ANNALS OF VASCULAR SURGERY. Immediate and Two-year Outcomes after EVAR in “On-label” and “Off-label” Neck Anatomies Using Different Commercially Available Devices. Analysis of the Experience of Two Italian Vascular Centers

Background: Endovascular aneurysm repair (EVAR) has fast become the therapeutic strategy of choice for abdominal aortic aneurysms (AAAs). Nowadays, the most important limit to the effectiveness of this technique is represented by complex anatomical situations, especially regarding the morphology of the proximal sealing zone. The aim of this study was to evaluate the 2-year outcome of unselected, real-world patients with “off-label” (off-L) proximal necks treated in 2 high-volume Italian vascular centers.

ANNALS OF VASCULAR SURGERY. Chronic Mesenteric Ischemia after Partial Coverage of the Celiac Artery during TEVAR, Case Report, and Review of the Literature

Micheal Ayad, Zachary J. Senders, Sean Ryan, Babak Abai, Paul DiMuzio, Dawn M. Salvatore

Background: Thoracic endovascular aortic repair (TEVAR) has emerged as a safe and effective alternative to open surgery for treatment of thoracic aortic aneurysms. It has recently been reported that stent-graft coverage of the celiac artery (CA) during TEVAR is associated with a low risk of acute mesenteric ischemia. However, the long-term effect of CA coverage on foregut perfusion is unknown. Here, we report the case of a patient who underwent TEVAR with partial coverage of the CA and subsequently developed symptoms of chronic mesenteric ischemia (CMI). She was successfully treated with CA stent placement.

ANNALS OF VASCULAR SURGERY. Combined Antegrade–Retrograde Intervention to Improve Chronic Total Occlusion Recanalization in High-risk Critical Limb Ischemia

When conventional antegrade attempts (antegrade approach) to cross chronic total occlusion (CTO) lesions in critical limb ischemia (CLI) fail, and if surgical revascularization is not possible, limb outcomes may be expected to be poor. In this high-risk cohort, we sought to examine whether combined antegrade–retrograde intervention with the simultaneous use of a distal retrograde access (combined approach) improves recanalization success.

AMERICAN JOURNAL OF ROENTGENOLOGY. Essentials of Endovascular Abdominal Aortic Aneurysm Repair Imaging: Postprocedure Surveillance and Complications

Andrew C. Picel and Nikhil Kansal

OBJECTIVE. Lifelong postprocedural imaging surveillance is necessary after endovascular abdominal aortic aneurysm repair (EVAR) to assess for complications of endograft placement, as well as device failure and continued aneurysm growth. Refinement of the surveillance CT technique and development of ultrasound and MRI protocols are important to limit radiation exposure.

CIRCULATION. Clinical Science. Predicting In-Hospital Mortality in Acute Type B Aortic Dissection

Jip L. Tolenaar, MD, PhD; Whit Froehlich; Frederik H.W. Jonker, MD, PhD; Gilbert R. Upchurch Jr, MD; Vincenzo Rampoldi, MD; Thomas T. Tsai, MD, MSc; Eduardo Bossone, MD, PhD; Arturo Evangelista, MD; Patrick O’Gara, MD; Linda Pape, MD; Dan Montgomery; Eric M. Isselbacher, MD; Christoph A. Nienaber, MD; Kim A. Eagle, MD; Santi Trimarchi, MD, PhD

Background: The outcome of patients with acute type B aortic dissection (ABAD) is strongly related to their clinical presentation. The purpose of this study was to investigate predictors for mortality among patients presenting with ABAD and to create a predictive model to estimate individual risk of in-hospital mortality using the International Registry of Acute Aortic Dissection (IRAD).

CIRCULATION. Cardiovascular Surgery. Improved Quality of Life After 1 Year With an Invasive Versus a Noninvasive Treatment Strategy in Claudicants

Joakim Nordanstig, MD, PhD; Charles Taft, MD, PhD; Marlene Hensäter, RN; Angelica Perlander, MD; Klas Österberg, MD, PhD; Lennart Jivegård, MD, PhD

Background: The quality of evidence for invasive revascularization in intermittent claudication is low or very low. This prospective, randomized, controlled study tested the hypothesis that an invasive treatment strategy versus continued noninvasive treatment improves health-related quality of life after 1 year in unselected patients with intermittent claudication.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Long-term Outcome of Endovascular Repair of Popliteal Artery Aneurysm Presents a Credible Alternative to Open Surgery

John H. Saunders, Said Abisi, Nishath Altaf, Yao Yong, Shane T. MacSweeney, Simon Whittaker, Said Habib

Purpose: Endovascular repair of popliteal artery aneurysms (PAA) has become increasingly popular; however, long-term patency and limb salvage rates are not fully established.

Purpose: In many patients with critical limb ischemia (CLI), transfemoral endovascular recanalization is the preferred treatment. Transpopliteal treatment may be used in patients with inaccessible groins. This retrospective study regards transpopliteal stenting of superficial femoral artery (SFA) occlusions using a 4F system.
