Dynamic Computed Tomography Angiography as Imaging Method for Endoleak Classification after Endovascular Aneurysm Repair: A Case Series and Systematic Review of the Literature.

Introduction: This study evaluated our experience with dynamic computed tomography angiography (dCTA) as a diagnostic tool after endovascular aortic aneurysm repair (EVAR) with respect to the endoleak classification and the available literature.

Methods: We reviewed all patients who underwent dCTA because of suspected endoleaks after the EVAR and classified the endoleaks in these patients based on standard CTA (sCTA) and dCTA. We systematically reviewed all available publications that investigated the diagnostic accuracy of dCTA compared with other imaging techniques.

A stable aneurysm sac after endovascular aneurysm repair as a predictor for mortality: An in-depth analysis.

Objective: The aim of the present study was to compare the long-term survival of patients with a stable aneurysm sac vs those with aneurysm sac regression after endovascular aneurysm repair (EVAR) and to identify the independent risk factors for aneurysm sac regression and mortality after EVAR.

Methods: We reviewed all the patients who had undergone EVAR from 2005 to 2018 with computed tomography angiography available at 1 year of follow-up. Aneurysm sac regression was defined as a diameter decrease of >10%.

Acute severe abdominal pain in a young woman caused by a well-differentiated papillary mesothelioma of the peritoneum.

Acute abdominal pain is a common symptom in young women. We describe a patient with acute illness and severe lower abdominal pain. Laboratory tests were normal except for mildly deranged inflammatory markers.

Risk of abdominal aortic aneurysm (AAA) among male and female relatives of AAA patients.

Sex affects the presentation, treatment, and outcomes of abdominal aortic aneurysm (AAA). Although AAAs are less prevalent in women, at least in the general population, women with an AAA have a poorer prognosis in comparison to men. Sex differences in the genetic predisposition for aneurysm disease remain to be established.

First genetic analysis of aneurysm genes in familial and sporadic abdominal aortic aneurysm.

Genetic causes for abdominal aortic aneurysm (AAA) have not been identified and the role of genes associated with familial thoracic aneurysms in AAA has not been explored. We analyzed nine genes associated with familial thoracic aortic aneurysms, the vascular Ehlers-Danlos gene COL3A1 and the MTHFR p.Ala222Val variant in 155 AAA patients.

The impact of perioperative red blood cell transfusions on postoperative outcomes in vascular surgery patients.

Background: Red blood cell (RBC) transfusions are common in vascular surgery and aim to reduce tissue ischemia. However, the evidence that transfusions are beneficial is contradictory. This study evaluates the impact of perioperative transfusion (transfusion within 3 days of surgery) on 30-day postoperative outcomes in elective vascular surgery patients.

Extracellular matrix defects in aneurysmal Fibulin-4 mice predispose to lung emphysema.

Background: In this study we set out to investigate the clinically observed relationship between chronic obstructive pulmonary disease (COPD) and aortic aneurysms. We tested the hypothesis that an inherited deficiency of connective tissue might play a role in the combined development of pulmonary emphysema and vascular disease.

Methods: We first determined the prevalence of chronic obstructive pulmonary disease in a clinical cohort of aortic aneurysms patients and arterial occlusive disease patients.

Lower atherosclerotic burden in familial abdominal aortic aneurysm.

Objective: Despite the apparent familial tendency toward abdominal aortic aneurysm (AAA) formation, the genetic causes and underlying molecular mechanisms are still undefined. In this study, we investigated the association between familial AAA (fAAA) and atherosclerosis.

Methods: Data were collected from a prospective database including AAA patients between 2004 and 2012 in the Erasmus University Medical Center, Rotterdam, The Netherlands.

Familial abdominal aortic aneurysm is associated with more complications after endovascular aneurysm repair.

Objective: A familial predisposition to abdominal aortic aneurysms (AAAs) is present in approximately one-fifth of patients. Nevertheless, the clinical implications of a positive family history are not known. We investigated the risk of aneurysm-related complications after endovascular aneurysm repair (EVAR) for patients with and without a positive family history of AAA.

Impact of haemoglobin concentration on cardiovascular outcome after vascular surgery: a retrospective observational cohort study.

Background: Although low preoperative haemoglobin (Hb) concentration is a well known risk factor for adverse outcome, little is known about decreases in Hb and postoperative Hb concentrations.

Objectives: The aim of this study was to evaluate the prognostic impact of both pre- and postoperative Hb concentrations (divided into low, intermediate and high tertiles) as well as Hb decrease, defined as preoperative minus postoperative Hb (g dl(-1)), on postoperative cardiovascular events in vascular surgery patients.

Design: A retrospective observational cohort study.

Conservative management of persistent aortocaval fistula after endovascular aortic repair.

Endovascular repair is a valid alternative for patients with abdominal aortic aneurysms. However, in patients with concomitant aortocaval fistulas, type II endoleaks may result in a persistent communication between the aneurysm sac and the inferior vena cava. In these patients, prompt closure of the persistent fistula has been advocated.

Adequate seal and no endoleak on the first postoperative computed tomography angiography as criteria for no additional imaging up to 5 years after endovascular aneurysm repair.

Objective: Intensive image surveillance after endovascular aneurysm repair is generally recommended due to continued risk of complications. However, patients at lower risk may not benefit from this strategy. We evaluated the predictive value of the first postoperative computed tomography angiography (CTA) characteristics for aneurysm-related adverse events as a means of patient selection for risk-adapted surveillance.

Aneurysmal disease is associated with lower carotid intima-media thickness than occlusive arterial disease.

Objective: Patients with aneurysmal and occlusive arterial disease have overlapping cardiovascular risk profiles. The question remains how atherosclerosis is related to the formation of aortic aneurysms. Common carotid artery intima-media thickness (CIMT) is an easily accessible and objective marker of early atherosclerosis.

Stent graft composition plays a material role in the postimplantation syndrome.

Objective: In patients undergoing endovascular aneurysm repair (EVAR), the postimplantation syndrome (PIS), comprising fever and inflammation, occurs frequently. The cause of PIS is unclear, but graft composition and acute thrombus formation may play a role. The objective of this study was to evaluate these possible causes of the inflammatory response after EVAR.

Supervised walking therapy in patients with intermittent claudication.

Objective: Exercise therapy is a common intervention for the management of intermittent claudication (IC). However, considerable uncertainty remains about the effect of different exercise components such as intensity, duration, or content of the exercise programs. The aim of this study was to assess the effectiveness of supervised walking therapy (SWT) as treatment in patients with IC and to update and identify the most important exercise components resulting in an optimal training protocol for patients with IC.

Influence of aortic valve calcium on outcome in patients undergoing peripheral vascular surgery.

Vascular surgery patients are at increased risk of adverse cardiovascular events because of silent coronary artery disease and an increased propensity for left ventricular dysfunction. The Revised Cardiac Risk Index is commonly used for preoperative risk stratification. Aortic valve calcium is associated with cardiovascular mortality in the general population.

Open elbow contracture release: postoperative management with and without continuous passive motion.

Purpose: Surgical contracture release can restore motion to stiff elbows. Some authors suggest that use of continuous passive motion (CPM) in postoperative management can increase ultimate mobility. This study tests the null hypothesis that there is no difference in the arc of flexion and extension between patients who used CPM and those who did not use CPM after open elbow contracture release.
