Pseudoaneurisms are arterial wounds that affect all layers of an artery;although very rare they are mostly lethal and most of them are iatrogenic. Herein, we present two different cases of hepatic artery pseudoaneurysms derived from previous surgeries which were assessed by computed tomography angiographies and consequent conservative endovascular approaches with arteriographies, posterior cannulations and the placement of Amplatzer Vascular Plug 4 (AVP 4) systems in order to treat the pseudoaneurysm. Computed control tomographies were conducted showing no later complications. The purpose of this article is to demonstrate the importance and current clinical applications of AVP in the field of interventional radiology.

According to various studies, it has been found that due to the lack of reagents for the RT-PCR test for the accurate diagnosis of sARs-CoV-2 infection, tomography began to be used as a criterion to achieve diagnostic support in patients with lack of a definitive diagnosis. The objective of this work is to describe the tomographic findings in patients with COVID-19 and their relationship with the clinical presentation in each of the radiological patterns. According to the Feinstein Criteria, the analytical type of study, with quantifiable, non-experimental data, was cross-sectional from October 2020 to June 2021, obtaining a sample of 227 patients hospitalized in the UAER of the CmJPP. statistical analysis was performed using microsoft Excel (2021) and sPss. According to the radiological classifications, 6.17% (14) presented in the Initial (early) phase of the disease, 46.7% (106) were in progression and 47.14% (107) in the advanced phase of the latter with a higher percentage in the CORADs classification at level 3 with 74.5% in both;similarly, in advanced onset, the extension with the greatest presentation was severe with 86.96% (93). Tomographic studies played an important role during the COVID-19 pandemic, together with the application of international classifications such as CO-RADs and the classification issued by INER, being considered diagnostic support tools for COVID-19 and patient evolution.

Obtaining Bioethanol through Hydrolytic Treatment of Agro-Industrial Banana Residues

The banana is a food of great importance and it is consumed in almost the entire world. However, its harvest generates large quantities of mostly lignocellulosic waste, which can be used for the production of biofuels such as bioethanol. In this work, the potential for bioethanol production from agro-industrial plantain crop residues was evaluated with different operating conditions. A 24?experimental design was used, having as study variables: time of hydrolysis, pH of hydrolysis, concentration time, and fermentation time. The samples used were scraps consisting of a mixture of stems, leaves, and banana peels. The bioethanol obtained was characterized by physicochemical properties such as density, refractive index, and FTIR. As a result, it was obtained that the volume of bioethanol represented higher yields;using NaOH as a hydrolyzing agent, with hydrolysis time of 30 minutes, high fermentation time, and low concentrations. The chemical characterization of banana agro-industrial waste indicated that, the raw material could be considered as a potential source for bioethanol production, since it has a high content of cellulose.
