Usefulness of ultrasound-guided tibio-pedal access in patients with critical limb ischemia.

Introduction: Retrograde access performed guided by fluoroscopy or ultrasound. We aimed to analyze the usefulness of ultrasound in retrograde access in patients with critical limb ischemia.

Methods: Observational analytical study.

Ultrasound Surveillance in Endovascular Revascularization of Lower Limbs.

Background: Endovascular surgery has become the initial treatment for most patients with chronic ischemia of the lower limbs. Few studies support ultrasound surveillance (US) of this kind of procedures. The purpose of this study was to evaluate the initial efficacy of duplex ultrasound as a surveillance method in endovascular treatment in symptomatic peripheral arterial disease patients in our center.

Contrast-Induced Nephropathy: A Fact or Fiction in Lower Limb Revascularization?

Introduction: Contrast-induced nephropathy (CIN) is defined as an increase >25% of serum creatinine from baseline, occurring in 24-48 hours after exposure to contrast, while alternative explanations for renal impairment have been excluded. The volume administered directly relates to risk, increasing by 12% per 100 mL of contrast. According to the series, its incidence varies between 3.
