Mesenteric Amyloidosis: Radiologic Imaging with Pathologic Correlation.

Amyloidosis is a rare disease that is characterized by abnormal deposition of amyloid proteins in tissues, resulting in local, or systemic disease. When localized, it can present as an amyloidoma. We report a case of mesenteric amyloidosis in an 80-year-old male who was found to have an incidental mesenteric mass that was biopsy-proven to represent non-light chain amyloid tissue.

Treatment of superior vena cava syndrome with kissing brachiocephalic stents and exchange of pacemaker leads.

Superior vena cava syndrome is an uncommon but challenging complication of patients undergoing hemodialysis through upper extremity access as well as of patients with indwelling pacemakers. This case report and Video demonstrate the multidisciplinary management of a complex patient with hemodialysis access and indwelling pacemaker for whom multiple attempts at balloon angioplasty for superior vena cava syndrome failed. A joint procedure between vascular surgery and cardiac electrophysiology teams was performed to exchange the pacemaker leads and to place bilateral kissing stents in the brachiocephalic veins.

Characterizing patterns of endothelialization following coil embolization: a whole-mount, dual immunostaining approach.

Background: The extent, rate, and source of endothelialization following coil embolization of saccular aneurysms remains poorly understood. We performed a whole tissue mount, dual immunohistochemical analysis of experimental aneurysms to characterize the state of endothelialization over time after platinum coil embolization.

Method And Material: Elastase-induced rabbit aneurysms were created and treated with bare platinum coils.

Elastase-induced intracranial dolichoectasia model in mice.

Background: Intracranial dolichoectasia is associated with high morbidity, and its pathophysiology remains poorly understood.

Objective: To develop a technique for the creation of a murine model of dolichoectasia.

Methods: C57/BL6 mice were injected with 0 milliunit (mu) (control, n = 5), 15 mu (n = 7), 25 mu (n = 10), 35 mu (n = 10), and 55 mu (n = 6) of elastase in the cisterna magna.

Cellular mechanisms of aneurysm occlusion after treatment with a flow diverter.

Purpose: To characterize the progression of healing across aneurysm necks following treatment with a flow diverter in a rabbit aneurysm model.

Materials And Methods: With institutional animal care and use committee approval, saccular aneurysms were created in 20 rabbits and treated with flow diverters. On days 1, 3, and 7 and weeks 4 and 8 after implantation, the aneurysm and the device-implanted vessel were harvested.

'Initial Clinical Experience' articles are poorly cited and negatively affect the impact factor of the publishing journal: a review.

Objectives: The phrase 'Initial Clinical Experience' in a manuscript's title implies that the described technique offers promise of future clinical relevance. We assessed, using rates of subsequent citations, the actual academic relevance of such articles in comparison to articles not containing the phrase.

Design: We searched ISI database for articles that included the studied phrase in their titles between 1975 and 2009 and grouped the results by the related medical specialty.

Healing of saccular aneurysms following platinum coil embolization: lack of improved efficacy with vitamin C supplementation.

Background And Purpose: To test the hypothesis that systemic administration of vitamin C, through its action of stimulating collagen synthesis and crosslinking, would decrease the recurrence and improve the occlusion of experimental aneurysms treated with platinum coils.

Methods: Experimental aneurysms were created in female rabbits and were embolized with platinum coils (>30% packing density). The animals were divided into three groups: group 1 (n=6) rabbits served as controls, group 2 (n=5) rabbits were fed with a vitamin C supplemented feed and group 3 (n=8) rabbits were medicated with vitamin C pills.

Pre-residency publication rate strongly predicts future academic radiology potential.

Rationale And Objectives: Radiology resident selection committees often favor candidates with strong academic potential. The aim of this study was to determine if preresidency academic productivity of current radiologists was predictive of subsequent of future academic performance.

Materials And Methods: The academic productivity of all radiology residents trained between 1975 and 2005 at the authors' institution was assessed through identification of their publication histories, National Institutes of Health funding statuses, and Hirsch indexes (h-indexes).

Is the h-index predictive of greater NIH funding success among academic radiologists?

Rationale And Objectives: Despite rapid adoption of the Hirsch index (h-index) as a measure of academic success, the correlations between the h-index and other metrics of productivity remain poorly understood. The aims of this study were to determine whether h-indices were associated with greater National Institutes of Health (NIH) funding success among academic radiologists.

Materials And Methods: Using the Scopus database, h-indices were calculated for a random sample of academic radiologists with the rank of professor.
