Anatomic Pathways of Peripancreatic Fluid Draining to Mediastinum in Recurrent Acute Pancreatitis: Visible Human Project and CT Study
PloS one, 2013Co-Authors: Xiao-ming Zhang, Shaoxiang Zhang, Andreas Christe, Lukas Ebner, Zhulin Luo, Fuzhou TianAbstract:BACKGROUND In past reports, researchers have seldom attached importance to achievements in transforming digital anatomy to radiological diagnosis. However, investigators have been able to illustrate communication relationships in the retroperitoneal space by drawing potential routes in computerized tomography (CT) images or a virtual anatomical atlas. We established a new imaging anatomy research method for comparisons of the communication relationships of the retroperitoneal space in combination with the Visible Human Project and CT images. Specifically, the anatomic pathways of peripancreatic fluid extension to the mediastinum that may potentially transform into fistulas were studied. METHODS We explored potential pathways to the mediastinum based on American and Chinese Visible Human Project datasets. These drainage pathways to the mediastinum were confirmed or corrected in CT images of 51 patients with recurrent acute pancreatitis in 2011. We also investigated whether additional routes to the mediastinum were displayed in CT images that were not in Visible Human Project images. PRINCIPAL FINDINGS All hypothesized routes to the mediastinum displayed in Visible Human Project images, except for routes from the retromesenteric plane to the bilateral retrorenal plane across the bilateral fascial trifurcation and further to the retrocrural space via the Aortic Hiatus, were confirmed in CT images. In addition, route 13 via the narrow space between the left costal and crural diaphragm into the retrocrural space was demonstrated for the first time in CT images. CONCLUSION This type of exploration model related to imaging anatomy may be used to support research on the communication relationships of abdominal spaces, mediastinal spaces, cervical fascial spaces and other areas of the body.

(A) The potential Route 5 to Route 9 is shown in the superior mesenteric artery section. Route 5 (white arrows) is from the retromesenteric plane to the left retrorenal plane via the left bridging septa, and further into the retrocrural space across the Aortic Hiatus; Route 6 is present as the similar conduit on the opposite side. Route 7 (arrowheads) is from the retromesenteric plane to the left retrorenal plane through the left fascial trifurcation and additionally into the retrocrural space; Route 8 is the contralateral pathway into the retrocrural space. Route 9 (black arrows) is the channel into the retrocrural space along the superior mesenteric artery. (B) Route 10 and Route 11 (crooked arrows) are the pathways along the left renal vein and right renal artery into the retrocrural space across the Aortic Hiatus on the left renal vein section. A: pancreas; B: superior mesenteric artery; C: inferior vena cava; D: right renal artery; E: left renal vein. (C, E) Case 1, a 34-year-old woman with recurrent acute pancreatitis. Route 5, Route 9 and Route 10 are present as fluid spreading along the left bridging septa (white arrows), superior mesenteric artery (black arrows) and left renal vein (crooked arrows) into the retrocrural space, respectively. (D) Case 2, a 47-year-old woman with recurrent acute pancreatitis. Route 6 is displayed as the fluid extending to the retrocrural space via the right bridging septa (white arrows). (F) Case 3, a 42-year-old man with recurrent acute pancreatitis. Route 11 is manifested as the fluid flowing along the right renal vein (crooked arrows) to the retrocrural space across the Aortic Hiatus.

Distribuição da artéria gástrica esquerda e artérias gástricas curtas na superfície do estômago de eqüinos e relação com a área superficial do órgão
Universidade de São Paulo, 2008Co-Authors: Luciano Da Silva Alonso, Henrique Ribeiro Alves De Resende, Marcela Vieira Duboc, Luís Cláudio Lopes Correia Da SilvaAbstract:Vessels responsible for stomach blood supply have their origin in the celyac artery, abdominal aorta first branch, in the Aortic Hiatus region. Thus, the stomach surface receives the left and right gastric arteries, the left and right gastroepiploic arteries and the breves gastric arteries. Origins of these vessels are well-known, but information about stomach surface arterial distribution are still unknown. Stomach surface blood supply has an important role on gastric mucosa defense mechanisms. Equines submitted to intensive training show high frequency of the ulcerative lesions in the gastric mucosa, with is a promising field of applicability for researches on vascularization. The aim of this study was to analyze some aspects of the stomach surface arterial distribution, of the mixed breed adults equines destined to slaughter. Equine stomachs of 15 male and 15 female were analyzed. The stomach surface area was measured with images analysis software and the data correlation with number of vessels branch accounted. A low contribution of the left gastric artery to the stomach minor curvature irrigation was observed. These results justify studies related to anatomic particularities of the region of equine stomach minor curvature, in future researches

Distribution of left gastric artery and breve gastric arteries on the surface of equine stomach and the relation to the organ´s superficial area
2008Co-Authors: Alonso, Luciano Da Silva, Henrique Ribeiro Alves De Resende, Duboc, Marcela Vieira, Luís Cláudio Lopes Correia Da SilvaAbstract:Vasos responsáveis pelo suprimento sangüíneo do estômago originam-se da artéria celíaca, primeiro ramo da aorta abdominal, localizada na região do hiato aórtico. Assim, dirigem-se à superfície do estômago as artérias gástricas esquerda e direita, as artérias gastroepilóicas esquerda e direita e as artérias gástricas curtas. Apesar de bem conhecidas as origens destes vasos, informações a respeito do comportamento dos mesmos ao atingirem a superfície do estômago ainda são escassas. O fluxo sangüíneo na parede do estômago exerce importante papel nos mecanismos de defesa da mucosa gástrica. Eqüinos em treinamento intensivo apresentam alta freqüência de ocorrência de lesões ulcerativas na mucosa do estômago, tornando as pesquisas sobre vascularização sangüínea deste órgão com grande significado prático na compreensão dos mecanismos relacionados à proteção da mucosa gástrica. O objetivo deste trabalho foi avaliar alguns aspectos relacionados à distribuição arterial na superfície do estômago de eqüinos adultos, sem raça definida e destinados a abate. Utilizaram-se estômagos oriundos de 15 machos e 15 fêmeas. A área superficial do estômago foi mensurada com software de análise de imagens e os dados correlacionados ao número de ramos avaliados. Observou-se reduzida participação da artéria gástrica esquerda na irrigação da curvatura menor do estômago. Estes achados justificam estudos relacionados à particularidades anatômicas da região da curvatura menor do estômago de eqüinos, em trabalhos futurosVessels responsible for stomach blood supply have their origin in the celyac artery, abdominal aorta first branch, in the Aortic Hiatus region.
