Evaluation of inter- and intra-operator variability in a pulse wave velocity as...
Costa, Ana; Silva, Ana; Fernandes, Filipe; Cunha, Gilda; Fonseca, Virgínia; Lobato, João; Vassilenko, Valentina; Goyri-O'Neill, JoãoBackground – Pulsed wave velocity (PWV) assessment devices are valuable instruments for the determination of the cardiovascular risk of each individual. PWV is one of the existing parameters in the guidelines for the management of hypertension. It’s important to evaluate inter and intra-operator variability so the devices can increase their value. This study aims to classify inter and intra-operator variability...
New Paths for Anatomy

Improvement of the Embalming Perfusion Method: The Innovation and the Results b...
Goyri-O'Neill, João; Pais, Diogo; Freire de Andrade, Francisco; Ribeiro, Paulo; Belo, Ana; O'Neill, Assunção; Ramos, Samuel; Neves Marques, CláudiaEmbalming is a chemical process that aims the preservation and sanitization of the human body indefinitely. The technique of embalm­ing is an important tool in teaching and research in anatomy enabling the preservation of cadaveric material in good conditions (lessen­ing any significant structural changes and maintaining the natural appearance). This article presents the results of embalmed cadavers in ...
Sciatic Nerve High Division: Two Different Anatomical Variants
Pais, Diogo; Casal, Diogo; Bettencourt Pires, Maria Alexandre; Furtado, Andrea; Bilhim, Tiago; Angélica-Almeida, Maria; Goyri-O'Neill, JoãoIntroduction: Sciatic nerve variations are relatively common. These variations are often very significant in several fields of Medicine. The purpose of this paper is to present two such variants and discuss their clinical implications.Material and Methods: Three Caucasian cadavers with no prior history of lower limb trauma or surgery were dissected and found to present anatomical variants of the sciatic nerve.R...
Radiologic Anatomy of Arteriogenic Erectile Dysfunction: A Systematized Approach
Pereira, José António; Bilhim, Tiago; Rio Tinto, Hugo; Fernandes, Lúcia; Martins Pisco, João; Goyri-O'Neill, JoãoIntroduction: Erectile Dysfunction is a highly prevalent disease and there is growing interest in its endovascular treatment. Due to the complexity of the male pelvic arterial system, thorough anatomical knowledge is paramount. We evaluated the applicability of the Yamaki classification with Computerized Tomography Angiography and Digital Subtraction Angiography in the evaluation of patients with arteriogenic E...
Vertebral Metrics: Application of a New Mechanical Instrument to Evaluate the S...
Quaresma, Cláudia; Dias, Inês; Forjaz Secca, Mário; Goyri-O'Neill, João; Branco, JorgeObjective: To present the results of the first application of the new technology - Vertebral Metrics - the analysis of the 3D position of the vertex of each spinous process in pregnant women.Material and Methods: The Vertebral Metrics was applied to women without associated pathology in four stages of pregnancy (12, 20, 32, 37 weeks gestation). We applied univariate linear models.Results: We found that the diff...
Brachial Plexus Morphology and Vascular Supply in the Wistar Rat
Angélica-Almeida, Maria; Casal, Diogo; Mafra, Manuela; Mascarenhas-Lemos, Luís; Martins-Ferreira, José; Ferraz-Oliveira, Mário; Amarante, JoséIntroduction: The rat is probably the animal species most widely used in experimental studies on nerve repair. The aim of this work was to contribute to a better understanding of the morphology and blood supply of the rat brachial plexus.Material and Methods: Thirty adult rats were studied regarding brachial plexus morphology and blood supply. Intravascular injection and dissection under an operating microscope...
Giant Cysts of Seminal Vesicles
Furtado, Andrea; Ferrito, Fernando; Goyri-O'Neill, JoãoWe report a clinical case of a 60 year-old man, asymptomatic to whom was incidentally found two retrovesical cysts. Physical examination revealed hypogastric, elastic and painless masses; digital rectal examination documented a normal prostate gland. Computerized tomography confirmed the presence of two giant seminal vesicle cysts.; Relatamos o caso de um homem com 60 anos de idade, assintomático que é referenc...
An Unusual Variety of the Extensor Digiti Muscles: Report with Notes on Repetit...
Bettencourt Pires, Maria Alexandre; Casal, Diogo; Mascarenhas de Lemos, Luís; Godinho, Carlos Eduardo; Pais, Diogo; Goyri-O'Neill, JoãoIn over 500 human cadaveric dissections of arms and forearms, performed to the present date, we find frequent anatomical variations, corresponding to classic descriptions. Last year, we found a singular anatomic variation of the extensor muscles of the forearm, which seems previously undescribed. It is our strong belief that gross anatomy studies, and gross dissection should be updated and reintroduced in moder...
The Relic in the Panels of São Vicente de Fora
Goyri-O'Neill, João; Camisão-Soares, Artur; Neves Marques, CláudiaThe Panels of São Vicente de Fora, a polyptych dated from 1470 to 1480, are a work composed of 6 panels, authored by Nuno Gonçalves, a painter of King Afonso V. This work reveals one of the most remarkable collective portraits of European painting, making this polyptych an inexhaustible source of readings and interpretations, fueling a secular controversy. The present work aims analyzing precise an iconographic...
