2. Diabetes Mellitus1
• Metabolic disease
• Hyperglycaemia
• Impairment of Insulin secretion, action or
both
• Chronic hyperglycaemia associated with long
term damage, dysfunction or damage of
target/ end organ i.e. BLOOD VESSELS,
NERVES, brain, eyes, kidney

3. DFU vs PAD: Overview
• Foot ulcer – common presentation
• Diagnosis
• PAD, CLI, CVI, DFU, DFI
• Referral to General Surgery / Vascular services
– Primary setting / Tertiary setting
• Treatment : Revascularization / Amputation
4. Magnitude of problem
• Diabetics Statistic
• Malaysia
– current prevalence of DM in 2015 is 17.5%, over
double since 19962
• Terengganu
– 18.6% of population (2015)3
• Financial implications
– USD 60 (2013) HSNZ KT 4 per patient (on average)

5. Diabetic Foot Ulcer
• Ulcer - break of epithelium
• Poor healing - diabetic factors
• Infection – local swelling / sepsis
• Ischaemia - element of PAD
• Classification – Wagner / Univ of Texas ,
Threatened Limb Classification (Wifl)-vascular
• Treatment – antibiotic, debridement, amputation,
Revascularization

8. Relationship of DM and PAD
• PAD 2-4 times more common in diabetics5
• 12% asymptomatic PAD in Type 1 DM and
young patients6
• 11% had PAD 6 years after DM7
• 25-28% relative risk of PAD in increased HbA1c

9. Peripheral Arterial Disease
• General term of non coronary arterial disease
• Arterial insufficiency
• Atherosclerosis
• Risk factors:
– Age: 70 years old, 50 years old (high risk eg DM)
– Male gender
– Ethnic
– Family history
– Smoking
– Hypertension
– DM
– Hyperlipidaemia
– Metabolic syndrome
11. Natural history of PAD
Asymptomatic
Intermittent claudication
Critical Limb ischaemia
Diabetes mellitus with
ulcer
12. History
• Asymptomatic – symptoms related to physical
activity or exercise
• Intermittent claudication
• Rest pain
• Non healing ulcer
• Gangrene
• + risk factors , Past Medical History
PROGRESSION
OF
DISEASE
13. • INTERMITTENT CLAUDICATION:
• Reproducible leg pain at fix distance of
walking that required patient to rest
• Distance may shortened in disease progress
• Differentiate from other causes such as
neuropathic pain, musculoskeletal pain
• Unable to get history – bedridden, pre existing
joint or muscle pain
14. Critical Limb Ischaemia
Limb at risk / threatened limb
• Rest pain – persistent, recurring ischaemic pain
required regular analgesia for more than 2 weeks
or
• Tissue Loss - leg ulceration or gangrene of the
foot or toes
With
• Ankle systolic pressure <50 mmHg or toe systolic
pressure <30mmHg
19. Hand Held doppler
• Wave form
• ABSI (Ankle/ Brachial systolic index)
• = Ankle SBP / Brachial SBP
20. ABSI INTEPRETATION
>1.1 NORMAL
HARDENED / NON COMPRESSIBLE VESSEL
0.9 – 1.1 NORMAL
0.7-0.89 MILD TO MODERATE DISEASE
(ASYMPTOMATIC TO MILD)
<0.7 MODERATE TO SEVERE DISEASE
<0.3 CRITICAL LIMB ISCHAEMIA
21. • Toe pressure examination
• Photo plethysmography
• Distal perfusion in diabetic patient
22. • Blood:
– FBC
– RBS / FBS /HbA1c
– RFT
– Lipid profile
• Wound swab for C & S
• Imaging:
– Foot X ray – osteomyelitis
– MRI foot - soft tissue infection /OM
23. Investigations
• Imaging
– Level of stenosis / occlusion
– Distal run-off
– Plan for intervention / revascularization
• Endovascular
• Open Surgery
