René Leriche of Leriche’s Syndrome


What would be the best Treatment for this Patient (who has aorto-iliac occlusion)?

1. Smoking cessation and BP control

2. ASA and/or clopidogrel (Prevents MI, CVA , etc).

3. Cilostazol (Pletal/phosphodiesterase type 3 inhibitor – inhibits platelet aggregation and dilates vessels) 100 mg BID

4. Pentoxifylline (Trental/phosphodiesterase inhibitor with antihemorrheologic activities) 400 mg TID

5. Ramipril*

6. Statin (rosuvastatin 40 mg daily)

7. Stent

8. Axillo-femoral bypass; Aorto-fem bypass

9. Intermittent calf compression. Angiogenesis with injection of mononuclear cells.

*The imbalance between NO and Ang II activities associated with endothelial dysfunction and risk factors for CAD causes oxidative stress, which

results from excessive production of oxygen-free radicals which counteracts the effects of NO, stimulates expression of adhesion molecules and promotes adhesion of leukocytes to the endothelium. These actions cause an acute inflammatory response, proliferation of smooth muscle cells and production of extracellular matrix, all of which contribute to the pathogenesis of atherosclerosis. (Griendling and Alexander 1997). 


Arterial Diseases


A 60 y/o diabetic male presents with cramping pain in both calves with  walking 2-4 blocks. The femoral arterial pulses seem somewhat diminished in the groin, the left popliteal and left pedal pulses are diminished. The right pedal pulses are absent. The Ankle/Brachial index is 0.5 on the left and 0.1 on the right. There is no hair on the right toes and the patient has dependent rubor on the right. (see image which shows: Dependent rubor, Rest pain, note: Blanching on elevation would be apparent)

The patient most likely has severe occlusion of the:

A. distal aorta.

B. right iliac.

C. profunda femoris.

D. superficial femoral.

E. tibials.


Q image thumb

D. superficial femoral.

If the profundus were involved, the claudication would occur much earlier.


What is this an image of?

Q image thumb

Magnetic resonance angiography of the lower extremity demonstrating preocclusive

disease of the superficial femoral artery on the left and occlusion on the right.

The right profunda femoris artery is the source of a rich collateral network in this patient.

1. In the above patient who has superficial femoral arterial occlusion, under what conditions would it have been possible to have a more normal ABI on the right (ie .8 or .9) and still have poor circulation?



2. What is Osler’s sign or maneuver?

1. In the above patient, under what conditions would it have been possible to have a more normal ABI on the right (ie .8 or .9) and still have poor circulation?

When the vessels are calcified* as in diabetics. This does not allow practical use of ABI and thus one must resort to wave form analysis.

(Note -*Calcification is a most potent predictor of stent thrombosis)


2. What is Osler’s sign or maneuver?

Pseudohypertension because of calcified vessels.


in the Attached Image you see an example of a using wave form on a patient with ilio-femoral disease on the right.

A image thumb

What would be the treatment for this patient who has superficial femoral artery occlusion?

Treatment of superficial and common femoral and popliteal stenosis

•1. structured walking program

•2. Fem-pop bypass*


*absolute indication for surgery – rest pain and non-healing ulceration.


A image thumb

A 55 year old man is seen for progressive bilateral leg and calf pain with ambulation and relief with sitting down in a chair. History is positive for hypertension and the patient is on an ACE inhibitor.  Physical examination reveals an S4. Present BP is 130/60. He has a “simian gait” and complains of worse pain with extension of his back and improvement with bending forward. Calves are tender. Pedal pulses are questionably diminished. Which test will most likely be positive?

A.  Ankle/brachial index

B.  Femoral angiography

C.  Lumbar spine xray

D.  Lumbar MRI

E.  Venous doppler

D.  Lumbar MRI


Attached Image shows progressive narrowing of the spinal canal may occur alone or in combination with acute disc herniations.  Lumbar spinal stenosis (LSS) remains the leading preoperative diagnosis for adults older than 65 years who undergo spine surgery. 

A image thumb

 What is lumbar spinal stenosis?

Absence of pain or improvement of symptoms when seated assists in ruling in LSS. Patients with significant lumbar spinal canal narrowing report pain, weakness, and numbness in the legs while walking.  Compressed nerve roots become ischemic due to stenosis. This is the hallmark of neurogenic claudication. The pain is relieved when the patient flexes the spine by, for example, leaning on shopping carts or sitting. Flexion increases canal size. The most common nerve affected is the L5, with associated weakness of extensor hallucis longus. Neurogenic claudication pain is exacerbated by standing erect and downhill ambulation and is alleviated with  sitting, squatting, and lumbar flexion. 


Tibial and pedal artery occlusion

What is Phlegmasia Cerulean Dolens

Phlegmasia Cerulean Dolens*


Literally inflammatory (edematous), blue, and  painful, ie. painful, sky blue and inflamed! Due to primary venous insufficiency with secondary arterial insufficiency (not so in AF where emboli cause primary arterial occlusion and pallor occurs).

Most common cause is cancer, though may be obesity, old age, immobilization, or other procoagulant conditions (Factor V Leiden, etc) . 


*may get massive fluid loss with decreased BP, or even vasodilatory shock from inflammatory mediators. Phlegmasia alba dolens has to do with colateral veins allowing some drainage so that tissue ischemia does not occur.
