CH 10: Hemodialysis Access

The radial artery and cephalic vein

A Brescia-Cimino fistula is created by the anastomosis of which two vessels?

Use a fast sweep speed

In order to improve accuracy of flow volume measurements, which of the following is NOT true?

900 mL/min—2500 mL/min

What is a normal flow volume in a mature, well-functioning brachial-cephalic AVF?

Low resistive

What flow pattern is excepted for arterial inflow of an AVF/AVG?

inflow artery, distal to the anastomosis

When interrogating for steal syndrome in a fistula, where should the sample volume be placed?

Basilic vein transposition

What dialysis access configuration may be complicated by swing point stenosis?

Brachial-cephliac

A higher incidence of cephalic arch stenosis is seen in this type of dialysis access:

Brachial pressure difference (>20 mmHg) between the arms

When performing preoperative mapping for dialysis access, adequate arterial inflow is indicated by all of the following except:

It does not require maturation, can be used sooner

Which of the following is an advantage of an arteriovenous graft (AVG) over an arteriovenous fistula (AVF).

< 0.7

A resistive index of _____ indicates a normal response to flow-meditated dilation in the brachial artery induced by opening a fist that has been clenched for 2 minutes.

Brachial-axiallry straight AVG

The venous anastomosis is a frequent site of stenosis in this dialysis access configuration:

Can be cannulated easily

Brachial-cephalic fistulas are preferred upper arm access because they:

Hand ischemia

This complication is seen in fistulas with a wide arterial anastomosis:
