Resistance Index as a Prognostic Factor for Patency in Distal Lower Limb Arterial Revascularization.

Background: Critical limb ischemia (CLI) of the lower limbs (LLs) is a severe condition caused by peripheral arterial obstructive disease (PAOD). Surgical planning for CLI requires the study of limb circulation, and the vascular resistance index (RI) measured by Doppler ultrasound (US) has been used to aid in surgical decision-making. The objective is to correlate the RI of recipient arteries with the patency of LL revascularization surgeries in patients with CLI.

Vascular resistance index and the immediate hemodynamic success of lower limb distal artery revascularization.

Background: Revascularization surgery is used to attempt to restore blood flow to the foot in patients with critical ischemia (CI) caused by peripheral arterial occlusive disease of the lower limbs (LL). Ultrasonography with Doppler (USD) SAH emerged in recent years as a highly valuable method for planning this surgical intervention.

Objectives: To evaluate the relationship between the resistance index (RI), measured with USD, and immediate hemodynamic success of LL revascularization surgery in patients with CI.

Correlation between the vascular resistance index and arteriography for assessment of the distal arterial bed in chronic limb threatening ischemia.

Background: Patients with chronic limb threatening ischemia (CLTI) of the lower limbs (LL) undergo arteriography for revascularization surgery planning. Doppler ultrasound (DU) is non-invasive and can provide information about the distal arteries through measurement of the resistance index (RI).

Objectives: To correlate the Rutherford Angiographic Classification with the RI for assessment of the distal arterial bed of the LL.

Bacterial cellulose biomaterials for the treatment of lower limb ulcers.

This scenario encourages the development of new, low-cost therapeutic alternatives. The present study aims to describe the use of bacterial cellulose in the treatment of lower limb ulcers.

Effect of Obesity and Bariatric Surgery on Saphenous Veins.

Purpose: Obesity is a risk factor for chronic venous disease (CVD) of the lower limbs (LL), affecting venous anatomy and physiology. Weight loss after bariatric surgery (BS) can reduce intra-abdominal pressure, improve mobility, and ultimately improve venous hemodynamics and CVD-related symptoms. There are no studies in the literature that adequately assess the effect of the obesity and BS on the LL veins, especially the saphenous veins (SV).

Materiais E MÉtodos: Foram analisados dados de prontuários de 956 pacientes submetidos a transplante renal, no período de 2013 a 2018, em um centro transplantador renal do nordeste do Brasil. Nos pacientes que desenvolveram pneumonia, os agentes etiológicos foram classificados em bactérias piogênicas, micobactérias, fungos, vírus e pneumonia polimicrobiana, enquanto os padrões tomográficos foram classificados em consolidação, broncopneumonia, pneumonia intersticial e nódulos e massas.

Bacterial cellulose an effective material in the treatment of chronic venous ulcers of the lower limbs.

Chronic venous ulcers (CVU) of the lower limbs (LL) are common and cause psychological changes and significant social impact, as they make the patient susceptible to pain, absence from work and social bonds. Some materials are suggested as dressings for the treatment of CVU, but they are expensive and are generally not available for use in public health services. To evaluate the efficacy of the treatment for lower limbs (LL) chronic venous ulcer (CVU) using bacterial cellulose (BC), gel and multi-perforated film associated.

Quality of life assessment before and after surgery for lower limb varicose veins.

Background: Lower limb varicose veins are one of the most prevalent diseases in the global population. The disease is chronic and has a great impact on patients' quality of life, limiting daily activities and functional performance. Several authors have emphasized the importance of including quality of life assessment in management of patients with chronic venous disease.

Nursing in mechanical prevention of venous thromboembolism in surgical patients.

Objective: This theoretical study aims to discuss the role of nurses in the mechanical prevention of venous thromboembolism in surgical patients.

Method: The study considered the updated versions of the main international guidelines and reviews on the topic. Non-pharmacological measures to prevent venous thromboembolism in surgical patients and the role of nurses are discussed.

Evaluation of pentoxifylline and ferrous sulfate for treatment of lower limb venous ulcers.

Background: Venous ulcers (VU) are the most advanced stage of chronic venous disease (CVD) of the lower limbs. They are frequently associated with episodes of hemorrhage that can provoke chronic anemia (CA), delaying healing. There are no studies in the literature analyzing the prevalence of CA among patients with VU of the lower limbs and few studies have analyzed use of pentoxifylline to treat VU of the lower limbs.

COVID-19 and obesity: the meeting of two pandemics.

COVID-19 and obesity are two pandemic diseases that the world is currently facing. Both activate the immune system and mediate inflammation. A sequence of disease phases in patients with severe COVID-19 results in a cytokine storm, which amplifies the subclinical inflammation that already exists in patients with obesity.

Bacterial cellulose biopolymer film and gel dressing for the treatment of ischemic wounds after lower limb revascularization.

Objective: to evaluate the use of a bacterial cellulose biopolymer film and gel dressing in the treatment of patients with ischemic wounds submitted to lower limb revascularization.

Methods: we conducted a randomized clinical trial in the Angiology and Vascular Surgery outpatient clinic of the Clinics Hospital of the Federal University of Pernambuco, between January 2017 and December 2018. We followed 24 patients after lower limb revascularization, divided into two groups: Experimental, treated with bacterial cellulose biopolymer film and gel, and Control, treated with essential fatty acids.

We randomly assigned patients to two groups: control group, receiving dressings with triglyceride oil (11 patients) and experimental group, treated with BC membrane (14 patients).

Lymphoscintigraphic abnormalities in the contralateral lower limbs of patients with unilateral lymphedema.

Objective: The contralateral limbs of patients with unilateral lymphedema in the lower limbs (LLs) can exhibit abnormal lymphatic circulation, even in the absence of lymphedema. This idea is based on a number of reports that have studied isolated cases using lymphoscintigraphy. It is likely that these patients previously had some form of lymphopathy, and the lymphedema arose after the action of some external factor.
