Perioperative Management and Outcomes of Open Aortic Aneurysm Repair in Ethiopia.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background Aortic aneurysms (AAs) are life-threatening conditions requiring timely surgical intervention. While endovascular repair is most common in high-income countries, open surgical repair (OSR) remains the only option in low-resource settings like Ethiopia. This study aimed to examine patient characteristics, perioperative management, and outcomes of OSR at Tikur Anbessa Specialized Hospital (TASH) in Addis Ababa, Ethiopia. Methods We conducted a retrospective observational study of adult patients who underwent OSR between January 2017 and May 2024. Data were extracted from the operating room (OR) logbook and surgical intensive care unit (SICU) registry using a structured tool. Descriptive statistics summarized patient characteristics and perioperative care, while logistic regression analyses identified predictors of in-hospital mortality and major complications. Statistical significance was set at p < 0.05. Results A total of 45 patients (mean age 54.4 ± 16.3 years; 57.8% female) were included in the study. Most had abdominal aneurysms (88.9%) and underwent elective surgery. In-hospital mortality was 13.3%, and 37.8% experienced major complications, excluding deaths. Acute kidney injury (AKI, 22.2%) and hospital-acquired pneumonia (15.8%) were the most common. Ischemic heart disease (IHD) was notably associated with increased risk of mortality (crude odds ratio (COR) = 9.25; p = 0.080), AKI (COR = 14.57; p = 0.030), and respiratory complications (COR = 27.75; p = 0.009). A cross-clamp time exceeding 90 minutes was significantly associated with increased mortality (COR = 7.75; p = 0.035) and AKI (COR = 7.25; p = 0.013). Elevated baseline serum creatinine (≥1 mg/dL) was also significantly associated with the development of AKI (COR = 22.67; p = 0.006). Conclusion This study highlights the feasibility and challenges of open AA repair in resource-limited Ethiopia. Despite a few cases, younger, low-comorbidity patients reflect selective surgery due to constraints. Shortages in equipment, medications, and ICU beds significantly hindered perioperative monitoring, anesthesia care, and pain management, impacting overall surgical outcomes.
