The Society for Vascular Surgery's Annual Meeting acts as a means of disseminating research findings among vascular surgeons through the presentation of research abstracts. Following presentation at the meeting, research is often compiled into a full-text manuscript and submitted to a peer-reviewed journal. However, not all abstracts accepted to the Vascular Annual Meeting (VAM) eventually have a corresponding full-text publication. The objectives of this study were to establish the publication rate of abstracts presented between 2012 and 2015 to the VAM and to identify factors correlating with publication status. ⋯ From 2012 to 2015, 43.0% of VAM abstracts had a corresponding full-text publication, with greater sample size and a positive status of outcome positively correlating with likelihood of publication. Studies with negative findings made up a small proportion of conference abstracts (9.6%) and were the least likely to be published. Given the relatively small size of the specialty of vascular surgery, it may be particularly important to be mindful of publication bias. It may be worthwhile to give additional consideration to acceptance of abstracts or publication of studies with negative results that meaningfully contribute to the literature.

Case Reports Clinical Trial
Long-term durability of multibranched endovascular repair of thoracoabdominal and pararenal aortic aneurysms.
The objective of this study was to assess the durability of multibranched endovascular repair of thoracoabdominal aortic aneurysms (TAAAs) and pararenal aortic aneurysms by examining the rates of late-occurring (beyond 30 days) complications. ⋯ Total endovascular repair of TAAAs and pararenal aortic aneurysms using axially oriented cuffs is safe, effective, and durable in the long term.

Multicenter Study Clinical Trial
Outcomes of the GORE Iliac Branch Endoprosthesis in clinical trial and real-world registry settings.
We report midterm outcomes with the GORE Iliac Branch Endoprosthesis (IBE; W. L. Gore & Associates, Flagstaff, Ariz) in the U.S. investigational device exemption (IDE) trial and comparatively assess outcomes in the IDE trial with outcomes in a real-world population of patients treated in the Gore Global Registry for Endovascular Aortic Treatment (GREAT). ⋯ Midterm IDE outcomes and 6-month outcomes in the worldwide GREAT registry suggest that endovascular aortic aneurysm repair with concomitant CIA aneurysm repair with the IBE device is safe and effective. Thrombotic events are uncommon and are concentrated in the first month after the index procedure, and they typically can be resolved with endovascular reintervention.

The external carotid artery (ECA) is inadvertently occluded during carotid endarterectomy (CEA). The importance of ECA occlusion has been emphasized as a loss of extracranial to intracranial collaterals, a source of chronic embolization, or a site for extended thrombosis during wound closure. This study aimed to determine whether ECA occlusion that inadvertently developed during endarterectomy and that was eventually detected using blood flow measurement of the ECA after declamping of all carotid arteries is a risk factor for development of new postoperative ischemic lesions at declamping of the ECA and common carotid artery (CCA) while clamping the internal carotid artery (ICA). This study also aimed to determine whether intraoperative transcranial Doppler (TCD) monitoring predicts the risk for development of such lesions. ⋯ ECA occlusion at declamping of the ECA and CCA while clamping the ICA during CEA is a risk factor for development of new postoperative ischemic lesions. Intraoperative TCD monitoring accurately predicts the risk for development of such lesions.

Although endovascular repair of abdominal aortic aneurysms (AAAs) has been demonstrated to have favorable outcomes, not all cohorts of patients with AAA fare equally well. Our goal was to investigate perioperative and 1-year outcomes in patients with end-stage renal disease (ESRD) on dialysis, who have traditionally fared worse after vascular interventions, to assess how ESRD affects outcomes in a large modern cohort of endovascular aneurysm repair (EVAR) patients. ⋯ Among patients undergoing EVAR, ESRD is independently associated with higher perioperative and 1-year mortality despite not being associated with higher postoperative complications. This should be taken into account during informed consent for EVAR and risk-benefit considerations in this high-risk population, particularly for elective repair.
