Analysis of 19 439 lower limb amputations in children in Brazilian health system over 14 years.

Background: Amputations in children represent significant events. Few studies analyse amputations in this specific population, and most of them are old, regionalised and with small sample sizes. Besides, there are no large studies in low-income and middle-income countries.

Preoperative evaluation profile of patients undergoing arterial vascular surgery in a tertiary hospital.

Background: Patients with peripheral arterial disease have an increased risk of developing cardiovascular complications in the postoperative period of arterial surgeries known as Major Adverse Cardiac Events (MACE), which includes acute myocardial infarction, heart failure, malignant arrhythmias, and stroke. The preoperative evaluation aims to reduce mortality and the risk of MACE. However, there is no standardized approach to performing them.

Dynamic computed tomography angiography for noninvasive diagnosis of bow Hunter's syndrome: a case report.

The focus of this case report is to technically describe a noninvasive diagnostic evaluation of bow Hunter's syndrome using a dynamic computed tomography angiography protocol and discuss its advantages. In addition, we aimed to exemplify the quality of the study by presenting images of a 3D-printed model generated to help plan the surgical treatment for the patient. The dynamic computed tomography angiography protocol consisted of a first image acquisition with the patient in the anatomic position of the head and neck.

Retrospective analysis of 1,203 cases of referral to a quaternary vascular surgery outpatient clinic within the Unified Health System, São Paulo, Brazil.

Objective: Through a retrospective analysis of 1,203 cases of referral from primary healthcare units to a specialized quaternary vascular surgical service, the findings of this study revealed a high proportion of inappropriate referrals, which may represent a substantial subutilization of this highly complex service. Consequently, in this study, we aimed to evaluate 1,203 cases of referral to a quaternary vascular surgical service, in São Paulo, Brazil, over a 6-year period, to assess the appropriate need for referral; in addition to the prevalence of surgical indications.

Methods: In this retrospective analysis, we reviewed the institutional records of participants referred from Basic Healthcare Units to a vascular surgical service inside the Brazilian Unified Health System, between May 2015 and December 2020.

Robot-assisted endovascular treatment of hepatic artery aneurysm: A case report.

Objective: Robot-assisted endovascular surgery has emerged as a new alternative to interventional procedures, with its application expanding to peripheral and visceral approaches. The objective of this paper is to describe a robot-assisted endovascular treatment in splanchnic arteries.

Methods: A case report of an asymptomatic male patient with an incidental finding of a saccular aneurysm of the proper hepatic artery measuring 3.

Editor's Choice - Analysis of Lower Limb Amputations in Brazil's Public Health System over 13 Years.

Objective: Understanding the causes of amputation is crucial for defining health policies that seek to avoid such an outcome, but only a few studies have investigated the epidemiology of patients submitted to amputations in developing countries. The objective of this study was to analyse all lower limb amputations performed in the public health system in Brazil over a 13 year period, evaluating trends in the number of cases, patient demographics, associated aetiologies, hospital length of stay, and in hospital mortality rate.

Methods: This was a retrospective, population based analysis of all lower limb amputations performed in the Brazilian public health system between 1 January 2008 and 31 December 2020.

National Cross-Sectional Epidemiological Analysis of the Impact of Pandemic COVID-19 on Vascular Procedures in Public Health System: 521,069 Procedures Over 4 Years.

Background: During the COVID-19 pandemic, there was a dramatic increase in healthcare demand. Resources were redirected to care patients with COVID-19. Therefore, surgical treatments were affected, including those of vascular diseases.

Proposed public policies to improve outcomes in vascular surgery: an experts' forum.

Objective: To evaluate outcomes of vascular surgeries and identify strategies to improve public vascular care.

Methods: This was a descriptive, qualitative, and cross-sectional survey involving 30 specialists of the Hospital Israelita Albert Einstein via Zoom. The outcomes of vascular procedures performed in the Public Health System extracted through Big Data analysis were discussed, and 53 potential strategies to improve public vascular care to improve public vascular care.

Intraoperative evaluation of tunneled dialysis catheter mobility and function with arm movement.

Objective: The main objectives of the present study were to analyze the right internal jugular vein tunneled dialysis catheter (TDC) tip displacements, functional changes, pathway deformities, and angulations associated with different arm positions.

Methods: We prospectively studied 21 patients who had undergone TDC implantation for hemodialysis via the right internal jugular vein at a single center from February to September 2020. After implantation, a baseline resting fluoroscopy image was taken, and three movement-mimicking images of the ipsilateral arm were obtained for comparison, with the arm in maximum abduction, maximum flexion, and maximum adduction.
