Multidisciplinary approach to pelvic leiomyomatosis with intracaval and intracardiac extension: A case report and review of the literature.

Intravenous leiomyomatosis (IVL) is an uncommon variant of leiomyoma characterized by intravascular proliferation of a histologically benign smooth muscle tumor extending beyond the uterus into the distant great vessels. Leiomyomatosis may reach the inferior vena cava, right atrium, and pulmonary arteries. Owing to its rare occurrence, intracardiac leiomyomatosis has been reported as isolated case reports and small case series.

One-year results of the ANCHOR trial of EndoAnchors for the prevention and treatment of aortic neck complications after endovascular aneurysm repair.

Objectives: EndoAnchors have been used to address proximal aortic neck complications including type Ia endoleaks and endograft migration after endovascular aortic aneurysm repair (EVAR).

Methods: The study population included 100 patients with one-year follow-up in the ANCHOR study. A primary cohort (N = 73) comprised patients who underwent EndoAnchor implantation at the time of an initial EVAR and a Revision cohort (N = 27) included patients treated remote from EVAR.

Midterm outcome of EndoAnchors for the prevention of endoleak and stent-graft migration in patients with challenging proximal aortic neck anatomy.

Purpose: To explore the use of EndoAnchors as an adjunct to endovascular abdominal aortic aneurysm repair for prevention of proximal neck complications in patients with challenging neck anatomy.

Methods: Over a 28-month period, 208 patients (159 men; mean age 72±8 years) were enrolled in the ANCHOR prospective, multicenter registry (ClinicalTrials.gov; identifier NCT01534819) for prophylaxis against proximal neck complications.

Outcome-based anatomic criteria for defining the hostile aortic neck.

Objective: There is abundant evidence linking hostile proximal aortic neck anatomy to poor outcome after endovascular aortic aneurysm repair (EVAR), yet the definition of hostile anatomy varies from study to study. This current analysis was undertaken to identify anatomic criteria that are most predictive of success or failure at the aortic neck after EVAR.

Methods: The study group comprised 221 patients in the Aneurysm Treatment using the Heli-FX Aortic Securement System Global Registry (ANCHOR) clinical trial, a population enriched with patients with challenging aortic neck anatomy and failure of sealing.

Analysis of EndoAnchors for endovascular aneurysm repair by indications for use.

Objective: The proximal aortic neck remains one of the challenges of endovascular aneurysm repair (EVAR), and the risk of type Ia endoleak and endograft migration is increased in patients with short, large-diameter, or highly angulated necks. EndoAnchors have been used as an adjunct to EVAR in such patients, and the aim of this study was to assess their benefit analyzed by indication for use.

Methods: During a 2-year period, 319 patients were enrolled at 43 sites in the Aneurysm Treatment Using the Heli-FX Aortic Securement System Global Registry (ANCHOR) study.

Results of the ANCHOR prospective, multicenter registry of EndoAnchors for type Ia endoleaks and endograft migration in patients with challenging anatomy.

Objective: Proximal attachment site complications continue to occur after endovascular repair of abdominal aortic aneurysms (EVAR), specifically type Ia endoleak and endograft migration. EndoAnchors (Aptus Endosystems, Sunnyvale, Calif) were designed to enhance endograft proximal fixation and sealing, and the current study was undertaken to evaluate the potential benefit of this treatment.

Methods: During the 23-month period ending in December 2013, 319 subjects were enrolled at 43 sites in the United States and Europe.

The issue of spontaneous arteriovenous fistulae after superficial thrombophlebitis, endovenous ablations, and deep vein thrombosis: an unusual but predictable finding.

Spontaneous arteriovenous fistulae develop after the formation of venous thrombi in animals. In patients who have undergone endovenous ablation, angiogenesis occurs. This study was undertaken to examine the clinical presentation, development, and effects of spontaneous arteriovenous fistulae in patients with venous thrombosis.
