To present the surgical management of a patient with a giant isolated superior mesenteric artery dissecting aneurysm complicated by a potential rupture.
Key Findings:
The patient had a giant ISMADA with involvement of distal branches and severe true lumen compression.
At 30-month follow-up, the patient remained asymptomatic without abdominal or gastrointestinal complaints.
Interpretation:
Isolated superior mesenteric artery dissection is rare but can lead to serious complications such as aneurysmal degeneration and rupture. While most uncomplicated cases can be managed conservatively, complex cases may necessitate surgical intervention.
Limitations:
The study is based on a single case report, limiting generalizability to broader populations.
Long-term outcomes beyond 30 months are not reported, which may affect the understanding of the condition's progression.
Conclusion:
Open surgical repair is essential for selected complex cases of ISMADA, despite the feasibility of endovascular therapy in suitable patients.
