Impact Of Open And Endovascular Caseload In Lower Limb Amputation In Portugal –...
Jácome, Filipa; Freitas, Alberto; Sampaio, Sérgio; Dias-Neto, Marina; Castro-Ferreira, RicardoObjectives: Effective revascularization is the cornerstone of limb salvage in chronic limb threatening ischemia. In recent years, less invasive endovascular revascularization techniques have supplanted surgical bypass as the primary mode of revascularization. The real impact of this transition is being increasingly questioned. This study aims to evaluate the endovascular evolution, and how it impacted the amput...
Preoperative Embolization Of Carotid Body Tumours: Yes Or No?
Soares, Tiago; Dias, Paulo; Sampaio, Sérgio; Teixeira, JoséIntroduction: Carotid body tumours (CBT) are rare paragangliomas for which surgical resection is still the recommended treatment. Frequently they are a benign disorder, discovered as asymptomatic neck masses located at the carotid bifurcation. Preoperative embolization has been used to decrease tumor volume, intraoperative blood loss and nerve injuries.There is however still much controversy and some studies ar...
CATHETER DIRECT THROMBOLYSIS IN ACUTE LOWER LIMB ISCHAEMIA IN DIFFERENT AETIOLO...
Soares, Tiago; Dias, Paulo; Sampaio, Sérgio; Teixeira, JoséIntroduction: Over the past few decades management options of the acute limb ischaemia (ALI) have changed. Nowadays, catheter direct thrombolysis (CDT) is commonly used as an alternative to surgery in immediate management of the ALI and may offer certain advantages over surgery in appropriately selected patients. Objective: To evaluate CDT data for the treatment of acute ischaemia in lower extremity in differen...

Soares, Tiago; Dias, Paulo; Sampaio, Sérgio; Teixeira, JoséINTRODUÇÃO: A doença cística da adventícia é uma condição vascular rara e que afeta na maioria dos casos a artéria poplítea. Habitualmente cursa com claudicação intermitente durante o exercício. CASO CLÍNICO: Descreve-se um caso clínico de uma doente com doença cística da adventícia da artéria poplítea. A apresentação clínica foi sob a forma de claudicação intermitente gemelar direita. ...
NEW CONCEPTS IN ADIPOSE TISSUE AND ABDOMINAL AORTIC PATHOLOGY
Dias-Neto, Marina; Nunes, Fábio; Almeida, Glória; Ramos, José Fernando; Teixeira, José Fernando; Sampaio, Sérgio; Leite-Moreira, AdelinoPerivascular adipose tissue has been increasingly recognized as an important producer of vasoactive factors and cytokines that may have a direct paracrine effect on the vasculature due to the inherent proximity. In this regard, perivascular adipose tissue-vessel interaction might be identified as a novel therapeutic target of vascular diseases. Conversely to other specific adipose depots, whose characteristics ...
EPIDEMIOLOGICAL TRANSITION IN ABDOMINAL AORTIC ANEURYSM
Dias-Neto, Marina; Ramos, José Fernando; Sampaio, Sérgio; Freitas, AlbertoAbdominal aortic aneurysm (AAA) has shown an epidemiological transition in Western countries. The standard of the XX century characterized by increasing incidence and mortality has been replaced by decreasing incidence and mortality due to AAA. The decrease in deaths from AAA observed since the 90s seems to have been motivated by reduced exposure to risk factors, increased use of cardioprotective drugs, increas...
RISKS FACTORS FOR AORTIC CALCIFICATION AND IMPACT OF NECK AND ANEURYSM SAC CALC...
Oliveira-Pinto, José; Rocha-Neves, João; Sousa, Joel; Sampaio, Sérgio; Mansilha, ArmandoAneurysm sac shrinkage represents an important determinant of absence of early complications after EVAR. However, it occurs in about 60% of patients. Proximal neck and aneurysm sac calcification seem to constitute risk factors for absence of shrinkage, however its real impact is still under intense debate. Besides, despite well described risk factors for aortic calcification, data regarding its influence in the...
PREOPERATIVE MORTALITY SCORES IN RUPTURED ANEURYSMS — BIBLIOGRAPHIC REVIEW
Oliveira-Pinto, José; Carneiro, Inês; Sousa, Joel; Sampaio, Sérgio; Mansilha, ArmandoRuptured Abdominal Aortic Aneurysms present with significant lethality, long hospitalization periods at intensive care units and elevated health costs. Aneurysm-related mortality is highly dependent on the clinical state and physiological reserve of the patient previous to the surgery. In order to stratify which factors may condition mortality and to understand the best candidates for surgical treatment, severa...
MINHO robot football team for 2001
Ribeiro, A. Fernando; Machado, Carlos; Sampaio, Sérgio; Martins, BrunoThis paper describes an autonomous robot football team. The work is being carried out since 1998. It describes the hardware used by the robots, the sensory system and interfaces, as well as the game strategy. Data acquisition for the perception level is carried out by the vision system, and the image processing system is described. Two cameras are used requiring sensorial fu-sion. With this architecture, an att...
Minho robot football team
Machado, Carlos; Sampaio, Sérgio; Martins, Bruno; Ribeiro, A. FernandoResearch and development in the robotics field can be greatly improved by attracting people with different challenges. RoboCup consists of a new challenge in which a team of robot players are supposed to play football with similar rules to the human football. This paper describes an Autonomous Mobile Robot Minho team solution. The robots were designed and developed by a group of undergraduate students from the ...
