Spontaneous isolated superior mesenteric artery dissection: A case report and brief analysis

This case report describes the clinical presentation, diagnostic approach, and treatment strategies for a 58-year-old male patient diagnosed with spontaneous isolated superior mesenteric artery dissection (SISMAD). The patient presented with suddenonset abdominal pain and was diagnosed with SISMAD using computed tomography angiography (CTA). SISMAD is a rare but potentially serious condition that can lead to bowel ischemia and other complications. Management options include surgery, endovascular therapy and conservative management with anticoagulation and close observation. The patient was managed conservatively with antiplatelet therapy and close follow-up. During hospitalization, he received antiplatelet therapy and was closely monitored for signs of bowel ischemia or other complications. The patients' symptoms gradually improved over time, and he was eventually discharged on oral mono- antiagreggation therapy. Clinical follow-up showed a significant symptimatic improvement. Conservative management with antiplatelet therapy was chosen due to the absence of bowel ischemia signs and overall stable clinical condition of patient. This report emphasizes the importance of prompt recognition and management of SISMAD to prevent potentially life-threatening complications. Conservative management with antiplatelet therapy can be a safe and effective treatment option for SISMAD, especially in cases without evidence of bowel ischemia or other complications.
