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.

[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.

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 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

Radiological routine examination of the stomach and duodenum by means of double contrast method.

The double contrast radiologic examination performed routinely allows us to improve the study of the mucosal relief, thus increasing the diagnosis of gastric ulcers, polyps and gastric cancer. In the operated stomach one can obtain better results with this technique than with the conventional examinations.

[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.

The authors tried to establish the most frequents anatomo-radiological patterns of the irrigation on the vermiform appendix. The search was done in one hundred cases they found six different patterns of arterial irrigation.
