    Background: Spontaneous isolated celiac artery dissection (SICAD) is uncommon, with very few series reported in the literature. The present study aims to describe the clinical characteristics and treatment outcomes of patients with SICAD treated at a single Chilean institution over 20 years. Methods: A retrospective review of all patients from a single academic hospital with SICAD diagnosed between January 2003 and March 2023 was performed. Conservative treatment included antiplatelets, anticoagulation, or both. The normal size of a celiac artery in our population was 7.9 +/- 0.79 mm in females and 8.3 +/- 1.08 mm in males. We defined a celiac artery with a diameter equal to or more than 12.5 mm as an aneurysmal celiac artery. Results: The cohort included 27 patients; 77.8% (n = 21) were males. The median age was 51.0 years (range: 38-84 years). Fourteen (51.8%) patients presented with aneurysmal dilatation. Fourteen (51.8%) patients were treated with antiplatelets, 6 (22.2%) patients with anticoagulation, and 7 (25.9%) with anticoagulation and antiplatelets. One patient was treated with endovascular therapy due to a pseudoaneurysm of the celiac artery detected 10 days after conservative treatment with antiplatelets. The median length of hospital stay was 5 days (range: 214 days). Complete remodeling was seen in 6 (22.2%) patients, partial remodeling in 10 (37.0%) patients, and no change was seen in 8 (26.9%) patients. Three (11.5%) patients were lost to follow-up. There were no significant differences between treatments and remodeling outcomes (P = 0.729). The median celiac artery diameter of patients with aneurysmal dilatation was 13.5 mm (range: 12.5-20.5 mm). Systemic arterial hypertension was found more commonly in patients who presented with aneurysmal dilatation than in patients without (87.5% vs. 12.5%, respectively, P = 0.016). Mean follow-up was 41.5 months and median follow-up was 16 months (range: 6-204 months). Conclusions: Most patients with SICAD can be treated conservatively with excellent outcomes. Hypertension was more commonly found in patients with SICAD and aneurysmal dilatation.
