Objective: The objective of this study was to analyze the early and late outcomes of patients who require a suprarenal aortic cross-clamp during elective open repair of an abdominal aortic aneurysm (AAA).
Objective: The objective of this study was to evaluate the anatomic feasibility of two off-the-shelf fenestrated stent graft designs to treat juxtarenal and pararenal abdominal aortic aneurysms (AAAs).
Objective: Recent approval by the Food and Drug Administration of custom fenestrated endografts has increased endovascular options for patients with short-neck or juxtarenal abdominal aortic aneurysms (AAAs). We sought to compare the early learning curve at a single institution of fenestrated repair vs the snorkel technique.
Objective_ The benefit of fenestrated endovascular aortic aneurysm repair (FEVAR) compared with open surgical repair (OSR) of complex abdominal aortic aneurysms (CAAAs) is unknown. This study compares 30-day outcomes of these procedures from two high-volume centers where FEVAR was undertaken for high-risk patients.
Objective: “Chimney” techniques used to extend landing zones for endovascular aortic repair (chEVAR) have been increasingly reported; however, concerns about durability and patency remain. The purpose of this analysis was to examine midterm outcomes of chEVAR.
Objective: Despite improvements in endograft technology, operator skill, and patient selection, endovascular aneurysm repair continues to be associated with device-related complications. A retrospective, observational study was undertaken to evaluate the clinical outcome and imaging findings of a unique device having externally-mounted, conformable graft material.
Objective: Proximal attachment site complications continue to occur after endovascular repair of abdominal aortic aneurysms (EVAR), specifically type Ia endoleak and endograft migration. EndoAnchors (Aptus Endosystems, Sunnyvale, Calif) were designed to enhance endograft proximal fixation and sealing, and the current study was undertaken to evaluate the potential benefit of this treatment.
Background: Radiation-induced skin injury is a serious potential complication of fluoroscopically guided interventions. Transient erythema occurs at doses of 2 to 5 Gy, whereas permanent epilation, ulceration, and desquamation are expected at doses above this level. Complex endovascular procedures (CEPs), such as fenestrated endovascular aortic aneurysm repair (FEVAR), are associated with high radiation doses, yet the prevalence of radiation-induced skin injury is unknown. We hypothesized that skin injury after these exposures is likely to be underrecognized and underreported. This study examined the frequency and severity of deterministic effects and evaluated patient characteristics that might predispose to radiation injury in CEP.
Background: High-sensitivity C-reactive protein (hsCRP) and brain natriuretic peptide (BNP) have been shown to be independent predictors of adverse cardiovascular outcomes and increased risk of secondary interventions or limb loss in patients with peripheral arterial disease (PAD). To assist clinicians in decision-making about treatment approaches and predicting postprocedure mortality and morbidity, we retrospectively examined patients with preprocedure hsCRP and BNP levels who underwent elective angioplasty or stent placement for lower extremity PAD.
Background: Endovascular intervention has become a frequently used treatment of critical limb ischemia (CLI) in recent times. The recent Bypass vs Angioplasty in Severe Ischaemia of the Leg (BASIL) trial consensus recommended endovascular treatment as a first-line treatment in patients who have a life expectancy that was limited to <2 years. Despite these recommendations, there still remains limited data available to clinicians when seeking to risk stratify patients who present with CLI. The neutrophil-lymphocyte ratio (NLR) has been suggested to be a marker for predicting mortality and patency. This study aimed to investigate the use of the NLR as a prognostic marker for primary patency and mortality after an infrapopliteal endovascular intervention in patients with CLI.
Objective: The durability of an infrainguinal bypass may be hampered by development of stenosis at the anastomoses. We describe the patency of percutaneous transluminal angioplasty (PTA) of these anastomotic stenoses.
Objective: Acute mesenteric ischemia (AMI) encompasses the sequels of end-stage untreated chronic mesenteric ischemia and acute mesenteric artery thrombosis. Percutaneous mesenteric artery stenting (PMAS) is the preferred treatment of patients with AMI but is not always feasible. Retrograde open mesenteric stenting (ROMS) is a hybrid technique that combines the advantages of open surgical and endovascular approaches. The literature on the results of this new technique is scarce. The aim of this study was to evaluate the results of ROMS in a consecutive series of patients with AMI.
Objective: Patients receiving interfacility transfer to a higher level of medical care for ruptured abdominal aortic aneurysms (rAAAs) are an important minority that are not well characterized and are typically omitted from outcomes and quality indicator studies. Our objective was to compare patients transferred for treatment of rAAAs with those treated without transfer, with particular emphasis on mortality and resource utilization.
Objective: The snorkel approach for endovascular aneurysm repair (EVAR) has been found to be a safe and viable alternative to open repair for juxtarenal abdominal aortic aneurysms with good short-term outcomes. Concerns about long-term durability and renal branch patency with this technique have been raised with the increasing availability of fenestrated devices. We sought to evaluate renal function changes in patients undergoing “snorkel” EVAR (sn-EVAR).
Objective: We have previously shown that duplex ultrasonography (DU) may replace computed tomography angiography (CTA) as the primary surveillance tool for endovascular aortic aneurysm repair (EVAR). Current Society for Vascular Surgery practice guidelines suggest that if CTA does not document endoleak, aneurysm sac enlargement, or limb stenosis by 12 months after EVAR, surveillance studies may be performed annually. The purpose of this study was to determine whether the time to the second surveillance DU study can be safely postponed to 3 years after EVAR if the initial study finding is normal.
