Ongoing Care

Our patient exhibited a large tumor on his right upper arm where his former dialysis access site had been. X-ray, Doppler ultrasound, and magnetic resonance imaging scan could not fully reveal the nature of that tumor. Eventually, a surgical approach showed a giant aneurysm of the inflowing brachial artery to a partially obliterated arteriovenous fistula. This case highlights the importance of ongoing care for patients with arteriovenous shunts. Even arteriovenous fistulas, that are obliterated or no longer in use, can, especially when immunosuppressant therapy and other vascular risk factors are added to the overall cardiovascular risk, transform and endanger the health of our patients.

Background Vessel wall adaptation to acute or chronic flow changes is regulated by shear stress (SS) at the endothelium. This hypothesis was tested in the brachial artery (BA) of patients receiving an arteriovenous fistula (AVF) for hemodialysis vascular access. Methods The acute and sustained effects were evaluated in 13 patients. Pre-operatively and postoperatively on predetermined time-points BA diameter and shear rate (SR) were measured. SS was calculated from whole blood viscosity and SR. Analysis was performed with Wilcoxon's test and ANCOVA multivariate analysis. Results Acutely, mean SS increased (475%, p<0.05), peak-to-peak SS decreased (37%, p<0.05) and peak SS remained constant. BA diameter increased (15%, p<0.05). After one year a further increase was observed (r=0.59, p<0.001), plus an increase in mean SS (r=0.78, p<0.001). Peak-to-peak SS remained constant. Conclusion Our results indicate that after AVF placement an acute increase in SS results in an acute increase of vessel diameter. However, one year of sustained high blood flow does not result in restoration of mean SS.

Normal Ultrasound

Doppler ultrasound (DUS) is a highly sensitive and specific test for assessment of the morphology of stenoses and measure blood flow within arteriovenous fistulas (AVFs). Retrospective review of 150 Doppler studies (121 patients) performed by a single radiologist were analyzed in conjunction with contemporaneous clinical dialysis function. Volume flow in the brachial artery, peak systolic velocity (PSV), and size of the anastomosis (diameter and intimal thickness) were recorded. Volume flow in the brachial artery of ≈>1000 mL/min is a predictor of good fistula function. Volume flow in the brachial artery negatively correlates with both the reduction in perianastomotic diameter and increased intimal thickness ( P = .02) and positively correlates with increased diameter of the perianastomotic vein (PAV) ( P < .0001). Measurements of PSV across the PAV do not correlate with fistula dysfunction or a significant stenosis. Volume flow of >1000 mL/min in the brachial artery and a PAV diameter of ≥3.5 mm are predictive of a well-functioning fistula. Intimal thickening at the anastomosis can be measured on ultrasound and may be another useful parameter in the assessment of a failing fistula. These parameters could be used to exclude a significant inflow stenosis.

Introduction: CorMatrix is an acellular extracellular matrix that acts as a biological scaffold and remodels into site-specific tissue. We used it for the (re)construction of arteriovenous fistulas. Methods: In this prospective pilot case study, we used CorMatrix in six patients. We included patients who required vascular access reconstruction due to thrombosis of unsalvageable arteriovenous fistulas, patients with high-flow arteriovenous fistulas and patients with microvasculature in which autologous arteriovenous fistulas did not mature, requiring reconstruction with a graft. We sutured the CorMatrix plate into a tubular shape and then constructed arterial and venous anastomoses. Results: There were no periprocedural complications, CorMatrix-related infections, bleeding or limb swelling after the procedures. CorMatrix was first punctured after 8–10 weeks. In five patients, a percutaneous angioplasty due to CorMatrix stenosis was performed; in one patient, a stent was placed due to refractory stenosis. We observed eight thromboses during the observation period (four in one patient). Perianastomotic stenosis of CorMatrix and interdialytic hypotension were the causes of the thrombosis in five patients, cephalic arch stenosis in two patients and thromboembolism to the brachial artery and arteriovenous fistula in one patient. Thrombendarteriectomy was successful in 87.5% of patients, and one patient required arteriovenous fistula reconstruction. After a median observation period of 12.5 (range 4–23) months, all arteriovenous fistulas were patent, with a median brachial artery flow of 1450 (range 700–1700) mL/min. Conclusion: Arteriovenous fistula (re)construction with CorMatrix seems to be feasible and safe, with a relatively high incidence of neointimal hyperplasia, predominantly at venous anastomoses, but additional clinical studies are needed.
