Nutcracker Phenomenon as a Result of Celiomesenteric Trunk Aneurysm

Area of Science:

• Vascular Surgery
• Abdominal Aortic Aneurysm
• Anatomical Variations

Background:

• Congenital anomalies of the celiac trunk and superior mesenteric artery are rare.
• Aneurysms of such common trunks are exceptionally rare.
• Nutcracker phenomenon, or syndrome, is typically associated with renal artery or vein compression.

Observation:

• A patient presented with an aneurysm of the celiomesenteric trunk.
• This rare aneurysm resulted in compression of the left renal vein, mimicking nutcracker phenomenon.
• No prior reports linked this specific aneurysmal anomaly to nutcracker phenomenon.

Findings:

• The celiomesenteric trunk aneurysm was successfully repaired using an endovascular technique.
• Post-procedure imaging and clinical evaluation showed reduced inflammation surrounding the aneurysm.
• Left renal vein compression significantly improved following the endovascular repair.

Implications:

• Endovascular repair is a viable and effective treatment for celiomesenteric trunk aneurysms.
• This case expands the understanding of rare vascular anomalies and their clinical presentations.
• Minimally invasive techniques offer a promising alternative to open surgery for complex vascular repairs.
