1A' Surgical Clinic, AHEPA University Hospital, Thessaloniki, Greece.
Summary
A large inferior mesenteric artery aneurysm was incidentally found in a patient with a thoracoabdominal aortic aneurysm. Reconstruction of both aneurysms was necessary due to the inferior mesenteric artery
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Gastrointestinal Anatomy
Background:
- Thoracoabdominal aortic aneurysms require complex surgical management.
- Inferior mesenteric artery (IMA) aneurysms are rare but can be clinically significant.
- Anomalous arterial supply to the gastrointestinal tract necessitates careful preoperative assessment.
Observation:
- Incidental discovery of a large IMA aneurysm during work-up for a thoracoabdominal aortic aneurysm.
- Aortography revealed retrograde filling of celiac and superior mesenteric arteries via a large marginal artery from the IMA aneurysm.
- The IMA demonstrated a dominant blood supply to the abdominal viscera.
Findings:
- Successful reconstruction of the thoracoabdominal aortic aneurysm using a bifurcated aorto-biiliac Dacron graft.
- Revascularization of the IMA was performed with a PTFE graft.
- The case underscores the critical role of preoperative angiography in identifying complex arterial anatomy.
Implications:
- Highlights the importance of considering IMA aneurysms in patients with thoracoabdominal aortic pathology.
- Emphasizes the necessity of surgical reconstruction for dilated IMAs with dominant visceral supply.
- Provides a case example for surgical planning in complex aortic and visceral artery aneurysms.
