Summary: Placenta accreta spectrum (PAS) can occur in subsequent pregnancies after uterine artery embolization (UAE), particularly in cases with placenta previa. This case report describes a woman who had undergone UAE and developed placenta previa in her subsequent pregnancy, ultimately being diagnosed with uterine body PAS and requiring hysterectomy.

Summary: The study aims to provide an evidence-based intra-operative protocol for placenta accreta spectrum management. The results showed that although operative times were longer and general anesthesia was more likely to be used, blood loss was reduced and overall blood transfusion rates and rates of massive blood transfusion were significantly decreased. Postoperative complication rates remained unchanged, and neonatal outcomes were equivalent. Therefore, this protocol is an effective approach to manage placenta accreta spectrum, resulting in improved perioperative outcomes and reduced maternal morbidity.

Summary: This article reports a case in which uterine artery balloon occlusion was used instead of uterine artery embolization for hysteroscopic resection of retained products of conception. The surgery was successful and the patient conceived and gave birth to a live baby after the procedure, proving the benefits of uterine artery balloon occlusion.

Summary: In patients with placenta accreta spectrum (PAS), prophylactic balloon occlusion (PBO) procedures such as PBO of the abdominal aorta, common iliac artery, and internal iliac artery significantly reduce blood loss volume. Among these procedures, PBO of the abdominal aorta is the most effective in reducing blood loss volume.

Summary: The study examined the effectiveness and safety of prophylactic internal iliac artery balloon occlusion for hemorrhage control in placenta accreta. Results showed no significant differences between the internal iliac artery balloon occlusion group and the control group in blood loss, packed RBCs transfused, intensive care unit admission, hysterectomy, urinary system injury, Apgar score at 5 min, and neonatal intensive care unit admission. Further large randomized controlled studies are needed to confirm these findings.

Summary: This study compares the outcomes of surgical management of placenta accreta spectrum with and without the use of prophylactic endovascular internal iliac balloon catheters. The results show that the use of catheters is not associated with decreased blood loss, packed red blood cell transfusion, or surgical complications, but is associated with increased duration of anesthesia, operating room time, and surgical time.

Summary: This study retrospectively reviewed the clinical and MRI features of 80 patients with placenta accrete spectrum (PAS) disorders after abdominal aortic balloon occlusion (AABO) and identified risk factors of MRI for association with adverse maternal outcome. The study found that short cervical length (OR: 4.344), abnormal intraplacental vascularity (OR: 6.005), placental bulge (OR: 9.085), and myometrial interruption (OR: 9.550) were independent risk factors for adverse maternal outcomes.

Summary: Placenta accreta spectrum (PAS) refers to the situation where the placental villi are attached or penetrate into the myometrium. A multidisciplinary strategy is crucial for cesarean delivery with PAS. This study demonstrated two cases of intraoperative embolization without hysterectomy in a hybrid operating room for cesarean delivery with placenta accreta. The results showed that intraoperative uterine artery embolization with a hybrid suite is a time-preserving and safe method for cesarean delivery with PAS.

Summary: PBOIIA does not significantly reduce intraoperative blood loss and hysterectomy rate in patients with placenta previa and accreta, but it can reduce the amount of PRBCs transfused. However, PBOIIA significantly increases the financial cost for patients.

Summary: The combined approach of balloon occlusion and uterine artery embolization improves the coagulation function in patients with high-risk placenta previa during cesarean section, reducing blood loss and plasma injection volume, and shortening the hospital stay. This approach has wide clinical application potential.

Summary: This study evaluated the role of resuscitative endovascular balloon occlusion of the aorta (REBOA) in hemorrhage control in patients with abnormally invasive placenta (AIP). The study found that patients who underwent REBOA had less blood loss during cesarean section, higher uterine preservation rate, lower admission to intensive care unit, and shorter operating time.

Summary: Repeatable and sensitive end points are crucial in PAH for clinical practice and therapy trials. This study showed excellent repeatability for MRI and fair treatment effect sizes for the 6 min walk test and log(10)NT-proBNP in PAH patients. The large treatment effect size of MRI-derived right ventricular ejection fraction supports further evaluation of MRI as a non-invasive end point for PAH therapy trials.

Summary: Non-invasive imaging modalities are commonly used in clinical practice, and recent advances in machine learning techniques have shown promise for improving imaging analysis in esophageal cancer patients. Machine learning can assist with diagnosis, treatment response evaluation, prognostication, and investigating biological heterogeneity. Recommendations include improving study design and conducting large multi-center studies for greater generalizability.

Summary: Elevated T1 mapping and ECV values were found in patients with pulmonary arterial hypertension (PAH), especially at the RV insertion points. These values were higher than those in cardiomyopathies and were associated with poor right ventricular function and dilatation.

Summary: This study investigated the prognostic value of patterns of right ventricular adaptation in patients with pulmonary arterial hypertension (PAH) using cardiac magnetic resonance imaging. The results showed that patients in different volume/mass groups had different survival outcomes, with those in the high-volume-low-mass group having a higher risk of treatment failure.

Summary: This study aimed to assess the prognostic value of cardiac magnetic resonance imaging (CMR) as a gold standard imaging technique for evaluating cardiac structure and function in chronic thromboembolic pulmonary hypertension (CTEPH). The results showed that CMR metrics reflecting cardiac function and left heart disease have significant prognostic value in CTEPH. Left atrial volume index (LAVI) was found to predict outcome in patients undergoing pulmonary endarterectomy (PEA), while right ventricular ejection fraction percentage predicted (RVEF%pred) predicted outcome in patients not undergoing PEA. Therefore, considering left heart disease is important in patients being considered for PEA.

Summary: This study quantitatively analyzed CT pulmonary angiography to assess the volumes of peel pulmonary vessels and small pulmonary vessels in different subtypes of pulmonary hypertension (PH). The results showed that the volume of small pulmonary vessels is reduced in pulmonary arterial hypertension and PH associated with left heart disease, while the volume of peel vessels is similar to that of the control group. In patients with PH, the volume of small pulmonary vessels is correlated with pulmonary function tests.

Summary: This cross-sectional study investigated the association between computed tomography (CT)-derived pulmonary vessel volume and the severity of pulmonary hypertension (PH) and disease etiology in patients with chronic lung disease (CLD). The results showed that patients with severe PH-CLD had lower small pulmonary vessel volume compared to those with mild to moderate PH-CLD, regardless of etiology. This reduction in vessel volume was associated with higher mortality.
