The semiological analysis of the peripheral pulse
[*] Sites
[*] Rate
[*] Rhythm
[*] Amplitude (pulse volume, intensity)
[*] character
PAD
Risk factors
- Age less than 50 years with diabetes, and one additional risk factor (e.g., smoking, dyslipidemia, hypertension, or hyperhomocysteinemia)
- Age 50 to 69 years and history of smoking or diabetes
- Age 70 years and older
- Known atherosclerotic coronary, carotid, or renal artery disease
Rate/rythm
Rate- beats/min
- count the number of beats over 15 seconds and then multiply by four
- Slow/irregular – 60 sec.!
Rhythm:
- Regular
- Irregular
[*] Complete arh.
[*] Extrasystolic arh.
[*] Respiratory arh.- NORMAL !!!
–In young
–the heart rate increases slightly during inspiration- vagal tone
Pulse intensity
–0, absent
–1, diminished
–2, normal
–3, bounding
Pulsus Paradoxus
[*] the blood pressure falls more than 15 mmHg in inspiration (20)
–Tamponade
(It represents an “exagerate” response)
Auscultation of the arteries

PAD
Cassification
- functional- spasm
- organic- obstruction of the blood flow:
- Acute
- Chronic
PAD
causes
- ATS; diabetes
- Buerger disease (Thromboangiitis Obliterans): segmental vascular inflammation, vasoocclusive phenomenon
PAD
Clinical Manifestation
Asymptomatic: Without obvious symptomatic complaint (but usually with a functional impairment).
Classic claudication: Lower extremity symptoms confined to the muscles with a consistent (reproducible) onset with exercise and relief with rest.
“Atypical” leg pain: Lower extremity discomfort that is exertional but that does not consistently resolve with rest, consistently limit exercise at a reproducible distance
Critical limb lschemia: Ischemic rest pain, nonhealing wound, or gangrene
Intermittent claudication- muscle pain (calf muscle)
– ache, cramp, fatigue, during exercise and relieved by rest.
–claudication index
PAD Physical exam:
–Absence of the peripheral pulses
–Hair loss, cold legs, pallor (trophic changes)
–Murmur- stenosis
–ulcer, gangrene
PAD Differential DG
[*] Peripheral neuropathy
[*] Osteoarthritis of the hip or knee
[*] Venous pathology
[*] Compartment syndrome ( pressure within a limited space compromises the circulation and function of the tissues within that space)
[*] Muscle spasms or cramps
[*] Restless leg syndrome
1.Resting Ankle-Brachial Index (ABI)
Step 1: the blood pressure cuff placed on the arm is inflated over the artery until the pulse ceases
Step 2: Turn on the Doppler and place the probe in the area of the pulse; the cuff is slowly deflated
The corresponding sphygmomanometer pressure at the instant the pulse returns provides the systolic blood pressure.
Step 3: the same manner for leg

symptoms
5 P-s”:
- Pulselessness (distal of the level of occlusion)
- Pain
- Palor
- Paresthesia
- Paralysis
–Number 6 of the “P” is recently added: prostration.
Buerger disease (trombangiitis obliterans)
- Male, young, heavy smoker
- Small and medium sized arteries and veins
- Lower limbs- usually
- distal limb ischemia: cyanosis, pallor, cold limb, ulcerations or localized gangrene of the digits; secondary Raynaud’s phen.
- Superficial thrombophlebitis
Amputation is common
[*] The Stanford classification divides dissections into 2 types: type A and type B.
- Type A involves the ascending aorta (corresponds to the DeBakey types I and II)
- Type B involves the aorta distal to the left subclavian artery (DeBakey type III).
The DeBakey- 3 types of dissections:
- Type I involves the ascending aorta, aortic arch, and descending aorta.
- Type II involves the ascending aorta.
- Type III refers to the descending aorta distal to the left subclavian artery
Clinical Manifestation of Aortic dissection
- Chest pain: typically with an abrupt and maximal intensity onset, described as ripping or tearing
- Anterior thoracic pain- anterior arch or aortic root dissection
- Neck or jaw pain- aortic arch dissection
- Interscapular pain radiating to lower back or abdomen- descending aorta dissection.
- Blood pressure: decreased due to the cardiac tamponade, hypovolemia or increased due to cathecolamine reaction or the underlying hypertension; significant interarm difference
- Dyspnea- heart failure or tracheal or bronchial compression.
- Acute aortic regurgitation with acute cardiac failure signs
- Acute myocardial infarction
- Cardiac tamponade: muffled heart sounds, hypotension, pulsus paradoxus, jugular venous distension, Kussmaul sign
Neurological signs:
[*] syncope, cerebrovascular accident, peripheral nerve ischemia, recurrent laryngeal nerve compression (resulting in hoarseness), irritation of the cervical sympathetic ganglia with Claude-Bernard-Horner syndrome (unilateral ptosis, miosis, and anhidrosis)
Gastrointestinal manifestations
involvement of the renal artery, abdominal aorta
[*] DVT of the lower limbs
- Distal
- Proximal- the highest risk of PE–Phlegmatia caerulea dolens: due to massive ileofemoral veins obstruction; the leg is usually markedly edematous, painful, and cyanotic
- Plegmatia alba dolens: massive thrombosis and associated arterial spasm; the leg is often pale with diminished or absent distal pulses
DVT
Clinica Manifestations
- Edema
- Swelling of the leg
- leg pain
- Tenderness
- Erythema
- Superficial distended veins
- Pulmonary thrombembolism as a primary manifestation- dyspnoea, cyanosis, tachycardia (Mahler sign), fever (Mikaelis sign)
- Homans’s sign (pain- the calf muscles on forced dorsiflexion of the foot)
- Lowenberg sign (the cuff compression test): calf pain at a pressure lower than 180 mmHg
- Lisker’s sign: pain during the percussion of the anteromedial side of the tibia.
Upper limb DVT-
[*] cancer, trauma, catheter or sustained effort (the abduction of the arm)
