“…In support of this persisting deficiency in vasomotor function over time, Buturak and colleagues 32 found both FMD and NMD to be significantly reduced from baseline at 6 months post-TR procedure. In contrast, although Dawson et al 29 also reported an early impairment in FMD and NMD following RA-CA, these authors found that endothelial and smooth muscle vaso- …”

Does Previous Transradial Catheterization Preclude Use of the Radial Artery as a Conduit in Coronary Artery Bypass Surgery?

AbstrAct:The radial artery (RA) is a commonly used conduit for coronary artery bypass grafting, and recent studies have demonstrated that it provides superior long-term patency rates to the saphenous vein in most situations. In addition, the RA is also being used with increasing frequency as the access point for coronary angiography and percutaneous coronary interventions. However, there has been concern for many years that these transradial procedures may have a detrimental impact on the function of RA grafts used in coronary artery bypass grafting, and there is now comprehensive evidence that such interventions cause morphologic and functional damage to the artery in situ. Despite this, there remain remarkably few studies investigating the use of previously cannulated RAs as grafts in coronary artery bypass surgery, and there are no clear guidelines on the use of the RA in coronary artery bypass grafting after its catheterization. This article will review concisely the evidence that transradial procedures cause damage to the RA, and discuss the impact this could have on previously cannulated RAs used as coronary artery bypass grafting conduits. On the basis of the evidence assessed, we make a number of recommendations to both surgeons and cardiologists regarding use of the RA in cardiovascular procedures.

“…The duration of this damage, however, is less clear; although a number of studies have demonstrated recovery of the RA with time, 29,36 others have shown a progressive deterioration in function. 28,30 Additional studies investigating the long-term impact of TR procedures on RA function are therefore warranted.…”

“…7 After assessment and analysis of the L-FMC and FMD data, L-FMC+FMD was calculated as the sum of L-FMC and FMD. We have previously reported the impact of radial catheterization on FMD in patients included in study 1,6,7 who are nonetheless included here to assess the impact of catheterization on L-FMC and combined L-FMC+FMD.…”

“…Due to the relatively small diameter of this artery, catheter sheath insertion is associated with endothelial denudation and impairment in endotheliumdependent FMD. [6][7][8][9] Although previous studies have assumed that L-FMC of the radial artery is endothelium-mediated, none, to our knowledge, has examined whether radial artery L-FMC is directly affected by arterial catheterization.…”

The aim of this study was therefore 2-fold: to examine the impact of catheterization on radial artery vasoconstrictor function (L-FMC) in the catheterized (Cath) and noncatheterized arms, and to examine the impact of localized handgrip exercise training on radial artery FMD and L-FMC after catheterization. We hypothesized that L-FMC would be Background-Radial artery catheterization is associated with endothelial denudation and impaired vasodilator function, while postcatheterization exercise training may enhance artery function. The impact of catheterization and subsequent exercise training on low-flow mediated vasoconstriction (L-FMC) has not previously been studied. The aim of this study was to examine whether radial artery L-FMC is impaired by catheterization and consequent endothelial denudation. A further aim was to examine the effect of local handgrip exercise training on radial artery L-FMC and flow-mediated dilation (FMD) after transradial catheterization. Methods and Results-Thirty-two subjects undergoing transradial catheterization underwent assessment of L-FMC and FMD in the catheterized and contralateral radial artery before, and the day after, catheterization. A further 18 patients were recruited and randomly assigned to either a 6-week handgrip exercise training program (N=9)

“…However, while these coatings have proven effective at reducing the incidence of spasm and improving patient comfort, the use of hydrophilic sheaths does not appear to prevent the reduction in flow mediated dilation, an index of endothelial dysfunction [9], and did not markedly influence the incidence of radial occlusion [10,11]. Further, the use of certain hydrophilic coatings (for example, those manufactured by Cook [12,13]) has been associated with the formation of sterile granulomas and abscesses [14][15][16][17][18].…”

The friction behaviour of new chitosan derivative coatings obtained by chemical modification of chitosan with fatty acids (linoleic and dilinoleic acid) has been investigated in order to explore their potential as endovascular catheter coatings and to benchmark them against commercially available coatings used in endovascular catheter applications. An in vitro tribological system was developed that was intended to represent to a limited extent the in vivo tribological conditions of a typical endovascular catheterization procedure. Continuous reciprocating sliding tests were carried out with uncoated and coated polymer specimens. The results showed that all of the coatings tested decreased the coefficient of friction compared to the uncoated polymer. Compared to a neat chitosan coating, the chitosan derivative coatings showed a clear reduction in the coefficient of friction to levels similar to those of the commercially-available coatings. A comparison between the friction results and contact angle measurements carried out on the coatings indicated that a range of contact angle values exists for which the friction coefficient is at a minimum. The reason for this is unclear and further studies are required in order to confirm and investigate the trend, especially within the context of hydrophilic lubricious coating development.
