Background: Morbidly adherent placentation (MAP) increases the risk for obstetric hemorrhage. Cesarean hysterectomy is the prevalent perioperative approach. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a minimally invasive and relatively simple endovascular procedure to temporarily occlude the aorta and control below diaphragm bleeding in trauma. It has been effectively used to reduce obstetric hemorrhage.

Objectives: To evaluate whether REBOA during cesarean delivery (CD) in women with morbidly adherent placentation is a safe and effective treatment modality.

Methods: We introduced REBOA for CD with antepartum diagnosis of MAP in 2019 and compared these patients (RG) to a standard approach group (SAG) treated in our center over the preceding year, as a control. All relevant data were collected from patient electronic files.

Results: Estimated blood loss and transfusion rates were significantly higher in SAG; 54.5% of SAG patients received four RBC units or more vs. one administered in RG. No fresh frozen plasma, cryoprecipitate, or platelets were administered in RG vs. mean 3.63, 6, and 3.62 units, respectively in SAG. Ten SAG patients (90.9%) underwent hysterectomy vs. 3 RG patients (30%). Five SAG patients (45%) required post-surgical intensive care unit (ICU) admission vs. no RG patients. Bladder injury occurred in five SAG cases (45%) vs. 2 RG (20%). One RG patient had a thromboembolic event. Perioperative lactate levels were significantly higher in SAG patients.

Conclusions: Use of REBOA during CD in women with MAP is safe and effective in preventing massive bleeding, reducing the rate of hysterectomy, and improving patient outcome.

Background: Massive, non-compressible bleeding is a leading cause of preventable trauma mortality. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is a minimally invasive procedure in which a balloon catheter is maneuvered into the aorta to temporarily occlude large vessels and enable stabilization of the exsanguinating patient.

Objectives: To present experiences in assimilating REBOA at a single level 1 trauma center in Israel, to evaluate the technical aspects of the procedure, and to describe patient characteristics and outcomes.

Methods: This retrospective cohort study comprised civilians admitted with hemorrhagic shock to our trauma department who were treated with REBOA between November 2017 and July 2021. Descriptive statistics of the patients, characteristics of the injuries and patient outcomes are presented.

Results: The study included 22 patients (median age 30.1 years, 21 male). The mean systolic blood pressure (SBP) before REBOA inflation was 59.6 ± 11.4 mmHg, and the mean SBP measured after the procedure was 115.2 ± 26.3 mmHg. In 20 patients (91%), the SBP was normalized (> 90 mmHg) shortly after inflation of the balloon, and they survived the treatment in the trauma department; 15 (75%) survived the first 30 days. 

Conclusions: REBOA is an effective method for the initial resuscitation and hemorrhage control of patients with massive, non-compressible bleeding and is relatively easy to assimilate in a hospital. The achievement of immediate normalization of SBP enables medical personnel to correct physiological parameters and obtain accurate imaging before proceeding to the operating theater.
