Background: Up to 1% of adults will have a leg ulcer at some time. Most leg ulcers are venous in origin and are caused by high pressure in the veins due to blockage or damaged valves. Venous ulcer prevention and treatment typically involves the application of compression bandages/stockings to improve venous return and thus reduce pressure in the legs.

CVI is characterised by valvular incompetence, reflux, venous obstruction or a combination of these symptoms, with consequent distal venous hypertension. Clinical manifestations of CVI include oedema, pain, skin changes, ulcerations and dilated skin veins in the lower limbs.

However, few studies have been conducted in Brazil to investigate the incidence of complications with these two types of catheters.
Objectives: To analyze complications and duration of CVCH in a hemodialysis center at a teaching hospital.
Background: The use of unfractionated heparin in hypovolemic shock, aortic clamping, and visceral reperfusion is still not established, despite evidence of inhibition of early cell damage. This study investigated the potential protective effect of unfractionated heparin on hepatic and renal apoptosis in a porcine ischemia and reperfusion model.
Methods: Twenty-one male swine (Sus scrofa) were divided into 3 groups: sham (n = 5), heparin (n = 8), and nonheparin (n = 8).

Procedures to eliminate incompetence and reflux in PV may include open surgery, subfascial endoscopic surgery, intravenous ablation techniques and sclerotherapy. With the aim of filling the evidence gap, this is a protocol for a systematic review that will assess the effects of any form of intervention for the treatment of pathologic PVs of the lower limbs in patients with chronic venous disease.

This study reports a giant symptomatic inferior mesenteric artery aneurysm and its endovascular treatment by means of percutaneous embolization with the implantation of pushable coils. After complete occlusion of the aneurysm, adequate maintenance of arterial supply of the left colon and resolution of the symptoms were observed.

Objectives: To analyze risk factors and survival associated with surgical and endovascular AAA treatment methods.
Methods: A retrospective, longitudinal study involving 41 patients who underwent endovascular or open AAA repair, whether elective or emergency, over a 48-month period, with analysis of preoperative comorbidities, 30-day and 1-year survival, in-hospital mortality, length of hospital stay, transfusion of blood products, duration of surgery, and development of acute kidney failure.
Background: Ultrasound-guided polidocanol foam sclerotherapy is used to treat patients with venous ulcers. It is a minimally invasive procedure and is simple to perform, but it has high relapse rates.
Objectives: To report short to medium term results in patients with venous ulcers treated using ultrasound-guided polidocanol foam sclerotherapy.
Background: Whether they are defined as minor or major, lower limb amputations constitute a severe health problem, causing high rates of morbidity and mortality and considerable social impact. Different patient clinical characteristics appear to be related to different types of amputations.
Objectives: To analyze risk factors present in patients who underwent lower limb amputations at a tertiary hospital.
The anatomy of the venous system of the lower limbs is among the most complex in the human body. In view of this, it is extremely important to know how to identify variations that can affect it, such as congenital malformations, for example. In cases of a rare vascular malformation such as agenesis of deep veins, clinical status may manifest with chronic venous insufficiency, which can progress with edema, hyperpigmentation, and lower limb ulcers.
