To evaluate the association of stenosis of celio-mesenteric and internal iliac arteries with anastomotic leakage (AL) following left-sided colorectal resection in patients with primary colorectal cancer.
Key Findings:
Among 367 left-sided colorectal resections, 37 patients with AL were matched to 60 controls.
Significant stenosis prevalence ranged from 9.3% to 23.7% with good to excellent interrater agreement.
Left internal iliac artery (LII) stenosis was significantly associated with AL (OR 4.13, p=0.026).
No association was found between AL and other assessed arteries.
Interpretation:
LII stenosis is a significant vascular predictor of AL after left-sided colorectal surgery, suggesting the need for preoperative arterial assessment.
Limitations:
Single-center study may limit generalizability.
Sample size for patients with AL was relatively small.
Conclusion:
Incorporating preoperative arterial assessment on routine contrast-enhanced CT may improve risk stratification and guide preventive strategies in selected patients.
