Alpha gal syndrome, a relative not absolute contraindication to the use of bovine pericardium to close an intracardiac septal defect: a case report

CONCLUSIONS: This case highlights that the use of bovine pericardium and porcine heparin to close septal defects in patients with milder forms of alpha-gal allergy can be considered if other options are not available. Further studies are warranted to investigate the long-term outcomes of such potential alpha-gal containing prostheses and heparin exposure and establish the optimal decision making algorithm and prophylactic regimen.

Antegrade Aorto-Mesenteric Bypass Using a Prefabricated Bovine Pericardium Tube Graft for the Treatment of Chronic Mesenteric Ischemia Complicated With Intestinal Necrosis and Biliary Peritonitis

Chronic mesenteric ischemia (CMI) is a vascular disorder primarily caused by atherosclerosis, resulting in intestinal ischemia. While endovascular treatment has become the primary modality for most patients, open mesenteric revascularization remains crucial for complex cases. We present a case of CMI in a patient with critical ischemia, leading to small bowel necrosis, where the endovascular recanalization failed and a surgical approach was needed. A supraceliac antegrade aortomesenteric bypass...
