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.

Role of Botulinum Toxin in Pectoralis Minor Syndrome.

Background: Thoracic outlet syndrome (TOS) causes neurogenic symptoms in 95% of the cases due to neurovascular bundle compression. The treatment goal is the decompression of the neurovascular structures. In the last decade, non-surgical treatments have been evaluated as a treatment option for spastic syndromes and thoracic outlet syndrome.

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.

Role of an age-adjusted D-dimer cutoff level in the diagnosis algorithm of lower limb deep venous thrombosis in outpatients.

Objective: Our goal was to analyze the utility of the age-adjusted D-dimer cutoff value in patients with clinically suspected deep venous thrombosis (DVT) in an ambulatory care setting, including distal DVTs.

Methods: This was an observational cohort study of 606 outpatients older than 18 years presenting with low or moderate clinical suspicion of lower limb DVT (measured by Wells scale). D-dimer levels were obtained, and duplex ultrasound was performed (including femoropopliteal and below-knee veins).

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.

[Long-term treatment with a low-molecular-weight heparin administered subcutaneously compared with a vitamin K antagonist: subanalysis of patients with cancer].

We performed a subanalysis of cancer patients enrolled in a clinical trial that compared long-term (6 months) treatment with a low-molecular-weight heparin (LMWH) administered subcutaneously or with acenocoumarol. The subanalysis assessed whether the characteristics of the tumor had an influence on the clinical response. A randomized open trial included 69 patients with cancer and symptomatic proximal deep vein thrombosis of the lower limbs.

[Deep venous thrombosis as a marker of tumor recurrence].

Background And Objective: There is a bidirectional association between neoplasia and venous thromboembolism (VTE). However, whether this association has an impact in tumor recurrence is unknown. The aim of the study is to assess the incidence of cancer recurrence after diagnosis of VTE and determine if VTE could be a marker for cancer recurrence.

The role of color duplex sonography in the diagnosis of giant cell arteritis.

Objective: To determine the clinical usefulness of color duplex sonography in the diagnosis of giant cell arteritis as an alternative to temporal artery biopsy.

Methods: From May 1998 to November 2002, 68 consecutive patients seen in our hospital with a clinical suggestion of active temporal arteritis were included. Forty-eight patients were female and 20 were male, with a mean age of 77 years.
