Hepatic involvement in hereditary hemorrhagic telangiectasia mimicking focal nodular hyperplasia.

Accurate diagnosis of hereditary hemorrhagic telangiectasia (HHT), also known as Rendu-Osler-Weber disease, is important for reducing the risk of complications. Hepatic involvement in HHT is usually asymptomatic, but when present can cause noted morbidity and mortality. A 62-year-old woman presented with moderate upper-abdominal pain and tachycardia. A diagnosis of HHT was made based on the findings of hepatic involvement in a contrast-enhanced abdominal computed tomography (CT) scan, the presence of arteriovenous malformations (AVMs; a.k.a. telangiectasias) on mucocutaneous surfaces, and a history of recurrent epistaxis. Imaging methods are important diagnostic tools in patients suspected of having HHT.

Results of Green Indocyanine in the Use of the R1T1 Robot as Aid in the Pre-operative Process of Hepatic Organ Transplant: Experiment in Wistar Rats.

Since the beginning of the history of transplants, numerous difficulties have been faced in the effective implementation of this therapeutic practice, especially with regard to the transplantation of solid organs and their teaching and training, together with the time of removal and transplantation of the organ that directly influences the results of the transplant surgical procedure. The objective of this research was to demonstrate the results found on the process of using green indocyanine during the invention of the Automatic Portable Surgical Communication Equipment with the Robot R1T1 (APSCERR), as well as to demonstrate its capabilities in the medical area of organ transplantation. Biochemical exams, liver profile exams, and mitochondrial breathing exams were performed on the control group and on the indocyanine group. The Mann-Whitney U test was used for statistical evaluations with a significance level of P < .05. As a result of this research, the effectiveness of using the APSCERR equipment on detecting the green indocyanine marker was proven, along with its ability to analyze macroscopic parameters together with the standard color "Dianin Boin scale" used to analyze the level of metabolism/reperfusion of the liver when observed with the APSCERR equipment connected to the R1T1 robot in the presence of green indocyanine. A patent for the development of APSCERR has been registered. It was possible to demonstrate the effectiveness of the equipment in detecting green indocyanine when analyzing parameters in the liver and the absence of a significant impact on the organ with the use of green indocyanine.
