Brachial Plexus Morphology and Vascular Supply in the Wistar Rat
Almeida, MA; Casal, D; Mafra, M; Mascarenhas-Lemos, L; Martins-Ferreira, J; Ferraz-Oliveira, M; Amarante, J; Goyri-O'Neill, JIntroduction: 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 microsc...
Sciatic Nerve High Division: Two Different Anatomical Variants
Pais, D; Casal, D; Bettencourt Pires, MA; Furtado, A; Bilhim, T; Almeida, MA; Goyri-O'Neill, JIntroduction: 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 ...
Defying Standard Criteria for Digital Replantation: A Case Series
Casal, D; Gomez, MM; Antunes, P; Candeias, H; Almeida, MAINTRODUCTION: There is much controversy regarding the current indications and contraindications for digital replantation. PRESENTATION OF CASE: Three patients with absolute contraindications for digital replantation according to classical criteria are presented (Case 1: multilevel amputation of the hand and fingers; Case 3: avulsion of the thumb; Case 4: index amputation proximal to the insertion of the flexor...
Necrosis of a Guinea Pig Stomach after Contact with Povidone-Iodine: a Case Report
Silva, J; Barata, P; Casal, D; O'Neill, A; Alves, P; O'Neill, JRodents are the most frequently used animals in surgical experimentation. It is estimated that guinea pigs in particular are the third most commonly used species in this context. To disinfect guinea pigs’ skin, either alcohol or surgical iodine are most often used. In the context of an animal research project, a Nissen operation was performed in an adult male guinea pig. Because of accidental contamination of t...
Neurogenic Thoracic Outlet Syndrome Associated with Cervical Rib
Millan, G; Casal, D; Sagaribay, A; Marques, V; Estrela Martins, JA true neurogenic thoracic outlet syndrome (TOS) associated with a cervical rib is considered extremely rare. The authors present their experience with 5 cases of true neurogenic TOS associated with a cervical rib. All patients were female and had a cervical rib confirmed radiographically pre-operatively. Average age was 34,8 years. Although all patients had been treated with several combinations of diverse dru...

Bilhim, T; Pisco, JM; Rio Tinto, H; Fernandes, L; Pinheiro, LC; Furtado, A; Casal, D; Duarte, M; Pereira, J; Oliveira, A; Goyri-O'Neill, JPURPOSE: To describe the anatomy and imaging findings of the prostatic arteries (PAs) on multirow-detector pelvic computed tomographic (CT) angiography and digital subtraction angiography (DSA) before embolization for symptomatic benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: In a retrospective study from May 2010 to June 2011, 75 men (150 pelvic sides) underwent pelvic CT angiography and selective...
Abdominoplasty and Thoraco-Epigastric Flaps for Large Anterior Trunk Defects af...
Casal, D; Fradinho, N; Ramos, L; Ferreira, J; Varanda, A; Diogo, C; Baltazar, J; Fernandes, M; Correia, C; Almeida, MAINTRODUCTION: Excision of large dermatofibrosarcoma protuberans in the anterior aspect of the trunk often results in large surgical defects that frequently dictate the need for microsurgical reconstruction. However, this option is not always available. PRESENTATION OF CASE: The authors describe two patients with very large anterior trunk dermatofibrosarcoma protuberans: one in the epigastric region and the oth...
A Rare Variant of the Ulnar Artery with Important Clinical Implications: a Case...
Casal, D; Pais, D; Toscano, T; Bilhim, T; Rodrigues, L; Figueiredo, I; Aradio, S; Almeida, MA; Goyri-O'Neill, JBACKGROUND: Variations in the major arteries of the upper limb are estimated to be present in up to one fifth of people, and may have significant clinical implications. CASE PRESENTATION: During routine cadaveric dissection of a 69-year-old fresh female cadaver, a superficial brachioulnar artery with an aberrant path was found bilaterally. The superficial brachioulnar artery originated at midarm level from the...
A 63-Year-Old Woman Presenting with a Synovial Sarcoma of the Hand: a Case Report
Casal, D; Ribeiro, AI; Mafra, M; Azeda, C; Mavioso, C; Mendes, MM; Mouzinho, MMINTRODUCTION: Synovial sarcoma is a high-grade, soft-tissue sarcoma that most frequently is located in the vicinity of joints, tendons or bursae, although it can also be found in extra-articular locations. Most patients with synovial sarcoma of the hand are young and have a poor prognosis, as these tumors are locally aggressive and are associated with a relatively high metastasis rate. According to the literatu...
Reconstruction of Large Defect of Foot with Extensive Bone Loss Exclusively Usi...
Gomez, MM; Casal, DIn cases of extensive damage to the foot, with significant bone loss, it is generally accepted that reconstruction must include bone flaps or grafts either in the emergency setting or subsequently. In this report, we describe the case of an 18-year-old student with an avulsion injury of the dorsum of his right foot. Consequently, he lost most of the soft tissue over the dorsum of the foot and the cuboid, navicu...
