The transverse diameter of the abdominal part of the aorta: an anatomo-radiological study through computerized tomography.

Using the computerized tomography technique in a systematic research, the authors tried to establish the most common patterns of the transverse diameter of the abdominal part of the aorta. They observed 120 cases and reached the conclusion that in both sexes the greatest transverse diameter at T11-T12 was 27 mm, at L1-L2 it was 23 mm and at L4-L5 21 mm, while the smallest diameter was 12 mm at T11-T12, 11 mm at L1-L2 and 11 mm at L4-L5. The scarcity of researches employing computerized tomography renders this contribution an important complement of anatomical and angiographic studies.

[Anatomo-radiological study of the origin of the left gastroepiploic artery]. / Estudo anátomo-radiológico da origem da artéria gastroepiplóica esquerda.

In an effort to aid the surgical procedures of the gastric-esophageal region, the authors tried to establish the most frequent anatomo-radiological patterns of the left gastroepiploic artery origin. The search consisted of thirty cases and it was possible to distinguish three fundamental types of vascular source. The absence of literature using the radiological method made this contribution very important to complete the anatomical studies.

[Anatomo-radiological study of the middle colic artery in children from 0 to 1 year]. / Contribuição para o estudo anátomo-radiológico da artéria cólicamédia em crianças de 0 a um ano.

The authors tried to establish the most frequent origin and distribution patterns of the middle colic artery. The search consisted of fifty cases and it was possible to distinguish five fundamental types of vascular origin and two basic types of distribution. The use of the radiological method for the anatomical study of small vascular structures proved us the great importance comparing it with the traditional dissecation.

Contribuicao para o estudo anatomo-radiologico da arteria colica media em criancas de 0 a um ano. / Anatomo-radiological study of the middle colic artery in childrem from 0 to 1 year

Os autores procuraram estabelecer em pesquisa sistematica, os padroes mais frequentes de origem e da distribuicao da arteria colica media. O trabalho constou de 50 observacoes e foi possivel determinarse a presenca de cinco tipos fundamentais de origem vascular e de dois tipos basicos de distribuicao. A utilizacao do metodo radiologico para o estudo anatomico de pequenas estruturas vasculares mostrou ser de grande valia em comparacao aos metodos classicos de disseccao

[Chilaiditi's syndrome]. / Síndrome de Chilaiditi.

A case of complete and permanent interposition of the intestine between the liver and diaphragm (Chilaiditi's syndrome) is reported. Although it was an accidental finding, the hepato-diaphragmatic interposition may be found in persons with gastrointestinal complaints. The diagnosis only can be done through the radiological examination and it can be differentiated between the large and small intestine interposition by a barium enema. Finally references are made by the authors about the history, pathogenesis, possible symptoms and treatment of this syndrome.

[Anatomo-radiological study of the origin of the arteria ascendens, a colic branch of the ileocolic artery]. / Contribuição para o estudo anátomo-radiológico da origem da artéria ascendens, ramo cólico da artéria íleo-cólica.

With the inadequate anatomic revision observed in the literature, the authors tried to establish the most frequent origin patterns of the arteria ascendens, colic branch of the ileocolic artery. The search consisted of one hundred cases and it was possible to distinguish four fundamental types of vascular origin. The absence of studies in radiological anatomy made this contribution very important for the knowledge of the arterial disposition in the modern diagnostic procedures of the region.

Sindrome de Chilaiditi. / Chilaiditi's syndrome

E representado um caso de interposicao hepatodiafragmatica do intestino (sindrome de Chilaiditi) do tipo completo e permanente.Apesar de ter sido um achado, a interposicao pode ocorrer geralmente acompanhada de sintomas gastrointestinais. A confirmacao diagnostica so pode ser feita atraves do exame radiologico e para se diferenciar a existencia de envolvimento do intestino delgado ou grosso deve-se utilizar o enema opaco. Finalmente sao feitas referencias aos aspectos da historia, etiopatogenia, possiveis sintomas e tratamento desta sindrome

Contribuicao para o estudo anatomo-radiologico da origem da arteria ascendens ramo colico da arteria ileo-colica. / Anatomo-radiological study of the origin of the arteria ascendens, cholic branch of the ileocholic artery

Diante da falta de uma adequada revisao anatomica, os autores procuram estabelecer em pesquisa sistematica, os padroes mais frequentes de origem da arteria ascendens, ramo colico da arteria ileo-colica. O trabalho constou de 100 observacoes e foi possivel determinar-se a presenca de 4 tipos fundamentais de origem vascular. A ausencia de trabalhos de anatomia radiologica sobre o assunto fez com que esta contribuicao se tornasse muito importante para o conhecimento da disposicao arterial nos modernos procedimentos diagnosticos desta regiao

Contribuicao ao estudo radiologico da gastrite cronica superficial. / Radiological study of chronic superficial gastritis

Os autores, utilizando o metodo radiologico de duplo contraste, estudaram as alteracoes encontradas na gastrite cronica superficial.A validade do metodo foi enfatizada, visto o grande indice de acertos no diagnostico. Correlacionaram ainda os aspectos radiologicos com a endoscopia e histologia em 31 pacientes, concluindo que o desaparecimento das pregas mucosas e o aparecimento de areas gastricas intumescidas sao de fundamental importancia para o diagnostico dos processos inflamatorios da mucosa gastrica

Some new aspects in the pathology of clubfoot.

As part of a research project that is still in progress, 12 human embryos, fetuses, and one stillborn infant with clubfeet, were given injections of barium sulfate solution with China ink for correlated-contrast radiography and anatomic dissections of cleared specimens including histologic sections. The following observations suggested a vascular factor in the etiology of congenital idiopathic clubfoot: (1) the muscular, tendinous, fascial and other soft elements were not conspicuously abnormal; (2) radiologically and anatomically, all deformed feet had vascular abnormalities consisting of an ischemic area at the level of the sinus tarsi; (3) a wedge form, with its acute angle pointed towards the head of the talus, showed the disarrangement of the vascular network at the ischemic sinus tarsi area; (4) the vascular alteration was always more conspicuous in the early period of fetal life, being reduced to a simple knot of fatty infiltration and fibrous tissue in the older specimens and in the stillborn; (5) the vascular nucleus of the talus "Anlage" also was not in the normal location in the neck, but on the deformed side of the body; (6) the established deformity was well vascularized and characterized by a small area of necrotic fatty degeneration covering the infarction area (secondary to helicoidal movement pressures of the forefoot on the hindfoot). Five stages in the fetal development of clubfoot can be defined beginning with adduction of the forefoot and ending in complete equinovarus deformity.

[Angiographic anatomy of the cecal artery]. / Anatomia angiográfica da artéria cecal.

After studying the angiographic anatomy of the cecal artery in 80 post--mortem examinations we have demonstrated the following: -The common cecal trunk (76,2% of the cases) had its origin from the right colic artery in 12 (15%) and from the ileal artery in 49 (61,2%) observations. -The anterior and posterior cecal arteries had a separate origin in 19 observations (23,7%). In 7 of these observations (8,7%) the anterior cecal artery had its origin from the right colic artery and, the posterior cecal artery originated directly from the ileal artery. In 11 observations (13,8%) both cecal arteries, originated directly from the ileal artery and, in one case (1,2%) the anterior cecal artery originated from the right colic artery and the posterior cecal artery from the ileocolic artery.

[Anatomoradiological patterns of vermiform appendix's arterial supply (author's transl)]. / Artéria apendicular: estudo anátomo-radiológico.
