A comprehensive study of right and left inferior phrenic artery variations in 1000 patients with multidetector computed tomography angiography: an important study for HCC.

PURPOSE: To investigate the anatomic variations in the origins of the right and left inferior phrenic arteries (IPAs) using multidetector computed tomography and to classify their combined variations. METHODS: This retrospective study included patients undergoing abdominal aorta angiography between January 2015 and October 2019. The RIPA and LIPA origins were evaluated both separately and combined on three-dimensional images. The variant patterns of the IPAs were determined and classified. The numerical evaluation of the data was performed with SPSS 21. RESULTS: In total, 1000 patients (478 women, 522 men) were evaluated. The IPAs originated from a common trunk or a common root in 360 (36.00%) patients, while the IPAs originated independently without a common trunk in 609 (60.90%) patients. The most common combined variant detected in the present study was IPAs originating as a common trunk from the coeliac trunk in 197 (19.70%) patients; 14 (1.40%) patients had no inferior phrenic artery (IPA), and 17 (1.70%) patients had only one IPA. CONCLUSION: Fifty-two different types of variations in the combined origin of the inferior phrenic arteries were described in this study for the first time in the literature. Awareness of the anatomic variations in the IPAs, which is critical for hepatocellular carcinoma origins, may benefit various clinical procedures, such as transcatheter arterial chemoembolization, organ transplantations, laparoscopic surgical procedures, and radiological procedures.

Distance measurements and origin levels of the coeliac trunk, superior mesenteric artery, and inferior mesenteric artery by multiple-detector computed tomography angiography.

The aim of this study is to determine vertebral levels of the coeliac trunk, the superior mesenteric artery, and the inferior mesenteric artery originated from the abdominal aorta and to calculate the distance measurements between these arteries and between these arteries and the aortic bifurcation by multidetector computed tomography angiography technique. It was determined that the nine different vertebral levels of the coeliac trunk, the nine different vertebral levels of the superior mesenteric artery, and the eleven different vertebral levels of the inferior mesenteric artery. The distance measurements between the coeliac trunk and the superior mesenteric artery, the inferior mesenteric artery, the aortic bifurcation were found significant between female and male. In this study, it was determined more different levels than the levels described in classical anatomy. The preoperative information of these morphological variations can contribute to the reduction of surgical time and perioperative vascular complications especially for anterior lumbar interbody fusion and defining the location of the primary lymphatic drainage site for gastrointestinal malignancies.

Investigation of proper hepatic artery and gastroduodenal artery variations by multidetector computed tomography angiography method.

Purpose: The purpose of this study is to evaluate the clinical anatomic variations of the proper hepatic artery (PHA) and the gastroduodenal artery (GDA). For this purpose, angiographic images of patients were evaluated.Materials and methods: We retrospectively reviewed the multiple-detector computed tomography angiography images of 671 patients.Results: In this retrospective study, 35 different types were identified as associated with PHA and GDA. There were 292 patients (43.52%; 175 females and 117 males) included in normal anatomical classification. Different anatomic variations were detected in 300 patients (44.71%; 129 females and 171 males). In 79 patients, arterial branch follow-up failed. These patients were evaluated as an unidentified group.Conclusion: We described different vascular variations in the PHAs and GDAs of our patients.

Immunoexpression of vascular endothelial growth factor, beta-cell lymphoma 2 and cluster of differentiation 68 in cerebellar tissue of rats treated with Ganoderma lucidum / Inmunoexpresión del factor de crecimiento endotelial vascular, linfoma de células beta 2 y grupo de diferenciación 68 en tejido cerebeloso de ratas tratadas con Ganoderma lucidum

Traumatic brain injury (TBI) can potentially lead to hemorrhages in all areas of the skull, which can damage cells and nerve connections. This study aims to investigate the protective effects of Ganoderma lucidum polysaccharides (GLPS) as a antioxidant on cerebellar cell tissues after traumatic brain injury in rats. Sprague Dawley rats were subjected to TBI with a weight-drop device using 300 g1m weight-height impact. The groups are consisted of control, trauma, and trauma+Ganoderma lucidum groups. At seven days post-brain injury, experimental rats were decapitated after intraperitoneal administration of ketamine HCL (0.15 ml/100 g body weight). Cereballar samples were taken for histological examination or determination of malondialdehyde (MDA) and glutathione (GSH) levels and myeloperoxidase (MPO) activity. Significant improvement was observed in cells and vascular structures of Ganoderma lucidum treated groups when compared to untreated groups. It is believed that Ganoderma lucidum may have an effect on the progression of traumatic brain injury. Ganoderma lucidum application may affect angiogenetic development in blood vessel endothelial cells, decrease inflammatory cell accumulation by affecting cytokine mechanism and may create apoptotic nerve cells and neuroprotective mechanism in glial cells.

La lesión cerebral traumática (LCT) puede provocar hemorragias en todas las áreas del cráneo, lo que puede dañar las células y las conexiones nerviosas. Este estudio tuvo como objetivo investigar los efectos protectores de los polisacáridos de Ganoderma lucidum (GLPS) como antioxidante en los tejidos de las células del cerebelo después de la lesión cerebral traumática en ratas. Ratas Sprague Dawley fueron sometidas a TBI con un dispositivo de caída de peso usando un impacto de peso de 300 g-1 m. Se formaron los siguientes grupos: control, trauma y trauma + Ganoderma lucidum. Siete días después de la lesión cerebral, las ratas experimentales fueron decapitadas después de la administración intraperitoneal de ketamina HCL (0,15 ml / 100 g de peso corporal). Se tomaron muestras cerebrales para el examen histológico y para la determinación de niveles de malondialdehído (MDA) y glutatión (GSH) y actividad de mieloperoxidasa (MPO). Se observó una mejora significativa en las células y las estructuras vasculares de los grupos tratados con Ganoderma lucidum en comparación con los grupos no tratados. Durante el estudio se observó que Ganoderma lucidum puede tener un efecto sobre la progresión de la lesión cerebral traumática. La aplicación de Ganoderma lucidum puede afectar el desarrollo angiogénico en las células endoteliales de los vasos sanguíneos, disminuir la acumulación de células inflamatorias al afectar el mecanismo de las citocinas y puede crear células nerviosas apoptóticas y un mecanismo neuroprotector en las células gliales.
