Abstract
Leg compression bandaging is the mainstay of venous ulcer treatment, yet little is known about the impact of therapeutic compression levels on arterial haemodynamics. In this study, the effect of foot-to-knee, four-layer compression bandaging on below-knee arterial pulsatile blood flow was assessed by nuclear magnetic resonance flowmetry.

Whatever the mechanism(s), the finding of a compression-associated pulsatile flow increase suggests an arterial linkage, which may play a role in the well-documented beneficial effects of compression bandaging in venous ulcer and lymphedema treatment. Possible beneficial effects of the arterial flow-pulse increase on venous ulcer outcome may be related to a decrease in leukocyte effects in the distal microvasculature.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Mayrovitz</LastName><ForeName>H N</ForeName><Initials>HN</Initials><AffiliationInfo><Affiliation>Nova Southeastern University, College of Medical Sciences, Ft Lauderdale, FL 33328, USA. mayrovit@nova.edu</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Macdonald</LastName><ForeName>J M</ForeName><Initials>JM</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>Italy</Country><MedlineTA>Int Angiol</MedlineTA><NlmUniqueID>8402693</NlmUniqueID><ISSNLinking>0392-9590</ISSNLinking></MedlineJournalInfo><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName UI="D000328" MajorTopicYN="N">Adult</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D001158" MajorTopicYN="N">Arteries</DescriptorName><QualifierName UI="Q000502" MajorTopicYN="N">physiology</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D001783" MajorTopicYN="N">Blood Flow Velocity</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D058128" MajorTopicYN="Y">Compression Bandages</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D005260" MajorTopicYN="N">Female</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D006801" MajorTopicYN="N">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D007866" MajorTopicYN="N">Leg</DescriptorName><QualifierName UI="Q000098" MajorTopicYN="Y">blood supply</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D009682" MajorTopicYN="N">Magnetic Resonance Spectroscopy</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D008297" MajorTopicYN="N">Male</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D008875" MajorTopicYN="N">Middle Aged</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D011312" MajorTopicYN="N">Pressure</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D011673" MajorTopicYN="Y">Pulsatile Flow</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D012039" MajorTopicYN="N">Regional Blood Flow</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D012212" MajorTopicYN="N">Rheology</DescriptorName><QualifierName UI="Q000379" MajorTopicYN="N">methods</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D016683" MajorTopicYN="N">Supine Position</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D014160" MajorTopicYN="N">Transducers, Pressure</DescriptorName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="entrez"><Year>2010</Year><Month>10</Month><Day>7</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2010</Year><Month>10</Month><Day>7</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2011</Year><Month>2</Month><Day>1</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">20924348</ArticleId><ArticleId IdType="pii">R34102555</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
