Preoperative coronary interventions for preventing acute myocardial infarction in the perioperative period of major open vascular or endovascular surgery.

Background: Postoperative myocardial infarction (POMI) is associated with major surgeries and remains the leading cause of mortality and morbidity in people undergoing vascular surgery, with an incidence rate ranging from 5% to 20%. Preoperative coronary interventions, such as coronary artery bypass grafting (CABG) or percutaneous coronary interventions (PCI), may help prevent acute myocardial infarction in the perioperative period of major vascular surgery when used in addition to routine perioperative drugs (e.g.

Endoluminal interventions versus surgical interventions for stenosis in vein grafts following infrainguinal bypass.

Background: Bypass surgery using a large saphenous vein graft, or another autologous venous graft, is a well-recognised treatment option for managing peripheral arterial disease of the lower limb, including chronic limb-threatening ischaemia (CLTI) and intermittent claudication, peripheral limb aneurysms, and major limb arterial trauma. Bypass surgery has good results in terms of limb preservation rates and long-term graft patency but is limited by the possibility of vein graft failure due to stenoses of the graft. Detection of stenoses through clinical and ultrasonographic surveillance, followed by treatment, is used to avoid graft occlusion.

Early experience with off-the-shelf endografts using a zone 0 proximal landing site to treat the ascending aorta and arch.

Objective: Acute type A aortic syndromes and its chronic complications are fatal diseases traditionally treated by open surgery, with high mortality rates. An endovascular approach to the ascending aorta could reduce the morbidity and mortality associated with open surgery. Our aim was to report our initial experience in treating ascending aortic pathology using commercially available descending thoracic endografts.

Stenosis of reverse great saphenous vein graft in infrainguinal arterial revascularization.

Objective: The aim of this study was to evaluate the prevalence of hemodynamically significant infrainguinal bypasses stenosis using reverse great saphenous vein graft.

Methods: From March of 2008 to March of 2009, 56 infrainguinal bypasses were performed with reverse great saphenous vein graft in 56 patients. On the 30th post-operative day, 32 out of 56 patients were submitted to vascular ultrasonography.
