Claudication distance: The patient complains after walking a distance, pain starts.Boyd’s classification:
Grade-I sometimes if the patient continues to walk pain disappears.Grade-II pain continues & patient can still walk with effort.Grade-III pain compels the patient to take rest

Paresthesia – numbness,pins & needles and other types of paresthesia in the skin of the foot. Due to- shunting of blood from skin to muscles.
H/O superficial phlebitis – swelling, redness and minor pain in the affected part.
Involvemet of other arteries.

• Marked pallor – sudden arterial obstruction. in embolism or Raynaud’s disease• Congestion and purple blue cyanosed – severe ischaemia and pregangrenous stage
![Page 16: perpheral vascular disease & gangrene examination](https://reader033.vdocuments.net/reader033/viewer/2022061116/546667e5b4af9f583f8b532e/html5/thumbnails/16.jpg)

3. BUERGER’S POSTURAL TEST:3. BUERGER’S POSTURAL TEST:PROCEDURE:The patient lies on his back, and asked to raise his legs one after the other keeping the knees straight.The legs of normal individual remain pink even if they are raised to 90˚.But in case of ischaemic limb elevation to a certain degree will cause marked pallor and the veins will be empty and guttered.Buerger’s angle or Vascular angle.<30˚ - severe ischaemiaIf not pallor – occlusive arterial disease is suspected.
![Page 18: perpheral vascular disease & gangrene examination](https://reader033.vdocuments.net/reader033/viewer/2022061116/546667e5b4af9f583f8b532e/html5/thumbnails/18.jpg)
Page 18
4. CAPILLARY FILLING TIME:4. CAPILLARY FILLING TIME:
• After elevating the legs, the patient is asked to sit up and hang his legs down by the side of the table.• A normal leg will remain pink as it was during elevated position.• But in ischaemic leg will first become pallor when elevated & gradually become pink in horizontal position.• The change of colour takes place slowly and is called CAPILLARY FILLING TIME.
![Page 19: perpheral vascular disease & gangrene examination](https://reader033.vdocuments.net/reader033/viewer/2022061116/546667e5b4af9f583f8b532e/html5/thumbnails/19.jpg)
Page 19
5. VENOUS REFILLING:5. VENOUS REFILLING:
•After keeping the limb elevated for a while if it is then laid flat on the bed, there will be normal refilling of the veins within 5 sec.•But in ischaemic limb it will be delayed.•If a normal limb is raised to about 90˚ there will be gradual collapse or guttering of the veins. •But in ischaemic limb the veins are seen collapsed either in horizontal position or as soon as it is lifted to even 10˚.

4. CROSSED LEG TEST (Fuchsig’s test)4. CROSSED LEG TEST (Fuchsig’s test)
• To detect popliteal pulsation.• The patient is asked to sit with the legs crossed one above the other so that the popliteal fossa of one leg will lie against the knee of other leg.• The crossed leg will show oscillatory movements of the foot which occur synchronously with the pulse of popliteal artery.• If popliteal artery is blocked, this oscillatory movement will be absent.

To provoke arteriospasm in Raynaud’s disease The patient asked to put hand in…..• Ice water – hand becomes white.• Warm water - hand become blue due to cyanotic congestion.

6. ELEVATED ARMS TEST:6. ELEVATED ARMS TEST:Performed when thoracic outlet syndrome is suspected.PROCEDURE:The patient is asked to abduct his shoulders to 90˚ and at the same time upper limbs are externally rotated fully.Now patient is instructed to open and close his hands for a period of 5 min.A normal individual can perform without difficulty.Patient will complain of tingling and numbness in the fingers.
![Page 26: perpheral vascular disease & gangrene examination](https://reader033.vdocuments.net/reader033/viewer/2022061116/546667e5b4af9f583f8b532e/html5/thumbnails/26.jpg)

7. ALLEN’S TEST:7. ALLEN’S TEST:To know patency of radial and ulnar arteries.The patient is asked to clench his fist tightly.The surgeon presses on the ulnar and radial arteries at the wrist.Now pressure is removed and colour of the hand is noted.If any artery is blocked the colour remains white, if patent the palm assumes normal colour.

8. BRANHAM’S SIGN:8. BRANHAM’S SIGN:
This is performed when arteriovenous fistula is suspected.A pressure on the artery proximal to the fistula will cause reduction in the size of swelling, disappearance of bruit, fall in PR.
![Page 29: perpheral vascular disease & gangrene examination](https://reader033.vdocuments.net/reader033/viewer/2022061116/546667e5b4af9f583f8b532e/html5/thumbnails/29.jpg)

9. Costoclavicular compressive 9. Costoclavicular compressive manoeuvre or test:manoeuvre or test:
Pateint’s radial pulse is felt.The patient throws shoulders backwards & downwards.This will compress the subclavian artery between clavicle and the first rib leading to reduction or disappearance of radial pulse.

AUSCULTATIAUSCULTATIONON
Listen along the course of all major arteriesSystolic bruit over an artery – turbulent bloodflow beyond the stenosisSystolic murmor – aneurysm.Continuous machinary murmor – arteriovenous fistulaBlood pressure of both arms are measured.Reactive hyperaemia test – to know severity of arterial ischaemia.

GENERAL GENERAL EXAMINATIONEXAMINATION
1. Atherosclerosis – examined thoroughly to exclude IHD, CVD, HTN, renal artery stenosis etc.
2. In embolic manifestation, the heart is examined for presence of cardiac murmor
3. Diabetes is often accompanied by atherosclerosis.
4. Peptic ulcer is sometimes accompanied with these diseases.
