Presentation
Abstract A study of the results of lumbar sympathectomy in the treatment of peripheral vascular occlusive disease has been presented. Results continue to be encouraging in properly selected patients, as they have been since 1947. [ncbi.nlm.nih.gov]

Gangrene
Despite repeated infusions of urokinase, he developed progressive bilateral gangrene of both legs necessitating bilateral below-knee amputations. The second patient developed similar symptoms after smoking cocaine. [ncbi.nlm.nih.gov]
[…] and amputation -Often preceded by claudication • Nonhealing wounds ulcers -Trivial trauma may cause wounds in pts with PVOD -Commonly located on toes, or distal foot -Usually painful with eventual gangrene • Erectile dysfunction -Due to obstructed blood [accesssurgery.mhmedical.com]
Dry gangrene is present over Right great 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. 3. [slideshare.net]
As the disease worsens, the leg becomes cold with blackening and drying up of skin (Gangrene). This stage of PAOD is known as a LEG ATTACK, and requires immediate treatment in the form of Revascularisation. A typical LEG ATTACK leading to Gangrene. [practo.com]

Thrombosis
In contrast, a patient who has had an arterial bypass that suddenly fails or who suffers acute thrombosis of a distal artery in the presence of occlusive disease may have extensive thrombosis involving distal vessels. [iame.com]

Differential diagnosis The differential diagnosis of pain in the lower limb when walking includes sciatica and spinal stenosis, deep vein thrombosis, entrapment syndromes and muscle/tendon injury. [patient.info]
Thrombolysis and thrombectomy are used in cases of arterial thrombosis or embolism. [en.wikipedia.org]
When the plaque ruptures, this results in thrombosis that obliterates the vascular lumen, triggering the acute syndrome. [revespcardiol.org]

Calf Pain
For example, if a patient stops primarily due to shortness of breath after only a few minutes of exercise, he or she is unlikely to benefit from revascularization even if there is associated calf pain. [iame.com]
Symptoms vary from calf pain on exercise (intermittent claudication) to rest pain (critical limb ischaemia), skin ulceration and gangrene. [patient.info]
Calf pain is the most common location for leg cramps. If the blockage or plaque formation is farther up the leg, the pain from claudication may be felt in the thigh. [medicinenet.com]
If there is extensive infection of the foot with gas, calf pain, or systemic sepsis, the patient may require amputation as an initial therapy. [thoracickey.com]

Paresthesia
Patients with moderate occlusive disease may have many of these findings, but paralysis and paresthesia indicate critical limb ischemia (CLI): impending tissue loss and the need for immediate intervention. [iame.com]
Ask the patient if she or he has experienced numbness, tingling (paresthesia), paralysis, muscle weakness, or sudden pain in both legs, which are all signs of aortic bifurcation occlusion. [medical-dictionary.thefreedictionary.com]
Paresthesia at rest may be indistinguishable from that due to diabetic neuropathy, although in the latter the paresthesia is usually bilateral, symmetrical, and with a "sock distribution." [revespcardiol.org]
It features with pain, pale, paresthesia and pulseless of limbs. [journals.plos.org]

Tingling
Therefore revascularization is urgent if the extremity is becoming weak or loses sensation (this means loss of fine touch or two-point discrimination, not merely a sensation of tingling). [iame.com]
Ask the patient if she or he has experienced numbness, tingling (paresthesia), paralysis, muscle weakness, or sudden pain in both legs, which are all signs of aortic bifurcation occlusion. [medical-dictionary.thefreedictionary.com]

Sciatica

Workup
This chapter will cover epidemiology, basic science, diagnostic workup, and medical treatment of peripheral vascular disease. Treatments of acute and chronic limb ischemia, open and endovascular, will be discussed. [thoracickey.com]
Figure 1 When otherwise occult, the source of embolism should be sought, including a cardiac workup and arterial studies to rule out aneurysm or significant plaques. The later may include ultrasound, CT, or MR imaging. [iame.com]
Treatment
After adjusting for endogenous choice of initial imaging modality, 30-day treatment costs were US 3500- 4300 lower (P 0.001) for patients with initial CE-MRA. [ncbi.nlm.nih.gov]
Prognosis
The prognosis following amputation is poor. [patient.info]
Treatment and prognosis Primary treatment strategy according to TASC severity: TASC A: endovascular therapy TASC B: endovascular therapy TASC C: surgical therapy (if the patient is fit for surgery, otherwise endovascular therapy) TASC D: surgical therapy [radiopaedia.org]
Statins, by preventing accompanying coronary or cerebrovascular incidents, also improve prognosis and survival of PAD patients. [escardio.org]
Differentiating between the 2 concepts is important in order to establish the therapeutic indication and the prognosis in patients with PAD. [revespcardiol.org]
[…] leading to under-diagnosis and under-treatment of the disease. 5 The most common symptom of PAD is intermittent claudication (IC) affecting the calf muscles, which may be present in as few as 10% of patients. 5 Symptomatic PAD patients have a worse prognosis [racgp.org.au]
Etiology
The etiology is still unclear but viral and immunological hypothesis have been postulated to explain the potential pathophysiological mechanism. [journals.plos.org]
[…] aortic PAD was compiled in 2013, combining the 2005 and 2011 guidelines. [32] Prognosis [ edit ] Individuals with PAD have an "exceptionally elevated risk for cardiovascular events and the majority will eventually die of a cardiac or cerebrovascular etiology [en.wikipedia.org]
Epidemiology
[…] that develops due to a progressive stenosis or the occlusion of the arterial vessels of the arm, or - more often - of the leg. see also: intermittent claudication 2 Pathogenesis PAD develops on the basis of an arteriosclerosis in 90% of the cases. 3 Epidemiology [flexikon.doccheck.com]
Finally, from an epidemiologic point of view, the association between the ABI and the presence of vascular disease in other territories is also very interesting. [revespcardiol.org]

Pathophysiology
Further pathophysiologic, histopathology and immunologic research is required to explore the underlying biologic mechanism. [journals.plos.org]
From the pathophysiologic point of view, ischemia of the lower limbs can be classified as functional or critical. [revespcardiol.org]

Prevention
Rates of preventive practices were lowest in the subgroup of PVD patients without a history of coronary or cerebrovascular disease. CONCLUSIONS: Preventive therapies are under utilized in patients with PVD. [ncbi.nlm.nih.gov]
Our surgeons specialize in the diagnosis, prevention and management of these blockages, whether through medications, minimally invasive surgery or major open surgery. [vascular.surgery.med.ufl.edu]
For patients with symptomatic PAD, the focus must be mainly on prevention of ischemic complications and prevention of progression of the atherosclerotic process. [escardio.org]
