Core Tip

Core tip: In this study, we enrolled 154 patients (> 65 years old) who underwent digital subtraction angiography of the inferior mesenteric artery (IMA). The characteristics and perfusion patterns of the IMA were examined. Perfusion regions were cross-referenced with clinical and anatomical features. Our study demonstrated that 25 (16.2%) patients had IMA lesions and the IMA perfusion region stopped at the splenic flexure in 50 (32.5%) elderly patients. The IMA perfusion region was independently associated with IMA atherosclerotic lesion, branching pattern, collateral circulation, and marginal artery integrity. Thus, the applicability and precision of preoperative angiography for evaluating the IMA branching and perfusion patterns could facilitate geriatric laparoscopic left-sided colorectal cancer surgery with suspicion of poor IMA perfusion.
