ess. However, no significant difference was found in the incidence of major bleeding between the two access sites. Planned SFA access should be considered as an alternative to CFA access.

SFA access was associated with a higher overall rate of hematoma compared with CFA access. However, no significant difference was found in the incidence of major bleeding between the two access sites. Planned SFA access should be considered as an alternative to CFA access.

Despite the continuing controversy of covered stents (CS) vs bare metal stents, the use of CS in mesenteric occlusive disease (MOD) has been recommended by expert centers. The aim of this study was to report midterm results with CS of the superior mesenteric artery.

Between January 2014 and October 2019, patients with MOD with a severe atheromatous stenosis or occlusion of the superior mesenteric artery treated by mesenteric CS were included. Clinical presentation included both acute mesenteric ischemia (AMI), chronic mesenteric ischemia, and asymptomatic patients planned for major surgery. Demographics, procedure details, and follow-up data were prospectively collected and retrospectively reviewed. Study end points included primary patency, primary assisted patency, and secondary patency.

During the study period, 86 patients (mean age, 70± 9years; 57% males) were included. Clinical presentation was AMI (n= 42 [49%]), chronic mesenteric ischemia (n= 31 [36%]), and asymptomatic (n= 13 [15%]). The technic 76%± 13%), 95% (95% CI, 95%± 8%) and 95% (95% CI, 95%± 8%), respectively.

Mesenteric CS provide very satisfactory midterm results in patients with MOD, with an excellent primary assisted patency rate at 2years, at the price of a significant reintervention rate.

Surgical frailty and its assessment have become essential considerations in perioperative management for the modern aging surgical population. The risk analysis index is a validated frailty score that has been proven to predict short-term outcomes and long-term mortality in several surgical subspecialties and high-risk procedures. We examined the association of risk analysis index scores with postoperative outcomes in a retrospective nationwide database of patients who underwent lower extremity amputation in the Veterans Health Administration Health Care System.

The Veteran Affairs Surgical Quality Improvement Program data was queried across the Veteran Affairs Health Care System with institutional review board approval for lower extremity amputations. Records of above and below knee amputation, Current Procedural Terminology codes 27590, 27591, 27592, 27594, 27596 and 27880, 27881, 27882, 27884, and 27886, respectively, from 1999 to 2018 were obtained. Incomplete and traumatic entries were removed. Risk sociated with higher rates of death and major cardiac (myocardial infarction, cardiac arrest), pulmonary (pneumonia, failure to wean vent, reintubation), and renal (renal insufficiency, renal failure) complications. We recommend the use of risk analysis index score as a frailty screening tool for patients undergoing lower extremity amputation to enable providers to adequately inform and counsel patients regarding potential significant risks.

In Canada, tissue distribution is managed by provincial entities. In 2014, Hema-Quebec established a cryopreserved vascular tissue bank accessible to all Canadian hospitals. The objectives of this report were to review the first 5years of activity of Hema-Quebec's vascular bank and to briefly assess the competitiveness of its products.

Deceased donors, ages 15 to 60, were screened for common blood-borne diseases. Grafts were treated in a triple-antibiotic solution at 35°C before preservation at -100°C. Hema-Quebec's vascular graft records were analyzed from 2014 to 2019 inclusively.

The average donor age was 35years old and 78% of donors were men. Overall, 63% of harvested grafts cleared the quality management system. Positive microbial cultures and morphologic defects were the major reasons for graft discard. As such, a total of 60 grafts were delivered between 2016 and 2019 to 8 hospital centers. Epigallocatechin in vitro Moreover, the bank achieved a mean activity increase of 55% per year and Hema-Quebec's homografts were 48% less costly compared with similar homographs from for-profit organizations.

Our findings demonstrate that Hema-Quebec has established a viable cryopreserved vascular tissue bank with steady increase in activity and an acceptable graft discard rates and pricing. Based on our findings, we recommend that efforts should be directed to expand the tissue bank graft distribution outside the province of Quebec.

The risk of aortic abdominal aneurysm (AAA) rupture increases with an increasing aneurysm diameter. However, the effect of the AAA diameter on late outcomes after aneurysm repair is unclear. Therefore, we assessed the association of a large AAA diameter with late outcomes for patients undergoing open and endovascular AAA repair.

We identified all patients who had undergone elective open or endovascular infrarenal aneurysm repair from 2003 to 2016 in the Vascular Quality Initiative linked to Medicare claims for long-term outcomes. A large AAA diameter was defined as a diameter >65mm. We assessed the 5-year reintervention, rupture, mortality, and follow-up rates. We constructed propensity scores and used inverse probability-weighted Kaplan-Meier estimations and Cox proportional hazard models to identify independent associations between large AAA repair and our outcomes.

Of the 21,119 aneurysm repairs identified, 15.2% were for large AAAs. Of the 21,119 repairs, 19,017 were endovascular and 2102 were open.
