Sex and outcomes after stenting and endarterectomy in asymptomatic severe carotid stenosis patients.

Objectives: To determine if sex was an effect modifier in a pooled analysis of asymptomatic patients from CREST and ACT I.

Materials And Methods: We analyzed data from 2544 patients aged <80 with ≥70 % asymptomatic carotid stenosis randomized to CAS or CEA (n = 1091; n = 1453). The pre-specified primary endpoint in both trials was any stroke, myocardial infarction or death during the peri-procedural period, or ipsilateral stroke within 4 years of randomization.

Acute ischemia secondary to popliteal artery stent fracture and embolization.

Femoropopliteal disease comprises more than one half of lesions in peripheral vascular disease. The treatment modalities for stenosis or occlusion of this anatomic region include femoropopliteal bypass and percutaneous transluminal angioplasty with or without stenting. Our patient developed acute leg ischemia 3 years after stenting, secondary to stent fracture, with distal embolization of stent fragments.

Effect of Two Years of Doxycycline Treatment on Infrarenal Aortic Neck Diameter.

Objective: Endovascular aneurysm repair (EVAR) is a widely used option for patients with suitable vascular anatomy who have a large infrarenal abdominal aortic aneurysm (AAA). Neck diameter is the primary anatomical determinant of EVAR eligibility and device durability. Doxycycline has been proposed to stabilise the proximal neck after EVAR.

Surgeon Learning Curve and Clinical Outcomes of Minimally Invasive Anterior Lumbar Interbody Fusion With Posterior Percutaneous Instrumentation.

Objectives: This study reports the learning phase of the minimally invasive anterior lumbar interbody fusion (mini-ALIF) approach with a vascular and orthopaedic spine surgeon team.

Methods: Adult patients who underwent primary mini-ALIF at the lowest two segments of the lumbar spine (i.e.

Role of volume in small abdominal aortic aneurysm surveillance.

Objective: Current management of small abdominal aortic aneurysms (AAAs) primarily involves serial imaging surveillance of maximum transverse diameter (MTD) to estimate rupture risk. Other measurements, such as volume and tortuosity, are less well-studied and may help characterize and predict AAA progression. This study evaluated predictors of AAA volume growth and discusses the role of volume in clinical practice.

Post-kidney transplant serum magnesium exhibits a U-shaped association with subsequent mortality: an observational cohort study.

Hypomagnesemia is common in kidney transplant recipients (KTRs). We sought to explore the relationship between Mg and outcomes in KTRs, which may be associated with mortality and thus may be a potential intervention target to improve outcomes. We followed KTRs performed between 01/2000 and 6/2016 at a large US transplant center from 6 months post-transplant to graft failure, death, or loss to follow-up.

Anatomic eligibility for endovascular aneurysm repair preserved over 2 years of surveillance.

Objective: Endovascular aneurysm repair (EVAR) is a widely used option for patients with suitable vascular anatomy who have a large infrarenal abdominal aortic aneurysm (AAA). Patients with small AAAs are managed with careful surveillance and it is a common concern that their anatomy may change with AAA growth, and their option for EVAR may become limited. Device innovation has resulted in expanded ranges of anatomy that may be eligible for EVAR.

Evaluating Growth Patterns of Abdominal Aortic Aneurysm Diameter With Serial Computed Tomography Surveillance.

Importance: Small abdominal aortic aneurysms (AAAs) are common in the elderly population. Their growth rates and patterns, which drive clinical surveillance, are widely disputed.

Objective: To assess the growth patterns and rates of AAAs as documented on serial computed tomography (CT) scans.

CT-Derived Pretreatment Thoracic Sarcopenia Is Associated with Late Mortality after Thoracic Endovascular Aortic Repair.

Background: Frailty, characterized by physiologic depletion, predicts postoperative morbidity and mortality in vascular surgery patients. CT-derived sarcopenia is a valuable method for objectively staging frailty preoperatively.

Purpose: With prior analyses primarily measuring psoas cross-sectional area on CT, we compared a method of measuring thoracic sarcopenia to existing techniques of lumbar sarcopenia and assessed the association with long-term survival and outcomes post-Thoracic Endovascular Aortic Repair (TEVAR).

A Frailty-Based Risk Score Predicts Morbidity and Mortality After Elective Endovascular Repair of Descending Thoracic Aortic Aneurysms.

Background: Thoracic endovascular aortic repair (TEVAR) has expanded access to descending thoracic aortic aneurysm (DTAA) repair particularly for elderly and frail patients. This high-risk population has limited long-term overall survival, such that appropriate patient selection is required to optimize patient benefit and resource utilization. Our objective is to develop and validate a frailty-based, procedure-specific risk score for patients undergoing elective TEVAR for DTAA.

Derivation and validation of thoracic sarcopenia assessment in patients undergoing thoracic endovascular aortic repair.

Objective: Sarcopenia, as assessed by computed tomography (CT)-based measurements of muscle mass, is an objective and patient-specific indicator of frailty, which is an important predictor of operative morbidity and mortality. Studies to date have primarily focused on psoas-defined sarcopenia, which may not be valid among patients with thoracic aortic disease. Using psoas sarcopenia as the reference for sarcopenia, the purpose of this study was to create and to validate a new thoracic-level method of measuring sarcopenia as a novel method to assess frailty among patients undergoing thoracic endovascular aortic repair.
