Arterial Wounds

Arterial wounds are frequently caused by

PAD

LE wound with PAD is defined as

Critical Limb Ischemia (CLI)

reduction is distal limb perfusion below resting metabolic requirements

Causes of poor perfusion

vasculitis

kidney disease

HTN

increase age

trauma

CAI

Arteriosclerosis

thromboangitis obliterans

Systemic presentation **

severe LE pain

cold feet, extremities

hairless

easily injuries

cracks/fissures on heels

thickened toenails

intermittent claudication (severe muscular pain)

severe pain (require dependent position)

erythema

redness of the skin, caused by dilated capillaries

Arterial wounds usually look like what ?where?

dorsal foot, distal toes, ice cream scoop, painful, periwound , diminished pulse

Dx testing for Arterial Wounds

Ankle Brachial Indea

Toe brachial Index (TBI)

transcutaneous O2 pressure (TcPO2)

Normal Value for Ankle Brachial Index

0.9-1.0

1.1-1.2 still normal

under BLANK is severe arterial disease TBI value?

<0.5 is severe arterial disease

Toe Brachial index normal value

>0.75

Performed when the ABI is abnormally high (>1.3) d/t calcification?

Toe brachial index

Transcutaneous Oxygen pressure Normal?

>50 mmHg

good wound healing potential: >40 mmHg

good indicator of level of amputation***

use BLANK for dorsalis pedis

doppler ultrasound

capillary refill is?

>3 seconds is abnormal

in supine, elevate LE to BLANK degrees

60 degrees

normal venous filling time

15 seconds
