ILLNESS
Patient was apparently alright 2 years ago when he developed pain in right calf muscle
while walking but he could still walk with effort. Pain was dull aching type , insidious in
onset and progressive in nature. It appeared after walking 500 meters and disappeared
after taking rest and reappeared on walking same distance. The walking distance has
gradually shortened over a few months and he developed pain at rest in the toes four
months back which is continuous and aching in nature aggrevated at night.
He noticed black discolouration over Right great toe 3 months ago which has progressed
slowly and has involved 2nd and tip of 3rd toe.He also felt numbness in the toes.

. But following no improvement, he was referred to KLE Hospital.

9. GENERAL PHYSICAL
EXAMINATION
 Patient is an elderly male of moderate built and nourishment . He is conscious ,
cooperative and well oriented to time ,place and person.
 VITALS-
 PULSE- 88 BPM in the Right radial artery with normal rhythm, volume and character.
 BLOOD PRESSURE- 130/80 mmHg in Right and Left Brachial artery and 120/70mmHg in
Right and Left Femoral artery with no radio femoral delay.
 RESPIRATORY RATE- 22 Breaths per minute
 TEMPERATURE is afebrile by palpation
o Pallor is present.
o No evidence of Odema, Icterus, Cyanosis, Clubbing or Lymphadenopathy.

10. SYSTEMIC EXAMINATION
 CNS- Higher mental functions are intact , No tremors.
 RESPIRATORY SYSTEM- Normal vesicular breath sounds heard, no
added sounds heard.
 CVS- S1,S2 heard, no added sounds.
 PER ABDOMEN- Abdomen is flat, umbilicus centrally placed, no
dilated veins , strain, scar. On Palpation abdomen is soft, no
tenderness, no guarding, no rigidity is present. On Percussion no free
fluid is present and normal bowel sounds are present on auscultation

11. LOCAL EXAMINATION

12. INSPECTION
 Slight pallor is present in both the legs.
 Muscle wasting is evident in calf muscles of right lower limb compared to left.
 Buerger’s Postural Test- Guttering of veins is evident on elevation of right limb to 30 degree.
 Signs of Ischemia- like thin and shiny skin, loss of subcutaneous fat, loss of hairs are present
on both limbs but no gangrenous change is seen in opposite limb.
 Loss of nail plate on great toe and brittle and deformed nails are present over other toes.
 Dry and shriveled Great toe , 2nd and 3rd toes. Blackening over toes present.Line of
demarcation present and no Skip lesions.
 Capillary filling time- 20 seconds
 Venous refilling time- 10 seconds

13. BUERGER’S POSTURAL TEST
 The patient is in supine position. Ask the patient to raise his legs one after the other keeping
the knees straight. The legs of normal individual remains pink even if raised to 90 degree. But
in case of an ischaemic limb elevation to a certain degree will cause marked pallor.
 The angle between the limb at which such pallor appears and the horizontal plane is known as
Buerger’s angle or Vascular angle.
 Vascular angle <30 degree- severe ischameia .If no pallor it indicates arterial occlusion.

14. PALPATION
 Right foot and leg is cold on palpation as compared to left limb. At the level of
thigh temperature is similar in both limbs.
 Dry gangrene felt as hard and shriveled area is present over Right greater toe,
2nd toe and 3rd toe with loss of sensation over gangrenous part and loss of
movement at metatarso-phalangeal joints. There is Hyperesthesia over dorsum
of right foot. No Crepitus present.
 Delayed capillary and venous refilling.
 No tenderness or pitting odema in adjacent normal limb.
 Reflexes of the limb like plantar reflex are intact.
 Ankle, hip and knee flexion and extension against resistance present.

15.  PULSATIONS- The condition of the arterial wall is normal with no special
character of pulse
 Crossed leg test- Oscillatory movements are absent.
 No Inguinal lymphadenopathy.

16. Crossed leg test
(Fuchsig's test).
 This is performed 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 the other
leg. The patient's attention is diverted
by taking history. The crossed leg will
show oscillatory movements of the foot
which occur synchronously with the
pulse of the popliteal artery. If the
popliteal artery is blocked, this
oscillatory movement will be absent.

17. AUSCULTATION
 No Bruits heard.
 Reactive Hyperaemia Test- red flush appears in 8 seconds
Reactive hyperaemia test is performed to know the severity of arterial ischaemia. This is done
by inflating a sphygmomanometer cuff around the limb to 250 mm Hg for 5 minutes. Then the
cuff is deflated and the time of appearance of red flush in the skin is noticed. It is 1 to 2
seconds in case of normal limb and it will be delayed in case of arterialocclusive disease and it
may never appear in case of severely ischaemic limb.

18. PROVISIONAL
DIAGNOSIS
 Peripheral Arterial Occulsive disease
affecting both lower limbs with
ischaemic gangrene of right greater
toe,2nd toe and 3rd toe secondary to
Atherosclerotic Vascular disease.
