Analysis of infection rates and duration of short and long-term hemodialysis catheters in a teaching hospital.

Background: Short-term (ST) and long-term tunneled (LTT) central venous catheters for hemodialysis (CVCH) are critical for hemodialysis therapy. 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.

Risk factors and short and medium-term survival after open and endovascular repair of abdominal aortic aneurysms.

Background: Infrarenal abdominal aortic aneurysms (AAA) are responsible for high rates of rupture-associated morbidity and mortality and can be treated by open or endovascular surgery.

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: 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.
