Acute limb ischemia in nonagenarians: Characteristics and factors related to outcomes in a single-center consecutive series.

Background: The increasing aging and frailty of the population make the management of acute limb ischemia (ALI) more difficult, with decision-making far from being guided by evidence. The aim of the study was to evaluate the characteristics and results of ALI treatment in nonagenarians.

Materials And Methods: Retrospective analysis of a consecutive series of nonagenarian patients with ALI attended at our institution between 2008 and 2021.

Clinical characteristics and preoperative ultrasound parameters related to low patency in radio-cephalic arteriovenous fistulas.

Introduction: Our objective is to describe the clinical characteristics and preoperative ultrasound mapping parameters associated with primary and secondary patency of radio-cephalic arteriovenous fistulas (RCF).

Methods: A retrospective, single-center, descriptive study, including patients undergoing a RCF creation between 2015 and 2019. Socio-demographic data and ultrasound parameters were collected and an analysis of primary and secondary patency was performed.

Association of polypharmacy scores with the long-term survival of patients with intact aortoiliac aneurysms and indication for repair.

Objective/background: Our study analyzed the relationship between two polypharmacy scores (addition of chronic prescribed drugs [ACPDs] and Rx-Risk Comorbidity Index) and survival in patients with an intact abdominal aortic and/or common iliac aneurysm (AAA).

Methods: Consecutive retrospective, single-center cohort of patients attended for an intact AAA with indication for repair from 2008 to 2021. Demographic data, Charlson Comorbidity Index, AAA treatment, ACPD, and Rx-Risk polypharmacy scores were recorded at baseline.

Comparative performance of three comorbidity scores in predicting survival after the elective repair of abdominal aortic aneurysms.

Background: We aimed to study the discriminative power of 3 comorbidity scores for predicting 5-year survival after the elective repair of aorto-iliac aneurysms (AAA).

Methods: 444 patients with AAA undergoing elective repair (33% open and 67% endovascular) between 2000 and 2020 were reviewed. The Charlson Comorbidity Index (CCI) and subsequent adjustments by Schneeweiss, Quan and Armitage, the Modified Frailty Index (MFI) and the American Society of Anesthesiologists Score (ASA) were calculated from preoperative data.

Influence of Operative Time in the Results of Elective Endovascular Repair of Abdominal Aortic Aneurysms.

Background: A prolonged operative time (OT) is a well-recognized risk factor of postoperative complications after many open surgical procedures, although little is known about its impact in less-invasive endovascular procedures. We aimed to define the characteristics related to a prolonged OT in the endovascular treatment of aorto-iliac aneurysms (EVAR) and to evaluate the influence of OT on postoperative outcomes.

Methods: Retrospective analysis of 284 consecutive patients (mean age 75 years, 95% male) who underwent an elective EVAR between 2000 and 2019.

A cost-effectiveness analysis of the introduction of a specialised consultation with duplex ultrasound assessment prior to vascular access surgery for haemodialysis.

Introduction: Duplex ultrasound (DUS) is increasingly used before vascular access (VA) surgery for haemodialysis. However, the cost-effectiveness of this approach is unknown. Our objective was to assess whether the introduction of a specialised consultation with DUS assessment modifies the cost and the time delay to achieve a first VA valid for haemodialysis.

Critical Limb Ischemia in Nonagenarians: A Challenge of Our Times.

Background: As a result of the increasing life expectancy of the western population, the number of older patients with chronic limb-threatening ischemia (CLTI) seeking medical care is growing. Our objective was to describe the characteristics of a consecutive series of nonagenarian patients with CLTI and evaluate the outcomes of their management.

Materials And Methods: Retrospective analysis of a consecutive series of nonagenarian patients with CLTI attended at our institution between 2005 and 2019.

Kidney transplantation reduces the risk of chronic limb threatening ischemia and amputation among patients with end-stage renal disease on hemodialysis.

Objective: This study aimed to analyze the risk of chronic limb threatening ischemia (CLTI) or amputation among patients with end-stage renal disease (ESRD) entering a hemodialysis (HD) program and to evaluate the protective effect associated with kidney transplantation (KT).

Design, Material And Methods: Retrospective cohort of all consecutive ESRD patients entering into a HD program at our institution between 2000 and 2010. Collected variables included baseline characteristics (pre-entry in hemodialysis), time on HD program, KT and the composite outcome of chronic limb threatening ischemia or need for any amputation (CLTI/AMP).

Are continued policies of prioritizing native vascular access in patients on hemodialysis programs useful?

The guidelines recommend establishing native vascular access as opposed to prosthetic or catheter-based access despite information relating to its effectiveness being scarce from a patient-orientated perspective. We analyzed the effectiveness of a continued policy of native vascular access (CPNVA) in patients undergoing hemodialysis. A retrospective, observational study, including 150 patients undergoing hemodialysis between 2006 and 2012 at our center, and who underwent a CPNVA.

A cost-effectiveness analysis of the introduction of a specialised consultation with duplex ultrasound assessment prior to vascular access surgery for haemodialysis.

Introduction: Duplex ultrasound (DUS) is increasingly used before vascular access (VA) surgery for haemodialysis. However, the cost-effectiveness of this approach is unknown. Our objective was to assess whether the introduction of a specialised consultation with DUS assessment modifies the cost and the time delay to achieve a first VA valid for haemodialysis.

Outcome of elective endovascular repair of abdominal aortic aneurysms in octogenarians.

Aim: The need to adjust the indications of elective abdominal aortic aneurysm (AAA) repair among patients with a limited life-span deserves a specific evaluation for octogenarians. The aim of this study was to compare the postoperative results and the long-term survival after endovascular repair of abdominal aortic and/or iliac aneurysms (EVAR) in octogenarians compared with patients under 80 years of age.

Methods: Retrospective analysis of 241 consecutive patients who underwent an elective EVAR between 2000 and 2017.

Natural History After Below-knee Amputation: Analysis of Survival and Prosthetic Fitting Over 2 Decades.

Introduction: This study sought to evaluate the natural history of patients undergoing below-knee amputation (BKA) and compare their evolution over 2 decades, as well as survival predictors, prosthetic fitting, and contralateral amputation.

Methods: Retrospective study of 209 consecutive patients (mean age 72.9 years; 68% males) who underwent BKA in 2 periods: 1996-2005 and 2006-2015.

Renal denervation for the treatment of resistant hypertension in Spain. The Flex-Spyral Registry.

Introduction And Objectives: Renal denervation is a percutaneous intervention for the treatment of resistant hypertension. Randomized studies have shown contradictory results on its efficacy. We present the results of a renal denervation registry for the treatment of resistant hypertension in real-life patients in Spain.

Utility of doppler ultrasound in the preoperative evaluation of the first vascular access for haemodialysis.

Introduction: Traditionally, the indication of the type of vascular access (VA) has been based on the surgeon's physical examination, but it is now suggested that imaging methods could provide a clinical benefit. Our aim was to determine whether or not preoperative Doppler ultrasound modifies outcomes of the first VA for haemodialysis.

Patients And Methods: Prospective cohort of patients undergoing a first VA from June 2014 to July 2017 who had a preoperative Doppler ultrasound (ECO group).

[Aorto-bifermoral grafs infection due to Candida parapsilosis. An unusual pathogen].

Background: Aorto-enteric fistula is a rare and potentially lethal entity. Its presentation may be as an enteric-paraprosthetic fistula, due to injury in the gut caused by direct contact with the vascular prosthesis.

Objective: We report a case of enteric-paraprosthetic fistulae with the unusual finding of Candida parapsilosis as the only isolated pathogen.

Predictors of medium-term patency in percutaneous endovascular therapy of femoro-popliteal lesions.

Background: The objective is to study the medium-term results of angioplasty and stenting in the femoro-popliteal sector in patients with critical limb ischemia (CLI), and identify angiographic predictive factors of primary patency.

Patients And Methods: Retrospective review of 98 patients with critical ischemia and angiographic lesions characterized as TASC A=13 (14%), B=38 (40%), C=24 (25%) or D=20 (21%). A total of 106 angioplasties and primary self-expanding stents (mean length of stent coverage of 19cm) were performed between January 2006 and January 2011.
