Objective Gender-related differences in outcomes in complex endovascular aortic repair have not been profoundly investigated. Use of low profile abdominal devices as in chimney endovascular repair may be beneficial for female patients with pararenal pathologies. With the chimney technique, there is no need for large introduction sheaths. This could be an advantage in case of smaller in diameter iliac access especially in combination with stenosis or elongation. Aim of the present study was to compare the perioperative and mid-term outcomes between males and females patients treated with the chimney/snorkel technique for pararenal aortic pathologies...

Objectives Upper extremity arterial access is often required for endovascular procedures, especially for antegrade access to the visceral aortic branches. Radial arterial access has been shown previously to have low complication rates, and patients tolerate the procedure well and are able to recover quickly. However, transradial access remains relatively uncommon amongst vascular surgeons. Methods The radial artery was evaluated by ultrasound to evaluate for adequate caliber, and to identify any aberrant anatomy or arterial loops...

Aim The role of serum uric acid in ischemic stroke is controversial. On the one hand, it has a role as neuroprotectant in acute phase, but on the other hand, it may promote atherosclerosis in carotid arteries. Our aim is to investigate the association of serum uric acid levels at admission of acute ischemic stroke patients with carotid disease. Methods Cross-sectional study of patients admitted due to acute ischemic stroke. Clinical and laboratory variables were recorded. The carotid disease was defined based on the findings of carotid echography intima to media thickness and stenosis...

Objective Custom-made fenestrated aortic endografts allow exclusion of pararenal aortic aneurysms while maintaining blood flow to aortic branches. Meticulous device planning and precise deployment of the main body are essential to allow successful cannulation of the fenestrations. This study investigates whether a learning curve can be observed with more reliable cannulation and connection of fenestrations over time at a single department of vascular and endovascular surgery with multiple surgeons trained to use the device...

Objectives Previously, we found that urinary fibrinogen (Fg) levels were positively related to contrast-induced acute renal injury degree in mice. Reduction of fibrinogen in heterozygous mice can improve renal function. Here, we prospectively observed the variation in urinary Fg levels in patients undergoing angiography to determine the relationship between serum creatinine (Scr) and serum cystatin C (Cys C) levels. Methods Serum Cys C and urinary Fg levels were evaluated by ELISA before and 2, 12, and 24 h after angiography in 115 enrolled inpatients...

Objective Patients with critical limb ischemia have serious systemic comorbidities and are at high risk of impairment of limb function. In this study, we assessed the prognostic factors of limbs after revascularization. Methods In this retrospective single-center cohort study, from April 2008 to December 2012, we treated 154 limbs of 121 patients with critical limb ischemia by the endovascular therapy-first approach based on the patients' characteristics. The primary end point was amputation-free survival. Secondary end points were patency of a revascularized artery, major adverse limb events, or death...

Objective Acute limb ischemia is a common vascular emergency requiring immediate intervention. Thrombolysis has been widely utilized for acute limb ischemia; the purpose of this study is to analyze contemporary trends, outcomes and complications of thrombolysis for acute limb ischemia. Methods Patients were identified from the Nationwide Inpatient Sample (2003-2013) using ICD-9. Patients undergoing emergency thrombolysis for acute limb ischemia were evaluated. Three groups were analyzed: thrombolysis alone, thrombolysis and endovascular procedure (T+ENDO), and failed thrombolysis requiring open surgery (T+OPEN)...

Objectives To investigate the initial outcomes of 1940 nm diode laser in the treatment of incompetent saphenous veins. Methods This was a prospective observational study. We treated 89 patients with 160 incompetent saphenous veins using a 1940 nm diode laser and bare fiber. The laser's power was set to 4.5 W with a mean linear endovenous energy density of 50.4 J/cm. Results The one-month closure rate was 100%. The post-procedural pain score at 6 h, 1 day, 10 days, and 1 month was 0.85 ± 1.04, 0.65 ± 1...

Objective Carotid stenosis with crescendo-transient-ischemic-attack (cTIA) requires a prompt intervention to reduce the stroke risk. Few data are reported in literature about cTIA suggesting a different perioperative risk compared with patients with single TIA (sTIA). This study aimed to compare the outcome of carotid endarterectomy (CEA) in patients with TIA (single/crescendo) and evaluate the outcome risk-factors. Methods Data from two tertiary hospitals for vascular treatment were analyzed from 2007 to 2016...

Demographic data, procedural properties, and follow-up information were recorded. The technical, procedural and clinical successes were reported. Results In total, 120 subjects were evaluated. The superficial femoral artery (SFA) group consisted of 64 subjects (53...

Objectives Choosing an optimal amputation level requires balance between maximizing limb salvage while minimizing chances of non-healing wounds and re-amputation. Our aim was to assess the long-term outcome for minor amputations in patients with peripheral vascular disease. Methods A retrospective study of minor amputations between January 1, 2005 and December 31, 2015 was performed. Electronic medical records of eligible patients were examined to extract demographics, co morbidities and clinical data. Results Within the study period, 220 patients underwent 296 primary minor amputations in 244 lower extremities...

Background This paper describes and analyzes the cellular and molecular mechanisms underlying atherosclerosis development. In particular, the roles of monocytes/macrophages, smooth muscle cells, and vascular endothelium in the formation of stable/unstable atheromatous plaques, and the contributions of some processes to atheroma formation. Methods and results In this study we analyzed endothelium: function, dysfunction, and involvement into atherogenesis; cell proteins mediating mechanotransduction; proatherogenic role of monocytes; the role of macrophages in the development of unstable atheromatous plaques and smooth muscle cell origin in atherosclerosis...

Objectives Peripheral arterial disease most commonly presents as intermittent claudication (IC). Early evidence has suggested that extracorporeal shockwave therapy is efficacious in the short term for the management of intermittent claudication. The objective of this pilot trial was to evaluate the medium-term efficacy of this treatment. Methods This double-blind randomised placebo-controlled pilot trial randomised patients with unilateral intermittent claudication in a 1:1 fashion to receive extracorporeal shockwave therapy or a sham treatment for three sessions per week over three weeks...

Background The endovascular approach became an alternative to open surgical treatment of popliteal artery aneurysm over the last few years. Heparin-bonded stent-grafts have been employed for endovascular popliteal artery aneurysm repair, showing good and stable results. Only few reports about the use of multilayer flow modulator are available in literature, providing small patient series and short follow-up. The aim of this study is to report the outcomes of patients with popliteal artery aneurysm treated with the multilayer flow modulator in three Italian centres...
