Oncovascular Surgery for Soft-Tissue Sarcomas of the Lower Limbs with Vascular Contact: Comparison of Arterial Reconstruction and Arterial Subadventitial Dissection.

Background: Soft-tissue sarcomas represent approximately 1% of adult malignancies. When they involve the lower limbs (LLs) and come into contact with blood vessels, the therapeutic choice was historically a primary amputation. Today, radical surgical resection with wide margins of safety is the primary therapeutic option for multidisciplinary limb-salvage surgery.

Mortality and Delays of Management of Acute Mesenteric Ischemia: The Need of a Dedicated Program.

Background: To study the mortality and delays of management of patients with acute mesenteric ischemia (AMI) admitted to the emergency department of a tertiary hospital and identify risk factors for 1-month mortality.

Methods: A single-center and retrospective study including all consecutive patients treated for AMI from January 2008 to December 2018 was conducted. Short- and medium-term survival was studied with a Kaplan-Meier analysis.

Vascular grafts collagen coating resorption and healing process in humans.

Background: The objective of the present study was to evaluate the bioresorption rate of collagen coating (CC) sealed on textile vascular grafts (VGs) and their healing in humans using histologic analysis of explanted VGs.

Methods: A total of 27 polyester textile VGs had been removed during surgery from 2012 to 2020. The segments underwent histologic assessment.

Arterial Embolization of Polycystic Kidneys for Heterotopic Transplantation.

Introduction: The purpose of this study was to evaluate the efficacy of polycystic kidney embolization, performed to reduce kidney volume before heterotopic kidney transplantation, as this technique could be an alternative to pretransplant nephrectomy.

Materials And Methods: All patients who underwent pretransplant embolization of polycystic kidneys were included in a prospective register from June 2014 to February 2020. All patients underwent computed tomography (CT) scan with volumetric reconstruction (OsiriX, Bernex, Switzerland) before embolization and were then followed up at 3 and 6 months after embolization.

Computed-tomography-based predictive scores of surgical complications to help decision-making in enrolling obese patients in kidney transplantation list.

This study aimed at developing scores predicting surgical complications in obese transplant recipients, based on preoperative computed tomography (CT) parameters. All consecutive patients with a body mass index (BMI) ≥ 30 kg/m who underwent kidney transplantation between 2012 and 2019 were included. The preoperative CT parameters were assessed: total fatty surface (TFS), subcutaneous fatty surface (SFS), iliac vessel to skin distance (VSD), and abdominal perimeter (AP).

Robotic Surgery For in situ Renal Artery Aneurysm Repair: Technical Note and Literature Review About a Mini- Invasive Alternative.

Case Report: Classical surgical options for renal artery aneurysm (RAA) are usually restricted to endovascular surgery or open repair, either using an in-situ or ex-situ approach. A 45-year-old woman presenting with a 20-mm complex RAA with hilum location, not suitable for endovascular repair renal was treated with a mini-invasive robotic approach. This approach allowed an in-situ reconstruction in a complete mini-invasive manner with the Da Vinci Xi robot (Intuitive Surgical, Sunnyvale, CA).

Radiation-induced lower-limb arteriopathy: report of 4 cases and systematic literature review.

Introduction: Radiation-induced arteriopathy (RIA) is a rare complication but may become more common due to the increased use of radiotherapy and the prolonged survival of patients. There is still a lack of evidence concerning treatment options. The aim of this study is to review reported cases of lower-limb RIA in order to provide guidelines for management.

Current status on vascular substitutes.

In the last decades, the main evolution in the field of vascular surgery was correlated to the development and introduction of vascular substitutes. Currently, two types of synthetic vascular substitutes have been widely adopted: polyethylene terephthalate and expanded polytetrafluoroethylene. Ideally, they should demonstrate a behavior as close as possible as that of human arteries in terms of mechanical and biological properties.

Compliance of Textile Vascular Prostheses Is a Fleeting Reality.

Objective: Compliance is considered to be a major property influencing the long term performances of synthetic vascular substitutes that could play a role in anastomotic false aneurysm and intimal hyperplasia stenosis onset. Over the last decades, manufacturers have tried to develop substitutes that mechanically mimic arterial properties and avoid a compliance mismatch at the anastomoses in particular. However, data are missing about how initial compliance properties could change with time.

Management of upper extremity aneurysms: a systematic review.

Introduction: The aim of this paper is to provide recommendations for diagnosis and management of arterial or venous aneurysms of the upper extremity.

Evidence Acquisition: A systematic review of the Medline and Cockrane databases was performed from 1988 to 2019 by a combined strategy of MeSh terms.

Evidence Synthesis: One-hundred-forty-four publications were identified: 111 addressing arterial aneurysms and 33 addressing venous aneurysms.

Volume Change after Endovascular Treatment of Common Iliac Arteries ≥ 17 mm Diameter: Assessment of Type 1b Endoleak Risk Factors.

Objective: The aim of this study was to assess the post-operative volumetric evolution of common iliac arteries (CIA) ≥ 17 mm diameter with respect to the type of endovascular technique performed and to assess type 1b endoleak risk factors.

Methods: All consecutive patients presenting with aneurysmal disease with CIA ≥17 mm treated endovascularly from 2008 to 2016 were included. Patients were divided into two groups dependent upon the type of endovascular technique performed: bell bottom technique (BBT group), vs.

Posterior Circumflex Humeral Artery Aneurysm: Case Report and Systematic Literature Review.

Posterior circumflex humeral artery (PCHA) aneurysm is a rare condition. It mostly affects young professional sports player and might be career threatening. This is the report of the case of a 28 year old volleyball player presenting with symptoms of right digital ischaemia caused by a PCHA aneurysm.

A Popliteal Cyst Responsible for Acute Lower Limb Ischemia.

We report the case of a 68-year-old man complaining of sudden intermittent claudication of the left limb. The patient was rapidly diagnosed with duplex ultrasound (DUS), computed tomography angiography, and magnetic resonance angiography as having a popliteal cyst (PC) compressing the popliteal artery, responsible for intermittent claudication. The patient underwent DUS-guided PC aspiration allowing symptoms resolution.

Endovascular Treatment for Venous Diseases: Where are the Venous Stents?

There is a growing need for dedicated endovascular devices to treat pathologies affecting the venous system. However, because of a lack of research into venous diseases and treatments, the optimal design, material, and mechanical properties of venous stents remain unknown. Development of the ideal venous stent should be based on a thorough understanding of the underlying venous pathology.

Open and Endovascular Repair of Popliteal Artery Aneurysms.

Background: The purpose of this study was to report midterm outcomes of open repair (OR) or endovascular repair (ER) of popliteal artery aneurysms (PAAs) and assess if outcomes of patients have changed in the endovascular era.

Methods: This monocentric and retrospective study included all consecutive patients treated for PAA between January 2004 and December 2016. Before 2010, all patients underwent OR, but ER was available since 2010, and the choice between OR or ER was made on the basis of clinical presentation and preoperative morphological assessment.
