Active clinical trials for "Placenta Accreta"

To evaluate the effectiveness of conservative techniques for placenta accreta spectrum to reduce maternal mortality and morbidity

The study objective is the significance of the ultrasound detection of the paracervical pouch in placenta accreta spectrum. It aimed to evaluate its relation to the degree of placenta accreta spectrum, amount of the blood loss and the number of packed red blood cells transfused.

Placenta accreta is defined as abnormal trophoblast invasion of part or the entire placenta into the myometrium of the uterine wall. Placenta accreta spectrum (PAS), formerly known as morbidly adherent placenta, refers to the range of pathologic adherence of the placenta, including placenta increta, percreta, and accreta. An important risk factor of placenta accreta is placenta previa in the presence of a uterine scar. Placenta previa is an independent risk factor for placenta accreta.Additional reported risk factors for placenta accreta include increased maternal age and multiparity, other prior uterine surgery, prior uterine curettage,uterine irradiation, Asherman syndrome, uterine leiomyomata, uterine anomalies, hypertensive disorders of pregnancy and smoking. (1,2) Maternal morbidity and mortality can occur because of severe and sometimes life-threatening hemorrhage, which often requires blood transfusion also and rates of maternal death are increased for women with PAS. Additionally, patients with PAS are more likely to require hysterectomy at the time of delivery or during the postpartum period and have longer hospital stays states.(3) According to FIGO Classification of PAS Disorders 2019 There are three grades. Grade 1: abnormally adherent placenta (placenta adherent or accreta) - attached directly to the surface of the middle layer of the uterine wall (myometrium) without invading it, Grade 2: abnormally invasive placenta (increta) - invasion into the myometrium and Grade 3: abnormally invasive placenta (percreta) invasion may reach surrounding pelvic tissues, vessels and organs.(4) Nowadays, fertility sparing and conservative methods can be applied. These methods include placenta left in situ, cervical inversion technique , triple-P procedure, cervico-isthmic compression suture and anterior wall uterine resection

The goal of this study is to present the Jakarta Surgical Uterine Conservation (JSICA) technique and its perioperative outcomes in Placenta Accreta Spectrum patients. Participants are all patients undergoing standard hysterectomy or the Jakarta Surgical Uterine Conservation (JSICA) technique. Researchers will compare both groups to see if there are any differences in the perioperative outcomes.

placenta accreta spectrum incidence and outcome

Placenta accreta spectrum (PAS) disorders are associated with increased maternal morbidity and mortality related to life-threatening hemorrhage, and greater potential need for blood transfusion. Clinical evidences have confirmed that the use of autologous blood cell transfusion is safe and effective for patients with obstetric haemorrhage. Normal saline is the solution recommended for red cell washing, administration and salvage. However, there is growing concern that normal saline is more toxic than balanced, buffered crystalloids such as Lactated Ringer's and Plasma-Lyte. The purpose of this study is to evaluate the blood components using of Ringer's Lactated by a prospective, single-center, open, and single-arm clinical trial.

The purpose of this pilot study is to determine if intravenous tranexamic acid (TXA) is effective for reducing blood loss during high risk surgical procedures related to placenta previa and placenta accreta. TXA is currently used in other types of surgery for patients who are expected to have a large blood loss, such as orthopedic or open heart surgery.

Netrin-1 is a secreted protein, which was first identified as a neuronal guidance factor. It is expressed in a multitude of tissues as pancreas, lung, breast, and placenta. Netrin-1 is a multifunctional protein, involved in cell polarity, adhesion, angiogenesis, apoptosis, migration, morphogenesis, and differentiation of various cell types. Most of netrin-1 activity occur through signaling pathways induced by its two main receptors, DCC (deleted in colorectal cancer) and UNC5H (uncoordinated-5 homolog). Its receptors have been linked to the processes of apoptosis and angiogenesis. In absence of netrin-1, DCC and UNC5H receptors lead to apoptosis. In contrary, in presence of netrin-1, receptors transduce molecular cascades leading to proliferation, differentiation and migration of the cells. Netrin-1 has been involved in the pathogenesis of multiple diseases, as diabetes, cardiovascular diseases, and cancer. Serum Netrin-1 levels were high in preeclamptic patients.

Placenta accreta is a relatively rare event, in which the placenta is abnormally implanted into the uterine myometrium. The most significant complication is intense bleeding, mainly during labor. The most important risk factors are previous cesarean delivery, placenta previa, and advanced maternal age. Cesarean hysterectomy is the recommended management. During the recent years, inserting intravascular balloon catheter for occlusion and/or arterial embolization, was introduced as an adjuvant therapy in order to minimize blood loss during cesarean hysterectomy or in conduct with conservative management with the intent of avoiding hysterectomy in selective cases. Contradicting reports exist regarding the effectiveness and safety of the catheters in cases of placenta accreta. The objective of this study is to estimate the efficacy of the balloon catheters among women diagnosed with a placenta accreta.

To assess the 'separation sign' as a predictor of normal placental separation in a large cohort of women at risk for placenta accrete spectrum and in a high-risk subgroup with placenta previa or anterior low-lying placenta and have history of at least one previous Cesarean delivery.
