Abstract

It is feasible to see how communication and information technology have advanced at a rapid pace in today’s world. The introduction of wearable technology is one aspect contributing to this progress and has the potential to be an innovative solution to healthcare challenges since it may be utilized for illness prevention and maintenance, such as physical monitoring, as well as patient management. In order to solve some of the healthcare challenges, this paper proposes the development of an intelligent health monitoring system with alerts and continuous monitoring using wearable devices capable of collecting biometric data on human health. The concept was then proven by the development of a prototype using sensors connected to a micro-controller which transmits its information via MQTT to a Node-RED powered dashboard that handles the health metrics monitoring. The designed prototype has proven satisfactory to provide evidences that support the developed research questions. info:eu-repo/semantics/acceptedVersion

2. Tratamento suboclusivo por via transvenosa de fístulas arteriovenosas durais

Abstract

Introdução: As fístulas arteriovenosas durais (FAVd) são usualmente adquiridas e quando apresentam drenagem venosa cortical estão associadas a um risco elevado de hemorragia. Podem ser tratadas por embolização (transarterial ou transvenosa), cirurgicamente ou pela combinação das duas técnicas. A embolização por via transvenosa induz uma trombose iatrogénica do seio venoso, acarretando risco de enfarte venoso e/ou hemorragia. Objectivo: Rever os casos de FAVd do seio lateral submetidas a embolização transvenosa. O nosso principal objectivo é avaliar a eficácia e a morbilidade deste tipo de tratamento e o segundo é discutir as possíveis vantagens de uma abordagem suboclusiva na primeira sessão de tratamento. Resultados: Os autores apresentam seis casos clínicos de FAVd, cujas formas de apresentação foram: diminuição da acuidade visual (3); sopro pulsátil no ouvido (3); cefaleias (2); hemorragia subaracnoideia (1); hipoacusia subjectiva (1); edema da papila (1); défice motor (1). Angiograficamente: Cognard IIa (3), IIab (2) e IV (1), todas com envolvimento dos seios laterais. As principais aferências eram: ACE ipsilateral (6); ACI ipsilateral (6); AV ipsilateral (6); ACE contralateral (5); AV contralateral (5); ACI contralateral (3); ACP ipsilateral (1). O tratamento inicial foi sempre a abordagem transarterial, com resultados angiográficos aceitáveis, embora transitórios. Posteriormente optou-se pela via transvenosa com preenchimento do seio lateral com GDC coils. Em cinco dos doentes decidiu-se pela suboclusão, com persistência de algumas aferências. Em quatro, a angiografia subsequente demonstrou trombose “espontânea” do seio lateral com resolução clínica e angiográfica da doença. Num deles a trombose ocorreu ainda durante a sessão inicial. Todos os procedimentos decorreram sem complicações e nenhum dos doentes desenvolveu novos défices neurológicos focais. Conclusões: A abordagem transvenosa das FAVd obteve um sucesso técnico e clínico assinalável, sem presença de complicações. Pensamos que a suboclusão do seio venoso com coils poderá induzir menor alteração hemodinâmica aguda, possibilitando uma trombose mais lenta, diminuindo o risco de complicações, mas com resolução angiográfica ulterior da FAVd.

Abstract

Introduction: Dural arteriovenous fistulae (DAVF) are usually acquired and when presented with cortical venous drainage are associated with high risk of hemorrhage. They can be treated by arterial or venous embolization, by surgery or by the combination of both techniques. Transvenous approach induces venous sinus thrombosis increasing the risk of venous stroke and/or hemorrhage., Objective: Review of all the cases of transvenous embolization of lateral sinus arteriovenous fistulas treated in our department. Our main objective is to evaluate the clinical/imaging results of this treatment and the second goal is to discuss possible advantages of the subocclusive approach in the first session of transvenous treatment., Results: The authors present six clinical cases of DAVF with the following clinical symptoms: visual disturbances (3); ear pulsatile bruit (3); headaches (2); subarachnoid hemorrhage (1); subjective hearing loss (1); optic disc edema (1); hemiparesis (1). Angiographic classification was: Cognard IIa, (3), IIab (2) e IV (1), all of the lateral sinus. The main afferent branches arised from: ipsilateral ECA (6); ipsilateral ICA (6); ipsilateral VA (6); contralateral ECA (5); contralateral VA (5); contralateral ICA (3); ipsilateral PCA (1). Transarterial approach was the first approach in all patients with satisfactory but transient results. It was always followed by transvenous embolization of the lateral sinus with GDC coils. Subocclusive approach was achieved in five patients with the persistence of some afferent arteries. Follow-up angiography in four of them showed "spontaneous" thrombosis of the lateral sinus with clinical and angiographic cure. Thrombosis occurred once during the initial transvenous procedure. There were no complications or new neurological signs or symptoms in any patient., Conclusions: Transvenous treatment of DAVF has led to technical and clinical success without procedure complications. We think that subocclusive approach of the venous sinus with coils can cause less hemodynamic changes with a slower thrombosis rate and less complications, unchanging the angiographic and clinical resolution.
