ABSTRACT
BACKGROUND:
Mesenteric bypass (MB) for patients with acute (AMI) and chronic mesenteric ischemia (CMI) is associated with cardiovascular (CV) and pulmonary morbidity.METHODS:
Patients with AMI and CMI from 2008 to 2019 were identified to determine independent predictors of CV (cardiac arrest, MI, DVT, and stroke) and pulmonary (pneumonia and ventilator time>48 h) morbidities in patients undergoing MB.RESULTS:
377 patients were identified. Patients with AMI had higher rates of preoperative SIRS/sepsis (28 vs 12%, P < .0001), were more likely to be ASA class 4/5 (55 vs 42%, P = .005), were more likely to require bowel resection (19 vs 3%, P < .0001), and were more likely to have vein utilized as their bypass conduit (30 vs 14%, P < .0001). There were no differences in use of aortic or iliac inflow (P = .707) nor in return to the OR (24 vs 19%, P = .282). Both postoperative sepsis (12 vs 2.6%, P = .003) and mortality (31.4% vs 9.8%, P < .0001) were significantly increased in patients with AMI. After adjusting for both patient and procedural factors, multivariable logistic regression (MLR) identified international normalized ratio (INR) (OR 3.16; 95% CI 1.56-6.40, P = .001) and chronic heart failure (CHF) (OR 5.88; 95% CI 1.15-29.97, P = .033) to be independent predictors of pulmonary morbidity, while preoperative sepsis (OR 1.96; 95% CI 1.45-2.66, P < .0001) alone was predictive of CV morbidity in all patients undergoing MB.DISCUSSION:
Mesenteric bypass for mesenteric ischemia leads to high rates of morbidity and mortality, whether done in an acute or chronic setting. Preoperative sepsis, independent of AMI or CMI, predicts CV morbidity, regardless of bypass configuration or conduit, while elevated INR or underlying CHF carries a higher risk of pulmonary morbidity.Palavras-chave
