BACKGROUND/AIM: The inferior mesenteric arteries (IMA) are occluded in some colorectal cancer patients. This study evaluated the impact of IMA occlusion on the calibre of collateral arteries.
PATIENTS AND METHODS: As an IMA obstruction model, 20 patients who underwent abdominal aortic aneurysm surgery, with ligated, excluded, or embolised IMA, were enrolled. Changes in the calibre of the left colic arteries (LCAs) and marginal arteries after surgeries were evaluated.
RESULTS: The cross-sectional area of the LCA significantly increased after surgery (4.34 mm2 vs. 6.34 mm2, p=0.0009) and that of the marginal artery did not change significantly (2.69 mm2 vs. 3.01 mm2, p=0.33).
CONCLUSION: The calibre of the LCA increased after IMA occlusion. The descending branch of the LCA should be confirmed preoperatively to preserve blood flow during a low tie procedure.
