Method: A retrospective review of patients who were endovascularly treated for ischemic foot ulcers between January 2015 and May 2017. Technical success was defined as arterial recanalization with stenosis less than 30 % and ankle brachial index improvement by > 0.

Secondary interventions after fenestrated and branched endovascular repair of complex aortic aneurysms.

Objective: The use of fenestrated and branched endografts for the treatment of complex aortic aneurysms is increasing. Despite the low morbidity and mortality associated with these repairs, reintervention rates in the midterm and long term remain a concern. The purpose of this study was to investigate our experience with reinterventions after fenestrated and branched endovascular aneurysm repair (F/BEVAR).

Selective Arterial Embolization for Large or Symptomatic Renal Angiomyolipoma: 10 Years of Follow-up.

Objective: To assess long-term outcome after selective arterial embolization (SAE) as first-line treatment for large or symptomatic AML.

Design, Setting, And Participants: Data from a prospectively maintained database on 71 patients who underwent SAE for large or symptomatic AML were reviewed. Patients with sporadic and tuberous-sclerosis-complex (TSC) were included.

Venous Malformations Sclerotherapy: Outcomes, Patient Satisfaction and Predictors of Treatment Success.

Purpose: To retrospectively evaluate the results of sclerotherapy for venous malformations, with emphasis on patient satisfaction, complications and predictors of positive response to treatment.

Materials And Methods: Three hundred and nine patients were treated with ethanol sclerotherapy for venous malformations in our center between the years 2000 and 2014. All of them were sent a self-assessment questionnaire for evaluation of their satisfaction and treatment complications.

The use of optional inferior vena cava filters of type Optease in trauma patients--a single type of filter in a single Medical Center.

Background: Venous thromboembolism (VTE) is a frequent complication of patients who experienced major trauma. Prevention of VTE is usually by thrombophylaxis and or by the use of a retrievable filter. Lately, the use of a retrievable filter in trauma patients has increased despite evidence cautioning against its use.

Patients And Methods: Twenty-two symptomatic patients (11 men and 11 women, age range 51 to 88 years) with intrahepatic or common bile duct calculi underwent PTBL. Nine patients had undergone previous gastrectomy and small-bowel anastomosis, thus precluding endoscopic retrograde cholangiopancreatography.

Optease vena cava filter optimal indwelling time and retrievability.

The purpose of this study was to assess the indwelling time and retrievability of the Optease IVC filter. Between 2002 and 2009, a total of 811 Optease filters were inserted: 382 for prophylaxis in multitrauma patients and 429 for patients with venous thromboembolic (VTE) disease. In 139 patients [97 men and 42 women; mean age, 36 (range, 17-82) years], filter retrieval was attempted.

Histology of tissue adherent to OptEase inferior vena cava filters regarding indwelling time.

The purpose of this paper is to report on the histology of tissues found on retrieved filters with regard to indwelling time. Between February 2006 and January 2007, 28 Optease inferior vena cava filters (Cordis Europa, Roden, The Netherlands) were retrieved from 27 patients. Twenty-two filters were inserted prophylactically for trauma patients and six for patients with venous thromboembolism.
