation of multiple systems, specifically circulatory. Without appropriate steroid supplementation exogenously, patients can rapidly decline with adverse hypotension, altered mental status, and loss of vascular tone. This case presents a case of a patient who, after extensive chart review and history taking, was found to have had a complicated pregnancy many years ago with multiple transfusions needed to stabilize her and was placed on exogenous steroid management, presenting for adrenal crisis, hypotension, and altered mental status after not taking her home steroid medication.

Obstetrical hemorrhage is a relatively frequent obstetrical complication and a common cause of maternal morbidity and mortality worldwide. The majority of maternal deaths attributable to hemorrhage are preventable, thus, developing rapid and effective means of treating postpartum hemorrhage is of critical public health importance. Intrauterine devices are one option for managing refractory hemorrhage, with rapid expansion of available devices in recent years. Intrauterine packing was historically used for this purpose, with historical cohorts documenting high rates of success. Modern packing materials, including chitosan-covered gauze, have recently been explored with success rates comparable to uterine balloon tamponade in small trials. There are a variety of balloon tamponade devices, both commercial and improvised, available for use. Efficacy of 85.9% was cited in a recent meta-analysis in resolution of hemorrhage with the use of uterine balloon devices, with greatest success in the setting of atony. However, recent randomized trials have demonstrated potential harm associated with improvised balloon tamponade use In low resource settings and the World Health Organization recommends use be restricted to settings where monitoring is available and care escalation is possible. Recently, intrauterine vacuum devices have been introduced, which offer a new mechanism for achieving hemorrhage control by mechanically restoring uterine tone via vacuum suction. The Jada device, which is is FDA-cleared and commercially available in the US, found successful bleeding control in 94% of cases in an initial single-arm trial, with recent post marketing registry study described treatment success following hemorrhage in 95.8% of vaginal and 88.2% of cesarean births. Successful use of improvised vacuum devices has been described in several studies, including suction tube uterine tamponade via Levin tubing, and use of a modified Bakri balloon. Further research is needed with head-to-head comparisons of efficacy of devices and assessment of cost within the context of both device pricing and overall healthcare resource utilization.

Magnesium sulfate is used for seizure prophylaxis in preeclampsia and for fetal neuroprotection when delivery is anticipated before 32 weeks of gestation. Existing risk assessment tools for postpartum hemorrhage often identify the use of magnesium sulfate as an intrapartum risk factor. Previous studies examining the association between the use of magnesium sulfate and postpartum hemorrhage have relied largely on qualitative estimates of blood loss rather than quantitative estimates of blood loss.
This study aimed to determine whether intrapartum administration of magnesium sulfate is associated with an increased risk of postpartum hemorrhage using a quantitative blood loss assessment via the use of graduated drapes and weight differences in surgical supplies.
This case-control study was conducted to test the hypothesis that intrapartum parenteral administration of magnesium sulfate is not independently associated with postpartum hemorrhage. All deliveries at our tertiary-level academic medical center between July 2017 and June 2018 were reviewed. Of note, 2 categories of postpartum hemorrhage were defined: the traditional definition (>500 mL for vaginal delivery and >1000 mL for cesarean delivery) and the contemporary definition (>1000 mL regardless of delivery mode). Statistical analyses using the chi-square test, Fisher exact test, t test, or Wilcoxon rank-sum test were performed to compare the patients who did and did not receive magnesium sulfate concerning the rates of postpartum hemorrhage, pre- and postdelivery hemoglobin level, and rates of blood transfusion.
A total of 1318 deliveries were included, with postpartum hemorrhage rates of 12.2% (traditional definition) and 6.2% (contemporary definition). Multivariate logistic regression did not find the use of magnesium sulfate as an independent risk factor by either definition (odds ratio, 1.44 [95% confidence interval, 0.87-2.38] and 1.34 [95% confidence interval, 0.71-2.54]). The only significant independent risk factor was cesarean delivery, by both definitions (odds ratio, 2.71 [95% confidence interval, 1.85-3.98] and 19.34 [95% confidence interval, 8.55-43.72]).
In our study population, intrapartum administration of magnesium sulfate was not found to be an independent risk factor for postpartum hemorrhage. Cesarean delivery was determined as an independent risk factor, consistent with previous reports.

Postpartum hemorrhage is one of the leading causes of maternal mortality worldwide. Uterine atony is the main cause, representing up to 90% of cases, and is a risk factor for uterine inversion. Morbidity and mortality occur in 41% of uterine inversion cases, including massive obstetric hemorrhage. Massive obstetric hemorrhage is a medical emergency that puts life and reproductive function at risk, and therefore, its treatment must be timely and immediate. If there is no favorable response with the initial measures, surgical intervention proceeds. When choosing the surgical procedure, priority should be given to the technique with the easiest access and which is the least invasive, the safest, and in which the surgeon has more experience. We present a case report with our technique of bilateral ligation of the anterior trunk of the hypogastric artery, after a uterine compression suture failed, with excellent results and preserved fertility in an adolescent patient. We describe the technique and the result. The response time of the uterus with normal tone was 5 minutes, and postligation bleeding was only 50 mL after the patient had bled 1200 mL without complications; thus, it is an adequate and cost-effective technique. The bilateral ligation of the anterior trunk of the hypogastric artery technique in the case of postpartum hemorrhage is an effective, safe, and fertility-preserving surgical procedure that constitutes an alternative to emergency obstetrical hysterectomy when other, less invasive methods have failed.

Iron deficiency anemia during pregnancy is a common concern, affecting 38% of women worldwide and up to 50% in developing countries. It is defined differently throughout all 3 trimesters. It has several detrimental effects on pregnancy outcomes for both the mother and the fetus, such as increasing the risk for postpartum depression, preterm delivery, cesarean delivery, preeclampsia, and low birthweight. Management of iron deficiency anemia is done classically via oral iron supplementation. However, recent evidence has shown that intravenous iron is a good alternative to oral iron if patients are unable to tolerate it, not responding, or present with a new diagnosis very late in pregnancy. Management of iron deficiency anemia was demonstrated to be protective against postpartum hemorrhage. Other ways to prevent postpartum hemorrhage include improving prediction tools that can identify those at risk. Several risk assessment kits have been developed to estimate the risk for postpartum hemorrhage among patients and have been proven useful in the prediction of patients at high risk for postpartum hemorrhage despite limitations among low-risk groups. More comprehensive tools are also being explored by determining clinically relevant factors through nomograms, with some proving their efficacy after implementation. Machine learning is also being used to develop more complete tools by including risk factors previously not accounted for. These newer tools, however, still require external validation before being adopted despite promising results under testing conditions.

Obstetrical hemorrhage is the leading cause of maternal morbidity and mortality worldwide, and the rates of severe hemorrhage are increasing. There is a crucial need to expand treatment options for hemorrhage to address this global crisis. Over the last decade, the evolution of hemorrhage control devices has contributed to advancements in obstetrical hemorrhage management. The number of existing hemorrhage control devices and techniques has increased markedly in recent years, and new devices are in development. The current evidence for established and investigational hemorrhage control devices has been summarized in this review. Of note, 2 main categories of devices exist: traditional uterine tamponade and vacuum-induced uterine tamponade. Although traditional intrauterine balloon tamponade devices are currently used widely in postpartum hemorrhage management, novel hemorrhage control devices and techniques have been developed. These include the minisponge tamponade device, the Jada System, a modified Bakri balloon technique, and a suction tube uterine tamponade technique. Reassuring safety data and preliminary efficacy data from pilot studies of these novel techniques support the powerful role intrauterine devices can play in obstetrical hemorrhage management. This review aimed to improve awareness of device options so that continued efforts can be made to integrate new technology into hemorrhage management protocols. Well-designed studies inclusive of new hemorrhage control devices are essential to understanding where new technology fits into preexisting obstetrical hemorrhage algorithms. In addition, access to new tamponade technology remains limited on a global scale. Programs aimed at both increasing access to devices and expanding educational initiatives are essential to make new technology a standard component for hemorrhage management.

The utility of prophylactic endovascular internal iliac balloon placement in the surgical management of placenta accreta spectrum is debated.
In this study, we review outcomes of surgical management of placenta accreta spectrum with and without prophylactic endovascular internal iliac balloon catheter use at a single institution.
This is a retrospective cohort study of consecutive viable singleton pregnancies with a confirmed pathologic diagnosis of placenta accreta spectrum undergoing scheduled delivery from October 2018 through November 2020. In the T1 period (October 2018-August 2019), prophylactic endovascular internal iliac balloon catheters were placed in the operating room before the start of surgery. Balloons were inflated after neonatal delivery and deflated after hysterectomy completion. In the T2 period (September 2019-November 2020), endovascular catheters were not used. In both time periods, all surgeries were performed by a dedicated multidisciplinary team using a standardized surgical approach. The outcomes compared included the estimated blood loss, anesthesia duration, operating room time, surgical duration, and a composite of surgical complications. Comparisons were made using the Wilcoxon rank-sum test and the Fisher exact test.
A total of 30 patients were included in the study (T1=10; T2=20). The proportion of patients with placenta increta or percreta was 80% in both groups, as defined by surgical pathology. The median estimated blood loss was 875 mL in T1 and 1000 mL in T2 (P=.84). The proportion of patients requiring any packed red blood cell transfusion was 60% in T1 and 40% in T2 (P=.44). The proportion of patients requiring >4 units of packed red blood cells was 20% in T1 and 5% in T2 (P=.25). Surgical complications were observed in 1 patient in each group. Median operative anesthesia duration was 497 minutes in T1 and 296 minutes in T2 (P<.001). Median duration of operating room time was 498 minutes in T1 and 205 minutes in T2 (P<.001). Median surgical duration was 227 minutes in T1 and 182 minutes in T2 (P<.05). The median duration of time for prophylactic balloon catheter placement was 74 minutes (range, 46-109 minutes). The median postoperative length of stay was similar in both groups (6 days in T1 and 5.5 days in T2; P=.36).
The use of prophylactic endovascular internal iliac balloon catheters was not associated with decreased blood loss, packed red blood cell transfusion, or surgical complications. Catheter use was associated with increased duration of anesthesia, operating room time, and surgical time.

Although the increased risk for severe illness and adverse pregnancy outcomes associated with SARS-CoV-2 infection during pregnancy is well described, the association of infection with severe maternal morbidity has not been well characterized.
This study aimed to evaluate the risk for severe maternal morbidity associated with SARS-CoV-2 infection during pregnancy.
This was a multicenter retrospective cohort study of all pregnant patients who had a SARS-CoV-2 test done and who delivered in a New York health system between March 1, 2020 and March 1, 2021. Patients with missing test results were excluded. The primary outcome of severe maternal morbidity, derived from the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine example list of diagnoses and complications, was compared between the following 2 groups: patients who tested positive for SARS-CoV-2 during pregnancy and patients who tested negative. Secondary outcomes included subgroups of severe maternal morbidity. Multivariable logistic regression was used to adjust for potential confounders such as maternal demographics, neighborhood socioeconomic status, hospital location, and pregnancy-related complications. A subanalysis was performed to determine if the risk for severe obstetrical hemorrhage and hypertension-associated or neurologic morbidity differed based on the timing of SARS-CoV-2 infection between those who tested positive for SARS-CoV-2 at their delivery hospitalization (ie, active infection) and those who tested positive during pregnancy but negative at their delivery hospitalization (ie, resolved infection).
Of the 22,483 patients included, 1653 (7.4%) tested positive for SARS-CoV-2 infection. Patients with SARS-CoV-2 infection were more commonly Black, multiracial, Hispanic, non-English speaking, used Medicaid insurance, were multiparous, and from neighborhoods with a lower socioeconomic status. Patients with SARS-CoV-2 infection were at an increased risk for severe maternal morbidity when compared with those without infection (9.3 vs 6.5%; adjusted odds ratio, 1.52; 95% confidence interval, 1.21-1.88). Patients with SARS-CoV-2 infection were also at an increased risk for severe obstetrical hemorrhage (1.1% vs 0.5%; adjusted odds ratio, 1.78; 95% confidence interval, 1.04-2.88), pulmonary morbidity (2.0% vs 0.5%; adjusted odds ratio, 3.90; 95% confidence interval, 2.52-5.89), and intensive care unit admission (1.8% vs 0.5%; adjusted odds ratio, 3.29; 95% confidence interval, 2.09-5.04) when compared with those without infection. The risk for hypertension-associated or neurologic morbidity was similar between the 2 groups. The timing of SARS-CoV-2 infection (whether active or resolved at time of delivery) was not associated with the risk for severe obstetrical hemorrhage or hypertension-associated or neurologic morbidity when compared with those without infection.
SARS-CoV-2 infection during pregnancy was associated with an increased risk for severe maternal morbidity, severe obstetrical hemorrhage, pulmonary morbidity, and intensive care unit admission. These data highlight the need for obstetrical unit preparedness in caring for patients with SARS-CoV-2 infection, continued public health efforts aimed at minimizing the risk for infection, and support in including this select population in investigational therapy and vaccine trials.

Heterotopic pregnancy (HP) is an uncommon clinical condition characterized by the coexistence of intrauterine and extra-uterine pregnancies. HP is a diagnostic challenge as the typical methods for the early diagnosis of ectopic pregnancy are confounded by the simultaneous presence of intrauterine pregnancy (IUP). Ruptured HP is a potentially life-threatening obstetric emergency and can result in significant morbidity and mortality. Early diagnosis is the key to a favorable outcome. With the increasing number of patients undergoing artificial reproductive technology (ART), which is an important risk factor for HP, the odds of encountering HP patients are also growing. Anesthesiologists are challenged by the need to manage a bleeding obstetric patient while simultaneously ensuring the safety of the IUP. We present perioperative management of a patient with bleeding ruptured HP for emergency laparotomy who went on to have a successful twin delivery 37w3d via cesarean section.
