New approaches to abdominal aortic aneurysm rupture risk assessment - engineering insights with clinical gain

McGloughlin, Timothy M.; Doyle, Barry J. (Lippincott Williams & Wilkins, 2010)

Abdominal aortic aneurysm (AAA) rupture remains a significant cause of death in the developed world. Current treatment approaches rely heavily on the size of the aneurysm to decide on the most appropriate time for clinical ...
One-stage vs.two-stage brachio-basilic arteriovenous fistula for dialysis access: a systematic review and a meta-analysis

Bashar, Khalid; Healy, Donagh A.; Elsheikh, Sawsan; Browne, Leonard D.; Walsh, Michael T.; Clarke-Moloney, Mary; Burke, Paul E.; Kavanagh, Eamon G.; Walsh, Stewart R. (Public Library of Science, 2015)

A brachiobasilic arteriovenous fistula (BB-AVF) can provide access for haemodialysis in patients who are not eligible for a more superficial fistula. However, it is unclear whether one or two-stage BB-AVF is the best option ...
Role of far infra-red therapy in dialysis arterio-venous fistula maturation and survival: systematic review and meta-analysis

Bashar, Khalid; Healy, Donagh A.; Kheirelseid, Elrasheid A. H.; Walsh, Michael T.; Clarke-Moloney, Mary; Burke, Paul E.; Kavanagh, Eamon G.; Walsh, Stewart R. (Public Library of Science, 2014)

Introduction: A well-functioning arteriovenous fistula (AVF) is the best modality for vascular access in patients with end-stage renal disease (ESRD) requiring haemodialysis (HD). However, AVFs' main disadvantage is the ...
The role of shear stress in arteriovenous fistula maturation and failure: a systematic review

Bashar, Khalid; Griffin, Philip; Kavanagh, Eamon G.; Walsh, Stewart R.; Walsh, Michael T. (Public Library of Science, 2015)

Non-maturation and post-maturation venous stenosis are the primary causes of failure within arteriovenous fistulae (AVFs). Although the exact mechanisms triggering failure remain unclear, abnormal hemodynamic profiles ...
Rupture behaviour of abdominal aortic aneurysms: an experimental and computational investigation

Doyle, Barry J. (2009)

Abdominal aortic aneurysm (AAAs) is a permanent and irreversible dilation of the infrarenal section of the aorta. These aneurysms are typically defined as having a diameter 50% greater than the normal aortic diameter. If ...
Simulation of human atherosclerotic femoral plaque tissue: the influence of plaque material model on numerical results

Cunnane, Eoghan M.; Mulvihill, John J.E.; Barrett, Hilary E.; Walsh, Michael T. (BioMed Central, 2015)

Background: Due to the limited number of experimental studies that mechanically characterise human atherosclerotic plaque tissue from the femoral arteries, a recent trend has emerged in current literature whereby one set ...
Towards an improvement in aneurysm assessment: coupling 3D reconstruction tools with engineering know-how

Doyle, Barry J.; McGloughlin, Timothy M. (2009)

Purpose: Currently, abdominal aortic aneurysms (AAAs), which are a permanent dilation of the aorta, are treated surgically when the maximum transverse diameter surpasses 5.0cm. AAA rupture occurs when the locally acting ...
Towards the development of guidelines for the surgical treatment of carotid artery disease: a tissue characterisation approach

Mulvihill, John J.E. (University of Limerick, 2013)

Despite the proven efficacy of carotid endarterectomy (CEA), great interest has been generated in carotid angioplasty and stenting (CAS) as an alternative to CEA. The stretch caused by balloon angioplasty deployment ...
The use of silicone materials to model abdominal aortic aneurysm behaviour

Doyle, Barry J.; Callanan, Anthony; Corbett, Timothy J.; Cloonan, Aidan J.; O'Donnell, Michael R.; Vorp, David A.; McGloughlin, Timothy M. (2008)

This paper aims to identify the rupture locations of abdominal aortic aneurysms. Dow Corning Sylgard 184 was mechanically characterised. Five idealised models were then manufactured using this silicone rubber which were ...
Validity of synthetic bone as a substitute for osteoporotic cadaveric femoral heads in mechanical testing: a biomechanical study

O'Neill, F.; Condon, F.; McGloughlin, Timothy M.; Lenehan, Brian; Coffey, Calvin J.; Walsh, Michael T. (British Editorial Society of Bone and Joint Surgery, 2012)

IntroductionThe objective of this study was to determine if a synthetic bone substitute would provide results similar to bone from osteoporotic femoral heads during in vitro testing with orthopaedic implants. If the synthetic ...
Vessel asymmetry as an additional diagnostic tool in the assessment of abdominal aortic aneurysms

Doyle, Barry J.; Callanan, Anthony; Burke, Paul E.; Grace, Pierce A.; Walsh, Michael T.; Vorp, David A.; McGloughlin, Timothy M. (Elsevier, 2008)

Abdominal aortic aneurysm (AAA) rupture is believed to occur when the local mechanical stress exceeds the local mechanical strength of the wall tissue. On the basis of this hypothesis, the knowledge of the stress acting ...
Wireless measurement system for capacitive pressure sensors using strain compensated SiGeB

Arshak, Khalil; Jafer, Essa; McGloughlin, Timothy M.; Corbett, Timothy J.; Chatzandroulis, Stavros; Goustouridis, Dimitrios (IEEE Computer Society, 2007)

A prototype of miniaturized, low power, bidirectional wireless communication system was designed for in vivo pressure monitoring. The capacitive pressure sensors have been developed particularly for the medical field, where ...
