Vascular anatomy of L1 vertebral body in Wistar rat-corrosion-fluorescence, dia...
Moura, Diogo Lino; Casal, Diogo; Alves, Sara; Pinto, Dora; Novo, Maria; Almeida, Rui; Pais, Diogo; Casanova, José; Bernardes, AntónioCopyright © 2025 AME Publishing Company. All rights reserved.; BACKGROUND: The factors influencing bone healing in complete burst fractures-key to deciding between stabilization or vertebral replacement-remain poorly defined. Arterial vascularization and bone nutrition are known to affect healing or progression to necrosis. However, the role of vascular injury in vertebral fractures is not yet conclusively demo...

Carvalho, Patrícia M.; Marguí, Eva; Kubala-Kukuś, Aldona; Banaś, Dariusz; Machado, Jorge; Casal, Diogo; Pais, Diogo; Santos, José Paulo; Pessanha, SofiaPublisher Copyright: © 2022 The Authors; Elemental content plays an important role in biological processes, and so, the multielemental analysis of human tissue samples is required in biomedical research. Still, the small amount of available biological samples and the adipose content of the samples can be major setbacks for the accurate determination of elemental content. In this study, we explored the potential...

P6 CFD Modelling of Arterialized Venous Flap
Serrano, Andreia de Jesus Grilo; Casal, Diogo; O'Neill, João Goyri; Vassilenko, ValentinaThe knowledge about the required quantity of blood to irrigate an angiosome is important on ischemia (disruption on blood perfusion) prediction, diagnosis and treatment. An angiosome (or flap) is an anatomic unity (or flap) of tissue, it is constituted by skin, subcutaneous tissue and muscle, it is irrigated by an artery and drain by specific veins [1]. Since 70’s, flaps have been used on clinical practice for ...
The use of free fibula-flexor hallucis longus osteomuscular flap for calcaneal ...
Mata-Ribeiro, Luís; Casal, Diogo; Ferreira, João Amaral; Costa, Daniel Sá; Lacerda, JoãoINTRODUCTION: Calcaneal osteomyelitis poses a tough challenge for any reconstructive surgeon. The eradication of the infection and the reconstruction of the defect are the main goals of treatment. PRESENTATION OF CASE: We present the case of a 53-year-old male with chronic calcaneal osteomyelitis. The patient was submitted to several bone and soft tissue debridements and twice the application of gentamicin/sulf...
BD-2 and BD-3 increase skin flap survival in a model of ischemia and Pseudomona...
Casal, Diogo; Iria, Inês; Ramalho, José S.; Alves, Sara; Mota-Silva, Eduarda; Mascarenhas-Lemos, Luís; Pontinha, Carlos; Guadalupe-Cabral, MariaThe main aim of this work was to study the usefulness of human β-defensins 2 (BD-2) and 3 (BD-3), which are part of the innate immune system, in the treatment of infected ischemic skin flaps. We investigated the effect of transducing rat ischemic skin flaps with lentiviral vectors encoding human BD-2, BD-3, or both BD-2 and BD-3, to increase flap survival in the context of a P. aeruginosa infection associated w...

Ribeiro, Fernando Silva; Bettencourt Pires, Maria Alexandre; Silva Junior, Edivaldo Xavier; Casal, Diogo; Casanova-Martinez, Daniel; Pais, DiogoINTRODUCTION: The aim of the present study is to report an original, unusual, case of bilateral anatomical variation of the sciatic nerve, with low origin and high division. MATERIAL AND METHODS: Anatomical dissection was performed on a 66 year-old female cadaver. The corpse was embalmed and conserved through our original embalming techniques. RESULTS: The particular anatomical variation was first detected duri...
