Abstract
Gastrointestinal involvement is common in systemic sclerosis (SSc), but severe abdominal pain should not be attributed automatically to dysmotility or malabsorption. We report a 72-year-old woman with long-standing limited cutaneous SSc who developed recurrent severe abdominal pain, progressive oral-intake limitation, and marked weight loss. Abdominal computed tomography angiography showed high-grade calcified stenosis at the superior mesenteric artery (SMA) origin together with a reduced aortomesenteric angle of 17 degrees and a distance of 4.7 mm, creating a coexisting SMAS-like anatomic context. After multidisciplinary review, endovascular balloon angioplasty and stent implantation were performed because the SMA lesion was considered a major treatable vascular contributor in a frail patient at high operative risk. Severe pain improved and oral intake advanced after revascularization, but portal-hypertensive disease, partial small-bowel obstruction, severe malnutrition, and SSc-related gastrointestinal involvement remained plausible concurrent contributors. Follow-up CTA in March 2024 showed post-stent changes without recurrent acute mesenteric ischemia, but long-term stent-patency and nutritional-recovery data were limited. This case does not establish a new causal mechanism; rather, it illustrates a structured approach to severe abdominal pain in SSc that distinguishes a treatable vascular lesion from SMAS-like anatomy and other nonvascular abdominal disease.
