Initial single-site experience with the Ovation abdominal stent-graft system in patients with challenging aortoiliac anatomy.

Background: Aim of the study was to evaluate the initial results of endovascular aneurysm repair with the Ovation abdominal stent-graft system in patients with challenging aortoiliac anatomy.

Methods: The Ovation stent-graft is an ultra-low profile, modular endovascular graft characterized by a 14F OD delivery system, active suprarenal fixation, and polymer-filled proximal rings that allow sealing in short (≥7 mm) proximal necks. Between November 2010 and January 2012, 14 patients with abdominal aortic aneurysms (AAA) (male: 100%, mean age: 76 years, mean AAA diameter: 54 mm) and challenging aortoiliac anatomy were treated with the Ovation endograft at a single centre.

Evaluation of Highly Porous Dental Implants in Postablative Oral and Maxillofacial Cancer Patients: A Prospective Pilot Clinical Case Series Report.

Purpose: The aim of this study was to evaluate the clinical efficacy of new porous tantalum trabecular metal (PTTM)-enhanced titanium dental implants used for the prosthodontic rehabilitation of postablative cancer patients. First-year interim results of a prospective clinical case series are presented.

Materials And Methods: A total of 25 PTTM-enhanced titanium implants were placed in both maxillas and mandibles of 6 patients, who met specific inclusion criteria.

Treatment of high-flow arteriovenous malformations (AVMs) of the head and neck with embolization and surgical resection.

Aim: Arteriovenous malformations (AVMs) with a high flow of the head and neck are quite rare compared to their low-flow counterparts, but when they do occur they are often accompanied by massive bleeding or present with significant esthetic defects. The treatment of these high-flow vascular anomalies is often highly risky. The multidisciplinary approach required for the assessment and treatment of these lesions should include angioradiology with preoperative superselective embolization, followed by surgical resection of the lesion within 24 hours and esthetic reconstruction.

A comparative study of Magnetic Resonance (MR) and Computed Tomography (CT) in the pre-implant evaluation.

Aim: A successful implant therapy is based on an accurate assessment of the anatomy of the jaws. The aim of our study was to evaluate the reliability of magnetic resonance imaging (MR) compared with computed tomography (CT) for dental implant planning in respect to bone measurements and to observe and analyze the differences.

Method: We have studied 30 cases in which scans were performed with CT and MR.
