1 Peripheral Arterial Disease :PAD

2 Introduction PAD caused by atherosclerotic occlusion of arteries to legs Prevalence 12% and increases to 20% if persons older than 70 yr. Affects men and women equally pt. with PAD, even absence of Hx of MI or ischemic stroke have same relative risk of death from CVS cause as pt. with Hx of CAD or CVD

3 Introduction Rate of death of all causes equal in men and women and is elevated even in asymptomatic pt. Severity of PAD is closely associated with risk of MI, ischemic stroke, and death from vascular cause Lower ABI – greater risk of CVS events Critical leg ischemia – mortality of 25%

4 RISK FACTOR  Smoking  DM  HT  Hypercholesterolemia

5 Normal Artery and Artery With Plaque Buildup

6 PAD in THAILAND  Male 4%  Female 8%  Risk Factor  Age  DM > 12 yrs  HT

7 A Life Threatening Condition  The REACH (Reduction of Atherothrombosis for Continued Health) Registry has expanded mortality associated with PAD  At one year, 19% of the PAD population had experienced either an MI, a stroke or were hospitalised for an atherothrombotic event or had died from CV causes compared to 10% of the CAD population and 7% of CVD population.

8 PAD vs DM  DM ทำให้เพิ่มความชุกของ PAD 2 เท่า  1.5% ของผู้ป่วย DM จะถูกตัดนิ้ว ขา  50% จะถูกตัดเพิ่ม  50% ถูกตัดอีกข้าง ภายใน 2 ปี  50% ที่ถูกตัดขา เสียชีวิต ภายใน 5 ปี

9 Clinical Staging of LEAD

10

11 Screening for PAD  ABI  Selection of patient high risk  DM  Age 50 years.

12

13 Ankle-Brachial Index (ABI)

14 INTERPRETATION  NORMAL  MILD  MODERATE  SEVERE < 0.4  POORLY COMPRESSIBLE > 1.3

15 TREATMENT  งดสูบบุหรี่  ออกกำลังกาย  ควบคุม ความดัน (140/90 mmHg)  LDH < 100  Medication  Endovascular treatment  Surgery

16

17 การประเมินผู้ป่วยที่มีอาการ Claudication ผู้ป่วยที่มีอาการแบบ classic claudication ตรวจร่างกายระบบหลอดเลือด ตรวจ resting ankle - brachial index (resting ABI) ABI ≤ 0.90 ABI > Exercise ABI - Toe-brachial index - Segmental pressure measurement - Duplex ultrasound exam. Confirmation of PAD diagnosis Abnormal results Normal results No PAD or consider arterial entrapment syndrome - Risk factors normalization - Pharmacological risk การรักษาภาวะ claudication

19 Intervention of PAD

20 Toe gangrene in a patient with diabetes

21 AORTO-ILIAC LESIONS Lesion type Type AType B Description * Unilateral or bilateral stenosis of CIA * Unilateral or bilateral single short ( ≤3cm) stenosis of EIA * Short ( ≤3cm) stenosis of infrarenal aorta * Unilateral CIA Occlusion * Single or multiple stenosis totaling 3-10cm. Involving the EIA occlusion not involving the origins of internal iliac of CFA

22 AORTO-ILIAC LESIONS Lesion type Type CType D Description * Bilateral CIA occlusion * Bilateral EIA stenosis 3-10cm long not extending into the CFA * Unilateral EIA stenosis extending tnto the CFA * Unilateral EIA occlusion that involves the origins of internal iliac and/or CFA * Heavily calcified unilateral EIA occlusion with or without involvement of origins of internal iliac and/or CFA * Infra-renal aorto-iliac occlusion * Diffuse disease involving the aorta and both iliac arteries requiring treatment * Diffuse multiple stenosis involving the unilateral CIA, EIA and CFA * Unilateral occlusions of both CIA and EIA * Bilateral occlusion of EIA * Iliac stenosis in patients with AAA requiring treatment and not amenable to endograft placement or other laesions requiring open aortic or iliac surgery

23 FEMORAL-POPLITEAL LESIONS Lesion type Type AType B Description * Single stenosis ≤10cm in length * Single occlusion ≤5cm in length * Multiple lesions (stenoses or occlusion),each ≤5cm * Single stenosis or occlusion ≤15cm not involving the infra geniculate popliteal artery * Single or multiple lesions in the absence of continuous tibial vessels to improve inflow for a distal bypass * Heavily calcified occlusion ≤5cm inlength * Single popliteal stenosis

24 FEMORAL-POPLITEAL LESIONS Lesion type Type CType D Description * Multiple stenoses or occlusions totaling >15cm with or without heavy calcifications * Recurrent stenoses or occlusion that need treatment after two endovascular interventions * Chronic total occlusion of CFA of SFA (>20cm, involving the popliteal artery) * Chronic total occlusion of popliteal artery and proximal trifurcation vessels
