Vascular cryografts offer better biomechanical properties in chronically hemodialyzed patients: Role of cryograft type, arterial pathway, and diabetic nephropathy as matching determinants: Thoughts and progress
This study aimed to characterize the following: (i) in chronically hemodialyzed subjects (CHDSs), with and without diabetic nephropathy (DN), and in healthy subjects (non-CHDSs) different arterial pathways stiffness to determine potential pathology-dependent, etiology- and/or pathway-dependent diffe...

The arterial pathways regional differences and the subjects' arterial pathways-substitutes BM were calculated. Arterial stiffness levels and regional differences were higher in CHDS than in non-CHDS. Among CHDS, those with DN showed higher stiffness in the aorto-femoral pathway and larger regional differences. Cryografts showed always the least BM. Non-CHDS and CHDS differed in the cryograft of election. In CHDS, the BM was related with the cryograft type, arterial pathway, and renal disease etiology. The BM could be minimized, selecting the most adequate cryograft type, taking into account the recipient specific characteristic (i.e., arterial pathway and renal disease etiology). © 2010, International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc. 2010 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_0160564X_v34_n8_p677_Zocalo http://hdl.handle.net/20.500.12110/paper_0160564X_v34_n8_p677_Zocalo |
