Differential Expression Analyses on Human Aortic Tissue Reveal Novel Genes and Pathways Associated With Abdominal Aortic Aneurysm Onset and Progression.

Background: Abdominal aortic aneurysms (AAAs) are focal dilatations of the abdominal aorta that expand progressively, increasing their risk of rupture. Rupture of an AAA is associated with high mortality rates, but the mechanisms underlying the initiation, expansion, and rupture of AAAs are not yet fully understood. We aimed to characterize the pathophysiology of AAAs and identify new genes associated with AAA initiation and progression.

Type Ib endoleak repaired with a thoracic endovascular graft inside previous visceral debranching bypass in a patient with chronic type B aortic dissection.

We present the case of a patient with chronic type B aortic dissection with a previous iliac to visceral debranching graft and thoracoabdominal endograft who, because of a type Ib endoleak and aortic diameter enlargement, required a complex solution involving placement of a thoracic endovascular graft inside a Dacron graft with a 180° curved shape in three-stage surgery. At 9 months of follow-up, he had no evidence of type I endoleaks, and the aortic diameter had decreased.

Preoperative geriatric assessment, a promising tool to improve outcomes in aortic pathology interventions.

Background: Due to population aging and the spread of endovascular techniques for aortic diseases, there has been an increase in older population intervened. Objectively assessing patient's global status becomes mandatory in advanced ages, as impaired functional status and frailty are associated with higher postoperative mortality rates. The aim of this paper is to evaluate the impact of a systematic geriatric preoperative assessment on the outcomes of aortic interventions.

Finite element analysis in symptomatic and asymptomatic abdominal aortic aneurysms for aortic disease risk stratification.

Background: Advanced biomechanical models can provide additional information concerning rupture risk in abdominal aortic aneurysms (AAA). Here we evaluated the predictive value of finite element analysis (FEA) to assess AAA rupture risk.

Methods: In a case-control study, we compared FEA parameters in a group of symptomatic AAA (sAAA) patients, considered as a high risk of rupture group, with FEA parameters in asymptomatic AAA patients (aAAA).

Endovascular Management of Ureteroarterial Fistula: Single Institution Experience and Systematic Literature Review.

Background: Ureteroarterial fistula (UAF) represents an uncommon complication after urological surgery; however, this is a well-documented condition in patients with predisposing risk factors. The aim of the present study is to report and analyze the endovascular management of a series of patients with UAF, treated in authors' hospital, and to report and analyze the same data concerning patients retrieved from a systematic literature review.

Methods: Authors conducted a retrospective analysis of prospectively collected data and a systematic literature review.

Induction of histone deacetylases (HDACs) in human abdominal aortic aneurysm: therapeutic potential of HDAC inhibitors.

Clinical management of abdominal aortic aneurysm (AAA) is currently limited to elective surgical repair because an effective pharmacotherapy is still awaited. Inhibition of histone deacetylase (HDAC) activity could be a promising therapeutic option in cardiovascular diseases. We aimed to characterise HDAC expression in human AAA and to evaluate the therapeutic potential of class I and IIa HDAC inhibitors in the AAA model of angiotensin II (Ang II)-infused apolipoprotein-E-deficient (ApoE(-/-)) mice.

CHIVA method for the treatment of chronic venous insufficiency.

Background: Many surgical approaches are available to treat varicose veins secondary to chronic venous insufficiency. One of the least invasive techniques is the ambulatory conservative hemodynamic correction of venous insufficiency method (cure conservatrice et hémodynamique de l'insuffisance veineuse en ambulatoire (CHIVA)), an approach based on venous hemodynamics with deliberate preservation of the superficial venous system. This is an update of the review first published in 2013.

Microvascular COX-2/mPGES-1/EP-4 axis in human abdominal aortic aneurysm.

We investigated the prostaglandin (PG)E2 pathway in human abdominal aortic aneurysm (AAA) and its relationship with hypervascularization. We analyzed samples from patients undergoing AAA repair in comparison with those from healthy multiorgan donors. Patients were stratified according to maximum aortic diameter: low diameter (LD) (<55 mm), moderate diameter (MD) (55-69.

CHIVA method for the treatment of chronic venous insufficiency.

Background: Many surgical approaches are available to treat varicose veins secondary to chronic venous insufficiency. One of the least invasive techniques is the ambulatory conservative hemodynamic correction of venous insufficiency method (cure conservatrice et hémodynamique de l'insuffisance veineuse en ambulatoire (CHIVA)), an approach based on venous hemodynamics with deliberate preservation of the superficial venous system.

Objectives: To compare the efficacy and safety of the CHIVA method with alternative therapeutic techniques to treat varicose veins.

Compression assisted by removable coils as a new treatment for iatrogenic femoral pseudoaneurysms.

To avoid undesirable effects that sometimes result from current treatments for postpuncture femoral pseudoaneurysms, we developed a new technique involving compression assisted by removable coils. Using ultrasound-guided percutaneous puncture, an Inconel coil with synthetic microfibers is inserted in the pseudoaneurysm, leaving a part of the coil above the skin. Short-duration, ultrasound-guided compression is applied, taking advantage of the coil's thrombogenicity.
