Y-Radioembolization After Failed Portal Vein Embolization for Colorectal Liver Metastases: A Case Report.

The main limiting factor for liver resection is insufficient future liver remnant (FLR). Portal vein embolization (PVE) is a standard of care treatment to induce FLR hypertrophy, but it is not always efficient. Radioembolization (RE) has a potential to induce liver hypertrophy for PVE-refractory patients.

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.

Aortic rupture of acute aortic dissection type treated with thoracic endovascular aortic repair (TEVAR).

Objective: Acute aortic dissection (AAD) is one of the most frequent aortic emergencies, which occurs to the vascular specialist. Endovascular reconstruction of the true lumen using minimally invasive stent grafting or stenting has become increasingly popular and widespread among institutions. The aim of this paper is to report a case series composed by twenty-eight patients, who underwent endovascular intervention for acute type B aortic dissections complicated by rupture using thoracic endovascular aortic repair (TEVAR).

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.

High resolution 3-T MR imaging in the evaluation of the trigeminal nerve course.

Background: The evaluation of the trigeminal course and his anatomical relationships with surrounding structures, is important for the assessment of the injury that may occur in tumors and several orofacial trauma and for avoiding the damage during surgeries.

Aim: The aim of this retrospective study was to assess the use of 3-T MRI in the evaluation of the course of the four segments of the trigeminal nerve: cisternal and Meckels's cave, cavernous sinus, skull base and mandibular extracranial segments.

Patients And Methods: 78 patients were studied, for a total of 156 trigeminal nerves examined.

The use of high resolution magnetic resonance on 3.0-T system in the diagnosis and surgical planning of intraosseous lesions of the jaws: preliminary results of a retrospective study.

Background: The pre-operative evaluation in oral and maxillofacial surgery is currently performed by computerized tomography (CT). However in some case the information of the traditional imaging methods are not enough in the diagnosis and surgical planning. The efficacy of these imaging methods in the evaluation of soft tissues is lower than magnetic resonance imaging (MRI).

The impact of osteotomy technique for corticotomy-assisted orthodontic treatment (CAOT) on oral health-related quality of life.

Background: Corticotomy in accelerating orthodontic tooth movement, also defined as corticotomy-assisted orthodontic treatment (CAOT), is a promising technique that recently had many applications in orthodontics.

Aim: The purpose of this study was to compare the use of piezoelectric surgery and conventional rotatory osteotomy technique for CAOT, determining the duration of surgery and oral health-related quality of life (OHRQoL).

Patients And Methods: CAOT was performed in a sample of subjects, randomly choosing piezoelectric surgery (PS Group) or conventional rotary osteotomy technique (RT Group).

Treatment of facial vascular malformations with embolisation and surgical resection.

Introduction: Facial arteriovenous malformations (AVMs) are quite rare morbid conditions that clinically present themselves mainly as a massive bleeding or a significant aesthetic defect. Vascular malformations do not regress spontaneously; this is the reason why their resection is necessary. The successful treatment of these vascular anomalies is often compromised, since a high incidence of recurrence could be expected if the lesion is not managed properly.

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.

Qualitative comparison of MR TSE T2 and HASTE in temporomandibular disorders. Clinical observations.

Aim: The aim of the study is to evaluate the quality of the temporal mandibular joint (TMJ) imaging in patients with lack of condyle-disk coordination with the Half-Fourier Acquisition Single Shot Turbo Spin Echo (HASTE), and compare it with the quality of TSE T2-weighted images.

Methods: Twenty-seven patients were selected (12 men and 15 women; age range 17-69 years) with medical history negative for facial trauma or surgery. The instrument used was a Siemens 1.
