Strain Ultrasound Elastography of Aneurysm Sac Content after Randomized Endoleak Embolization with Sclerosing vs. Non-sclerosing Chitosan-based Hydrogels in a Canine Model.

Purpose: To compare the mechanical properties of aneurysm content after endoleak embolization with a chitosan hydrogel (CH) with that with a chitosan hydrogel with sodium tetradecyl sulfate (CH-STS) using strain ultrasound elastography (SUE).

Materials And Methods: Bilateral common iliac artery type Ia endoleaks were created in 9 dogs. Per animal, 1 endoleak was randomized to blinded embolization with CH, and the other, with CH-STS.

Association of Lower Diagnostic Yield With High Users of CT Pulmonary Angiogram.

This study examines interphysician variability of diagnostic yield in computed tomographic pulmonary angiogram for pulmonary emboli.

Use of cardiovascular magnetic resonance in the evaluation of a giant right atrial appendage aneurysm: a case report and review of the literature.

Background: Right atrial appendage aneurysms are rare entities that may have significant clinical consequences. When co-existing with atrial fibrillation, patients are at risk of developing pulmonary or paradoxical systemic emboli.

Case Presentation: An elderly patient presented to medical attention with symptoms of acute diverticulitis.

Chitosan-doxycycline hydrogel: An MMP inhibitor/sclerosing embolizing agent as a new approach to endoleak prevention and treatment after endovascular aneurysm repair.

Unlabelled: The success of endovascular repair of abdominal aortic aneurysms remains limited due to the development of endoleaks. Sac embolization has been proposed to manage endoleaks, but current embolizing materials are associated with frequent recurrence. An injectable agent that combines vascular occlusion and sclerosing properties has demonstrated promise for the treatment of endoleaks.

Utility and costs of radiologist interpretation of perioperative imaging in patients with traumatic single-level thoracolumbar fractures.

OBJECTIVE The cost of spine management is rising. As diagnostic imaging accounts for approximately 10% of total patient care spending, there is interest in determining if economies could be made with regard to the routine consultation of radiology for image interpretation. In the context of spine trauma, both the spine surgeon and the radiologist interpret perioperative imaging.

Liver segmentation: indications, techniques and future directions.

Objectives: Liver volumetry has emerged as an important tool in clinical practice. Liver volume is assessed primarily via organ segmentation of computed tomography (CT) and magnetic resonance imaging (MRI) images. The goal of this paper is to provide an accessible overview of liver segmentation targeted at radiologists and other healthcare professionals.

Aortic Calcification Progression in Heterozygote Familial Hypercholesterolemia.

Background: Patients with homozygous and heterozygous familial hypercholesterolemia (HeFH) develop severe aortic calcifications in an age- and gene dosage-dependent manner. The purpose of this study was to determine the rate of progression of aortic calcification in patients with HeFH.

Methods: We performed thoracoabdominal computed tomography scans and quantified aortic calcium (AoCa) score in 16 HeFH patients, all with the null low-density lipoprotein (LDL) receptor DEL15Kb mutation.

Support infrastructure available to Canadian residents completing post-graduate global health electives: current state and future directions.

Background: Global health electives offer medical trainees the opportunity to broaden their clinical horizons. Canadian universities have been encouraged by regulatory bodies to offer institutional support to medical students going abroad; however, the extent to which such support is available to residents has not been extensively studied.

Methods: We conducted a survey study of Canadian universities examining the institutional support available to post-graduate medical trainees before, during, and after global health electives.

An enhanced recovery pathway reduces duration of stay and complications after open pulmonary lobectomy.

Background: Few studies have investigated the effectiveness of enhanced recovery pathways (ERP) for lung resection. This study estimates the impact of an ERP for lobectomy on duration of stay, complications, and readmissions.

Methods: Patients undergoing open lobectomy were identified from an OR database between 2011 and 2013.
