Midwestern Vascular 2022 was held in Grand Rapids, MI September 15th – 17th.  

Dr. Drew J. Braet presented “A Novel Risk Calculator to Identify Patients at Risk of Contrast Associated Acute Kidney Injury after Endovascular Abdominal Aortic Aneurysm Repair” which outlined a simple and novel risk calculator to identify patients at risk of contrast-associated-acute kidney injury after Endovascular abdominal aneurysm repair (EVAR.) Patients with a glomerular filtration rate < 30, maximum abdominal aortic aneurysm diameter > 6.9 cm, and females who are undergoing EVAR may benefit from pre-operative hydration or use of non-iodinated contrast agents. Prospective studies are needed to determine the efficacy of our model and pre-hydration protocol. Co-authors are Drs. Jeremy Albright, Nicholas H. Osborne, and Peter K. Henke.

Dr. Margaret Smith presented the poster “Delays to Surgery Increase Mortality and Limb Loss in Patients with Acute Limb Ischemia Treated with Open Thrombectomy.” The study concluded that acute limb ischemia requiring surgical thrombectomy has significant morbidity and mortality. Delays from admission to incision and direct oral anticoagulants (DOAC) use were associated with decreased amputation-free survival at one year. Further study into why DOACs but not Warfarin impacted outcomes negatively is indicated in this patient population. Co-authors were Drs. Jeremy Albright, Jonathan Eliason, Loay Kabbani, M Ashraf Mansour, Nicholas H. Osborne, and Peter K. Henke. You can view the poster on our website.

Dr. Abdul Kader Natour presented “Utilization of Preoperative Vein Mapping in Patients Undergoing Infra-Inguinal Bypass is Associated with Increased Use of Venous Conduits.” The study concluded that most patients do not have perioperative vein mapping (PVM) before their Infra-Inguinal Bypass (IIB.) Patients who undergo PVM are more than twice as likely to have a venous conduit used for their bypass. In patients who underwent autogenous venous conduit bypass, post-operative imaging to establish technical adequacy was performed more frequently in patients who underwent PVM and was more likely to be reported as normal. Despite no change in 30-day or 1-year patency, PVM may be a marker for physicians who are interested in best practices for IIB. Co-authors are Drs. Alexander Shepard, Timothy Nypaver, Robert Cuff, Nicolas J Mouawad, Mark Mattos, Peter Henke, and Loay Kabbani.
