Flashcards in Penile non-imaging and imaging Deck (10):
1

limitations:

a) High level of anxiety or antagonism
b) duplex needed for velocities and anatomic conditions
c) sensitivity to injectable medication

2

ABI calculated for penile arterial evaluation?

poor arterial inflow to LE due to prox obstruction may affect penile arterial flow.

3

Technique for penile pressures

Obtained with Doppler or PPG
Probe placement: lateral or ventral
Cuff size 2.5 cm x 12.5cm

4

Penile/brachial index

Normal = > 0.75
marginal = 0.65-0.74
abnormal=

5

Reduced pressures is highly suggestive of what level disease?

proximal arterial disease
aorta-iliac; internal iliac arteries

6

In penile imaging, prior to injection of medication what arteries are measured in trans?

cavernous (cavernosal) arteries

7

Where is medication injected into the penis to induce erection?

lateral aspect, proximal shaft

8

1-2 minutes post-injection, the same measurements of the cavernous arteries are obtained. When normal should the arteries increase or decrease post-injection?

increase
PSV should increase. 30 cm/sec or higher are normal

9

The velocity of what veins are measured?

dorsal

10

Dorsal vein velocities should not increase, an increase could suggest what?

venous leak
normal = 20 cm/sec
