Comparison of Liquid to Particle Embolics in a Translational Rat Model of Hepatocellular Carcinoma: Histologic and Radiographic Responses.

Purpose: To compare the effectiveness of transarterial embolization (TAE) using a liquid embolic (LE) to TAE using a particle embolic (PE) based on radiographic and histologic response in a translational rat model of hepatocellular carcinoma (HCC).

Materials And Methods: HCC was induced in Wistar rats using diethylnitrosamine. Tumor response was determined through RECIST applied to T2-weighted MRI scans.

The impact of the COVID-19 pandemic on acute appendicitis patients in a tertiary care center in Lebanon.

Introduction: With it becoming a global pandemic, the coronavirus disease of 2019 (COVID-19) imposed public health restraints that hampered patient's presentation to hospitals. In Lebanon, little is known about the presentation patterns of acute appendicitis (AA) patients among different population groups during the COVID-19. Therefore, this study aims to assess the effects of the COVID-19 pandemic on the rates of cases seen during the pandemic period, the adopted management strategies, and evaluate the patient outcomes compared to presentations from previous years.

Trigeminal neuralgia secondary to onyx embolization of a right occipital arteriovenous malformation.

Background: Trigeminal neuralgia is a debilitating chronic condition characterized by severe recurrent hemifacial pain which is often caused by compression of the trigeminal nerve by an adjacent vessel loop. Microvascular decompression (MVD) surgery is an effective procedure that can lead to full symptomatic relief. Intracranial arteriovenous malformations (AVMs) are primarily congenital abnormalities that may be asymptomatic or manifest as seizures or focal neurologic deficits.
