Abdominal aorta balloon occlusion (AABO) has been increasingly adopted as a strategy to reduce intraoperative blood loss during cesarean section. This study aims to evaluate the effectiveness and safety of AABO during cesarean delivery in women with PAS disorders. Materials and Methods: A systematic review and meta-analysis of studies published in English from 2015 to April 2025 was conducted using the following databases: Embase, Scopus, PubMed, Google Scholar, and Web of Science. Articles that met inclusion criteria focused on human participants, original studies, female participants, and studied the efficacy of AABO on blood loss during cesarean delivery for PAS. Articles that were reviews, case reports, other occlusion procedures, and animal studies were excluded. Risk of bias was evaluated using the Newcastle-Ottawa Scale. Results: Twenty-four studies comprising 1958 cesarean deliveries with AABO and 1791 without AABO met the inclusion criteria. Data on blood loss, transfusion, hysterectomy, maternal complications, and neonatal outcomes were extracted, synthesized, and analyzed. The majority of studies (91.6%) applied the balloon at the infrarenal level. Cesarean delivery with AABO resulted in substantially lower mean blood loss (1231 \u00b1 688 mL vs. 2253 \u00b1 857 mL, p &lt; 0.001) and reduced requirements for blood transfusion compared with cesarean delivery alone. Hysterectomy rates were threefold lower with AABO (7.8% vs. 25.8%, p &lt; 0.001), and the incidence of hemorrhagic shock and re-laparotomy were markedly reduced. Complications associated with AABO, including lower limb arterial thrombosis and fever, were uncommon and generally manageable. Conclusions: AABO during cesarean delivery for PAS disorders is associated with reduced intraoperative blood loss, lower transfusion requirements, and decreased hysterectomy rates, suggesting improved maternal hemodynamic stability. Although the procedure is generally safe, vigilance for vascular and thromboembolic complications is essential, and preventive strategies should be incorporated into perioperative care. These findings support the integration of AABO into multidisciplinary management protocols for women with PAS disorders. Future randomized prospective studies should be performed to improve patient selection criteria, standardize the protocols, and further evaluate the long-term maternal and neonatal safety\/outcomes of the procedure.<\/jats:p>","DOI":"10.3390\/jcm15093400","type":"journal-article","created":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T12:31:56Z","timestamp":1777465916000},"page":"3400","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Assessment of Abdominal Aorta Balloon Occlusion Efficiency and Safety in Patients with Placenta Accreta Spectrum Disorder: A Systematic Review and Meta-Analysis"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9196-1496","authenticated-orcid":false,"given":"Meruyert","family":"Abdukassimova","sequence":"first","affiliation":[{"name":"Department of Surgery, School of Medicine, Nazarbayev University, 010000 Astana, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2868-4497","authenticated-orcid":false,"given":"Gulzhanat","family":"Aimagambetova","sequence":"additional","affiliation":[{"name":"Department of Surgery, School of Medicine, Nazarbayev University, 010000 Astana, Kazakhstan"},{"name":"Clinical Academic Department of Women\u2019s Health, CF \u201cUniversity Medical Center\u201d, 010000 Astana, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3914-5154","authenticated-orcid":false,"given":"Milan","family":"Terzic","sequence":"additional","affiliation":[{"name":"Department of Surgery, School of Medicine, Nazarbayev University, 010000 Astana, Kazakhstan"},{"name":"Clinical Academic Department of Women\u2019s Health, CF \u201cUniversity Medical Center\u201d, 010000 Astana, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-9683-5726","authenticated-orcid":false,"given":"Altynshash","family":"Rakhat","sequence":"additional","affiliation":[{"name":"School of Medicine, Nazarbayev University, 010000 Astana, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karlygash","family":"Togyzbayeva","sequence":"additional","affiliation":[{"name":"Clinical Academic Department of Women\u2019s Health, CF \u201cUniversity Medical Center\u201d, 010000 Astana, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lyazzat","family":"Saidildina","sequence":"additional","affiliation":[{"name":"Clinical Academic Department of Women\u2019s Health, CF \u201cUniversity Medical Center\u201d, 010000 Astana, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8344-7873","authenticated-orcid":false,"given":"Gauri","family":"Bapayeva","sequence":"additional","affiliation":[{"name":"Clinical Academic Department of Women\u2019s Health, CF \u201cUniversity Medical Center\u201d, 010000 Astana, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bapayeva, G., Aimagambetova, G., Kadroldinova, N., Zemlyanskiy, V., Kassymbek, K., and Terzic, M.
