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.

Pathophysiologic Mechanisms

Aneurysmal arterial dilatation is an infrequent complication following arteriovenous fistula ligation. Herein, we are describing a case in which a 49-year-old transplanted patient developed a true, symptomatic, brachial artery aneurysm 25 years after transplantation and 12 years after ligation of his radiocephalic wrist fistula. Treating strategy included aneurysmectomy and reversed vein interposition using ipsilateral, dilated branch of cephalic vein. Two years postoperatively, the patient remains without complications. Moreover, we mention the pathophysiologic mechanisms that may have contributed to this phenomenon.

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.
