Staged extra-anatomic bypass grafting (with axillofemoral bypass graft) and aortic graft removal for treatment of aortic graft infection are associated with acceptable early and long-term outcomes and should remain a primary approach in selected patients with this grave problem.
Thoracoabdominal aortic aneurysm repair results in the increased plasma appearance of TNF-alpha, IL-6, IL-8, IL-10, and shed TNF receptors. The frequency and magnitude of postoperative organ dysfunction after TAAA repair is associated with an increased concentration of the cytokines, TNF-alpha, and IL-6 and the increased plasma levels of these cytokines appear to require extended visceral ischemia times.
The insertion of inferior vena cava (IVC) filters results in device migration at rates that exceed 50% in some studies, although the clinical significance of migration remains in question. These filters can also erode or penetrate the IVC wall, injuring adjacent retroperitoneal and abdominal structures. The risk of erosion or perforation is estimated to be as much as 25%, although clinical symptoms are observed far less frequently in patients with these complications. We describe the presentation, evaluation, and treatment of a patient with an IVC strut protruding into the duodenum. This case report discusses complications, presenting symptoms, and treatment of patients with IVC filters complications.
Survival and good functional outcome after TAAA repair is significantly less common than expected and is primarily predicted with intraoperative factors and postoperative complications. Improved operative techniques and limitation of visceral ischemia reperfusion injury may improve outcome after TAAA repair.
HRQL in patients with PVD correlates weakly with ABI, but exhibits a closer association with vascular symptoms. However, neither variable fully expresses patient HRQL. These data suggest that sole reliance on these surrogates may not accurately reflect the effect of PVD on HRQL, or the potential benefit of vascular surgery in improving HRQL.
The real-world use of the AFX endograft was associated with a low rate of device-and procedure-related complications. The ability to achieve an extended seal zone beyond the anatomical neck might in part contribute to positive outcomes, including the low type Ia and type II endoleak rate. These findings suggest that the AFX device might offer some advantages over other currently marketed endografts, but confirmation awaits the availability of longer-term outcome data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
