CT and MR imaging of odontoid abnormalities: A pictorial review.

Odontoid process is the central pillar of the craniovertebral junction. Imaging of this small structure continues to be a challenge for the radiologists due to complex bony and ligamentous anatomy. A wide range of developmental and acquired abnormalities of odontoid have been identified. Their accurate radiologic evaluation is important as different lesions have markedly different clinical course, patient management, and prognosis. This article seeks to provide knowledge for interpreting appearances of odontoid on computed tomography (CT) and magnetic resonance imaging (MRI) with respect to various disease processes, along with providing a quick review of the embryology and relevant anatomy.

Feasibility and safety of same-day discharge after implantable cardioverter defibrillator placement for primary prevention.

BACKGROUND: In the current age of ever-increasing healthcare costs, it is of utmost importance to adopt strategies that reduce hospital stay and cost, while still maintaining patient safety. In this study we review our approach of same-day discharge following implantable cardioverter defibrillator (ICD) placement for primary prevention of sudden cardiac death (SCD). METHODS: We conducted a retrospective chart review of 415 consecutive patients who underwent ICD implantation for prevention of SCD between 2007 and 2010. Patients were divided into an outpatient group (Group A) and an inpatient group (Group B). We evaluated the patients' demographics, comorbidities, and the rate of short-term surgical complications on or before the 2-week follow-up appointment. RESULTS: Of 252 patients included in Group A, 198 (78.6%) were successfully discharged on the same day (Group A1). At the 2-week wound check appointment, four patients (2%) had minor surgical site bleeding, one patient had a hematoma, and one patient developed fever and swelling around the implantation site. Of the Group A patients, 54 (21.4%) were not discharged on the same day (Group A2). A total of 53 patients were included in Group B, four (7.5%) developed a hematoma at the 2-week follow-up wound check visit. CONCLUSIONS: Procedure-related complications after ICD placement are rare. Same-day discharge is safe and feasible following ICD placement for primary prevention of SCD and hence a reduction in healthcare costs can be achieved by decreasing the length of hospital stay.
