Haemodialysis arteriovenous access—a prospective haemodynamic evaluation

Abstract: This study shows that at least in the short term following the creation of a dialysis a-v access, a mild state of volume overload develops, which is offset by the ¿unloading' effect of the decreased peripheral vascular resistance; the latter is probably mediated by secretion of ANP in response to atrial stretching.

“…LVH has been described to correlate with the size of AV fistula. In some clinical studies, creation of AV fistulas worsened LVH [17], while other studies did not confirm this data [18,19]. The actual effects on LVH in patients with underlying resistant hypertension have yet to be studied.…”

“…While the ROX Coupler creates a fixed but modifiable shunt size, hemodialysis fistulae do gradually increase the amount of shunted blood due to ongoing dilation. Formation of an AV fistula or graft in patients with ESRD decreased SVR in average by 23.5 % (p<0.02) [22] and 17 % (p<0.01) [17].…”

“…Os pacientes submetidos a DAPE mantém padrão hemodinâmico similar aos controles normais. Da mesma forma, observa-se caracteristicamente a normalização do débito cardíaco após o fechamento de fístulas arteriovenosas 52,29,53 .…”

“…Evidentemente, o tempo para instalação das alterações funcionais depende tanto da reserva funcional do miocárdio quanto da intensidade do fluxo pela fístula 29,54 . Desta forma, se o aumento do retorno venoso for gradativo, como em portadores de insuficiência renal crônica submetidos a hemodiálise através de fístulas arteriovenosas 53 , ou mantiver-se estável ao longo do tempo, os mecanismos cardiovasculares compensatórios proporcionarão condições adequadas para acomodação deste volume adicional, mantendo a função sistólica adequada as custas de dilatação da cavidade ventricular esquerda 29 .…”
